Hammer mill crusher is one of the main machines used in such industrial departments as metallurgy, building material, chemistry and hydropower for the medium and fine crushing of limestone, coal and other crisp materials with below medium hardness. Hammer mill crusher has many features such as big crushing ratio, high production capacity and even product granularity. Hammer crusher is a single-stage crusher machine that is able to directly crush the materials whose biggest granularity is 600-1800mm to 25mm or even below.

Hammer mill crusher is mainly composed of crusher box, rotor, hammers, impact lining boards and screen plate. Among them, the main working part is the rotor with hammers. The rotor is mainly composed of principal axis, disk, pin roll and hammers. Hammer crusher has advanced structure, reliable performance, balanced working condition and low energy consumption. According to the working principle of hammer mill crusher, it can be divided into reversible hammer crusher and irreversible hammer crusher. The rotor of the former is reversible, so that it is mainly used for fine crushing, and the rotor of the latter is irreversible, and it is mainly used for medium crushing.
A. According to the numbers of the rotor, hammer mill crusher can be divided into single-rotor hammer crusher and double-rotor hammer crusher. The main case of the single-rotor hammer crusher is composed of upper and lower pats which are made of steel plate and that are connected with bolts.
B. According to the rotational direction of the rotor, hammer mill crusher can be divided into reversible type and irreversible type.
C. According to the line numbers of the hammers, hammer mill crusher can be divided into single-line type and multi-line type.
D. According to the connection method of the hammers on the rotor, hammer mill crusher can be divided into fixed type and movable type, and the fixed hammer crusher is mainly used for the fine crushing and power grinding of soft materials.
E. Other types of hammer mill crushers include sealed hammer crusher, heavy hammer crusher and ring hammer crusher.
