Brief introduction

MTW European Type Trapezium mill is the newest grinding equipment which enjoys many patented technology and reaches the international advanced level. It is the up-to-date grinding equipment designed by our devoted research team, basing on feedbacks and advice from 9518 mill customers and rich experience on mill research. The mill enjoys several patent technologies, such as bevel gear overall drive, inner automatic Thin-Oil lubricating system, arc air channel, etc.

Working Principle

Firstly, raw material should be crushed by jaw crusher to the size specified, and then the crushed stuff is elevated into a hopper from which the stuff is loaded, through the vibrating feeder, evenly and continuously into the grinding chamber for power-processing. After this, the ground stuff is carried by the air into the separator for screening. The fine powder are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set's airflow system is closely sealed up and circulated under condition of negative pressure.

The New Technology As Below

1) Bevel gear overall drive: the traditional grinding mill is driven by speed reducer and coupling. It is hard to be installed. And there will be too much noise, and the efficiency is lower. MTW series mill is driven by bevel gear, so its structure is compacter, easy to be installed and more efficient.

2) Inner automatic Thin-Oil lubricating system: the traditional mill adopts grease lubrication, so the lubricating resistance is stronger, the temperature will be higher soon, and the bearing lifespan is shorter.

3) Arc air channel: The entire air channel of traditional grinding mill is upright board type.

4) Cambered shovel with renewable edge: The traditional shove is integral and edge always be worn out quickly, so you have to renew it in short time which affects the working time and wastes too much steel.

5) Separated cyclone: There is a separated structure between inner piping and mixed air and powder. The efficiency and precision of classifying is promoted highly.
