 roller mill]] has many different forms, but it works basically the same. All 
of these forms of machine comes with roller (or the equivalent of roller 
grinding parts), and roller along the track of the disc at the level of 
circular movement imposed by external grinding roller in the vertical pressure 
on the disc on the material being the joint action of compression and shear, 
and to crush.  Material grinding process: motor through reducer rotating drive 
disc, the material falls from the mill under the central entrance and exit, 
under the action of centrifugal force to the disc edge by the roller to move 
and the crushing, grinding out lap after the material was speed up the flow to 
and vertical mill with one of the separator, after the meal by the separator 
back to the mill, the re-grinding; powder while grinding out with air, dust 
collection equipment in the system to collect down, that is, products . 
Established through the mill in the pneumatic conveying of materials, a larger 
air flow rate, which can use waste heat of gas, at the same time dry grinding 
operations.

Roller Mill]] Principle: Used in cement grinding production grinding parts of 
its various forms, there is a cylinder, cone type, ball type, etc., and roller 
surface is also flat, curved, convex round noodles. Applied to the grinding 
roller to roller grinding along the track bed in close contact with the 
material strength of a spring pressure, hydraulic, etc..

+ == How Vertical Roller Mill Works ==
+ It has two pairs of grinding rollers, each pair of roller composed of two 
narrow rollers, mounted on the same axis and can rotate at different speeds. 
There are two circular disc slot, and roller to the tire shape, work pressure 
in the tank. Disc roller and the relative sliding velocity between small and 
roller can swing, even if the roller sleeve and the disc after the liner wear 
can guarantee a good abrasive, will not affect the grinding effect. Roller 
symmetrical structure, one side can be upside down after use and wear. 
+ Material grinding process: hydraulic pneumatic roller device through the 
pressure applied to the material on the crushing of materials, the materials 
have been moved to crush the edge of disc, from the disc around the nozzle from 
the exhaust air to improve these materials to Separator.Meal to separate 
returns after a concentrated mill, fine powder was collected in the 
precipitator unloading. In the gas flow is small, the meal can not be increased 
to enhance air flow, they would fall through the nozzle discharged outside the 
mill, bucket elevator to be transported to the feeder of vertical roller mill, 
and was re-grinding mill feed people. This cycle features of the way there:

efficiency;
