Maintenance of Cylindrical Primary Screens

In the grain processing and storage industry, cylindrical primary screens are crucial for ensuring grain quality. Proper maintenance not only extends equipment life but also guarantees screening efficiency and grain processing quality.

Basic Maintenance

Standard Cleaning Procedures

Thoroughly remove residual grain and impurities from the screen mesh and equipment surface to prevent buildup that could affect future use. Use a soft-bristled brush to gently clean the screen mesh, preventing screen hole blockages. Wipe the equipment surface with a clean cloth to keep it tidy. Also, clear any spilled grain around the equipment to maintain a clean working environment and reduce the risk of pests and bacteria.

Key Points for Visual Inspection and Hidden Trouble Detection

Develop a habit of regularly checking the equipment's appearance for scratches, dents, or signs of corrosion. Pay special attention to whether connecting parts are loose, and repair any issues immediately. For example, if slight corrosion is found on the edge of the screen mesh, clean it promptly and apply protective oil to prevent further corrosion.

Maintenance of Key Components

Screen Mesh Maintenance and Replacement Timing

The screen mesh is a core component of the cylindrical primary screen, and its maintenance is crucial. In addition to daily cleaning, regularly inspect the wear and tension of the screen mesh. If severe local wear or deformation is detected, replace the mesh promptly to avoid affecting screening results. Generally, when wear causes screen hole size deviations beyond the allowable range, or when large-scale mesh breakage occurs, it's time to replace the screen mesh.

Lubrication and Tightening of Bearings and Drive Systems

Bearings and drive systems are the power sources of the equipment. Regularly lubricate the bearings to maintain good lubrication, reducing friction and wear. Also, check the tension of the drive belt; if it's too loose, it will slip and reduce transmission efficiency, while if it's too tight, it will accelerate belt wear. Timely adjustments to the belt tension and lubrication of the bearings can effectively ensure stable equipment operation.
