SANDVIK ROLL CRUSHER
Sandvik offers a wide range of different roll crusher types based on a proven technology with experience of more than 2000 installations. The double roll crusher CR420 is mainly used for secondary and tertiary
crushing of middle-sized materials. One beneﬁ t of the Sandvik double roll crusher is the ability to produce a narrow particle size distribution, thusminimizing the production of undesired product sizes. The smooth roll crusher CR450 offers a suitable solution for ﬁ ne grinding processes.
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’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.
