High-efficiency and low consumption

With the same end-products fineness and motor power,its output is over 1 time to that of Jet Mill,Mix Mill,and Ball Mill.

Easy-damaged parts with longer working life

The grinding roll and ring are made of special materials.Generally,their work life is more than one year,but,which ould come up to over 3 years,when it process calcium carbonate and Calcite.

Security and Reliablity

Because there are no roling bearing and bolts in the grinding chamber,we can not see the problems of bearings and sealings easily damaged and mahine destroyed due to the bolts loosenness.

Cleansing and Evironment Protection

Adoption of Pulse dust collector and muffler reduces the industrial dust pollution and noise,which reaches the National Standard.

working principle

The main bearing and each dial are driven by electromotor of main equipment through reducer,and numbers of rings and rolls which are rolling in the ring channels are driven by dial through plunger.After being crushed by hammer crusher,the big materials become small ones and they are sent to the storage bin by elevator.The elevtromagetic vibrating feeder sends them to the edge of dial evenly.
