Four Reasons and Four Solutions about Vibrating Screen

Vibrating screen is one new type screening machine with multi-function and high-efficiency features. It is widely used for mining, building material, transportation, energy, chemical and other industries and it is the ideal equipment for screening process. Of course, sometimes vibrating screen also breaks down. Next, let's make shallow analysis on the abnormal phenomenon.

Reasons why vibrating screen can't be started normally and solutions.

1) Broken electric motor; to change the electric motor.

2) Insufficient voltage; to change the power supply.

3) Too many materials on screening surface; to clean up the materials.

4) Wrong with vibrator; to check and repair the vibrator.

Reasons why material transportation is abnormal and solutions.

1) Incorrect vertical screen box; to adjust the height.

2) Broken supporting spring; to adjust the spring.

3) Damaged screening surface; to adjust the screening surface.

4) Uneven material feeding; to operate evenly and steady material feeding.

Reasons why screening quality is not excellent and solutions.

1) Blocked screen hole; to reduce the load on vibrating screen and clean up the screening surface.

2) Increasing moisture of material in the screening machine; to change the inclination angle of screen box.

3) Uneven material feeding; to adjust the material feeding.

4) Too thick feeding layer of screening surface; to reduce material feeding of screening machine.

5)Loose screen grid and conveyor belt; to tense screen grid and the belt.

Reasons why vibrating screen rotates slowly and bearings turn hot when it is working usually and solutions.

1) Lack of lubrication oil for bearings; to add up usual lubrication oil into bearings.

2) Blocked bearings; to clean up bearings and change the lock ring.

3) Too much lubrication oil and improper oil; to check lubrication oil for bearings.
