Crushing machine is the most widely used equipment in the mining industry, and it is divided into several types according to different applications. the cone crusher is one of the most common ones and often used as the secondary crushing machine in the whole stone crushing process.
During the operation of the cone crusher, the operator often encounters a variety of problems. this article will list the common problems of the cone crusher and our professional engineers will give the most appropriate solutions, hoping it can help you.
To ensure good contact between the new bush and the spindle, the load should be gradually added after changing the bush to avoid burning the copper bush.
Poor oil quality will reduce the viscosity of the oil film, causing the oil film to rupture in the process of breaking the spindle bushing, causing the copper sleeve to burn out. therefore, it should be checked and replaced in time.
When the oil tubing is blocked or the oil pump39s capacity is reduced, it is easy to cause the copper bush to be oil-free and the oil film cannot be formed until the copper sleeve is burnt. therefore, the pipeline and the oil pump should be inspected regularly to ensure sufficient oil.
If the materials are mixed with iron, iron will increase the instantaneous load of the crusher, causing the oil film to rupture and burning the copper bush. therefore, the metal detector on the feeding machine should maintain a sensitive and reliable state.
The gap between the spindle and its bushing should be kept between 1.0 and 1.2 mm. if it is too large or too small, the copper bushing will be burnt. therefore, the gap between the spindle bushing and the spindle should be carefully checked during the replacement of new bushings.
The deformation of the spindle will cause a significant reduction in the cooperation between the spindle and the spindle bushing, especially after the crusher is running hot, causing the copper sleeve to burn. therefore, the spindle status needs to be checked regularly.
Generally, the gap between the locking ring and the adjusting ring of the newly installed crusher is 12.5 mm. therefore, according to the wear condition of the adjusting ring and the locking ring thread, the gap between the two can be appropriately increased to increase the locking force.
Different types of cone crushers have different maximum feeding sizes. once the size of materials exceeds the maximum feeding range, the crushing load will increase and the locking force will be relatively insufficient, causing the adjustment ring to vibrate and adversely affect the product size. therefore, the feed size needs to be strictly controlled.
