Hammer crusher is my factory technical personnel according to the activity of lime (lime) characteristics and crushing demands a machine specially designed. Through the feedback of practice of a few years of use and user repeatedly improved usability reached today ideal, namely fine aggregate ratio, less than 3mm accounted for more than 95%, high yield, 40-80 tons per hour, the models of rational structure, low failure rate of equipment. In addition, the hammer crusher not only can be used for crushing production line, sand production line, but also can replace the cone crusher in the mineral processing production line. The main working parts of hammer type crusher with a hammer (also known as hammer) rotor. The rotor comprises a main shaft, disc, a pin shaft and a hammer. The motor drives the rotor in the crushing cavity high speed rotation. Material from the upper mouth to feed into the machine, the high speed movement of the hammer blow, impact, shear, abrasive and grinding. The lower part of the rotor, with sieve plate, crushing material in less than sieve size fractions discharged through the sieve plate, coarse and resistance in the sieve plate is larger than the aperture size continues to be a hammer blow and grinding, and finally through the sieve plate discharge machine.
