The ore feeding of the cone crusher shall be uniform to prevent the overload caused by uneven feeding, which leads to the excessive negative simplicity of the fixed cone liner and the grinding deviation. Always check the discharge condition to prevent the materials from accumulating at the ore discharge outlet. Always check the pressure of oil pressure or spring safety device and adjust the ore discharge outlet in time. The operator shall regularly observe the movement temperature rise and vibration of all parts to prevent the loosening of connecting parts and foundation bolts. Check whether there is ore or other objects in the crushing chamber, and whether the oil pressure or spring safety foot is normal.
When the cone crusher operates, the hydraulic oil temperature shall meet the requirements specified by the equipment. The particle size of crushed materials shall meet the requirements of the product manual. The feeding shall pass through the distribution plate, and the feeding amount shall not be higher than the horizontal plane of the rolling mortar wall. The operating current and power shall not exceed 85% of the rated current and power. The equipment shall be regularly inspected, maintained and repaired. During the operation of the crusher, the pressure of the locking system and the working condition of the hydraulic station shall be checked. In case of oil leakage and insufficient locking force, the crusher shall be shut down for inspection and repair. After the crusher is installed, the no-load test shall be conducted for 7 ~ 8h. If there is no fault, conduct 12 ~ 16h on load test again. At this time, the oil temperature discharged from the oil drain pipe shall not exceed 50-60 ℃.
The ore in the crusher is unevenly distributed. It will cause eccentric wear of parts such as fixed umbrella plate and adjusting ring, resulting in unqualified products and reduced productivity. In serious cases, it will cause one side of the crusher to move, which will increase the support pressure of the spring and accelerate the wear of the matching slope between the support sleeve and the flange of the machine body. Therefore, before the ore enters the crusher, the screening device will be used to keep the fine powder materials and large block materials outside the crusher for treatment. So as to ensure that the particle size of the machine is relatively uniform and avoid the occurrence of the above accidents.
