Abstract

The utility model discloses a millstone-type hammer crusher. The millstone-type hammer crusher comprises a feeding hole, a hammer, a rotor, a sieve, a sieve pressing frame, a discharge hole, a crusher body and a motor, as well as a millstone frame and a millstone arranged on the millstone frame. When being fed, the material is crushed not only by a hammer-sieve clearance between the hammer and the sieve of the crusher but also by crushing effect generated by the hammer-millstone clearance between the hammer and the millstone. After the hammer-sieve clearance becomes larger, the hammer-millstone clearance still plays a crushing role, the higher crushing efficiency can be still kept, and the average output of the crusher can be increased. Due to the existence of the millstone, the rotating friction resistance of the material is increased, a thicker hammer can be adopted and the lateral surface of the hammer is made to generate friction with the millstone, so as to increase the available working area of the hammer, and greatly prolong the service life of the hammer.
