Single-stage Hammer Crusher

Hammer crusher has various types and can be classified into single rotor hammer crusher and double rotor hammer crusher according to the number of rotor, and be classified into reversible hammer crusher and irreversible hammer crusher in accordance with the direction of rotation of rotor.

Hammer crusher machine is suitable for crushing all kinds of medium hard materials with weak corrosivity. The materials to be crushed by this machine should be no more than 100MPa in compression strength, and less than 15% in water content rate. It can be used for crushing coal, salt, chalk, gypsum, tile and limestone, and it can also be used for crushing fiber structure, elastic mood pieces, paper or crushing the asbestos cement for recycling asbestos fiber. In addition, the hammering machine can be used not only in crushing production line and sand making production line, but in the ore dressing line for replacing cone crusher.

The hammer crusher is mainly composed by the box, rotor, hammer, impacting lining board and the screening bar.

Working Principle of Hammer Mill Crusher:

The electric motor drives the rotor to rotate at high speed in the crushing chamber. The materials are fed into the machine from the upper material feeding mouth and are crushed under the effect of impacting, hitting, cutting and grinding of the hammer moving at high rate. Under the rotor, there is screening bar. The crushed materials whose granularity is smaller than the size of the screen hole will be discharged from the screening bar; and the coarse materials larger than the size of the screen hole will remain on the screening bar to be hit and ground again by the hammer and finally they are all discharged out of the machine from the screening bar.

Types of Hammer Mill:

The common hammer mill includes single-rotor type and double-rotor type. According to the arrangement of the hammer on the rotary table, it can also be divided into single-row hammer mill and multi-row hammer mill, and the rotary direction of the rotor includes reversible type and irreversible type. In addition, there is still simple type hammer mill such as ring hammer mill crusher. Among them, the most widely used is single-rotor single-row hammer mill.

Characteristics of Hammer Crusher Machine:

(1) The working hammer adopts new technology so that it is anti-abrasion and anti-impact.

(2) The granularity of the products can be adjusted according to the customers’ requirements.

(3) The structure of the whole machine is compacted, thus solving the problem of powder dust pollution in the crushing workshop and dust leakage of the machine.

(4) The machine has many advantages such as beautiful designing model, compacted structure, less easy-wearing parts and convenient repair, so that it is an updated product.
