I plant the production of high chrome hammer, adding a lot based on the original production of precious and rare alloys can withstand harsh abrasive wear. Modification using a variety of alloys, niobium, vanadium and other precious elements of strengthening the matrix. Vacuum casting, directional solidification, grain refinement greatly eliminate casting defects radically. Hammer crusher work is very high spindle speed of operation, so the centrifugal force generated by hammer crusher is great, which need to ensure consistency in the quality crusher hammer, but the quality of the hammer crusher hammer actual production difficult to achieve consistency requirements, which require human conduct crusher hammer weight. The hammer crusher is wearing parts, change frequently, to be replaced every two months on average. Here Li Xin equipment Limited for the majority of users to introduce two more practical approach, good customer response in the test results.
