MTM Trapezium Mill

Trapezium Mill is the latest grinding mill. Supper Pressure Trapezium Mill is researched and designed by our experts basing on long term experiences of mill research and development, and according to numbers of customers' using requirements and suggestions home and aboard. The TGM Series Super Pressure Trapezium Mill adopts our patented technologies, like trapezium working surface, flexible connection, roller linked pressure boost, etc. Pressure Trapezium Mill has reached the advanced international level of powder making equipment manufacturing.


MTM Trapezium Mill Working Principle:

Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are elevated to storage hopper by bucket elevator, third, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separating by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugal blower through wind recycling pipe at the upper part of cyclone powder collector. The mainframe is driven by the speed reducer through the central axis in the mill. The quincunx stand connected with the upper part of central axis, at the quincunx stand, rollers are set and by which the vibrating pivot formed. Below the quincunx stand and rollers there is shovel system. Materials are fed into the space between rollers and shovels when they are turning, and then be grinded by the pressure produced when rollers are turning, thus powder is made.

MTM Trapezium Mill Technical Advantage:
1. Effective grinding effect.
2. Outstanding spring structure.
3. High capacity.
4. Low energy consumption.
5. Convenient to adjust the fineness.
