Solutions To Improve The Production Capacity Of Jaw Crusher
1. Adopt Proper Nip Angle. The nip angle means the included angle between movable jaw plate and fixed jaw plate. According to calculation, the max nip angle can reach to 32°, but in the actual production, the nip angle is generally between 18°-20°, smaller than 25°. If the nip angle is too large, the raw materials in crushing cavity will be ...

Choosing the Right Jaw Crusher Size and Capacity for …
Nip 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 maintenance.
