Laws of comminution
WebWe offer comprehensive testing to produce all the breakage parameters required by JKTech’s comminution and classification circuit simulation software JKSimMet, a global industry standard for circuit design and optimisation. JKTech offers a range of comminution tests depending on the purpose, data use and sample size. WebIn 1967 RITTINGER presented the so called "First law of comminution", which postulates that the new surface created by the comminution process is di- rectly proportional to the energy input. This means that the energy input, Ep, is …

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in … Meer weergeven The comminution of solid materials consumes energy, which is being used to break up the solid into smaller pieces. The comminution energy can be estimated by: • Rittinger's law, which assumes that the energy … Meer weergeven • Mill (grinding) – Device that breaks solid materials into smaller pieces by grinding, crushing, or cutting • Particle size distribution – … Meer weergeven There are three forces which typically are used to effect the comminution of particles: impact, shear, and compression. Meer weergeven There are several methods of comminution. Comminution of solid materials requires different types of crushers Meer weergeven
