A. the ring die pellet mills were designed at around the 1930s based on the design of ring die. the basic pelleting principle of the ring die pellet mill is a simple operation where feed mass is distributed over the inner surface of a rotating, perforated die ahead of each roll, which compress the feed mass and compress it into the die holes to form pellets.

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 advantages of roll crushers are they.

Determination Of The Nip Angle In Roller Compactors
In roller compaction, the nip angle defines the critical transition interface between the slip and nip regions which is used to model material densification behavior and the properties of compacted ribbons. current methods to determine the nip angle require either sophisticated instrumentation on sm.

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.
The limestone travels into the nip area 36, which is the area just above the nip 30 between the rolls 18, 20. grinding of the limestone particles occurs in the nip area 36 and nip 30 within a dwell angle of about 15 to about 30 as indicated at α in fig. 2.
The nip angle is the angle at which the material, that passes through the crusher inlet to be crushed between the jaws can be gripped by the jaws without slipping. this angle depends on the size, hardness and frangibility of the material. it cannot be selected as too large or too small. the nip angle in primary crushers is lower than in.
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.
