CPM Europe typically designs Roller Mills for animal feed grinding. This results in a far more heavy-duty design than Roller Mills used in the flour milling industry. In the feed milling industry Roller Mills are used for grinding whole grains, soya kernels, pellets and other brittle ingredients to a particle size between 500 and 2000 micron. CPM Europe Roller Mills come in different sizes in either single pair, double pair or triple pair rollers for capacities up to 100 tph and are suitable for remote control allowing a different setting for each recipe produced.
Roller mill vs Hammer mill
Compared to the usual Hammer Mills, Roller Mills are extremely efficient grinders as the product is nicely “cut” by the corrugated rollers. This not only reduces the energy consumption, but also gives a better “grind” with less fines.
Roller Mills vs Hammer Mills
Roller mill
Grinds by shear
Narrow particle size range
Low fine and oversize content
Will leave fibrous particles in tact
Low energy input
Low temperature rise
No moisture loss
Higher fat contents less of a problem
Hammer mill
Grinds by impact
Wide particle size range
High fines content
High energy input
High temperature rise
High moisture loss
Fatty products tend to blind small diameter screens
