Analysis Of Abnormal Causes Of Fixed Cone Of South Africa Dolomite Crusher

After a week of observation and investigation, the hydraulic system hydraulic pressure is normally stable, and the South Africa Dolomite Crusher fixed cone assembly can be locked without rotation. The reasons for the abnormal rotation of the South Africa Dolomite Crusher fixed cone assembly are as follows:

1. When there is a leakage phenomenon in the hydraulic oil in the hydraulic system, the oil pressure will jump up and down, and the fixed crusher of the South Africa Dolomite Crusher will not rotate and rotate.

When the sealing components in the pipeline joints, various valves, sealing devices, etc. in the hydraulic system wear or fail, hydraulic oil leakage or internal leakage is likely to occur, the hydraulic pressure of the hydraulic system drops rapidly, and the hydraulic system’s pressure compensation system The gear oil pump is automatically started, the pressure is automatically increased, and the oil pressure rises rapidly. Therefore, the red number of the lock cylinder oil pressure gauge jumps up and down from 17.5 to 22.5 MPa, and the friction force (locking force) of the fixed crusher of the South Africa Dolomite Crusher is not normal. Within the scope. Therefore, the South Africa Dolomite Crusher fixed cone assembly cannot be locked and rotated.

2. When the oil temperature of the hydraulic system rises slowly, the oil pressure will gradually drop. When it is lower than 18.5 MPa, the fixed crusher assembly of the South Africa Dolomite Crusher cannot be locked and rotates.

Since the lubrication station of the cone crusher uses only one air-cooling system to reduce and control the oil temperature, since the equipment has been installed and put into production, there has been a problem of high temperature of the lubricating oil. Especially in summer, the temperature of the lubricating oil is difficult to control in the safe range. Inside, it was modified and an air-cooling system was added to reduce the oil temperature, but it was not ideal.

The concentrator is located in the southern part of China. During the period from 14:00 to 20:00, the ambient temperature of the workshop is higher than other periods. Since the hydraulic oil tank and the lubricating oil tank are only separated by one steel plate, the heat of the lubricating oil is quickly transmitted to the hydraulic oil, which causes the hydraulic oil temperature of the hydraulic system to rise and the oil pressure to drop. When the oil pressure drops to 18.5 MPa or less, the movement is moved. The crusher fixed cone assembly cannot be locked and rotated. The ambient temperature in the morning and evening shifts is relatively low, the hydraulic oil temperature of the hydraulic system is not high, and the oil pressure is relatively stable. The HP200 South Africa Dolomite Crusher fixed cone assembly can be locked without rotation.

3. When the hardness of the ore is obviously increased, the crushed ore needs more crushing force, and the crushed ore gives the reaction force of the fixed crusher assembly of the South Africa Dolomite Crusher even more, even if the hydraulic pressure of the hydraulic system of the cone crusher is stable, The pressure of the lock cylinder is not enough, and the fixed crusher of the South Africa Dolomite Crusher is difficult to overcome the reaction force. Therefore, the South Africa Dolomite Crusher fixed cone assembly rotates abnormally.

4. When the moving cone filter and the South Africa Dolomite Crusher fixed cone lining wear to the later stage, the shape of the crushing cavity changes. Even if the crushing force of the ore does not increase significantly, the component force of the reaction force in the horizontal circumferential direction increases significantly. It is also difficult for the South Africa Dolomite Crusher fixed cone assembly to overcome the reaction force. Therefore, the South Africa Dolomite Crusher fixed cone assembly rotates abnormally.

5. If the ore in the cone of the cone crusher is too much or the ore contains a large amount of mud and the size of the discharge port is adjusted too fine, the broken ore cannot be quickly discharged. This will also cause the South Africa Dolomite Crusher fixed cone assembly to increase in force and cannot be locked and rotated.
