Excessively fast feeding speed or oversized materials
When materials are fed too quickly, the machine cannot process them in a timely manner, leading to clogging. This makes it extremely difficult for the screen to filter the materials, resulting in machine vibration and unstable operation. Over time, the screen cannot withstand such constant pressure and eventually cracks. Therefore, during feeding, two key points must be followed: first, control the size of the input materials; second, regulate the feeding speed. Only by combining these two measures to ensure stable operation can screen fracture be effectively prevented.

Excessively long screen size causing loose tensioning bolts
Mismatch between the tension plate and the screening unit of the forced-feed wood crusher, or wear-thinning/deformation of the tension plate (hook), can lead to this issue. To resolve it, first remove the screen, then reduce its size through cutting and welding, ensuring that the screen perfectly matches the structural design of the screening unit.

Entry of hard materials such as metals and stones into the machine
Hard foreign materials can easily damage vulnerable parts like the screen. never mix metals, stones or other hard materials into the feedstock to ensure the stable and efficient operation of the equipment.

Solutions to Screen Fracture of Forced – Feed Wood Crushers
Time:2026-01-23
The wood crusher represents an upgraded version of crushing equipment. Based on the original wood crusher, this device is equipped with an automatic feeding unit. It uses high-strength magnetic rollers to extrude and slice materials, which are then conveyed to the crushing chamber and pulverized by means of hammer blade impact. Qualified crushed materials are discharged out of the machine through the screen. However, what causes the fracture of the screen—the key component that determines the size of discharged particles? And how can we address this problem?
