Comminution Pdf Fracture Stress Mechanics This document discusses comminution mechanisms, which are the ways that particles fracture during size reduction processes. it describes four main mechanisms: shatter (impact fracture), cleavage, attrition, and abrasion. Comminution by hadi free download as powerpoint presentation (.ppt .pptx), pdf file (.pdf), text file (.txt) or view presentation slides online. comminution is the process of reducing particle size, essential for improving solubility, mixing, and flowability in pharmaceuticals.
Comminution Of Minerals With Grinding Pptx Comminution theory and laws • comminution theory is concerned with the relationship between energy input and the particle size made from a given feed size. • rittinger's law (1867), states that the energy consumed in the size reduction is proportional to the area of new surface produced . Energy requirement • kick model kick (1885) proposed that the finite energy required is proportional to the change in particle size ∆x relative to the initial particle size x. Sidra jabeen department of chemical engineering, university of engineering & technology lahore large size particles are converted into smaller particles. the process is also called as comminution. size reduction size reduction methods compression. The comminution theories are concerned with the relationship between the energy entering the comminution process and the sizes of particles leaving the comminution process from a certain feed size.
