Alnico magnets are made primarily from aluminium, nickel, cobalt, copper, iron and sometimes titanium. They can be either cast or sintered.

 

Sintered Alnico

Sintered alnico is made from a powdered mixture of ingredients that are pressed into a die under tons of pressure, sintered in a hydrogen atmosphere and then cooled either within a magnetic field or without (anisotropic Vs Isotropic).

Cast Alnico

Cast Alnico melted and poured into a mold. Once solidified, the material is rough ground and then heat-treated and cooled, sometimes in a magnetic field. When treated in the presence of a magnetic field, the magnet is called anisotropic. This orients the material to take on maximum magnetization and allows a higher gauss level. A cast magnet that is not heat-treated in a magnetic field is called Isotropic. After heat treatment and cooling, the material can be ground to specific tolerances and then magnetized.

Attributes of both Cast and Sintered Alnico

• Very temperature stable great for high heat applications
• Maximum working temperature 525ºC - 550ºC
• May be ground to size
• Does not lend itself to conventional machining (Hard and Brittle)
• High residual induction and energy product compared to Ferrite material
• Low coercive force compared to Ferrite and rare earth materials (more subject to demagnetization)
• Most common grades of Alnico are 5 and 8

Applications of Alnico Magnets

Magnetizing and Handling

Magnetizing is done after the magnet has been machined to the correct tolerances. Care should be taken when handling alnico material since it is brittle and chip or break if dropped on a hard surface. Also, because it has a low resistance to demagnetization, it will lose power if it is stored improperly (poles repelling each other). For best results, store magnetized alnico so that pieces are attracting each other, or with a steel keeper.

Machining

Alnico is a very hard and brittle material and does not lend itself to conventional machining. The STAR TRACE Employs Experienced Machinists and the proper equipment to grind alnico to its require Ship.

Ferrite Magnets are composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors.

 

Manufacturing Ferrite Magnets

A powdered mixture of strontium carbonate and iron oxide is injected into either a wet press or dry press for forming. During this pressing process, a magnetic field is applied in the direction of preferred magnetization to orient the material and increase the magnet's performance potential. This magnet is considered “oriented”. If not exposed to a magnetic field at time of formation, it is called “non-oriented” (Isotropic).

After the molding process, the material is then sintered at about 1010OC. This process is similar to that of kilting ferrite pottery, thus the popular name “Ferrite” magnet.

Lastly, the magnet is finish-ground to size with a diamond-bladed grinding wheel, magnetized, and inspected for shipment.

 

Attributes of Ferrite Magnets

» High intrinsic coercive force

» Tooling is expensive

» Least expensive material compared to alnico and rare earth magnets

»Lower service temperature than Alnico, greater than rare earth

» Finishing requires diamond cutting or grinding wheel

» Lower energy product than alnico and rare earth magnets

» Limited to simple shapes due to manufacturing process

» Most common grades of ferrite are 1,5 and 8 (1-8 possible)

» Grade 8 is the strongest ferrite material available

Application of Ferrite Magnets

• Speaker magnets
• DC brush less motors
• Magnetic Resonance Imaging (MRI)
• Used in magnetic assemblies designed for lifting, holding, retrieving and Separating
• DC permanent magnet motors (used in cars)
• Separators (Separate ferrous material from non-ferrous)
• Magnetos used on lawnmowers,and outboard motors

Tolerances

Pressed dimensions are either +/- 2% or +/- 0.5mm whichever is greater. Cut dimension are either +/- 3% or +/-0.5mm, whichever is greater. Thickness tolerances are normally ground to +/- 0.1mm.

Visual imperfections such as cracks, porosity, voids, surface finish, etc., (commonly found in sintered ceramic magnets) do not constitute cause for rejection.

Machining

Since ferrite material is so brittle, it requires special machining techniques and equipments. We are fully equipped to cut and grind ceramic material to your specifications.

Magnetizing and Handling

Ferrite magnet material is extremely brittle and can chip or break if dropped on a hard surface, or if allowed to “Jump at” an attracting object. Handle with care.

The weakest grade of Ceramic material is grade 1, which is typically non-oriented. Grades 5 and 8 are oriented ceramic material. Grade 8 is the strongest ceramic magnet material available (Refer to properties chart below).

When making magnetic assemblies with ferrite it is typically easier for production purposes to magnetize the product after assembly.

The material goes through a calendering process and is formed into sheeting or strip. It can then be easily machined to size and magnetized. High-energy flexible magnet are anisotropic (oriented), whereas the regular flexible material is not.

Therefore, high-energy magnets are limited to magnetization through the Thickness, and are similar in strength to a Grade 1 ceramic magnet.

