MRN Pendulous Hanging Grinding Mill

MRN Pendulous Hanging Grinding Mill represents the most advanced grinding processing technology. The brand-new structural design not only lowers the operation and maintenance cost, but also does well in environmental protection and finished product quality. It is available when processing the non-combustible, non-explosive brittle minerals products like limestone, calcite and marble, etc. MRN Pendulum mill is widely used in mining, building, power plant and coating industries.

Technical Advantages

Thin oil lubricating grinding roller device, low maintenance cost

Grinding roller device of MRN pendulous hanging grinding mill adopts thin oil lubrication, which is a technology initiated domestically, and is maintenance-free and easy to operate. Thin oil lubrication is of oil bath lubrication, which is more convenient than grease lubrication since no need for frequent oil-adding, and it is of lower maintenance cost as well.

Efficient powder collector, prolonging service life of equipment

Between the powder classifier and the powder collector, square pipeline is applied, which is convenient for multiple choices of wear-proof materials, and at the same time, it could avoid windage phenomenon in the entrance of powder collector due to variable diameter of the square and the circular pipeline.

Pulse dust collector, high efficient and environmental friendly

MRN pendulous hanging grinding mill applies pulse dust collector, removing ash via pneumatic force and operating automatically, which omits manual ash-removing operation and completely eradicate powder pollution. The whole process is of excellent environmental protection effect.

Configuration science, reduced energy consumption

New hanging type cage sorter, variable frequency control, fine controllable finished product; isolated cyclone powder collector, high efficiency of collecting powder; curved air duct, small airflow resistance

Working principle

As for the working process of each main unit, the roller part is the key in pulverization. By rotating, the materials can be ground into powder with ideal and expected size. The rollers of MRN Pendulum Mill take thin oil lubricating device which operates automatically. It works with rollers synchronously to help lubricate rollers and disperse heat. Below the rollers, shovel plate is installed. In the process of pulverizing, the shovel plate would rotate with the grinding rollers at the same time and play an important part in throwing up materials to feed them into grinding roller rings so as to form a padding layer. The padding layer is then ground into powder under action of outward centrifugal force generated by grinding rollers. The roller hanger of MRN Mill uses the mesh-typed design which ensures the ventilation area in grinding cavity and material conveying efficiency so that the whole grinding efficiency is elevated.
