Overview
MRN series trapezium mills are a perfect grinding machine, which could produce 80-400 mesh fine powder with large capacity. The biggest model could give 50 tph capacity with less powder consumption. Due to its stable performance, MRN series mills are widely used for making fine powder, which are mostly used for agriculture, chemical, paint, wall putty, steel plant, water treatment, etc.
Features
1. Less Occupied Area & Less Investment
MRN series trapezium mills has its own production system from bulk material to finished powder, with less investment in building plant and foundation.
2. Adjustable Output Fineness
MRN series trapezium mills adopts modular impeller adjustment device, which can produce products with different fineness only by changing impellers.
3. 60% Lower on Consumption than Ball Mill
MRN series trapezium mills has an energy consumption of more than 60% lower than that of the same grade of ball mill under ideal working conditions.
4. Higher Induced Air Efficiency
MRN series trapezium mills adopts high efficiency impeller fan, which improves the efficiency of air induction from 62% to 85%.
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.
