Hammer crusher is a common crushing equipment, SBM machine customers visiting every day , there are a considerable number of professionals , many people ask about the hammer to break the rotor design problem , and today take this opportunity to introduce under the hammer to break the rotor is how to design and let everyone know how the rotor design is reasonable.
First, we need to know , hammer crusher for cement , chemical, electric power, metallurgy and other industrial sectors crushing medium hardness materials , such as limestone , slag , coke , coal and other materials in the debris , crushing operations . Hammer crusher rotor by a hammer , spindle and bearing , pin, hammer holder and dial components.
Second, determine the location of the pin hole hammerAlthough the rotor hammer crusher rotor balance reached a requirement, but if the hammer hanging incorrectly , that position does not pin hole will cause the material with the impact hammer on the pin , spindle and bearing an impact reaction force . Therefore, in order to make the operation of the crusher , hammer pin is not generated in the reaction , must be in equilibrium under the impact hammer . The so-called equilibrium, that is, after the material impact hammer , hanging pin does not have an impact on the reaction force . Essentially pin hole location is the right choice .
Third, the determination of the quality of hammerhead
Hammerhead is the most critical part of hammer crusher , hammer and size will directly affect the quality of the crushing effect . If the quality of the hammer is too small, the broken material can not meet the requirements once ; if the hammer mass is too large, the excessive consumption of wasted effort , nor economical . Entire rotor shaft is supported by parts of the spindle and mounted on the side wall of the flow rack bearing . When an impact force generated by the work of the breaker plate are borne by the shaft , thus requiring a material having a high spindle...
