Coarse Grinding Mill

introduction

Coarse Powder Hammer Mill is widely used in mining, building materials, chemical industry, metallurgy, cement, ceramic, refractory industry and so on. The Coarse Powder Hammer Mill is suitable for secondary and fine crushing of all kinds of rocks with compressive strength less than 320 MPa.


advantage

The Coarse Powder Hammer Mill is of high capacity, high crushing ratio, simple structure, uniform output granularity as well as low electricity consumption, and is easy to maintain and operate. The moisture of the raw material should be less than 10% - 15% to avoid the blocking of material during the crushing process.

working principle

The Coarse Powder Hammer Mill mainly includes case, rotor, iron bearing, grate bars and other components. There are two parts in case: the upper one and lower one which are welded after cutting. The remaining parts are connected by bolts. Inside the case, there is high manganese steel liner which can be replaced after wear and bear. The Coarse Powder Hammer Mill is installed on an array of spindles which forms the rotor together with rotary table and axis. The rotor rotates through motor and V-belt driven spindle. The hammer streths around as the centrifugal force generated by rotation, in that way, bulk materials feed into the crushing chamber and are crushed by the high-speed movement. The standard stones pass from the grate bars below and for those not standard will again be crushed in the case till they can pass from the grate.
