(PDF) Torque Analysis of a Gyratory Crusher with the
A gyratory crusher consists of a movable and truncated conical head and a fixed concave shell, as is presented in Figure 1 . The head is integral with the main shaft, and itMechanical Crushing and Grinding. Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Crushers. Crushers are widely used as a primary stage to produce the particulate product finer than about 50–100 mm in size. They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer Crusher an overview ScienceDirect Topics

Mathematical Modeling and Multi-Criteria Optimization of Design
This expression represents a curve equation of the working chamber profile of a single-roll gyratory crusher. A mathematical model was also established, which demonstrates a relationship between the target functions (performance, load variation coefficients) and the optimized parameters (the eccentricity magnitude and the initial angle of the working Crusher performance is significantly impacted by liner material wear, wear profile, feed size distribution, feed type, and feed rate (Bearman and Briggs, 1998). This work is based on cone crushers, but the similarities between these types of crushers and gyratory crushers suggest that the results may be transferable to gyratory crushers.Improved gyratory crushing operation by the assessment of liner
