Crushing Applications Steve Lovell Introduction Large bevel gears drive the crushing machines used to process ores and minerals in the hard-rock mining and aggregates industries. Among the most common machines of this type are gyratory (Fig. 1) crushers and cone crushers (Fig.2). The gyratory crusher is typically the first process step after

The crusher is the workhorse of the hard rock crushing industry. A gyratory crusher uses a mantle that gyrates (rotates) within a cone shaped inner surface lined with wear resisting plates often called concaves. As the mantle gyrates within the crushing chamber, progressively approaching, and receding from, each element of the cone

Crushing is the first step in converting shot rock into usable products. Essentially, crushing is no m ore than taking larg e rocks and reducing them to sm all pieces. Crushing is som etim es continued until only fines remain. At some operations, all the crushing is accomplished in one step, by a primary crusher. At

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.
