The roller crushers are used for moist and sticky materials. Generally the machines have to be rigid enough to crush also hard inclusions. As the reduction ratio is only about 5:1 a 2-stage crushing is required in most applications. Fast running type crushers like hammer and impact crushers are the simplest and cheapest solution, whenever the ...
