The service life of the hammer blade is related to the material of the hammer blade itself, the type of crushed material, etc. The material of the hammer blade is the most important factor affecting its lifespan. Hammer blades on the market are roughly divided into three categories: ordinary hammer blades, tungsten carbide spray welded hammer blades, and tungsten carbide fusion welded hammer blades.
Among them, as long as the ordinary hammer piece is a heat-treated hammer piece, or simply a 65Mn steel hammer piece is used, the price of this type of hammer piece is relatively cheap, but the corresponding service life is also shorter.
Tungsten carbide spray welding hammers are widely used in the market, using oxyacetylene spray welding technology to spray weld tungsten carbide powder onto the hammer substrate, and then heat treat the hammer to produce the final product. However, due to the harsh production environment and the influence of tungsten carbide welding wire quality, the quality of the final tungsten carbide hammer is also uneven, often accompanied by defects such as pores and inclusions in the weld layer, seriously affecting its service life. Especially when slightly harder materials are broken, it is easy to cause the weld layer to collapse. In addition, the production process is accompanied by a large amount of dust and harmful gases, which cannot achieve automation, and the prospects are not very promising.
HMT's tungsten carbide fusion welding hammers adopts plasma welding cladding technology, which deposits a layer of hard alloy particles on the hammer substrate, achieving almost the same thickness between the hammer substrate and the hard alloy welding layer. At the same time, each hard alloy particle has a multi-directional cutting edge, greatly enhancing the shear performance of the hammer. HMT's hard alloy fusion welded hammer pieces have excellent performance, with superior wear resistance, service life, impact resistance, and crushing efficiency compared to tungsten carbide spray welded hammer pieces. Moreover, the production process can be automated and environmentally friendly, making it a trend in modern hammer piece production.
The crushing of materials also has a significant impact on the service life of hammers, and using different hammers to crush different materials can greatly improve crushing efficiency. Some materials have high hardness, so the impact force on the hammer is also very strong. For example, when bamboo feed and tungsten carbide spray welding hammer are broken, the weld layer is prone to collapse. For materials with significant wear, the length of the wear-resistant layer should be increased by 100mm, such as grain husk feed. There is also the category of crushed wood blocks, which have a high impact force and wear, and tungsten carbide spray welding hammers cannot be used at all. For ordinary hammers, their service life is relatively short. For the crushing of such materials, HMT's hard alloy fusion welding hammers can meet the requirements very well. After practical use by a manufacturer of crushed wood blocks, it has been proven that HMT's hard alloy fusion welding hammers can meet the requirements very well. In addition, the moisture content of corn also has a significant impact on crushing efficiency. When the moisture content is high, the wear of the hammer is relatively large and the service life is shorter.
