Second-generation vertical impact crusher’s hammer only a pair of back side using the second, counter-wear plate can not adjust the gap, while the third generation of vertical impact crusher hammer down side can turn around four directions can be used and each radial direction can move 30 ~ 50 mm, compared with the second generation of vertical impact crusher hammer to adjust the number by at least 10 times, and the back plate wear after the gap can be guaranteed.
Thus, in theory, increase life expectancy board hammer 10 times, that a pair of hammer can be broken clinker 10 to 15 tons, but taking into account other factors, at least 3 to 5 million tons of crushing the affirmative. And through the composite manufacturing process, high resistance to abrasion-resistant material sufficient to ensure the effective utilization rate of 70% to 80%. Thus, although this new variant of the hammer price increased slightly, but its overall efficiency and economic use is better.
The successful development of the third-generation impact crusher also known as LFP Vertical Impact Crusher , thanks to the concept of updating the first and knowledge refinement. Generally always thought that the life of the hammer to raise stand-alone, or only in the material seems to be an issue, in fact, this understanding is not complete. In general, the hammer and hammer wear life are inextricably linked, but they are different between the two, wear-resistant for materials, life is for the use of terms.
In other words, as long as the hammer and the back plate to ensure that the gap between the maintained at a reasonable range, when the longer the duration of this state, the hammer’s life will be longer. Therefore, if by special design makes use of the hammer always state that will extend the life of the hammer.
Changes in the concept of design guidelines to bring the changes we made significant improvements to its structure and to achieve clearance between the hammer and adjustable back plate. Specific approach is the vertical impact crusher rotor top of the trench along the radial opening number, mounted on the plate hammer on the hammer and the gap between the back plate mounted on the rotor by a group of tabs on the control, if hammer wear, or back plate to be worn, then according to the size of wear on the rotor can adjust the thickness of the plate and reduce the number to continue to hammer with a reasonable gap between the back plate, and give full play an effective wear-resistant materials utilization, so not only ensures the product of fineness, but also greatly extended hammer life.
