But for vertical roller mills, the growth rate of that of material will gradually decrease. From this point of view, roller press is superior to vertical mill. In roller press, the contact area between the two rollers and the material is small; the material is ground by only passing through the roller press once due to the large grinding ratio.
A roller press, also known as a kompaktor, roller press or briquetting press, is used to compact fine-grained materials into solid press agglomerates. This can be used to produce flakes or briquettes. In combination with grinding and classification technologies, it is possible to achieve dry granulation.

The feeder (A) deposits raw material into the base of the Roller Mill (B) at a rate determined by pressure variations with the grinding mill. Plows located ahead of each roller direct the material upward and between the grinding rolls and the heavy alloy steel bull ring, where it is ground to the specified size.
All conventional roller mills have fixed roller spacing or spacing adjusted by screws. In operation the hot metal is fed in one side and out the other. ... Where a small hydraulic press for forging laminated steel takes 10 to 15 horsepower and probably a 3 phase 220 volt service, the McDonald Mill does the same job faster and better
