It is at this point where a Double Roll Crusher must be used instead of a Sizer. The design of the Double Roll Crusher allows for a finer adjustment and therefore a finer product size. Cost. With the design differences also comes cost differences. The Double Roll Crusher is the more cost-effective option of the two.
Product quality is measured in terms of particle shape and mechanical properties. The crusher and feed parameters used are closed side setting (CSS), speed, feed rate and feed gradation. This paper presents a parameter study investigating the effect of feed and jaw crusher parameters on the quality of aggregates produced from single-stage crushing.
