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

Screen's inclination normally varies between 15" to 25 ; and can be installed with fixed angle or adjustable bracket arrangement. Speed of screen varies between 850 R.RM. to 1150 R.PM. depending upon the"G" value desired.

Screens are manufactured in following widths 800, 1000, 1200, 1400, 1600. 1800, 2000. 2200 m.rr and lengths varying from 1500 m.m. to 6000 m.m. Number of decks, can be upto four. Maximum dec area : 14 sq.m.

VIBRATOR UNIT

The vibrator Unit is a steel shaft, completely housed in a protective steel tubular casing which in turn is provided with an easily replaceable rubber cover to resist damage and abrasion. Balance Weights are keyed to shaft.

The bearings are specially designed for the use on screens and are a high capacity self aligning doubl roller type. These bearings have special tolerances and improved lubrication facilities to give extende< bearing life under their ardous working conditions. Labyrinth type grease sealings are provided to prever dust getting into bearings. A deep groove V-belt Pully is bored eccentrically to ensure true running arn to obviate the belt whip.

SUPPORTING COIL SPRINGS :

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.

SIDE STRETCHING DEVICE :

For maintaining correct tension, side stretching arrangement is provided for the screen cloth. Thouc for the screens with hood it is a common practice to use longitudinal stretching it is essential to keep tr screen deck always in tension.

SELECTION OF SCREENING MACHINE :

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. And therefore it is imperative to fill in the questionnaire give by us, to enable us to recommend you an appropriate screening machine.

SPECIAL PURPOSE SCREENS :

We also manufacture elliptical-motion screens, dewatering screens, drying screens etc. Normally these screens are horizontal & may have inclination upto 5 ° .
