Four-roll crusher

The principle of operation and characteristics of four-roll crusher

Four-roll crusher consists of frame, belt feeder, upper and lower pairs of rollers andmotors. Upper swath right and bottom left are spring-loaded depreciation and away from the stationary rolls, skipping non crushable objects. Four-roll crusher is equipped with machinery for grinding of tires (one for each pair of rolls). The material to be crushed is fed into the hopper and then belt feeder-dispenser is applied directly to the upper pair of rolls.

The performance of the four-roll crushers depends on many factors of a technical nature, length and diameter of the rolls, the frequency of their rotation, homogeneity and raznijsmot of the incoming material, as well as the width of the exit slit. When determining the dimensions of the pieces coming in four-roll crusher material, you must consider the weight of the piece, friction, pressure rolls on the piece.

Four-roll crushers are more effective because they allow after every stage of crushing sieving to produce the finished product and to direct and guide the subsequent fragmentation of the only required material for this. The design of the four-roll crusher allows independent adjustment of the rolls of each crusher, subsequently covering both the adjustment process secondary and fine crushing. The overall degree of crushing on this machine reaches 7.Granulometric composition is controlled by changes of the distance between the rollers. If deemed necessary, wholemeal rolls and rolls fine grind can be used for crushing material in a single stage with great performance.

The advantages of the four-roll crushers can be referred as a small yield pereselenskogo material, because compressing it in the workspace occurs one time. Four-roll crusher is equipped with self feeders to ensure continuous and uniform throughout the length of the power supply.

These indicators and characteristics of four-roll crushers provide high performance, which is an important factor for all customers.
