FEED MATERIAL

Double roll crusher CR420: raw materials, secondary raw materials and by-products such as sinter, coal, soft and medium-hard rock, fertilizers or salt. Smooth roll crusher CR450: especially for coke breeze / anthracite in sinter plants, oil shale and ash.

MODE OF OPERATION

The crushing rolls are individually driven in counter rotation by ample drive arrangements. The crushing material is fed into the machine by conveyors or similar systems while it is spread over the whole width of the roll. This is necessary to achieve an optimum use of the crushing tools, a minimum of wear and a uniform fi nal grain size distribution.

Parameters like roll diameter, tooth form or circumferential speed are carefully adjusted to the characteristics of the feed material in relation to the required product specifications.

SANDVIK SERVICE

Sandvik’s global network provides reliable and effi cient customer support. Spare parts availability and a comprehensive range of services allows improved productivity and maximized plant efficiency. This concept is already implemented in the design phase of the machines. 

Fast and easy replacement of components and wear parts, including the crushing segments or picks, minimizes unplanned plant downtimes.
