The first method is based on the roll’s geometry and the change of the HPGR chamber’s volume together with the roll rotation, while the second one considers the outlet gap width. Results of the nip zone angle calculations according to both methods are similar and show that the nip zone angle is around 3o. The verification was carried out in
Angle of Nip — The angle formed between the moving surface of a crusher roll or jaw plate and the stationary plate surface at which point the material will be pinched. Angle varies with machine size and material lump size. Bond Work Index (BWI) — Kilowatt hour (kWh) per short ton required to reduce the material to 80% passing 100 microns
angle of nip definition of angle of nip in the Free Online Encyclopedia. The largest angle that will just grip a lump between the jaws, rolls, or mantle and ring of a crusher.Also known as angle of bite; nip. (mining engineering)
The nip angle is affected by the distance between the rolls. The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface characteristics of the rolls. Usually, the nip angle is between 20 and 30 but in some large roll crushers it is up to 40
into the roll crusher is determined by the radius of the roll R, roll gap, L and the angle of nip . From Equation (3), the maximum size of the particle ( ) that can be fed into the machine is, = 2 = 7.5mm A hollow cylindrical shaft is used to build the roll, this hollow shaft’s thickness must be calculated to

ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. ... called the nip angle. The two rolls force the particle between their rotating surface into the
Roll Crusher. 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
