Stable operation of the drum screen is crucial for grain quality and production efficiency. Here are specific solutions to common drum screen malfunctions to ensure efficient equipment operation.
Regularly clean the screen mesh using a soft-bristled brush, water, or compressed air to remove impurities. For stubborn blockages, remove the mesh for a thorough cleaning. Also, optimize grain pre-treatment by adding pre-cleaning devices such as magnetic separators or air separators to reduce impurities entering the screen mesh.
Regularly inspect the wear of the screen mesh and replace damaged meshes promptly. Choose high-quality mesh materials and select appropriate mesh sizes based on grain type and screening requirements to extend mesh life.
Check if the drum is securely installed and tighten the anchor bolts if necessary. Balance the drum and replace worn components if needed. Inspect drive components, checking if belts are loose or chains are worn, and replace or adjust them in a timely manner.
Reduce the feed rate of the drum screen to prevent excessive motor load. Clean the motor cooling fan or heat sink to ensure the cooling system operates normally.
Regularly inspect the wear of drive components and replace severely worn parts. Adjust the tension of belts and chains appropriately to ensure proper operation of the drive components.
Select suitable screen mesh hole sizes based on grain type and screening requirements to ensure smooth discharge. Design the discharge port shape and size reasonably, and add discharge aids such as vibrators or guide plates if necessary.
