Crusher Feed Size and Roll Diameter. The diagram in Figure #3 shows the method used in calculating maximum feed size for any diameter of rolls; the accompanying table gives a listing of feed sizes for standard diameters. These figures are based upon zero roll spacing; therefore the distance between faces (i.e., the discharge spacing to be used) should be added to them to obtain the maximum

Roll Crusher an overview ScienceDirect Topics

For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions. Normally, one roll is fixed while the other roll is movable against spring pressure. This permits the passage

Single Roll Crushers McLanahan

The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a 6:1 ratio of reduction while producing a considerably lower percentage of fines. When properly fed in the direction of the roll rotation, the crushing action is carried out along the full width of the curved crushing plate, which ensures maximum throughput capacity. A properly sized roll diameter

What is a roll crusher? Mineral processing equipment

We use roll crushers in the tertiary crushing step, but they can be used in secondary crushing in some cases only if they are toothed. They are sized according to the feed material maximum size, and the capacity (tons per hour), in addition to other factors. Capacities of industrial roll crushers range from 100t/h to 1200t/h.

Selecting the Right Crushing Equipment Agg-Net

Maximum feed size varies with each model, but is generally limited to around 600–900mm. The output gradation of the primary HSI crusher is generally coarser than the primary breaker due to the lack of expansion above the rotor, which also affects the capacity. Primary HSI crushers are considerably wider than primary breakers at comparable capacity ratings.
