comminution features in an impact hammer mill

Comminution features in an impact hammer mill ScienceDirect

Feb 01, 2013· A systematic study on the comminution of a soft (coal) and a hard (iron ore) material is carried out to investigate the bulk comminution features of the hammer mill. The effect of the feed rate and the rotor speed on the mill efficiency in terms of reduction ratio, energy expenditure, fines produced and median size is investigated.

Experiment And Model-based Investigation Of Comminution In

A numerical model based on DEM was used to simulate a hammer mill and study the breakage and kinematics of the particle motion within the hammer mill. In the simulations, increase in hammer tip speed causes higher frequency of impact of particles per unit time and higher specific energy of impact

Size reduction (Communition) SlideShare

Aug 05, 2018· Size reduction (Communition) 1. COMMINUTION The process of reducing the particle size of a substance to a finer state or powder is known as comminution. It is done with the help of mortar and pestle or mills. Different mills used for the reduction of particle size are hammer mill, ball mill, colloid mill, fliud energy mill
