Roll Crusher for Sale The standard spring roll crusher have two horizontally mounted cylinders. The set is determined by spacing pieces (shims) which cause the spring-loaded roll to be held back on its sliding mounting from the solidly mounted roll. Modern rolls have both cylinders positively driven by separate motors, so that they rotate inward and downward. Rolls crush by …

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.

With a Double Roll crusher, the material is drawn and forced between a large-diameter roller and an adjustable liner. The maximum size of material that can be fed to a roll crusher is directly proportional to the diameter of the rolls. Triple roll crushers are manufactured to provide two-stage reduction all in one crusher assembly.

To evaluate the effect of liner wear on cone crusher size reduction, a similar test sequence is first performed for a crusher with fully worn liners and then for the same crusher with new liners. Based on the acquired data, relative production curves and performance maps J 1-J 4 are finally established using ordinary least squares.

A good rule of thumb for single-stage crushers is that a Single Roll Crusher provides up to a 6:1 ratio of reduction and a Double Roll Crusher provides up to a 4:1 ratio of reduction. In the event that the application requirement exceeds the guidelines discussed herein, dictating more than one crushing stage, then a determination will have to ...

Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.
