Hammer crusher machine has simple structure and is usually used for crushing materials of medium hardness and crisp materials and it has wide application in stone production line and sand making production line. Even though hammer mill crusher is not good as jaw crusher machine in production capacity, it has larger crushing ratio, so that its crushing function is more excellent. Hammer crusher crushes materials by relying on the hitting of hammer part on materials, for this reason, there will be no over-crushing particles, so that the energy can be made full use and energy consumption is reduced. In addition, hammering machine also has such advantages as simple structure, light weight and simple and convenient maintenance. The models of hammer mill crusher are various, and the discharging granularity is controlled by the grate bar device, so that the product granularity can be easily controlled.
How can a hammer crusher machine be improved? Here the experts of Hongxing Machinery will talk about this question with all the customers.
1. Change the monolithic construction of the upper part frame to split type. With this structure, the maintenance of rotor will be convenient, and it only needs to remove the left split part to hoist out the rotor. When changing the structure, pay attention to rift the upper rack. When welding a pair of flanges, it is required to remove the stress to ensure the assembly performance of the whole machine. Change the radian of the grate bar frame from R520 to R510 to reduce the gap between grate bar to hammers, which is also convenient for adjusting the grate bar frame. When hammers are abraded, the grate bar will have sufficient adjusting space.
2. Lengthen the grate bar frame to 160mm and arrange four more grate bars to increase the acting area of hammer mill crusher and for the products with qualified granularity to be timely discharged from the crushing chamber, reduce the over crushing particles and lower the load of the hammering machine, thus improving its production capacity.
3. Build up welding and reinforce the grate bar frame and grate bar. After installing the grate bar frame and grate bar, using wear-resisting hardfacing electrode to build up welding and reinforce the grate bar frame, and the surfacing height of the quick-wear working surface should be as high as 5mm. At the same time, welding and fixing the grate bar onto the grate bar fame can prevent the grate bar frame from deforming, and if the grate bar scatters, the grate bar frame can have the functions of fastening and protection. Such improvement can greatly extend the service life of the grate bar fame and grate bar and reduce the material consumption.
4. Carry out static and dynamic equilibrium test to the rotor of hammer mill and install hitting balance hammers. Such improvement is an important approach to solve the vibration of hammer crusher. Integrate the foundation of this crusher machine with the foundation of other driving motors and use concrete for masonry to increase its resistance to shock and prevent vibration from damaging the foundation, thus ensuring the using performance of this crushing equipment.
