Keep Rock Crusher in Good Condition

1.Keep close to the working situation of the rock crusher.

As it is, you never realize how important something is until you do not have it, or when it is most required. In order to skirt high repair costs and production loss, proper periodical maintenance of rock crushers is required. The most logical thing to do in order to maximize the crusher life is to establish and execute a plan that will increase the life of the crusher thereby reducing repair cost and increasing the output. This can be done through laying down a rock crusher maintenance schedule that is adhered to. Following are five steps to help achieve the goal.

2. Know and follow the Rock Jaw Crusher Constraints

Every machine has a few reservations and this applies to a rock crusher as well. There are basically three limitations that are particularly important to be kept in mind while operating a crusher i.e. the horsepower, volume, and the crushing force. It is an overload if any one of these limitations is exceeded during operation. The operator needs to take into consideration the type of rock being crushed and environmental conditions as this too may change the rock crusher’s limits on the fly. By forcing the crusher to go beyond limits and stressing out different aspects of the machine, the lifespan is decreased and the time that it has between repairs and failure is shortened. All this leads to more repair expenditure, more man-hours, reduced output and in few cases permanent failure of the machine.

3. Familiarize yourself with the Maintenance Needs of your Rock Crusher

As with all the mechanical machines, maintenance is needed and must be followed. Rock Crushers are no different. There are three types of maintenance that one must follow to properly maintain the crusher. They are – Preventive maintenance, Predictive maintenance and Reactive maintenance. sand making machine:

A.Preventive Maintenance

This type of crusher maintenance plan need to be on a schedule and followed to keep up the crusher life. Following the manufacturer’s maintenance manual should be the rule in this case. This includes looking after the components like crusher liners and other wearing components for their good health.

By not changing the liners in the crusher as they become less and less efficient, you will not only be losing money because of poor/out of spec product but also on labor as well since the operator will still be there for the same amount of time, but doing much less crushing. Also, the out of spec or oversized material may re-circulate in a closed circuit to further increase the load on the already deficient crusher.

B. Predictive Maintenance

This refers to monitoring the condition of the rock crusher while it is in use. This is done by using predictive maintenance tools, such as lubricating oil thermometers, lube oil pressure gauges, lubricating oil filter condition indicator device, lube oil analysis, crusher drive motor ammeter and daily operator crusher log sheets. These are used to determine the normal operating specs of the crusher. This will allow seeing when things are not running properly and allow proper and corrective action to occur.

C. Reactive Maintenance

This maintenance occurs when the crusher is not operating properly and it is decided it is time to fix. In other words, waiting until it is broken in order to maintain it. This should be seen as the last resort and be avoided.

As the professional manufacturer of complete sets of mining machinery, such as aggregate jaw crusher, Henan Hongxing is always doing the best in products and service.
