What are the common problems of single cylinder hydraulic cone crusher

 The single cylinder hydraulic cone crusher is highly valued by many ore processing enterprises for its efficient crushing . So what problems do single-cylinder hydraulic cone crushers generally face in the face of different equipment use environments? What should we do when facing these problems?

1. The problem of tightening and loosening of the upper cover and the lower cover.

After the upper and lower shells of the crusher are closely matched by steps, they are connected by 20 M 42 bolts, but the bolts loose and break during the operation. To this end, the following measures have been taken:

Design the base as an elastic mechanism to buffer the crushing force inside the equipment; use a torque wrench to ensure that each M42 bolt must reach a tightening torque of 3640N·m; by padding or repairing the connecting steps between the upper and lower housings To ensure that the gap between the two is within 0.25mm.

2. Dust problem.

Due to the external environment, the external fan of the dustproof system of the crusher is seriously clogged with the filter element, and the wind force cannot be directly observed. The wind pressure is often caused by the failure to replace the filter element in time, the dustproof effect is poor, and the oil is frequently replaced. If the filter element is replaced regularly, it will cause unnecessary waste. To this end, it is planned to add a pressure control valve on the dust-proof air outlet in order to replace the filter element in time and effectively control the air pressure.

3. Cooling problem.

For example, the lubrication system of two crushers in a factory is in a narrow space about 2m below the ground level, and the poor ventilation has a impact on the air cooling system. Due to the lack of air circulation, although additional cooling facilities such as fans and ice cubes were added, the air cooling effect was still not , so the protection temperature had to be increased, which was very detrimental to the crusher. To completely solve the problem, we can only proceed from the aspects of cooling fan displacement, lubrication system civil engineering transformation and cooling method transformation.

4. The problem of ore outlet adjustment.

In the early stage of the replacement of the new lining board, the ore outlet can reach the set value of about 13m; but after the lining board is worn to a certain extent, the ore outlet is expanded to about 18mm and cannot be adjusted downwards; The ore discharge opening reaches about 20mm, and basically does not have a crushing effect. For this reason, measures were taken to adjust the eccentricity from the original 50mm to 40mm. After adopting this measure, although the throughput of the crusher has been reduced, it can basically keep the discharge port at about 13mm, which is beneficial to increase the qualified particle size in the discharge and reduce the return to the mine.
