Lubricating oil is well known as an oily lubricant, according to the source can be divided into: dynamic, vegetable oil; Oil; Synthetic lubricating oil three categories. Grease, which is commonly known as butter, belongs to a kind of petroleum lubricating oil, which is like a paste suitable for mechanical parts that are difficult to flow. Mine oil, like other products, is used for lubrication, cleaning, cooling, etc., of mining equipment.

Grinding equipment, crushing equipment, sand making equipment and other mechanical equipment are mostly open-air operations, or dust dust is more, if the use of grease lubrication, the first use is not convenient. Grease should be added at least 2-3 times. The lubricating oil only needs to be added 1-2 times a week. Secondly, maintenance is not convenient, because of the exposure of its refueling parts, dust dust will accumulate on the grease, it is difficult to remove, and the use of lubricating oil is because its refueling parts are less exposed, and the lubricating oil can play a certain cleaning role without frequent maintenance. Finally, the viscosity of grease is large, which can easily lead to a decrease in operating energy consumption, and the lubricating oil can reduce friction, protect the machinery, and play the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering.
