MTW Trapezium Mill Introduction

The MTW Trapezium Mill is mainly applied to the powder processing of mineral products in the industries of mining,metallurgy,chemical,and contruction materials,etc. They can produce powder from various non-flammable and non-explosive mineral materials with Mohs hardness below9 and humidity below 6%,such as quartz,feldspar,calcite,talcum,marble, ceramics,iron mine,soft coal,dolomite,active carbon,plum sandstone,basalt,etc.

MTW Trapezium Mill Technical Advantage:

(1) Inner lubrication system: MTW Trapezium Mill adopt light-oil lubrication to achieve the lubrication between the main bearing and gear bearing, without oil pump or lubrication station. The traditional mills’ lubrication adopts grease lubrication which increases the resistance of lubrication, creates high inherent temperature and shortens the service life of bearing.
(2) Main shaft transmission: MTW Trapezium Mill adopt bevel gear integral transmission ,which will better compact the whole structure,simplify the installation as well as improve the efficiency.The traditional mill needs decelerator and ratcheting to drive the main shaft that increases the installing difficulty and is easy to bring noise and reduce the efficiency.
(3) Arc whirl tube:MTW Trapezium Mill adopt arc whirl tube to reduce the resistance and avoid the air-stop and so on. The traditional mills adopt board-type whirl tube that increases the resistance, reduces the performance, and stops the air flow and so on.

MTW Trapezium Mill Working Principle:

1)Raw material which has been crushed to the size specified is elevated into a hopper from which the stuff is loaded. And then through the vibrating feeder ,the materials will 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 decelerator ,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
