Vibrating Screens

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 screens. 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 screens is presented later in the brochure, and these are normally available on short delivery.
Advantages:

The advantages of of dewatering screens 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 synchronising 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.

Screen separators is a unique particle size gradable separator designed for greater capacity per meter square of screening area & over size material discharge with relatively much less percentage fines than other screening machines.

Industries Catered:

• Mineral processing pharmaceutical
• Ceramic animal feed
• Food & beverages effluent & waste
• Abrasive industries water treatment.

Working Principle:

The top weight on the motor shaft rotates in a plane close to the center of the mass of assembly. Rotation of the top eccentric weight creates vibration in the horizontal plane which causes material to move across the screen cloth to periphery. Increasing the top eccentric mass, increases the horizontal throw, causing oversize material to discharge at a faster rate. The bottom eccentric weight rotates below the center of mass, creating tilt on the screen, giving vibration in vertical & tangential planes. Increasing the vertical component of motion, which promotes turn over of material on the screen surface helping maximum quantity of under size material to pass through the screen. The vertical motion also minimizes blinding of screen by “near size” particles. The tangential component of motion is controlled by the angle of lead given to bottom weights with relation to top weight.

Variation in lead angle controlled the spiral pattern of material travel over the screen cloth. Speed & flow pattern of material travel over the screen cloth can be set by the operator for maximum throughout & screening efficiency for any screen able product- wet or dry, coarse or fine, heavy or light, hot or cold. Typical material passes rapidly through the screen during its travel to the periphery. The over size material get continuously discharged through a tangential outlet.

The circular motion screens is a new generation vibratory screening machine characterized by low profile, efficient protection of support structure from vibrating masses and virtually noiseless operation. The various versions of these circular motion screen permit its Use for wet and dry screening, coarse and fine Separations and are widely used in steel mills, mineral beneficiation plants, chemical, mining, food and fertilizer industries, coal preparation plants and many others.

Features:

• High availability and operational reliability is the result of a highly Developed design and quality Standard.
• Reasonably priced and flexible due to the use of standardize components.
• The machine is economically Equipped to customer's requirements with screen decks made of spring steel wire perforated sheet wire Perforated sheet metal, rubber or polyurethane optimum utilization of the screening area by a deck arrangement which is adapted to suit the grain size concerned, namely longitudinal, transverse, inserted and laid linings.
• Quick changing of screen mats and of the specially developed removable names, to allow lengthwise tensioning using simple screw connections.
• Low noise level with grease lubricated circular drive units which run extremely quiet and are of a stable design with low harmonic oscillation
• Generously dimensioned Bearings give long service life
• Low maintenance costs resulting from a direct drive using a normal commercial motor and a maintenance free cardan shaft.
• Dust seals are available as a options for all screens
• Easy, quick installation and removable of worn and replacement parts by the use of screw connections.