Attributes of Flexible Magnet

› High resistance to demagnetization

› Free form chipping, cracking or shattering Inexpensive

› Easy fabrication and handling

› High energy product vs. regular flexible material

› Low curie point, not good in heat applications

› Adhesive or plain

Applications of Flexible Magnet

› Magnetic Assemblies

› Motors

› Sensors

› Latches

Hinged steel belt chip conveyor
It has been specially designed keeping in mind the hazards that are normally encountered with conventional chips and swaft conveyors. The hinged steel belt is pressed in extra heavy duty sheet and perfect guiding of rollers ensures minimum friction and noise free operation: the body compact in size and occupies small space but due to extra chip space can handle large volume of chips. The continuous operation ensures least machine down time and minimum labour.

Application:
cnc turning centers, cnc machining centers, transferline, multispindle atuomats, spm's, heat treatment furnaces and press shops.

Magnetic plan sheet type conveyor
fine, light and sharp chips generated from gear shaves, gear hobbers, spline cutting machines, spm's, deep hole drilling machines, broaching machines, press shops and heat treatment shops. Coming with large amount of coolant tend to escape with the coolant and cause damage to the pump and effects surface finish. Plain sheet magnetic conveyors help attract ferrous chips from coolant and separates coolant from chips. Thus the coolant is free from chips and the conveyor acts as magnetic filter for the coolant.

The moving permanent magnets mounted on endless chain underneath the stationery stainless steel sheet attracts ferrous chips and slide them on plate to the discharge end. The coolant separated from chips flows to the coolant tank through an over flow so that even floating chips get attracted by moving magnets and get conveyed.

Magnetic plain sheet type conveyors being sleek in construction can be introduced into small cross sectional openings in machine tools. Since conveyors are custom built, different configuration and profiles can be made to suit specific applications.

The rotary action not only prevents materials from briding, but it improves magnetic separation by agitaing cohesive powders.
It is manufactured as independent unit with Rare Earth Ndfeb Magnets in 25 mm Dia Tube. These are manufactured with manual and easy clean design. Sizes manufactured 300 x 300mm - 15 M3/hr. 400 x 400mm - 25 M3/hr.

In many branches of industry STAR TRACE Overband magnetic separators and suspension magnets have become indispensable for decades. They are used for removing magnetic parts from non-magnetic materials in order to project crushers, mills, processing plants etc. against too much wear and damage. They serve for cleaning non-magnetic bulk goods with iron contamination, for instance cleaning of foundry sand, coal and the like. They are used for recovering magnetic material from ore, steel mill slag etc.

 

Generally, overband magnetic separators and suspension magnets are installed above conveyor belts, vibratory feeders or chutes. They pick up ferrous metal parts from the bulk goods. In most cases, the magnets can also be installed in an existing installation without much expense.

 

When using overband magnetic separators and suspension magnets, many factors must be considered for the various applications, and it is impossible to list them all in a brochure. Each application, each material and each kind of conveying involves different problems.

 

Owing to the shape (demagnetization factor), long, bar-shaped and large iron parts can be better separated than short, cube shaped bulbous and small iron parts. he efficiency of the overband magnetic separator or suspension magnet depends on the pole size, pole distance, field intensity in the conveyor burden, lines of the material to be separated.

Large burden depths, large lump sizes, sticky or humid material render the separation more difficult.

RECTANGULAR SUSPENDED MAGNETS

Star Trace has been using space age technology to design the performance of their Suspended Magnets over any belt conveyor, vibratory feeder or inclined chutes. Ideally suited for removing tramp iron in quantities where continually discharging magnetic separators are necessary. Iron is extracted against gravity from the flow of material and held firmly to the magnet face until the magnet is de-energised. The best position for installation is it an angel over the conveyor head pulley or at the discharge point of a feeder, where the material fans out and is loose. In this position the magnet will remove more iron belt speeds (Fig. 1) looking at it costwise, this installation provides the best tramp iron removal for the money invested. Other installations have been made with the magnet suspended parallel to and above the conveyer. In such applications it is necessary to use a stronger magnet because tramp iron must be pulled through a fairly stable bed of material. Cleaning is simple-the operator just swings the magnet away from the conveyor, turns off the current and the tramp iron drops free.

IN-LINE AND CROSS-BELT MAGNETIC SEPARATORS

The In Line or cross belt magnetic separators provide a continuous and automatic discharge of collected tramp iron. A cleated belt revolves around stationery rectangular electro magnet suspended over the belt. Any iron coming on the conveyor is attracted by the magnet and discharged automatically by the cleated. Rubber canvas belt having its own independent drive. This is especially desirable where the magnet removes large quantities of tramp iron and hence never requires cleaning or stopping of the main conveyor.

