Rock mill introduction:
This type Rock mill plant is elaborately designed by our grinder engineers through the customer's production requirement and actual using experience, and also is a kind of new type high performance grinding equipment. Comparing with the traditional trapezium grinder and high pressure supension grinder, it has many advatages. It is widely used in glass, rubber, pesticide, porcelain enamel, paint, phosphate fertilizer and paper making, etc chemical industry. And it is used for grinding the Moh's hardness is below 9.3, humidity is 6% and non-flammable, non-explosive materials like talcum, barite, calcite, limestone, manganese ore, iron ore, ore, quartz, gypsum, bentonite, etc.

Working principle of Rock mill:
After reducing driving force of the main motor by the gear reducer, when the drive center axis and the quincunx rack fixed on the center axis revolve, under the centrifugal force the roller revolves around the center axis, at the same time parallel swing around the shaft, making the roller compress out side to the ring, thus ensure that the roller and ring has maximum surface contace. At the same time the roller self revolves around the roller shaft, making the material scooped up by the shovel blade to grind, after grinding the powder blew to upper part of the mainframe, the separating by the separator, too coarse powder drops to the grinding room to re-grind, the qualified powder airflows into the cyclone powder collector, through the discharging pipe is qualified product.

MTW series mill is mainly applied to the material processing of metallurgy, building materials, chemical industry, mining and other industries. It can grind limestone, calcite, marble, talcum, dolomite, bauxite, barite, petroleum coke, quartz, iron ore, phosphate rock, gypsum, graphite and other non-inflamma-ble and non-explosive mineral materials with Moh's hardness below 9 and humidity lower than 6%.

Main Structure

The raw material will be fed into the jaw crusher to be crushed to below 30mm. The bucket elevator will load the crushed material below 20mm and then feed it into the main mill through a hopper and a vibrating feeder. The main mill drives the center shaft to rotate through the reducer. The top of the center shaft connects with a grinding roller hanger. The rollers are installed under the roller hanger through the cross arm shaft and form a swinging pivot. The grinding roller rotates around the center shaft of the main mill along the grinding ring. At the same time it also rotates itself under the action of the friction with the grinding mill. The shovel blades system is equipped in the bottom of the grinding roller hanger. The shovel blade and rollers can throw up the material and feed it into the space between the rollers and ring so that the material can be crushed and grinded. The air flow from the bottom of the grinding ring will take small powder into the classifier. After the classification by the classifier, the coarse particles will fall down to be grinded again and the qualified powder will be fed into the powder collector together with the air flow. The it will be discharged from the pipes as finished products.
