Circular Motion inclined Vibrating Screen is a two bearing free floating Vibrating Screen which efficiently screens all moderately free flowing materials.

The circular throw action is derived from imbalance weights which are attached to the ends of the vibrator unit and transmit a uniform vibration to all screening surfaces and ensures that material travels over the screening surfaces at a constant rate. The amplitude or degree of vibration can be adjusted to suit a change of duty by adding or subtracting balance weight plates. Circular motion ensures rapid stratification at the feed end and produces an accurately size product in the shortest possible time.

Screen's inclination normally varies between 15 to 25. Speed of screen varies between 850 R.P.M. to 1150 R.P.M. depending upon the "G" Value desired.

Screens are manufactured in following widths : 800, 1000, 1200, 1500, 1800, 2000, 2200 m.m. and lengths varying from 1500 m.m. to 7000 m.m. Number of decks, can be up-to four.

The Vibrator Unit is a steel shaft, completely housed in a protective steel tubular casing. Balance Weights are keyed to shaft.

The bearings are specially designed for the use on screens and are a high capacity self aligning double roller type. These bearings have special tolerances and improved lubrication facilities to give extended bearing life under ardous working conditions. Labyrinth type grease sealings are provided to prevent dust getting into bearings.

Helical compression springs support the vibrating basket of the Vibrating Screen. They absorb all the working loads, without transmitting undesirable vibration to the supporting structure.

It is essential to keep the screen deck always in tension. For maintaining correct tension, side stretching arrangement is provided for the screen cloth.

Proper selection of screen size is very important. The size and type of screening machine to be used requires a very close scrutiny of the material to be screened, its screen analysis, moisture content, shape of particles, separation required etc.

• High specific screening capacity.
• Compact Design.
• Bolted construction.
• Easy interchangeability of screen cloths.
• Long working life.
• Tailor made to customer's needs.
