Hammer Crusher/Stone Crusher/Sand maker/Quarry Crusher
Hammer crusher
The coarse 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 320MPa (MPa) of various soft and hard ore. European Type Coarse Hammer Mill Crusher Machine for Limestone 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.
Coarse grinding mill Performance and Features
1. High capacity, big crushing ratio;
2. Low power consumption, uniform granularity;
3. Mechanical structure is simple, easy to use;
4. Investment costs less, more Convenient Management.

Coarse Grinding Mill Working Principle:
The coarse grinding mill is mainly consist by the frame, rotor, impact plate, grate bars and other components. Machine frame is divided into two parts, it is welded by steel plate after cutting, the other parts are connected by bolts. There are high manganese alloy liner inside the frame, easy replacement after wearing; Several sets of hammer are installed on the main shaft, they are connected by high-strength bolts. The main machine is running by motor and v-belt, then led the rotor spinning, large material enter to the crushing cavity from feed pole, will be crushed repeatly by rotor and hammer, then the qualified final products.
The Coarse powder grinding mill casing, rotor, bearing the hammer and the grate 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 worn; 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.
