During the use of vibrating screen, the particle size of sieve material particle size is different, the accuracy and requirement of material are different, the capacity is also different, thus the relation between sieve surface inclination and capacity is inseparable,as well as the screening efficiency. Now PK Machinery will explain the relation as follows:
The angle is closely related with the sieving equipment capacity and the screening efficiency. When the angle increases,the casting strength of the oversize material will increase, thus the forward movement speed of material on the screen surface will quicken, meanwhile the capacity of vibrating screen increases, however, the time of the material staying on the screen surface will be shortened, reducing the probability of particles going through sieve, thus screening efficiency will reduce.
On the contrary,the capacity will be reduced,and the screening efficiency will be increased. In order to make the sieve screening efficiency ti be controlled in the ideal scope, the screen surface angle of circular vibrating screen generally ranges from 15 to 25 degrees, the sieve surface angle of linear vibrating sieve ranges from 0 to 8 degrees.
