1.Reduce until the "over-iron" is eliminated: mobilize the enthusiasm of the workers, find non-crushed materials in time, and try to avoid entering the cone. A double-tube iron can be placed in front of the metal detector to remove the smaller iron to reduce the burden of the iron-removing trolley and reduce the failure rate.

2.Strengthen the training of technicians, maintenance fitters and operators to improve their quality and eliminate problems caused by human factors.

3.Strictly follow the maintenance procedures to improve assembly accuracy and maintenance quality.

4.Replace with nylon bushings. Nylon bushings have the advantages of light weight, fatigue resistance, creep resistance, wear resistance and corrosion resistance. More importantly, its impact resistance is good, the price is cheap, only 1/3 of the copper bushing, and the life is 2-3 times of the copper taper sleeve.

5.Strengthen the management of equipment, it is recommended to develop maintenance plans for major equipment such as cone crushers, and replace the parts that meet the scrapping standards or need to be repaired in time to eliminate the phenomenon of assembling equipment.

6.Strengthen the management of the lubrication system: 1 Strengthen the treatment of dust, strictly prevent entering the lubrication system, strictly prohibit driving in the state without dustproof water, and at the same time reform the water seal, add a layer on the oil retaining edge of the bowl-shaped tile seat Felt dust; 2 strictly prevent three water (dust, cooling water, sanitary water) into the lubricating oil; 3 strengthen the management of the thin oil station, the sealing should be strict, the filter should be replaced frequently; 4 eliminate the unclean assembly Contamination of the lubrication system; 5 transformation of the oil return section, installation of a filter drain device, and regular discharge.

7.Balanced feed: Try to drive when the mine is full.
