Hammer Mill

The hammer mills manufactured by Formats Construction Machinery are suitable for processing of medium hardness rock and ore like limestone, marble, Iron ore, granite, etc. The moisture of the material should be less than 20%.

Since many years, hammer mills are used in various industries and nowadays often play an important role in production facilities. The most hammer mill grinders are used not only in Mining industry, but also in other industries, hammer mills are found.

The Hammer Mill grinds by the collisions between high-speed hammer and materials. When Hammer Mill works, the motor drives the main shaft through V-belts to rotate. The capacity of a hammer mill is about 20 to 100 ton / H. It has features of simple structure, high reduction ration, high efficiency etc.

Structure and working principle:

This type of hammer mill is consisted by the steel frame, rotor, blow bar, grizzly screen, etc. The upper part and lower part of steel frame are firmly welded, while other parts are connected by the bolts. With the high manganese steel liner which is easily changed if it is worn out, the steel frame is well protected. There are sets of hammers with exactly the same weight installed on the main shaft, and tightened by high-strength bolts.
When it works, the motor drives the main shaft and rotors on it to rotate through V-belts. The bulk of materials will be fed into crushing cavity through inlet, and get hitten and crushed by rapidly moving hammer. Then the stone small enough to be discharged through the grizzly screen will be collected as final products, the rest would be stucked in the crushing cavity and be crushed again and again. To avoid clogging, moisture content of the material should be below 20%.
