[ ′aŋ·gəl əv ′nip] (mechanical engineering) 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) In a rock-crushing machine, the maximum angle subtended by its approaching jaws or roll surfaces at which a specified piece of ore can be gripped.
Patented hydraulic beam locking system, Excellent nip angle, Fabricated main frame and swing jaw, Reversible jaw dies for maximum wear, Relief / adjustment FEATURES The single toggle crusher is designed for a high capacity throughput due to the elliptical movement of the swing jaw which also assists in the discharge of the crushed material.
• Radial thrust tapered roller bearings, the best design for absorbing and withstanding shock, radial and thrust loads. • Longer jaw length to provide increased crushing area, steeper nip angle and increased capacity. • Curved jaw dies to provide non-choking crushing action, reversible for increased wear.
The calculated nip angles were validated against those obtained from physical measurements during actual roll compaction. These nip angles were in agreement for various powder formulations containing plastic and brittle materials. The nip angles ranged from 4° to 12° and decreased significantly when the proportion of brittle material increased.
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°. 3. Roll Crusher Sizes and Design
Angle of nip (Sudut jepit), pada jaw crusher didefinisikan sebagai besar sudut yang dibentuk antara kedua jaw, sementara pada roll crusher, sudut jepit adalah besar sudut yang dibentuk antara tangen dari permukaan roll yang kontak dengan material.

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 …
The correct nip angle between the movable and fixed jaw dies ensures good bite and material flow down, even with slippery feed material. It also reduces wear on the jaw dies, reducing operating costs. With a good grip, the jaw crusher can crush rocks efficiently through the entirety of the cavity, and the nip angle can be further improved with an

2 Roll crusher is also called double roll crusher, double teeth roll crusher etc. The surface of roller crusher are made of high manganese steel, which can stand up to heat treatment. Double roller crusher is suitable for rough and intermediate crushing of brittle materials in such industries as cement, chemical industry, electric power, mine ...
Jaw Crusher Features: Excellent bite in the cavity. The steep nip angle, the angle between the movable and fixed jaw dies, ensures good bite and good material flow down in the cavity. High production and reduction. The stroke is amplified from the top to the bottom, which means that the stroke is always longest in the bottom of the cavity.
Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls ...

Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°. 6.2.1. Roll crusher sizes and design
These roll crusher for crushing material have applications in multiple industries. ... The particles are drawn into the gap between the rollers by their rotating motion and a friction angle formed between the rollers and the particle, called the nip angle. The two rollers force the particle between their rotating surface into the ever smaller ...

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.
