Different types of particle size reduction equipment are available and each has its own method of reduction. The right size reduction machine for the task is the one that can add energy most efficiently for the application. From the beginning of time, humans have found it necessary to make little pieces out of big ones stone, ore, ice ...
Feb 28, 2020 A multi-row cage mill has multiple stages of impact reduction, which produces size reduction by adding energy to the feed. The material enters the center of the innermost cage, where it bounces around, getting struck until its small enough to exit that row. Particle impact velocity increases the farther from the center the material travels.

Size reduction by crushing has a size lim itation for the final products. If we requir e further reduction, say below 5-20 mm, we have to use the processes of grinding.
It is then passed through the narrow gap between the rotor and stator and thus reduced the fine particle size. A colloid mill is a hydraulic shear producing device. The colloid mill works to reduce the size of the suspended droplets. The mill allows the solid particles to become so small.
Abstract Size reduction is the operation carried out for reducing the size of bigger particle into smaller one by external forces. This reducing in size is done by using ball mill. In the experiment, the stone are weight about 100g and mix with two handhelds of grinding ball into the ball mill. The speed control knob is adjusted each at 40 rpm and 90rpm.
