DetailsThe nip angle is the angle between the fixed and movable jaw dies. Too large a nip angle reduces the capacity and increases the wear as the feed material grinds and gouges the jaw dies in an upwards direction during the compressive stroke of the pitman.
DetailsNip Angle: The nip angle is the angle between the fixed and movable jaw plates. A steeper nip angle means that the crushing chamber is deeper and narrower, which can improve crushing efficiency and reduce the risk of material slipping. However, a steeper nip angle can also increase wear on the jaw plates and require more frequent …
DetailsThe 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°.
DetailsFigure 3: Angle of nip in a jaw crusher 2.3 Crusher Jaw Plates Compression of materials undergoing crushing in a jaw crusher is achieved when the movable jaw presses the feed against a stationary jaw. These jaws can be flat surfaced or corrugated. Crusher jaws were formerly made of white cast iron and later with high manganese austenitic steel ...

DetailsA review on the design and operations challenges of a single toggle jaw crusher is presented. Strength and fracture toughness of the material to be crushed are intrinsic properties that determine the time and energy required to crush the material. Economy of the crushing process is partly dependent on the angle of nip. Productivity …
DetailsFrom Allis-Chalmers' Superior Primary and Secondary Crushers. ° Actual required depends on stone hardness, reduction ratio, and so on. If a 60-in. gyratory crusher is to process material from a quarry where a shovel loads the raw material, the shovel would probably have to have a dipper capacity of at least 5 cu yd to be compatible.
Details2.2 Angle of Nip The jaws are set at an acute angle to each other. This angle commonly known as the "angle of nip" is usually less than 26o. This is due to slipping effect when …
DetailsApply the proper jaw die profile. There are many kinds of rocks, differing in crushability, abrasiveness, flakiness, etc. Choosing the best combination of fixed and movable jaw dies profiles will help to optimize production when crushing difficult material. A Rock of low crushability requires a closer nip angle to keep the capacity as designed.
Details5. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls. Some major …
