What inspections do you need to do before the aluminum powder paste ball mill drive?

　　Aluminum powder paste ball mill as an important equipment in the mineral production, the operation of the aluminum powder paste ball mill needs to be particularly careful, whether the starting method of the aluminum powder grinding machine is correct, is the key to ensuring its normal operation, in order to ensure that the equipment can be smooth The operation increases production efficiency, reducing hazards, we should start the equipment in accordance with the correct operation method, the following Hengchang Machinery Technology Department technicians introduce the start of the aluminum powder grinding mill in detail from the preparatory, specific startup step and startup precautions. I hope to bring help, standard operation to the majority of users, to a large extension of the service life of the aluminum powder paste ball mill.First, the preparation before the aluminum powder paste ball is started

　　1, the aluminum powder paste ball mill should be carefully examined before the connection bolts are tightened, the gear, the coupling, and the mine or other The nipping of the bolt, check the gear and the gear and the gear;

　　2, the mill that has not been taken after the new installation or maintenance, it must be rotated 2-3 turn before starting, Check if the mill is collided with other machines;

　　3, check whether the oil volume meets the production needs and timely supplementation, the quality and quantity of the slag pump lubricants meet the production needs, timely replacement Or replenish the lubricating oil;

　　4, check if various protective devices such as oil-oil protection parking, hydrocomputer, oil pressure cutting appliances, and interlocking devices and audio signals, etc. are complete, reliable

　　5, check whether the instrument and protection device are good, the air pressure of the pneumatic clutch reaches the requirements;

　　Second, the start of the aluminum powder paster mill

　　1. Before starting, the production section associated with the work of the grinding unit is contacted, and the electrical examination of whether the insulation of the ball grinding motor is good, whether the excitation control cabinet test allows power to boot, and start the drive motor without fault, The automatic gear start motor is pressed and the start button; manually blocks the motor, press the start button, the motor begins to rotate, and press the run button when the motor speed reaches the rated speed. 2, the two-stage sand pump immediately started two aluminum powder paste ball mills, and then started a piece of sand pump and a paragraph of aluminum paste ball mill, opening water valve to a mill and slag tank water, millAir transfer 1-2 minutes, the standby group can start the aluminum powder grinding machine, and the size of the amount of the amount of the amount of feed is controlled to stabilize it, pay attention to the front and rear end cap, the cylinder is leaking, and the cylinder is leaking. The mill work conditions are adjusted in time according to the change of ore changes.

　　3, the level of liquid level in the slurry tank is a feeding that makes the pump can be normal and stable, and the air in the slurry has sufficient time to precipitate; observe the production of the cyclone Status, the normal production of the cyclone flag is from the exclusive umbrella, suitable umbrella angle is 20 ° ~ 30 °, which is greater than the angle, and its sand grain level is low and the fine grain level is high, and the grading efficiency Low, smaller than the angle, the thickness of the thick grain level in the high and overflow is much lower, and the grading efficiency is also low. Adjusting the amount of inexpress tonic to control the concentration of the cyclone in the range, so that the rotation fluor is working well.

　　Third, the aluminum powder paste ball mill startup precautions

　　1, the shoulder process cannot exceed the specified start with the abbreviated mill alkali pressure Time, start-up time is generally 15-20S If the start button grinder begins to rotate to the specified time grinder does not reach the rated speed, the start should be stopped immediately, otherwise the cell-sensitive varistor will burn. After stopping the launch, check the mechanical and electrical appliances carefully to find out the reason why the startup can't be started. Secondary startup and the time interval of the last time to be 15MIN. If the temperature of the cell-sensitive resistor is relatively high, it can be forced to cool.

　　2, the mill continuous start is not allowed to exceed twice, and the three startup must be performed after a comprehensive examination.
