1. Hoist: First open the crusher and then the hoist, or feed too much at one time, Fly Ash Vertical Mill causing the hoist to fail to start or suddenly overload and stop. If the machine is blocked, the small doors on both sides of the hoist should be opened, and the material should be allowed to start again after the material is exhausted. 2. Main machine: The material in the main machine is shut down and goes to work without being worn out. Causes the next host to start at full load and easily overload the motor. 3. Fan: The large inlet valve is not closed before the fan is turned on. Hazardous: Overheating the motor. 4, electric control cabinet knife switch: not in place, because the contact surface is too small, the resistance is large, it is easy to heat the wire. The requirements must be in place. Take a hard shot when closing, and open the electric control cabinet door to check whether the three switch pieces are locked in place. If they are not in place, knock them in place with insulators.

5. Electromagnetic vibration feeder controller: The control knob is not reset to zero before turning off the power (that is, the starting point of rotation), or it is quickly adjusted to the maximum before power on, causing the thyristor controller to burn out. 6, the large cyclone collector under the control valve: think it is the cause of the unsatisfactory blanking, and bundle it to make it fully open. Harmfulness: (1) The collection efficiency is extremely reduced, a large amount of dust-containing air flows back to the fan, and the fan impeller and fan casing wear quickly. (2) Low output. (3) Because the intake air volume is too large, and the residual air pipe cannot be completely discharged, a large amount of dust is sprayed into the main machine inlet.
