1. Coarse Crushing for Sand Making, 0-3 Mm Coarse Grinding Mill
Product Description
Coarse grinding mill:
1. Hammer crusher for industries of metallurgy,mining, chemistry, cement, construction, refractory
materials and ceramics.
2. High capacity, 10-100t/h.
3. Uniform particle size
Application of coarse grinding mill:
Coarse grinding mill is engaging in crushing various rocks and stones with comprehensive strength not
higher than 320 MPa into coarse powder and small particles, it is widely used in metallurgy, mining,
chemical, cement, coal, sand-making, coal gangue, construction, refractory materials and ceramic
industries.
Working principle of coarse grinding mill
Coarse vertical grinding mill mainly consists of frame, rotor, support iron and grate bars. The frame is
divided into two parts: upper part and lower part, which are welded by steel plates after being cut. Liners
made of high manganese steels within the frame can be replaced after being worn out. The rotors consist
of turn plates, pin shafts, and hammers which are grouped regularly in the main shaft. The main unit
drives the main shaft through the motor and triangle belts, which, in turn, rotates the rollers. Large
materials entering the crusher through the feed inlet are firstly crushed by the high-speed hammers, and
then thrown fiercely to the support iron for further crushing. Qualified materials crushed will be screened
out and exit from the gap of the grate bars while the unqualified will be left in the crushing cavity to be
further hammered and ground until reach the standard size. The size of the final product can be adjusted
by changing the grate bars. The gap between the rotors and the grate bars can also be adjusted
according to different requirement. To avoid the plugging of the crusher, the proportion of water for the
crushing materials is no more than 20%.
The features of coarse grinding mill
1. Uniform particle size with high crushing and crushing ratio;
2. High capacity and low power consumption;
3. Simple structure; Easy operation;
4. Low investment and environmantal-friendly.
