capacity calculation of double roll crusher

  • 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 = .356 t/hr 2.1.9 Crushing Power

  • Roll Crusher an overview ScienceDirect Topics

    Double-roll crushers are able to crush more finely than single-roll crushers, because they are designed with teeth that mesh together rather than rotating past a smooth plate. They can reduce coal to as little as ¼ inch (0.6 cm) topsize, although they are more commonly operated close to 2 inches (5 cm). They have a higher capacity than comparable single-roll crushers. 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

    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

  • Double Roll Crushers McLanahan

    Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds. They are one of the most widely used crushers in the mining industry and have numerous advantages, such

    BJD Double Roll Crushers are robust machines that are particularly suited to the reduction of a variety of friable materials of medium hardness such as coal, coke, limestone, clay and medium hard shales. As their name indicates, they crush the material between two rolls. Dependent upon application, the two rolls can be either renewable toothed breaking segments or smooth rolls. A wide range of

  • Crushing of coal and calculation of size reduction efficiency.

    25.02.2015· • The main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • Low capacity • Low reduction ratio = F/P • Sensitive to top size 2/25/2015 6:58:05 AM 38 39. Capacity calculations • Capacity = D π x RPM x L x S x Bulk density • D is the Diameter of Rolls • L is the length of the rolls • S is the set of the


    Roll crushers perform better than other types of crushers when fed wet and sticky materials. (These crushers are not intended for highly abrasive material such as gravel or taconite unless presence of clay, permafrost or similar material prevents use of other crusher design). 4. Single roll crushers often require less horsepower and lower headroom in comparison to other primary reduction
