Requirements on oil for lubrication of mining crushers

In the operation of a cone crusher, it will generate friction between the mutual contact surfaces and surfaces with relative motion, it consume energy for overcoming the friction, which will reduce the efficiency of the crusher. The friction power will be converted to heat, which is adverse to the machine movement and friction is one of the root causes of the parts wear. It is proved the most effective method to improve the part’s surface friction of the crusher is to the reasonable lubrication of a crusher, so as to improve the efficiency of machines and extending the service life of parts and to ensure that the machines work.

With the further improving of the mechanized degree of a crusher, the requirements on the quality of the equipments are higher and higher. In order to realize the reliable operation of the equipment, improve performance, reduce the friction power loss, reduce the temperature rise and reduce wear and lubricant consumption, reasonable lubrication technology should be used to achieve continuous and reliable operation of equipment. What”s more, rigorous testing must be indicator of quality of the oil, only to ensure the reasonable lubrication of various parts of the equipment, can the normal operation of the machine be ensured and to extend the life of the machine.

Lubrication is to reduce friction by adding some material between the friction surface and the material. The lubricant used in the machine includes four major categories gas, liquid, semi-liquid (semi-solid) and solid. Among which the fluid lubrication (mainly include oil lubricant) is the most widely used because the carrying capacity of the gas lubrication is much lower and the structure is complicated, solid and semi-solid is without cooling and flushing effect.
