Why is it not recommended to use high chromium alloy hammer head for large stone hammer crusher?
After continuous market research and actual production demonstration, it can be concluded that the hammer crusher series products produced by Shandong Sanxiang Heavy Industry Co., LTD., the failure rate of the models from the middle model to the lower model in the use of high chromium alloy hammer head is significantly lower than that of the larger model. After repeated argumentation, we believe that it may be caused by the following reasons, and the solutions that can be taken, the following is a simple discussion with you.

First of all: the large hammer crusher is relatively more kinetic energy of the rotor, and the impact force is greater. If you enter the larger material to be broken, the first strike of the alloy hammer head is not successful, it will be hit by the instant rebound behind the hammer sleeve, there is a chance of damage to the hammer head, there will be a broken nose or fracture in the alloy joint. If the quality of the high chromium alloy hammer at this time is not enough, it will hurt the machine, and the heavy will need to be overhauled.
Second: the larger the inner hall of the machine, the heavier the corresponding hammer weight will be. In the design, the hammer disk will be thicker, the hammer shaft will be thicker in order to deal with the weight of the hammer head, but now a common phenomenon is that the alloy hammer head used in the large hammer crusher is increased in the weight at the same time, the hammer handle is also lengthened accordingly. This increases the kinetic energy of the alloy hammer in the process of high-speed rotation and the reaction force from the material to be broken, and it is easy to be hurt. This is a good way to avoid this on the impact crusher, because its hammer head can be rotated 360 degrees, and in the case of a hit, it can be quickly turned over and then broken the material.
Third: Shandong Sanxiang stone crusher machine manufacturer in view of the problems encountered in the current actual use, is actively improving the new compound hammer, trying to avoid the shortcomings of the traditional hammer, combined with the advantages of the hammer crusher product series, and strive to make the new product more scientific and reasonable.

Fourth: Continue to increase the research and development of wear-resistant parts of the crusher. Although the current high chromium alloy hammer head in terms of wear resistance compared to high manganese steel and forging materials on a step, but it is undeniable that in terms of failure rate is still not as good as the latter two. Many hammer crusher users in the purchase of a suitable high chromium alloy hammer, many choose to use a lower failure rate of high manganese steel or forging material hammer. If the wear cost of the material to be crushed is low, it is good, if it is slightly higher, it is necessary to often replace the hammer, which is laborious and affects the production efficiency to a certain extent.
Fifth: In the final analysis, in order to solve some problems encountered at the current stage of high chromium alloy hammer, or to the product quality to say, only continuous improvement and improvement of high chromium alloy hammer casting process and product quality, coupled with scientific and reasonable structural design scheme, in order to really solve some problems encountered in the actual production of hammer crusher.
Sixth: Although there are still some deficiencies in the high chromium alloy crusher hammer, the future development trend must be the stage for its display, which will not be affected by some defects. On the road of pursuing a molding stone crushing production line, we still have a long way to go, although we have made some achievements. Only by facing up to some of the objective conditions in front of us can we be encouraged to continue to strive forward.
In summary: why Shandong Sanxiang Heavy machinery's plant of large hammer crusher is not recommended to use high chromium alloy hammer, there must be a reason, but the future development trend is that there will be more users choose to use it, because its wear resistance than high manganese steel or forging material is not a little stronger. In the next step, Shandong Sanxiang rock crisher machine factory will continue to increase research efforts on wear-resistant materials, and strive to come up with better products to return the majority of users.
