· It’s a step that’s thought out well to ensure everything runs smoothly and gets the material ready in the best way for the next steps. Primary crushing happens when we take big rocks, even ones bigger than a meter, and make them into smaller bits. These bits are often between 150 and 200 mm. This step is very important.

· What’s A Jaw Plate. Jaw plates are the parts of the jaw crusher that direct contact with the material being crushed. They are rectangular in shape and are designed to fit around the crushing chamber of the jaw crusher. Jaw plates come in pairs and are positioned opposite each other, with one jaw plate being fixed and the other being movable.

· Abstract. In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.
