We all know how to use the equipment correctly, which can effectively improve its work efficiency and prolong its usage time. However, how to operate the coal washing equipment correctly? Next, let's follow the coal washing machine manufacturer - Jiaozuo Shenzhou Coal Washing Machine Manufacturing Co., Ltd. to learn more.

　　1. Startup sequence: When water flows out from the inlet of the coal washing machine, start the water pump first. Open the grading belt, dewatering screen, and lifting bucket (123, then open the air valve, and then open the fan and final coal screen) to feed the conveyor belt.

　　2. Shutdown sequence: Under normal circumstances, stop the feeding belt conveyor and final coal screen first, and then stop the water pump, fan, and air valve. Stop the machine when there is no material in the lifting bucket, dewatering and grading screen, and belt conveyor to prevent accidents from occurring when restarting.

　　3 Lubrication: Apply butter to the head of the hoist and the vibration motor once a month. Apply butter to the oil injection holes of each reducer, fan, and air valve once per shift. The first oil change time is one month, the second time is every three months; In the future, change the oil every six months. When injecting oil, pay attention to the flashing of the oil mark and oil window to prevent excessive or insufficient addition.

　　4. Operation: Each gate should increase or decrease the number of discharge times. If the gangue content exceeds 20%, depending on the type of coal. If there is no material in the lifting bucket, it must be discharged. The principle is to discharge frequently and place less. The head of the lifting machine is equipped with a safety pin, which will not disconnect under normal circumstances. If the lifting amount is exceeded, it may disconnect. After installing the safety pin from the beginning, it is necessary to test the machine from the beginning to check for any jamming. If any, it should be eliminated before production can begin.

　　5. Adjustment: Adjust each coal slurry valve (air valve) and stop valve (water valve). The normal order is to open the first air valve and water valve from the feeding port, according to the size of the coal type and material quantity. Decreasing in sequence.

　　6. Sorting the bed: Remove the iron and debris at the bottom of the sieve, and tidy it up every 10 days. Make each ventilation hole have good ventilation function. Regularly check the bolts in various parts to see if there is any looseness, and if there is, tighten them.

　　When operating the coal washing machine, summarize the operation of the coal washing machine based on the above six points. It is essential to pay attention to the order of its operations in order to ensure a smooth and safe completion of the work.
