The air-cooled crusher uses a built-in air cooling system to remove heat during the crushing process, avoiding material denaturation and adhesion caused by high temperature in the crushing chamber. It is widely used in material crushing operations in fields such as food, plastics, and medicine. The operation of the equipment needs to control parameters such as speed and air volume based on the characteristics of the materials. The specific usage method is as follows:
1、 Preparation before use
1Equipment inspection
Check the appearance of the equipment and confirm that the body and crushing chamber shell are not damaged; Check that the air cooling system pipeline is unobstructed, and that the fan blades have no dust accumulation or deformation; Open the crushing chamber door to clean residual materials and impurities, check that the crushing blade group is firm, without looseness or excessive wear; Confirm that the power and control lines are connected properly, and that the switch function is intact.
2Material preparation
Preprocess materials according to the equipment adaptation range to remove metal impurities and large foreign objects; When the moisture content of the material is too high, dry it in advance to a suitable humidity; Stack the materials evenly near the feeding port to facilitate stable feeding in the future.
3Parameter Settings
Based on the characteristics of the material, set the crushing speed and air cooling volume through the control panel; When the equipment has a grading function, adjust the grading wheel speed synchronously to ensure that the parameters meet the expected crushing requirements.
2、 Startup operation process
1Start the auxiliary system
First, turn on the air cooling system. After the fan is running normally and the cooling air duct is ventilated smoothly, keep it running for 1-2 minutes to ensure the pre cooling of the crushing chamber; When the equipment is equipped with a dust removal device, it should be started synchronously to reduce dust dispersion.
2Start the host and feed the material
After confirming that the air cooling system is normal, start the crushing host and wait for the speed to stabilize without any abnormal noise before turning on the feeding device; Control the feeding speed to maintain uniformity and avoid excessive feeding that may cause blockage or high load in the crushing chamber.
3Initial effect confirmation
During the first 5-10 minutes after starting up, take samples to check the particle size and temperature of the crushed materials. If the particle size does not match, adjust the grading wheel or crushing speed slightly; If the material temperature is too high, increase the air cooling volume and enter normal operation after the parameters stabilize.
3、 Monitoring and adjustment during operation
1Real time parameter monitoring
Check the temperature of the crushing chamber and the current of the host every 20-30 minutes. If the temperature exceeds the limit, reduce the feeding speed or increase the air cooling volume; Suspend feeding when the current rises abnormally, and continue after it returns to normal.
2Abnormal situation handling
Stop the machine immediately if there is a sharp friction sound, shut down the main engine and air cooling system, check the crushing chamber, and troubleshoot; When the material adheres to the cavity wall and causes poor discharge, pause the feeding and turn on the air cooling system to cool down. After the material falls off, empty and clean it.
3Maintenance of crushing effect
Regularly take samples to check the particle size of materials, and clean the grading wheel or replace the worn blade group when it is uneven; Thermally sensitive materials require frequent temperature monitoring to avoid discoloration and deterioration caused by high temperatures.
4、 End operation steps
1Gradually shut down
After the feeding is completed, keep the main engine and air cooling system running idle for 2-3 minutes to discharge residual materials; First, turn off the crushing host, completely stop running, then turn off the air cooling system and dust removal device, and finally cut off the main power supply.
2Equipment cleaning and inspection
After cooling the crushing chamber to room temperature, open the chamber door to clean the residual materials, and use a soft bristled brush to clean the blade group and grading wheel; Check the wear of the blade group. Minor wear can be polished, and severe wear should be recorded and planned for replacement; Clean the equipment casing, inlet and outlet.
3Organizing operation records
Record the type of material, processing capacity, set parameters, as well as abnormal operation and handling methods for future reference and equipment maintenance.
