Sand dryer is an industrial equipment used to reduce the moisture content of sand and improve its use value. It heats the wet sand in a rotating cylinder to evaporate the moisture through the principle of heat exchange. The equipment has a compact structure, easy operation and high energy efficiency. It is widely used in construction, casting and other industries to improve the quality and stability of sand.
Sand dryer fault diagnosis.
1. The raw material cannot be dried. Check whether the size of the dryer is appropriate, whether the heating system is normal, whether the wind pressure and air volume are sufficient, and at the same time confirm whether the material feed is too large. If necessary, adjust the sand dryer equipment parameters or increase the heat source power.
2. Equipment overheating. Observe and detect whether the heat source system, ventilation and heat dissipation system are normal, whether the temperature control device is accurate, and clean up the dust in time to ensure effective heat transfer and discharge.
3. Transmission system failure. Regularly check the wear and lubrication of transmission parts such as bearings, chains, belts, etc. If there is abnormal sound, heat or damage, replace and repair them in time.
Preventive maintenance measures for sand dryers.
1. Regular maintenance. Perform routine maintenance on the sand dryer as planned, including cleaning up the accumulated materials, checking the fasteners, lubricating the moving parts, replacing the worn parts, etc.
2. Inspection and repair. Regularly inspect the key components such as the hot air furnace, dryer body, conveyor belt, fan, etc., and repair them immediately if any problems are found.
3. Lubrication management. Lubricate strictly according to the equipment manual to ensure that all bearings, gears and other parts are fully lubricated to reduce wear.
