The Working Principle of Hammer Mills (Stepbystep Guide) A hammer mill is an essential machine in the pharmaceutical and food processing industries. You can use it to crush, pulverize, shred, grind and reduce material to suitable sizes. Even though there are many types of hammer mills, the working principle is still the same.

Hammer Mill A finer particle size can be achieved in comparison to a roller mill. With proper filtration, the hammer mill allows for more efficient use of malt grains by increasing surface area. It requires less grain to make the same amount of beer when using a hammer mill. Modern method, reduces particles using impact .

The hammer mill, also known as the Pulverizer, works according to the principle of impact grinding. Its core consists of a rotor with wear resistant impact hammers and external housing for the roller bearing. The NEA hammer mill HM is highly suitable for grinding soft to mediumhard materials such as minerals, hydrated lime, bauxite and plaster.

Hammer milling is a high energy process of reducing particle size (comminution) by impact with rapidly moving hammers. The material is fed into the mill's chamber through a feed chute, typically by gravity, where it is struck by rapidly rotating hammers that strike particles repeatedly until the particles are reduced to a size that can pass through a nearby screen.

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 heat the hammer at high speed, but also be sent against each other or against the screen at high speed.