The in-line suspended separator automatically discharge tramp iron in the same direction as the conveyor travels (Fig. 2) installed at an angle over the material discharge, and has the added advantages of removing long pieces of iron such as rods. Since the self cleaning belt of the in-line separator that can safely handle of jamming and tearing up a long section of expensive conveyor belting.

The cross-belt magnetic separator (Fig. 3) automatically discharges removed iron at right angles to the main conveyor and can be installed anywhere and in some cases over the material discharge.

The STAR TRACE magnetically coupled pumps are centrifugal types of fully encapsulated construction. The pumps are rated for continuous duty and is ideally suited for recirculation applications. The unit can be used with mild acids or alkalis, since the only components in contact with the pumped fluid are plastic and ceramic with a rulon bearing and a viton O- ring. (see Chemical compatibility.) Magnetically coupled pumps offer a number of advantages over conventional centrifugal pumps type.

» Leak paths are eliminated and friction and power consumption are reduced as there are no rotating seals.

» All 'wetted' components are formed from advanced plastic materials and have a high resistance to aggressive fluids.

» Transmission of heat from the pumped fluid to the motor is reduced.

INSTALLATION
The pump can be connected to pipework using suitable BSP fittings such as jubilee clips. The pump mounting plates have several fixing option. Flexible hoses with different internal diameters may be used (avoid over tightening as this may cause damage to the ports). The pump and pipework should be adequately supported and correctly fitted to avoid shock loading and strain on the pump and its ports. The pump not be mounted vertically with the ports below the motor.

OPERATION AND MAINTENANCE
The pump should have flooded suction since it does not self prime. Filters or restrictions should not be situated before the pump inlet. When priming, operate the pump in short 10 second cycles to facilitate the clearing of air. Ensure that there are no leaks or blockages in the associated pipework. The pump should not be operated against a closed valve for longer than 30 seconds. Where the pumped fluid causes coating or deposition, periodic cleaning of pumping internals may be necessary. This can be achieved by flushing through with an appropriate cleaning agent. The pump casing should be adequately ventilated to avoid overheating the motor. The motor is protected by the magnetic coupling should the impeller stall. do not run the pump dry.

Aerodynamically shaped with a solid stainless steel nose cone, the flow through design of the Bullet Magnet allows the magnet to be used anywhere in a pneumatic line system. It can be used ahead of processing equipment and bulk load out to assure product purity and protect machinery from tramp metal damage.

The nose cone diverter and magnet assembly of the Bullet is designed to maintain a balanced flow through the housing thereby maintaining uniform velocity in line flow. Ideal for dilute phase systems, typical Bullet Magnet applications include: movement of powder and granular flour, chemical, plastic, food stuff, pharmaceutical and mineral materials.

The STAR TRACE Bullet Magnet is easily installed with compression type couplings and is available in sizes ranging from 3” to 6” diameters. Rare earth Bullet Magnets provide an exceptionally powerful magnetic field to capture fine particles previously unattainable. He Rare Earth Bullet Magnet is easily cleaned by opening the hinged door to remove the magnet from the line. Once the magnet is away from the line a quick pull on the magnet element allows all captured tramp metal to fall off.

Round and square magnetic tubes

Individual Star Trace magnetics tubes in either round or square styles are available for customers desiring to fabricate their own systems for special applications requiring non-standard spacing or tube arrangement. Ruggedly constructed from 304 stainless steel, Both styles have tapped mounting holes at each end for easy installation.

The one inch diameter round tubes have 1/4"-20 mounting holes and the one half inch ceramic square tubes have 3/8"-16 mounting holes. Standard tube sizes range from 4" to 48" long.

Grates

Material consistency and compactability which influence flow characteristics are important factors in grate magnet applications. Awareness of material with tendencies to bridge between the magnet tubes is necessary for positive flow.

Diverter systems are helpful in directing the material to the magnets, but diverters can tend to increase bridging and reduce uniform flow. It is important that material have a natural product flow.

Round Tube Type

Magnetic grates deliver ferrous tramp metal separation in bins, chutes, drawers, hoppers and circular enclosures. Star Trace grates are constructed with one inch diameter magnetic tubes placed on two inch (2) centers in heavy duty 1/8" thick 2" wide 304 stainless steel framing.

The round magnetic grates are available in 30 standard diameters from 4 inches through 36 inches. Special sizes are also available. Each of these round grates can be equipped with diverters. The high strength magnet material used in Star Trace grates has an approximate magnetic loss of 1/2 of 1 percent per year.

Square Tube Type

Square tube magnet separation grates are ideal for heavy duty applications where high product volume is involved. Having strong magnetic fields, the square tubes are installed with the leading edge toward the material flow.

