In resource recycling and modern industrial production systems, granulation processing is a key link between raw material processing and finished product molding, widely used in various fields such as plastic recycling, rubber regeneration, feed processing, and organic fertilizer production. As the core executing component of granulation equipment, the cutting accuracy, wear resistance, and adaptability of granulator blades directly determine granulation efficiency, product quality, and equipment operation stability. They become the core support to ensure the efficient operation of various granulation production lines and play an irreplaceable role in promoting resource recycling and industrial quality and efficiency improvement.
The excellent performance of granulator blades is first built on rigorous material selection. Due to the continuous impact load, material friction, and possible high temperature that blades need to withstand during operation, their materials must have excellent comprehensive mechanical properties. High speed tool steel has become an ideal choice for many conventional application scenarios due to its good red hardness, wear resistance, and appropriate toughness; For extreme working conditions involving reinforced fillers or high hardness materials, blades with embedded hard alloy tips or using powder metallurgy high-speed steel exhibit a longer lifespan; In hygiene sensitive fields such as food or medicine, martensitic stainless steel or special coating treatment not only ensures corrosion resistance and cleanliness, but also provides necessary cutting performance. The selection of each material is a delicate balance between material characteristics, production efficiency, and economic cost, with the core being to maintain the geometric integrity and sharpness of the cutting edge under extreme working conditions.
High quality material selection and precise machining processes are the foundation for achieving excellent performance in Granulator Blades. According to the characteristics of different processing materials, granulator blades have formed a diversified material system, among which D2 type material occupies the main share of the global market due to its excellent wear resistance and stability. In addition, various material options have been derived for different working conditions, such as high-speed steel, hard alloy steel, stainless steel, etc. High speed steel blades have sharp edges, are easy to polish, and are suitable for granulation of soft plastics and other materials; Hard alloy inserts, with their high-strength cutting edges, can handle cutting of hard materials such as engineering plastics and reinforced nylon; Stainless steel blades can avoid rust pollution and are suitable for processing scenarios with high material purity requirements. In terms of processing technology, the blade needs to go through a strict heat treatment process to ensure that the hardness is controlled within a reasonable range. At the same time, precision CNC machining is used to ensure that the edge tolerance is extremely small, so that each blade is on the same axis track, thereby improving the uniformity of cutting particles.
The design and geometric configuration of the blade directly determine the efficiency and particle quality of the granulation process. The common rotating cutter and bottom cutter form a cutting system, and the design of the blade angle, rake angle, rake angle, and blade sharpness needs to accurately match the characteristics of the processed material. For tough materials, sharp edges and reasonable angles help achieve clean cutting, reducing wire drawing or powdering; For brittle materials, it is necessary to consider the stress during crushing and control the particle size distribution. The installation and positioning accuracy of the blade, including rotational dynamic balance, positioning accuracy on the disc, and gap adjustment with the bottom blade, is the technical key to ensuring stable cutting action, uniform particle size, and avoiding abnormal wear or vibration noise. Micro scale gap adjustment often leads to significant differences in particle quality and production stability.
Wide adaptability to various scenarios allows Granulator Blades to deeply integrate into multiple industrial and environmental fields. In the field of plastic recycling, it is the core component of waste plastic recycling and processing, which can crush and cut various types of waste plastic products into uniform particles, achieving resource regeneration; In the rubber recycling industry, waste rubber can be accurately crushed to provide raw materials for the secondary processing of rubber products; In the field of agriculture, whether it is the granulation of organic waste such as livestock manure and straw in organic fertilizer production, or the granulation of raw materials in feed processing, the support of granulator blades is indispensable. In addition, it is widely used in emerging fields such as the resource utilization of kitchen waste and the processing of biofuels. With the development of these industries, its application scenarios are still expanding.
