Mining Trapezium Mill

Mining MTW Series Trapezium Mill

Overview of mining MTW Series Trapezium Mill

MTW Series Trapezium Mill adopts bevel gear overall drive, inner automatic Thin-Oil lubricating system. As a latest grinding equipment, it adopts the European advanced technology.Our machine adopts many technology advantages of mill machine all over the world, such as trapezium’s working surface, flexible connection, roll linked pressure boost, etc.

Feature of mining MTW Series Trapezium Mill

1. MTW Series Trapezium Mill structure is compacter, easy to be installed and more efficient.

2. The main shaft bearing and bevel gear can be lubricated without an additional lubrication system.

3. MTW series mill adopts a cambered air channel, the tangential air goes into air channel easily.

4. The shovel edge of MTW series mill adopts high wearable limit alloy, its life will be longer.

5.Perfect outward appearance with advanced structure and beautiful arc structure design.. The efficiency and precision of classifying is promoted highly.


Principle of mining MTW Series Trapezium Mill

First, crushed stuff is elevated into a hopper from which the stuff is loaded . Then stuff is carried by the air into the separator for screening. The set’s airflow system is closely sealed up and circulated under condition of negative pressure . The process of MTW mill is saving costs and have big capacity .
