Shredder blades as an important part of the shredder, if the use of wear or blunt, it is necessary to timely repair or replacement, shredder cutter with blunt will affect the entire device after the shredding effect has been To timely maintenance, in peacetime also have to do the inspection and maintenance of the shredder blade. Shredder manufacturers also need to come out from the price competition, turn to practice internal strength. Focus on product structure optimization, product quality improvement, core technology mastery and innovation, as well as the expansion of corporate brand influence. Of course, shredder business also needs to make a scientific estimate of the future IOI according to its own circumstances, to selectively invest and make a gradual transition. Motor can not be shredded over current operation, otherwise it will cause serious fever, causing local damage. Although this may have some short-term effects, the performance of the oil will be significantly reduced while the lubrication conditions of metal shredder bearings deteriorate. Lead to increased bearing wear a certain sense will shorten the bearing life. General selection of high toughness, hardness (slightly smaller than the hammer) made of grate material and its support frame. Castings are usually made of high manganese steel, but also forged. Each grate with stainless steel welding rod welded to the grate rack, forming a whole, to improve its stability. Cut some original liner, the appropriate reduction in the width of the liner to facilitate the adjustment of the grate bar rack. So that the entire double-shaft shredder production line in a completely power-off state, then the shredder blade material in a timely manner to remove, the conveyor belt material to be unloaded out, the material under the mouth of the finished product directly into the finished bag.