This positioning helps eliminate material bridging and provides a protected collecting area along the bottom of the magnet where ferrous tramp metal remains out of the material flow. Constructed from 304 stainless steel, and mounted in a 1/4: thick x 2-1/2" high stainless steel bar framing, Star Trace square tube magnet grates deliver heavy duty performance and long service life. Available in sixty-six standard square of rectangular sizes, these square tube grates are the optimum tramp metal separation device for point-of-entry receiving areas.

Water is the most commonly used media for cooling, be it internal combustion engine, compressors, furnaces, Air conditioners etc. the reason being it absorbs maximum heat per cubic centimeter and does not become a hazard. Oil and other liquids carry much less heat and are fire hazards too. Water, as obtained naturally, has one major problem i.e. tendency to form scales on the pipes or other areas in which it is circulation especially when hot.

This scale formation results in:

1. Chocking of passage resulting in less flow and consequently consumption of more energy

2. Non-Conducting layer being formed between heat source and water, which is taking away that heat, thus reducing efficiency of cooling. This can be eliminated by using water softening plants which are cumbersome, difficult to operate, incur recurring costs and can not be utilized in all cases due to paucity of space. However all these problems can be solved! Thanks to the revolutionary technology of treating water which is no available!! 

Magnetic Anti Scale Unit

• It requires No chemicals, No salts, No energy, No backwashing

• Easy to Install

• Just connect directly to the main water supply.

• Does Not Affect the quality or taste of the water

It Works By

It is based on a process which treats water without altering its mineral composition. Water flows through a magnetic coil from highly efficient permanent magnets. In this cell the water crosses a magnetic field perpendicular to the lines of induction. This contact polarizes the molecules contained in the water, thereby disrupting the normal crystallization process of mineral salts such as calcium and magnesium. Once these salts have been physically modified in this way, they lose their ability to attach themselves to the lining of pipes and tanks.

Operating Principle

Molecules (CaCo3, Potassium, Manganese, etc.) which are in natural suspension in water, tend to form macro molecules which, if nothing is done, continue to coagulate, causing scale to collect in the pipes with resultant reduction in flow and increased consumption of energy.

Technical Principles

Permanent magnets are installed along the entire length of the appliance, the lines of magnetic flux being captured by a mild iron cylinder (care being taken that the flow-rate is not affected.)

What Is The Result?

When passing through the magnetic field, the macro-molecules are polarized in such a way that their conglomerate structure is deliberately disorganized so that their original molecular state of natural suspension in the water is re-established. After passing through this induced field, they will retain a residual magnetic charge for more than 30 hours (which is substantially longer than the water renewal cycle, which does not exceed 12 hours); they cannot therefore recoagulate. In the case of ferruginous water, ferrous and ferric welding residues, an anti-corrosion process is established (thus eliminating electrolysis phenomena).

Round and Square Magnetic Tubes

Individual Star Trace magnetics tubes in either round or square styles are available for customers desiring to fabricate their own systems for special applications requiring non-standard spacing or tube arrangement. Ruggedly constructed from 304 stainless steel, Both styles have tapped mounting holes at each end for easy installation.

The one inch diameter round tubes have 1/4"-20 mounting holes and the one half inch ceramic square tubes have 3/8"-16 mounting holes. Standard tube sizes range from 4" to 48" long.

Grates

Material consistency and compactability which influence flow characteristics are important factors in grate magnet applications. Awareness of material with tendencies to bridge between the magnet tubes is necessary for positive flow.

 

Diverter systems are helpful in directing the material to the magnets, but diverters can tend to increase bridging and reduce uniform flow. It is important that material have a natural product flow.

Round Tube Type

Magnetic grates deliver ferrous tramp metal separation in bins, chutes, drawers, hoppers and circular enclosures. Star Trace grates are constructed with one inch diameter magnetic tubes placed on two inch (2) centers in heavy duty 1/8" thick 2" wide 304 stainless steel framing.

The round magnetic grates are available in 30 standard diameters from 4 inches through 36 inches. Special sizes are also available. Each of these round grates can be equipped with diverters. The high strength magnet material used in Star Trace grates has an approximate magnetic loss of 1/2 of 1 percent per year.

Square Tube Type

Square tube magnet separation grates are ideal for heavy duty applications where high product volume is involved. Having strong magnetic fields, the square tubes are installed with the leading edge toward the material flow.

This positioning helps eliminate material bridging and provides a protected collecting area along the bottom of the magnet where ferrous tramp metal remains out of the material flow. Constructed from 304 stainless steel, and mounted in a 1/4: thick x 2-1/2" high stainless steel bar framing, Star Trace square tube magnet grates deliver heavy duty performance and long service life. Available in sixty-six standard square of rectangular sizes, these square tube grates are the optimum tramp metal separation device for point-of-entry receiving areas.
