Product Introduction
MTW series grinding mill is designed by our experts, according to
collected advices from customers' long-term experiences. It takes
the most advanced patent technology from European and the supply
the customers with outstanding performance at low costs.
Application
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
Working PrincipleThe 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.
