Featuring the same expertise that has made Machinery Lubrication the standard for lubricant professionals around the world, Machinery Lubrication India is now being offered for Indian readers. The new magazine will include articles from international experts as well as local content and news contributed by Indian authors from industry and academia.

In practical mining production, we often have the problems of quick-wear parts. It affects equipment performance and production efficiency. It is a regularly work for mining machines maintenance. Should we really want to keep machines good condition, we have to learn daily repair at least.

At first, as we all know, we should protect machine from hitting or damage. Ensure clean of them and can not make machine contact with chemical things.

Besides, bearing is responsible for the whole operation load. It is important to prolong bearing service life. Good lubrication does much with operation efficiency, as well as bearing use life. Above of all, the pouring lubricating oil must be clean, and sealing is good.

The compound crusher is one of the most common equipment in crushing and sand making production line, while its motor is usually damaged; Hongxing machine experts holds view that there are many reasons lead to the damage of compound crusher motor; besides conventional failure cause of common motor power equipment, the running fault of compound crusher also can damage the motor, shown as follows:

1. The reliability and sensitivity of the automatic pressure switch; the starts and stops of compound crusher are normally controlled by the automatic pressure switch (pressure relay) directly driving alternating current contactor. The automatic pressure switch mostly adopts mechanical structure, which act on contact by the compress and release of spring. The congenital deficiencies or improper adjustment of automatic pressure switch can cause motor damage.

Second of all, we should reduce the temperature effect to machine. During operation, all the parts are running in their own normal temperature ranges. That is, general cooling water is between 80-90。C, while the temperature range of hydraulic system is 30-60。C. Both the lower and higher temperature can cause components wear and damage, lubricating oil becoming bad, and material performance weak and so on. Therefore, during in use, we should guarantee low speed normal operation at preheated stage, so as to reach the standard temperature for normal operation. In no case should the machine operates overloaded in lower temperature. Similarly, higher temperature operation should also be avoided. Operators should check values on the thermograph. If fault occurs, operator should stop the machine at once, check and solve the problems. As for the uncertain problems, we should not let it go and makeimpact crusher work with trouble. In daily work, the work condition of cooling system should be checked at times. As for water cooling machines, workers pay attention to adding cooling water. As for wind cooling machines, you had better to clean dust as regular intervals to ensure cooling air duct smooth. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery,
