What should you pay attention to when rotating the crusher?

After the crusher enters the normal crushing work, the following items must be observed and observed during operation:

(1) Check the operation, there should be no abnormal knocking sound inside the crusher. Special circumstances should be stopped immediately. The grain size of the ore should not be more than 0.8 times that of the ore supply. The lower part of the discharge chute and the broken cone should not be blocked by the ore. Otherwise, the ore will be lifted by the broken cone to enter the eccentric shaft, causing an accident;

(2) Pay attention to the operation of the oil pump, and always check the oil flow indicator, the oil temperature and the oil pressure indication. The temperature of the oil after passing through the cooler should not exceed 45-53 ° C, the return oil temperature should not be higher than 60 ° C, and the oil is supplied to the upper suspension device on time;

(3) Pay attention to check the tightness of the V-belt. Use the thumb to press the V-belt to measure the tension. If the pressure is not more than 1.5cm, the tension is appropriate (measured before driving or after parking). Check for cracks and pay attention to the triangle belt not to stick oil;

(4) It should be checked frequently whether the connecting pin between the beam, the middle frame and the base is loose and the gap is 15.0 mm along the circumference;

(5) Check the lining of each part for looseness, lack of and severe wear;

(6) a rigorous inspection to the mining situation, and to prevent the hammer, a top metal brazing material into the crushing chamber;
