Roller Mills


Roller Mills

Increasingly stringent requirements being made of product properties mean that comminution processes in the bulk materials industry today must satisfy significantly higher standards.

Requirements that SIEBTECHNIK roller mills for applications in the mineral and metal industry, the food industry through to the chemical and pharmaceutical industry are well up to.

Our roller mills are capable of comminuting very hard through to soft products homogeneously and with a minimum fine material content, depending on requirements, to a reduction ratio of between 1:5 and 1:1.5 and our double-roller mills to a Mohs hardness of up to approx. 8.5.
 

Single-roller mill

With the single-roller mills, brittle, soft to medium-hard materials can be reduced in size with a reduction ratio of approx. 1:5 to 1:5.
The stepped arrangement of the crushing jaws on the crushing wall enables any material rolling off being minimised, so that, compared to the double-roller mill, coarser material can be drawn in.
 

Double-roller mill

With the double-roller mill, all brittle materials, such as, for example, ores, clinker, limestone, gypsum, aluminium oxide, glass, … can be reduced in size up to a Mohs’ hardness of approx. 8.5 with a reduction ratio from 1:2 to 1:5.
