Grinding, the final stage used in the comminution process, is usually conducted in cylindrical tumbling mills where the particle size is reduced through a combination of impact and abrasion. The primary differences between these mills are in the ratio of diameter to the length of the cylinder and the type of grinding media employed. Grinding media can be steel rods, steel balls, hard pebbles or the ore itself.Because of friction on the surface,by a lot of pressure,so the lubrication for the crusher has a great significance. Commonly lubricants oil at station. Winter 20 or 30 lubricating oil. General mechanical oil can be used at the temperature of 40-50 can be used in summer. In Winter ,the alpine region use #10 or #15 lubricating oil, to meet the work and the circulation pump properly.This series of cone crushers are used for crushing ores and rocks, and the advantagesare: reliable structure, high efficiency, easy-to-adjust and economical. There is Spring cone crusher, Symons cone crusher. The safety spring system is the overload protection device, which makes foreign material goes through the machine without bring any hurt to it. The sealing modes are oil and water, which segregate the stone powder and lubricating system. The crushing chamber is decided by the purpose of ore, the standard model is suitable for medium crushing; the medium model is suitable for fine crushing and the short head model is suitable for fine crushing.In winter we use low lubricants oil,oil is thinner, in the case of low temperature, liquid can guarantee , if you use high-oil lubricants, oil more viscous, liquidity is not good, if the room is not heating and thermal device, the pump station can not work. In summer we need high #oil,,because the indoor temperature is high, so thick oil become thin, we ensure the liquidity of the oil. No. If you use lower oil in summer, that’s not ideal lubrication, oil lubrication point appear on the film has not formed and flow out of the phenomenon....
