Double Roll Crushers are one of the most widely used crushers in the mining industry and have numerous advantages, such as high capacity, low headroom, low horsepower, the ability to handle wet, sticky feeds and the ability to produce a cubical product with minimum fines generation. Roll diameters and widths are dictated by the feed size ...
Roll Crusher Capacity The capacity of the single-roll crusher is influenced by the nature of the feed to a much greater extent than is the case with any of the types discussed heretofore. The two factors which have a very important bearing on capacity are thickness and hardness, or toughness. Blocky material which must be broken on top of the ...
Double-Roll-Crushers are used for the crushing or medium-hard rock as well as for sticky and soft materials, i.e. clay, marl, limestone and similar raw materials. Sticky and soft materials are reliably crushed in 2 or 3 stages down to the required product size.
Each Double Roll Crusher is selected and engineered for its specific application, thus roll elements and tooth patterns are selected based on the customer's unique applications and designed to produce a cubical product with minimal fines.

Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.
Are roll scrapers or differential roll speeds required to provide a self-cleaning action to prevent material build-up on the roll surfaces? Is water being added? The differential in roll …
Potash Corp. Allan took a unique approach when looking for their new primary crusher.
