As the main facilities in crushing system, the good running of HP cone crusher is the key to ensure the smooth working of the entire beneficiation workshop production process.
There are some problems in the process:
(1) liner replacement is time-consuming
HP300 is medium broken equipment in the crushing system, in normal production, liner replacement cycle is generally for 23 d, major demolition include: demolition action, fixed cone lining, replacement action, fixed cone lining heating The moving cone liner, filling resin, assembly. According to disassembly standards, each replacement takes 4 ~ 5 h, influencing the normal working of next procedure.
(2) counterweight guard wearing is bad
Due to the viscosity of ore, HP300-grinder rib protection board ore accumulation is serious, exacerbating the counterweight guard wear and maintenance costs. During welding repair work, because of the narrow space, there are a lot of security risks.
(3) Maintenance working is large
If the trays HP4 cone crusher is impacted largely, it easily lead to fixed bolts cut off and sub-trays. During liner replacement cycle, due to wear and tear, it also the need for cutting ring repair welding, maintenance workload is large. As the professional manufacturer of complete sets of mining machinery, such as primary jaw crusher, HXJQ is always doing the best in products and service.
2 improvement initiatives
(1) re-default HP4 grinder trays, which reduce the impact of the ore on the distributor plate to prevent loose in the distributor plate. Dimensions trays at the same time to ensure wear resistance, protect cutting rings from less affected by wear and tear.
(2) Increase an additional counterweight shroud avoids the ore enters the shroud and the counterweight between the guard plate, and prevent the slag into the internal lubricating system of the counterweight.
(3) improved liner installation way
According to the HP300 grinder liner replacement cycle, adopting homemade oven heated liner instead of gas welding preheating, not only saves manpower and resources, but also avoid uneven heating of the gas welding and easy to damage the lining of the problem.
