The HM 200 is equipped with a horizontal rotating shaft on which 10 freely swinging hammers are mounted. Those hammers crush the material at high speed inside the grinding chamber. With the swing hammers in contrast to fixed hammers, the risk of blocking the machine as well as the wear is minimized. The material is crushed by impact when hit by each hammer and while bouncing inside the grinding chamber. As soon as the sample is fine enough to pass through the sieve, it falls through the gravity outlet into a collecting vessel.
