　　ZNRH-M grinding roller lubrication station is suitable for the lubrication of large and medium-sized vertical grinding rollers in the building materials industry. The oil station supplies oil to the grinding roller, and at the same time, the oil in the grinding roller is pumped back to the oil tank through the corresponding oil return pump to lubricate the grinding roller bearings. While reducing friction, a large amount of heat at the grinding roller is brought back to the fuel tank through the oil. The cooling filter device of the oil station also filters and cools the oil in the fuel tank.

Thin oil lubrication

　　 When the friction surface of the mechanical motion pair is in relative motion, because the surface directly contacts and generates frictional resistance, a part of the energy transferred by the machine is consumed by the friction and the surface heats up, and the parts are worn at the same time.

　　 Thin oil lubrication is to force the lubricating oil to the friction part of the machine to form a lubricating agent film that can withstand part or all of the load on the friction surface, and separate the friction surfaces of the two moving pairs to make the friction between the metal and the metal. It is converted into internal friction between oil film molecules with lower shear strength.

　　 Thin oil lubrication mainly plays the following important roles in the normal operation and maintenance of mechanical equipment: 1) reduce wear, 2) cool down, 3) wash and clean, 4) prevent corrosion, 5) save energy and reduce consumption.

　　 Thin oil lubrication is mainly used for the lubrication of reducers, dynamic and static pressure or sliding shoe bearings of mechanical equipment such as electric power, metallurgy, petrochemical, cement, etc.
