McLanahan What Type of Crusher Is Best for Primary Crushing?
Hammermills can be used as a primary crusher in many types of aggregate and industrial applications, including limestone, marble, shale, gypsum, phosphate, bauxite, aluminum dross, uranium, cryolite, clinkers, quicklime, petroleum coke, coal and more. Using a combination of impact, shear and attrition reduction methods, The Discrete Element Method (DEM) is a numerical method that is able to simulate the mechanical behavior of bulk solids flow using spheres or polyhedral elements, offering a powerful tool for equipment design and optimization through modeling and simulation. The present work uses a Particle Replacement Model (PRM) embedded in DEM Simulation of Laboratory-Scale Jaw Crushing of a Gold

Jaw crusher..3*1 sq. ft Gyratory..10-9 sq. ft. An important advantage of the jaw crusher over the gyratory crusher is that of being able to deal with materials having a high clay content, although this advantage is less where discharge openings are large. Secondary Crushing:Currently,the gold ore processing methods are as follows: First of all, send the large gold ore to jaw crusher evenly and continuously for primary crushing by vibrating feeder. And then, transport the crushed gold ore to cone crusher for secondary crushing. Then, we need to use a vibrating screen to separate the gold ore into different sizes.Gold Ore Crushing Process and Gold Crusher sbmchina
