MTW European Type Trapezium mill is the newest grinding equipment which enjoys many patented technology and reaches the international advanced level.

It is suitable to process non-flammable and non-explosive materials with moisture less than 6% and Mohs’ hardness less than 9 such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, magnetite, iolite, vermiculite, barite, gypsum earth, fluorite, etc.

  1.Linkage supercharging device of rollers, stable operation and advanced productivity.

  2.Bevel gear overall drive, less energy loss, higher efficiency.

  3.With reliable and advanced technology of Inner automatic Thin-oil lubricating system.

  4.Arc air channel, less air flow loss, better material fluidity.

  5.Special design of rollers and ring, replaceable curved shovel edge, higher efficiency and lower cost-in-use.

  6.No resistance snail shell.

  7.Adjustable output size, efficient powders production.

  8.High efficiency and precision of powders collection.

  9.Humanized design, easy to use.

  10.Environmental protection.

First, raw material should be crushed by the 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.
