The roll crushers are not as productive as cone crushers, with respect to volume, and they do have a little higher maintenance associated with them. Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs.
From Jaw Crushers, to Hammermills, to Double Roll Crushers, an option likely exists within the McLanahan product offering that will meet your low tonnage, high dependability requirements. Sampling and pilot crushers are used with the same types of materials as their larger counterparts. The key difference is comparatively low feed rates.
Roll crushers vs hammer crushers Both are used in the secondary or tertiary crushing process but still have many differences. Roll crushers reduce material by force generated from two relatively rotating drums. First, the material enters the feed opening along with the high-speed rotating roller drums, then it got crushed by strong …
The types of crushers typically found in sampling applications include Hammermills, Roll Crushers, Jaw Crushers and Cone Crushers. In this blog, we look at how these different types of crushers work, their reduction ratios and what type of material is best suited for each. ...
