How can you prevent wear and tear of mineral crushers?

You can consider the following measures: A)Regular maintenance: 2)Proper lubrication 3)Correct feeding 4)Use high-quality materials: 5)Implement safety measures

To prevent exaggerated wear and tear on crushers the first point would be understanding the characteristics of the ore that you want to crush. This in-depth understanding of ore would help and allow the choosing of the correct crusher types but also it will inform in pit fragmentation parameters and blast design which would further aid keeping wear and tear to a minimum.

There are several ways to prevent the wear and deterioration of mineral crushers. Some suggestions include: - Perform preventive maintenance regularly, including checking and replacing worn parts. - Use suitable lubricants to reduce friction and wear of moving parts. - Control the feed speed of the material to avoid overloads and damage to the crushers. - Select the correct type of crusher for the type of mineral that will be processed. - Regularly monitor the performance of shredders to identify possible problems before they become critical.

Monitoring and adjusting crusher and plant settings is of utter importance, simply because ore feed tends to vary over time and thus the settings should be tweaked to match this.

In addition to those already mentioned, the following variables should also be monitored when operating a crusher: - Lubrication pressure ; - Different hydraulic pressures ; - The temperature of the lubricating oil at the crusher inlet and outlet ; - The temperature of the hydraulic oil at the crusher inlet and outlet; - The temperature of the electric motor.

1) Material fed to the crusher should be uniform and equally distributed. 2) Can be used stone box before entering into Crusher to reduce the impact and erosion level.

I believe , along with regular maintenance, you need to maintain feed at crusher by having proper fragmentation of rock blasted If your fragmentation is good, crusher would perform better

- A cone crusher fitted with a level sensor interlocked with the feed conveyor will keep the crusher feed cavity full ; - To ensure a quality feed at the start of the process, the Primary Crusher can be used to remove materials contaminated with clay, mud or even sand. - Dimension the Drill and Blast to obtain the following results: Rock sizes smaller than the primary crusher opening and low fines content in the blasted rock pile.

It is common practice to ensure that inspections are carried out on a shift per shift basis on the equipment these are visual inspections. Historic data should be kept thus informing when it is most likely that crusher performance starts to degenerate this will also help in planning maintenance strategies as well as informing the overall mine yearly shutdown plan.

- Normal wear and tear on the equipment will cause many problems for the operator. Leaking oil lines, loose drive belts, worn air clutches slipping, leaking air valves, these things all add up to more work and slower production. It is this type of problem that justifies the necessity of the operators circuit check. - As the Crusher Concave Liners and Mantle Wear out there is a period when the crusher won’t be as efficient as it could be. Since the throughput drops and operators have to work harder, usually doing the same thing over and over again. Unfortunately to get the most from the equipment requires that there is one hundred percent wear on the parts before they are replaced.

Below are some other important points to consider in ensuring reduced wear and tear to crushers: - Use the correct type of lubrication. - Maintaining & Monitoring the Feeding and conveyor systems. - Properly maintain V-belts, drives and motors. - Train operators - about 10% of wear is due to improper training of operators.
