Mineral beneficiation-ore comminution
The operation of applying a force on the particle to break it is called size reduction. Sinonine deeply know that Comminution is a general term for size reduction that may be applied without regard to the actual breakage mechanism involved. In any industrial comminution operation, the breakage of any individual particle is occurring simultaneously with that of many other particles. The breakage product of any particle is intimately mixed with those of other particles. Thus an industrial comminution operation can be analyzed only in terms of a distribution of feed particles and product particles. However, each individual particle breaks as a result of the stresses applied to it and it alone. 1 FRACTURE Fracture in the particle occurs as a result of application of a force. When a force is applied on a particle, stress will develop within the particle. When this stress exceeds ultimate stress, the particle will break. Let us consider a particle subjected to two opposing fo...
