Operating rules for grinding miners

1.

Preparation before driving


1)

After the inspection, the equipment inspection system is qualified and accepted for delivery.


2) Remove debris from the equipment before driving, check whether the screws of each part are tight, check the head number of the spoon, the wear of the graded blades, and whether the belt conveyor and the feeder are good.


3) Check whether the oil pipe is unblocked, the oil volume of the reducer should reach the oil mark line, the oil quality should meet the quality requirements, and the lubrication tools should be complete.


4) Check that the rotating parts and safety facilities are secure and that the electrical parts are fault free.


5) Check the water, slurry pipeline is smooth, each site with or without drip phenomenon 'Check the bottom of the discharge chute wear, and clear the tank debris.


6) Parking for more than two hours. Before driving, the ball mill and classifier should be driven to loosen the consolidated ore and reduce the impact load when the equipment starts.


7 After the inspection is completed, after confirming that the equipment in this position is normal, you can take off the “checking and repairing cards”, notify the next process and the electrician duty room to send electricity, and prepare to drive.


2.   Open parking sequence and precautions


1 ) In the case of driving in the next process, you can drive in the following order:


Start the oil pump, wait until the oil returns to normal → ball mill → classifier → open the return sand valve water valve → discharge tank water valve → drop grader → normal open tape conveyor → feed machine.


2 ) Precautions      When starting the device, press the start button with one hand and the stop button on the other hand, and observe the position of the running part and the current meter pointer. The ear listening device runs sound. If abnormal conditions are found, stop the parking immediately and eliminate the fault before driving. .


3 ) Parking     

Stop the mine before stopping the inspection, return the sand to the classifier, then stop the classifier and lift the screw to a certain position. Add water to rinse the ore and steel balls in the mill, then stop and close the water valve. Place the access tray in the desired position.


4 ) After the machine is stopped, pull down the main switch and hang up the “maintenance card” to carry out maintenance work.


5 ) Stop without maintenance, and stop in the opposite direction of driving order.


3 , working in operation


1 ) Adjust the amount of water added and the amount of ore added after the equipment is started normally to ensure normal process operation conditions.


2 ) Check the bearing temperature and lubrication condition of each part on time, check whether the oil pressure oil temperature is normal, and prevent the oil from entering the slurry to influence the selection index.


3 ) Perform the technical operation card regulations, and regularly measure the ore concentration and graded overflow concentration of the mill. According to the nature of the ore and the size of the ore, the ore supply, grinding concentration and amount of sand returning of the grinding machine are adjusted in time to ensure that the graded overflow fineness meets the process requirements and creates favorable conditions for the sorting operation.


4 ) Regularly add steel balls according to the regulations of the technical operation card.


5 ) Observe the working condition of the equipment, record the voltage and current of the main motor regularly, and master the wear and tear of the equipment parts.


6 ) Check whether the screws of each part are loose and the equipment has vibration or abnormal sound. If the screw is loose or leaking, find the parking lock in time to prevent the ore from falling into the gear and the hollow bearing bush.


7 ) If there is no notice of power failure, you should pull the general opening of the five in time, close the water valve, and then drive after the call.


4. Work after parking


1 ) Do a good job in equipment and environmental sanitation.

2 ) Check the equipment in detail and do some minor repairs.
