Removal of common problems of stone removal machine

(A) The lower column contains more grain

If the lower column in the stone removal machine contains too much food, to deal with the air intake problem, the key check the air intake valve ruler, the screen is not blocked, the machine equipment of the air network is not wrong, and the reverse direction cyclone adjustment is moderate. When the balance state of the material on the screen is still problematic, the air intake volume of the stone reducer should be measured. If the total exhaust air volume is small, it is necessary to check whether there is ventilation in the air duct of the stone reducer, the working environment of the centrifugal fan, and the situation of the cloth dust collector.

(2) The actual effect of stone removal is weak

If the working quality of the stoner is weak, under normal circumstances, most of the problems are the balance of the sieve powder, and the hand in hand side by side with the sieve powder can not be made to rise smoothly on the ground.

When the actual effect of stone removal is weak, the screw cap can be used to carry out comprehensive ability test under the working environment of stone removal machine. The vibration sign is used to check whether the vibration amplitude and throw Angle on both sides of the material are feasible and symmetrical, and if there is a problem, it is adjusted.

If the amplitude size does not meet the requirements, the focus block of the two vibration motors should be symmetrically adjusted. If the vibration amplitude on both sides of the screen body is inconsistent, the focus block equipment of the two vibration motors should be checked whether it is symmetrical and moderate.

If the track of the screen body is irregular, when there is shaking at work, it should be mainly checked whether the center line of the two vibration motors is parallel, whether the focus block equipment is symmetrical, and whether the torsion spring of the support point is damaged or invalid.

Especially after the maintenance and disassembly of the vibration motor, it should focus on the symmetry of the block equipment and the center line of the motor.

(3) The working quality of the feeding device is not ideal

If there is no running material on the feeding door of the stone machine and the inlet is ventilated, the working pressure door should be checked whether it is intact, the posture is not convenient, and the stretching spring of the working pressure door is not intact.

If the working pressure door of the stone machine is damaged due to the impact of the material, it is generally mainly because the pressure of the working pressure door is too small in the ordinary operation process, the material column is not formed by the door, and the raw materials immediately break through the material door for a long time, so that the material door is damaged. Such a situation is generally caused by the torsion spring of the working pressure gate being too loose, ineffective or falling down. Under the premise of replacing the new feeding door, it is also necessary to check the torsion spring of the new working pressure door.

The feeding working pressure door is stuck, the posture fails, and the feeding door cannot be closed, which will also cause the working pressure door to be invalid.
