Roll Crusher

The theoretical capacity of crushing rolls is arrived at simply by calculating the volume of the ribbon whose cross section is the area of the discharge opening, and whose length is the peripheral speed of the roll faces per unit of time. The formula, for material weighing 100 lb per ft3, is: D x W x S /48 = TPH

Roll Crusheran overviewScienceDirect Topics

For example, a two-roll crusher with 24-inch-long (61 cm) rolls crushing to ¾ inch (2 cm) has a capacity of 75 tons/h (68 metric tons/h), which is approximately 2.5 times the capacity of a single-roll crusher with the same roll width and topsize setting.


Design, Fabrication and Testing of a Double Roll Crusher

density of roll crushers are low (0.15 0.3) Substituting yields a capacity, Q = 1.430 t/hr. The actual capacity of roll crushers is only about 25% of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q =


Chapter 6Roll CrushersScienceDirect

Roll crushers are arbitrarily divided into light and heavy duty crushers. The diameters of the light duty crushers vary between 228 and 760 mm with face lengths between 250 and 460 mm. The spring pressure for light duty rolls varies between 1.1 and 5.6 kg/m.
