Introduction to Hammer Crusher 

Hammer crusher makes use of the high-speed impact effect of the hammer, which can be used for processing the medium and fine crushing, and the hammer crusher has found its extensive application in the field of mine crushing and grinding. The hammer crusher is one of the main equipment for intermediate and fine crushing the brittle materials with less than intermediate such as limestone coal and the others used in metallurgy, building material, chemical and water - power industry, with a feature of big crushing ratio and product graininess.

Application of Hammer Crusher

The hammer crusher can be widely used for crushing the materials with the medium hardness and brittle features in the works of mining, cement, coal, metallurgy, building materials, roads, burning, etc, and the crushed materials are mainly including coal, salt, chalk, gypsum, brick, and limestone and so on, with the anti-pressure of less than 100Mpa and moisture of less than 15%.

Working Principle of Hammer Crusher

In the hammer mill machine, the motor drives the rotor to rotate at a high speed through the belt, and on the rotor there are series of hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed will crush them, the crushed products meeting the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushing area by the hammers for being re-crushed until they reached the required size.

Basic knowledge on Hammerhead

Hammer head is easy to wear, one side can be turned around again after wearing both sides. When replacing hammer head, we should weight them according to one of the hammer, and we should make quality of each group equal. Each of two queue of hammer and pin shaft of total quality should be less than 0.05 kg, which can ensure the smooth running of the rotor. Changing hammer should also be watched out, the examination of the crack cavity and sand holes shall not be used by the computer.

Hongxing Single Stage Hammer Crusher with High Quality

Single stage hammer crusher can crush the feed materials of graininess 1100mm into less than 20mm for one time, so the traditional double stage or three stage crushing can be changed into one stage crushing. Reversible hammer crusher with reversible rotor is used for fine crushing in general; non-reversible hammer crusher with non-reversible rotor is used for intermediate crushing. Single stage hammer crusher is non-reversible. Ordinary hammer crusher is composed of frame, rotor, grate bar, impact plate and adjustment unit; single hammer crusher is composed of frame, rotor, feeding roll, grate bar, hydraulic opening unit and foundation.
