Vertical roller mills for limestone in heavy-duty design with smooth rollers are used for crushing brittle, medium-hard to hard materials with a degree of reduction of approx. 1:4 to 1:10. For customers’ production needs, ZENITH has manufactured lots of high quality and advanced mining machines depending on over 20 years’ abundant production experience.
The vertical roller mill used for limestone has two crusher rollers which can be made of highly wear-resistant steel, carbide or ceramic. Selection of suitable material may cause undesired contamination through wear to be avoided in the best possible manner. One of the two rollers is rigid, the other one being set against springs, so that protection against overload and small foreign bodies is ensured. The crushing space is limited laterally by locking plates, closing at the end faces of the rollers.
