Purpose of Rotary Vibrating Screen Eccentric Block Adjustment


Do you know the purpose of adjusting rotary vibrating screen eccentric block? Here PK Machinery will introduce as follows:
Adjust the upper and lower eccentric block phase angle is to change the material movement and residence time on the screen sieve cloth so as to make the screen machine adapts to the requirement of various materials separation status , such as material distribution, hourly output, screening efficiency, passing rate changes, in order to change the eccentric block angle to the best condition.
There are extra heavy weights on the side of upper and lower eccentric blocks ,the main function is to increase the output exciting force of rotary vibrating sieve, you can increase and reduce the exciting force according to the different screen deck numbers and different material proportion which will make the screen reach the best sieving effect.
