Hammer crushers are the most popular stone crushers in the market . It is also called hammer mill. It has high production capacity, low energy consumption, simple structure, reliable quality, easy maintenance, etc.
The hammer head is the most important working part of the hammer crusher. The quality, shape and material of the hammer head determine the production capacity of the hammer crusher. The kinetic energy of the hammer head is proportional to the weight of the hammer head. The heavier the hammer head, the greater the kinetic energy and the higher the crushing efficiency. The weight of the head is complete, the minimum hammer head is 15 kg, and the maximum hammer head can reach 298 kg. Various hammer head weights can be customized according to customer needs. The hammer head is made of new high-quality multi-element high-chromium-manganese steel composite casting, and its service life is Several times the general hammer head.
The rotor is the main working part of the hammer crusher. The rotor consists of a main shaft, a hammer disc, a pin shaft, a hammer head, etc. There are evenly distributed pin holes on the disc, and the hammer head is suspended by a pin shaft. In order to prevent the disc and the hammer head The axial movement of the shaft is fixed with locking nuts at both ends of the pin shaft. The rotor is supported on two rolling bearings, the bearings are fixed on the support of the lower body by bolts, and two positioning pins are fixed on the center distance of the bearings. In order to make the rotor store a certain kinetic energy during movement, to reduce the peak load of the motor and reduce the wear of the hammer head, a flywheel is specially installed at one end of the main shaft. The main components of the rotor are described in detail below.
The main shaft is the most important part of the hammer crusher supporting the rotor. The weight and impact force of the rotor and the hammer head are all borne by it. Therefore, the material of the main shaft needs to have high toughness and strength. The material of the main shaft is made of high-quality alloy steel. Ultrasonic flaw detection to process for quenching and tempering. 2.2 The hammer disc of the hammer disc hammer crusher is used to suspend the hammer head. During the operation of the hammer crusher, the hammer disc will inevitably be impacted and rubbed by the ore, so the hammer disc should be required to have a certain resistance. Abrasiveness, the hammer disc and hammer hole use high-manganese steel carburizing heat treatment to improve its wear resistance.
