Poor Screening Quality of Dewatering Screen? No Discharge or Slow Material Movement? 3 Quick Solutions

Poor screening quality, no discharge or slow material movement of dewatering screens are mostly related to equipment parameters, material conditions and component wear. The problems can be checked and solved in the following steps:

First, adjust vibration parameters and angle. If materials accumulate and fail to discharge, check the angle of the eccentric block of the vibration motor and appropriately increase the angle to enhance the vibration force; if the material movement is too slow, slightly adjust the inclination angle of the screen box (usually controlled between 15°-20°), and at the same time ensure the correct rotation direction of the motor (dual motors need to rotate in opposite directions) to avoid vibration force cancellation.

Second, optimize material pretreatment and feeding. If the incoming material contains large impurities, install a impurity removal device at the front end; if the material has high water content leading to agglomeration, appropriately reduce the feeding amount or add a dispersing device at the feed inlet to prevent materials from agglomerating and blocking the screen mesh.

Finally, check vulnerable components and screen mesh status. Damaged screen mesh will lead to reduced screening quality and needs to be replaced in time; if the screen mesh tension is insufficient, adjust the tension bolts; at the same time, check whether the springs are aged and invalid, as invalid springs will weaken the vibration effect and need to be replaced and maintained regularly.

Through the above three steps, the common operation problems of dewatering screens can be solved efficiently, and the screening efficiency and quality can be restored.
