Working Principle of Ball mill: As the mill rotates, steel balls work to grind the materials. The mill rotates approximately once every couple of seconds. The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product.

4. Hammer mills : The principle of operation of hammer mill is shown in Figure C. These mills have swinging hammers or bars, into the path of which is fed the coal to be pulverized. Grinding is done by a combination of impact on the large particles and attrition on the smaller ones. Hot air is given to dry the coal. These mills are excellent ...

The working principle of a hammer mill is to have a rotor, equipped with hammers (thick plates) rotating at high speed within a casing, that may be equipped with a grid, and that reduces the size of the feed material by impacting them. Hammer mills are designed with a shaft on which are mounted several "hammers" which have most of the time the ...

3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.
