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. Due to the low crushing ration, the thyssenkrupp Double-Roll-Crusher is producing a ...
Roll crushers can be configured with one, two or three pairs of rolls, depending on the application. Compared to hammermills, roll crushers can produce a more uniform grind at a much lower operational cost but cannot attain as fine a grind. Figure 3 shows a sieve analysis for a grind from a hammermill and a roll crusher.

Roll Crusher operation is based on the principle of continuous pressure generated between two counter-rotating rolls; allowing uninterrupted crushing, in contrast to the intermittent action of jaw crushers. During operation, the high rotational energy of the crushing rolls and the drive components reduces peak loads, resulting in a more regular ...
Roll Crushers. Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive.
