Choosing good hammer head to increase hammer crusher efficiency
2014-08-12
Do you know the working principle of hammer crusher? The motor drives the rotor of the hammer crusher rotate at a high speed through the belt. The materials are sent into the entrance of the crusher. They are crushed by the high speed hammer from blowing, impacting, cutting, grinding. Below the rotor, there are sieves, the little size products among the crushing products can be discharged through the sieve. The large size products are brought back to the crushed area by the hammer from blowing and grinding until they reached the required size. At last, they are discharged through sieve. If we increase the crushing impact of hammer head to material block, the crushing efficiency of hammer crusher can be greatly improved.
Hammer head is the main working part in hammer crusher, is also a main vulnerable parts. The appropriate selection of hammer head has a great influence in crusher crushing efficiency. We have to consider many factors when select the material, and let Juxin expert share his experience with you.
Firstly, the material characteristics. When selecting the hammer head material, we have to get a good understanding for the crushed material composition, hardness, size, sharpness and moisture content etc. On the basis, consider the hammer head size, crusher rotor speed to select the appropriate hammer head.
Secondly, the impulse loads. The impulse load is the key factor to select the hammer head material. Usually the larger the crushed material, the hammer head toughness needs higher. The big materials generally 800-1000 - mm in diameter, hammer head has to undertake big impulse load, and the alloying of high manganese steel is the good choice. For small and medium-sized hammer head, its weight is between 5 and 15 kg, and using high manganese steel can't display the characteristics of the strain hardening. Under the condition of the material particle size is not big, if the crushed material is not large, should choose carbon chromium nickel molybdenum alloy steel hammer head and high chromium cast iron material.
Above all, hammer head is an important part in hammer crusher, it also can be determined the life of the hammer crusher, good hammer crusher is equally to long working life, so users should learn to choose good and suitable hammer head for their hammer crusher.
