The shell of the hammer mill serves as the carrier for the entire machine and all its components, forming a robust fortress. The rotor transmits the operating power of the entire unit, composed of the main shaft, hammer plates, pin shafts, and hammer heads. It carries the crucial mission of the entire crushing process. The quality of the gravel is directly related to it. Although the hammer is a component of the rotor, it exists as a separate entity, serving as the primary crushing tool that directly contacts the material and requires steel casting. The liner is part of the crushing process. The equipment utilizes the stage of crushing materials.

Crusher Hammer Final Inspection: Final crushers should not have cracks or inclusions, sand inclusion, pores, shrinkage holes, shrinkage, lack of material, etc. Casting defects; gates, vertical pipes, flash burrs, and adherent sand should be cleaned thoroughly. After heat treatment, there should be no cracks or slag. The bolts on the crusher protective blocks must be securely connected, and the hard alloy on the crusher hammer handle must also be connected. The composite hammer head should be checked for cracks (double water quenching composite hammer head) to prevent cracking and falling off during use. The handle of the composite hammer head must be metallurgically bonded to prevent cracking or damage during use, to avoid significant losses.

The quality and structural design of the hammer: The structure and geometric shape of the hammer in the hammer crusher have a significant impact on its microstructure and mechanical properties. In terms of thickness, the larger the size of the hammer, the more pronounced the impact. Analysis reveals the failure modes of crushers made from different materials. The main cause of the hammer head's cracking is the presence of varying degrees of defects on the surface. In such defects, the hammer crusher will break during the initial operation.

The parameters of the hammer crusher: The appearance of parameters on the hammer of the hammer crusher will also affect its lifespan, with speed and rotor power being the main factors. It also influences the production efficiency of the crusher and directly impacts the hardening degree of the hammer under impact. Here, the better the hardening degree of the hammer crusher, the longer its lifespan; high manganese steel hammer heads, bimetallic crusher heads, and dual-liquid composite synthetic crusher heads are selected based on the crushing parameters of the hammer crusher.
