This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.

Hammer milling parameters such as screen size, blade selection and rotor speed can be optimized for each application, depending on the equipment used. The typical particle sizes that can be achieved with hammer mills is a D 50 between 150 μm and 600 μm. Hammer mills tend to yield less than 25% of particles below 150 μm.

The simplest way to describe the concept of size reduction is to look at the industrial hammer mill model: Hammer mills operate on the basic principle that most materials will crush, shatter or pulverize upon impact. This is accomplished by a simple four step process: Material is fed into the mill, typically by gravity.

Hammer Milling Hammer mills, technically a subset of impact crushers, employ tiny hammers (also called beaters, which may be blunt or sharp) mounted on a rotating shaft inside a drum to repeatedly impact material — using impact, shear, and centrifugal forces — to reduce material, usually to intermediate particle sizes. Hammer mills are

Our RMS 4 roller mill for preground malt has recommended starting gaps set to 4 thouhs of an inch (.102mm), and 3 thouhs of an inch (.076mm). From those starting points we adjust the mill to achieve the desired particle size. While the mill gap is the adjustment made, it is more important to measure the resulting grist.
