Application

The european type coarse powder hammer mill is widely used to crush mineral ores mediumly or finely with compressive stress below 320Mpa in industries like metallurgy, mining, chemicals, cement, construction, refractory, ceremic, etc.

Features:

①. big crushing ratio and large capacity;
②. Low consumption and even granule;
③ simple design and compact structure;
④ modest investment and easy management.

Structure and working principle:

This european type coarse powder 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%.
