European version of rough grinding mill is widely used in metallurgy, mining, chemical, cement, coal, dry stone, construction, sand, refractories and ceramic industrial and mining enterprises, engaged in breaking and crushing the material in the operation. It is mainly suitable for crushing compression strength not higher than 320 MPa of various soft and hard ore. Product features: The production capacity, high crushing ratio. Low power consumption, uniform particle size; Mechanical structure is simple, compact and lightweight. Lower investment costs, management and convenient. Structure and working principle: The European version is mainly by coarse grinding casting, rotor, bearing the hammer and the bars and other components. Upper and lower case in two parts, welded together by a steel plate after cutting, the remaining parts bolted into one. Set with high manganese steel liner inside the case, to facilitate replacement of wom; Its array of rules installed on the spindle distribution of the hammer, hammer and rotary table and through the rotor shaft formed. Host through the motor, v-belt driven spindle, so that the rotor rotates, hammer by the centrifugal force generated by rotation around the stretch to, bulk materials from the feed inlet into the crushing chamber, the high-speed movement of the hammer will be crushed broken by passing the material under.
