Cracking rolls & smooth rolls
Cracking rolls
are used for milling, reaming, crushing, breaking and flaking. The resistance to wear increases the economical efficiency of the milling process. Additional advantages of high-quality rolls are longer maintenance intervals, reduced repair costs and lower energy requirement.
“The higher the quality of the roll material and the more exact the roll geometry,
the better and more even the quality of the milled material.”

Smooth rolls
are used for squeezing.
“The better the squeezing behavior of the smooth roll,
the higher the production reliability of the roller mill.”
