Coarse Grinding Mill

European Coarse Suspension Grinding Mill is in the absorption of domestic and foreign advanced technology, combined with the specific conditions of sand industry and the development of a new generation of counter type crusher.
Coarse Grinding Mill
European Coarse Grinding Mill absorbed the international counter-broken with the latest technology, giving its latest update of international advanced level of quality products. The rotor is the "heart" of the crusher, and it is also the most stringent part of the impact crusher, which plays a vital role in the work. Therefore, JPR has developed and produced a strong structure of the heavy rotor to obtain a higher moment of inertia. High wear resistant equipments and the best of the crushing chamber, making crushing machine of the extraordinary performance, is very suitable for smashing all kinds of soft and hard ores, the material of coarse crushing, crushing, fine crushing.

Working principle of European Coarse Grinding Mill

European Coarse 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 turnplates, 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%.

Features of European Coarse Suspension Grinding Mill :
1. Uniform particle size with high crushing and crushing ratio;
2. High capacity and low power consumption;
3. Simple structure; Easy operation;
