Designing a Crushing & Screening Plant – Part I. Primary Jaw Crushing Stage
A good rule of thumb for equipment capacity in a primary crusher stage is therefore to aim at 70-75% capacity utilization. This will normally give enough margin to handle the given uncertainties in operating conditions. Another good rule of thumb for the design of jaw crusher stages is to start with the same setting on the grizzly separation and the jaw crusher CSS. This will often create good

4 Types of Stone Crushers' Maintenance and Efficient Improvement | Fote
2 Jaw crusher parts especially jaw plates wear badly. Materials that need be crushed is irregular and with different hardness, so it will bring constant friction and stress to the jaw plates. At the same time, moveable jaw moves up and down in vertical direction, which leads to stronger friction between material and jaw plates thus damaging the surface of the jaw plates.
