HPGR hard alloy column nails ensure wear resistance during normal use, with continuous nail, corner, and nail dropping phenomena. However, the premise is to ensure compliance with the usage specifications, which is determined by the mechanical properties of the column nails. Hard alloy column nails have a hardness of around HRA87 and high wear resistance, but their shear resistance is poor. They are prone to fracture or accelerate wear under the impact of hard objects and large materials.
On the other hand, the column nails are sensitive to metal foreign objects, so the material fed into the roller press should be thoroughly removed of iron as much as possible. In addition to setting iron removers on the feeding belt, it is also necessary to install metal detectors on the feeding belt in the system. Moreover, during the production process, it is necessary to ensure that the metal detector and the feeding system are interlocked smoothly and react quickly, in order to timely eliminate mixed metal foreign objects in the materials.
Although hard alloy nails have ultra-high wear resistance, under the impact of large materials, they will inevitably fracture, fall off corners, and wear faster. Therefore, it is equally necessary to control the impact type of large materials. Once the hard alloy nails break or fall off corners, they should be replaced in a timely manner. This phenomenon is not due to quality defects in the hard alloy nails themselves. The user should replace them in a timely manner and strictly avoid the impact of large materials.
