GuiLin HangDa Mining Machinery Co.,LTD. HD series ring roller mill must be started in strict accordance with the instructions. HD-1018 ring roller mill as an example, the specific operation steps are as follows:
(1) close the main power switch and the voltmeter indicates a voltage of about 380V.
(2) start the air compressor, adjust its working pressure to 0.5-0.65mpa, close the control power supply of pulse electromagnetic valve at the same time, open the air supply valve, can hear the dust collector from the interval of "touch", "touch", pulse jet sound, indicating that the dust collector into a normal working state.
Air compressor's working pressure is too high, easy to damage the cloth bag, dust removal effect decreased;
The pressure is too low to reach the ash effect.
The pulse controller has been adjusted before delivery, and is generally not allowed to be adjusted unless the production is abnormal.
(3) start the star discharge valve switch of the cyclone precipitator and pulse precipitator.
(4) start the elevator.
(5) start the crusher, after the completion of starting can be added to the material crushing, so that the hopper has a certain material reserve.
(6) start the analysis electromechanical machine. The motor adopts frequency conversion governor to adjust speed. Press the operation key of the frequency converter first.
(7) close the inlet valve of the fan, start the blower motor (Y- delta start), open the inlet valve after the completion of starting.
Sometimes, in order to remove residual materials in the system, after the fan runs normally, the valve is deliberately opened and closed several times when the damper is opened;
The outer cone wall and pipe connection of the cyclone collector and the pulse precipitator are struck with a wooden hammer to remove the residual materials in the system. At this time, the excluded materials are unqualified materials and should be sent back to the storage hopper to the main machine for crushing.
Clear and then close the damper to the desired air volume position.
(8) starting the main mill (Y- delta start), in order to make the grinding roll, grinding ring but more wear and avoid the ring mill vibration too large, the host idling time should not be too long that is not more than 2 minutes.
In order not to make the main engine start load is too large, when starting the main mill is not allowed to have too much material.
(9) start the electromagnetic vibration feeder and adjust the amplitude as required.
