Adjustment of magnet yoke and drum: The magnet yoke is mounted on the stationary drum shaft and its position can be adjusted (+/-35) by a lever at the end of the drum shaft to optimize runing conditions in accordance with tank design and type of ore. The gap between tank and drum, which determines the pulp  flow speed, can be adjusted vertically by shims inserted under the bearing housing and shaft support. Horizontal adjustment is by slotted holes.

Magnetic Roll Separator 
Magnetic roll separator is a roll type dry magnetic separator with fixed magnet having high field intense and gradient. The magnets used in the Magnetic roll separator for silicas and made of alloys of rare earth elements are more powerful as compared to other magnets. Magnetic roll separator for silicas generate high attraction forces on the magnetic roll due to their properties and special magnetic series. The obtained high magnetic attraction forces have low magnetic sensitivity and therefore they make it possible to separate very fine low magnetic minerals with a high recovery.

The most distinguishing property of Magnetic roll separator is the used magnets that are an alloy of rare earth elements produced domestically and more powerful. Magnetic systems has a number of standard sizes in which the high gradient separator is produced, and all of these sizes only require a low installation height. It is also possible to make a system in accordance with customer specifications. Depending on the requirements made and the application, a choice can be made for a single stage system or for multiple magnet rolls under one another. This results in an even higher degree of iron separation.

Silica sand processing flotation machine:
Froth Silica sand processing flotation machine is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In Silica sand processing flotation machine, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the change in the surface free energy when the attachment occurs. These bubbles rise through the slurry and are collected from the surface. To enable these particles to attach, careful consideration of the chemistry of the pulp needs to be made. These considerations include the pH, Eh and the presence of Silica sand processing flotation machine reagents. The pH is important as it changes the charge of the particles surface and the Eh effects the chemisorption of collectors on the surface of the particles.The addition of Silica sand processing flotation machine reagents also effects the operation of these processes. The most important chemical that is added is the collector, This chemical binds to the surface of the particles as it is a surfactant. The main considerations in this chemical is the nature of the head group and the size of the hydrocarbon chain. The hydrocarbon tail needs to be short to maximize the selectivity of the desired mineral and the headgroup dictates which minerals it attaches to.
The frothers are another important chemical addition to the pulp at it enables stable bubbles to be formed. This is important as if the bubble coalesce, minerals fall off their surface. The bubbles however should not be too stable as this prevents easy transportation and dewatering of the concentrate formed. The mechanism of these frothers is not completely known and further research into their mechanisms is being performed.

Depressants and activators are used to selectively separate one mineral from another. Depressants inhibit the Silica sand processing flotation machine of one mineral or minerals while activators enable the Silica sand processing flotation machine of others.

There are a number of cells able to be used for the Silica sand processing flotation machine of minerals. these include Silica sand processing flotation machine columns and mechanical Silica sand processing flotation machine cells. The Silica sand processing flotation machine columns are used for finer minerals and they typically have a higher grade and lower recovery of minerals than mechanical Silica sand processing flotation machine cells.

  • Weight: 0.5-3.5 T
  • Voltage: 380V
  • Material: Steel

Dewatering screen for silica
Whilst enjoying immense popularity for many years on small horizontal and  inclined screens , star trace is the first company in the world to perfect this simple drive arrangement on large Dewatering screen for silica. This single development has resulted in tremendous advantages as far as reduced maintenance, compactness and simplicity are concerned. Besides the simplicity of the drive, many other features have been incorporated to provide a machine which is specifically designed for heavy duty applications, long life, and low operating and maintenance costs, at a competitive price. The standard range of Dewatering screen for silica is presented later in the brochure, and these are normally available on short delivery. 

Advantages:

The advantages of Dewatering screen for silicas is that use of the following equipment has now been rendered unnecessary:
External drive, with vee-belts or cardan shafts.Oil bath oscillators, with synchronising gears and oil leaks.

Motor support stand, or overhead structure for motor support.Snubbers - the screen-mounted drive has eliminated the need for snubbers to reduce damage to vee-belts and external motors during the large oscillations that normally occur during stopping.Bearing failure is limited to the bearing itself. Particles from a failed bearing cannot circulate in an oilbath and cause possible damage to other bearings and synchronizing gears. Compactness - screens can be positioned very closely with a minimum of space wastage.A vibrator motor needing reconditioning can easily be exchanged for a standby unit, with a minimum of downtime.Due to the absence of gears and vee-belts, the units use less power than conventional drives.
