Working principle of MTW trapezium grinding mill

1. Raw material which has been crushed to the specific size is elevated into a hopper from which the stuff is loaded. And then through the vibrating feeder ,the materials will be transferred evenly and continuously into the grinding chamber for powder-processing. After this,the ground stuff is carried by the air from the blower into the classifer for regrinding.The set’s airflow system is closely sealed up and circulated under the condition of negative and positive pressure.

2. The grinder is driven by rotation of the central axle through gear ,with the up end of the axle connecting to a quincunx-rack upon which the grinding equipment is fixed. The whole set equipment turns together with the axle along the grinding ring while the rollers rotate driven by the fractional force .A set of shovel are installed at the lower end of the quincunx-rack.While turning together with the rollers ,the shovels shed the stuff onto the gap between the rollers and the ring ,and that’s where the stuff layer forms .The rotating rollers ,while turning together with the ring ,grind the stuff layer into powder.

3. The turning speed of the impeller can be adjusted to the requirement of the fineness of powder products .

4. It plays an important role in ensuring the function of the grinder . As the high-speed revolving air current mixed with ground stuff is flown into the cyclone-collector ,the ground stuff is separated from the air-current .
