Blade Standards on Shredders

The shredder blade is one of the most important parts of the shredder. The shredder chassis includes the chassis, shaft, and blades, and is one of the main parts of the shredder. The shredder chassis is widely used in metal, circuit boards, plastics, waste rubber, wood and other large-volume wastes, and is one of the most important parts of the shredder. The quality of the shredder blade directly affects the processing cycle of the machine for waste. According to the classification of shredders, shredder blades are divided into single-axis shredder blades and multi-axis shredder blades. As an important shredder blade. According to the shredder structure classification, shredder blades can be divided into single-axis shredder blades, multi-axis shredder blades (including double-axis shredder blades and four-axis shredder blades). Used to crush, tear and squeeze to reduce the size of the material, this shredder blade is widely used in the crushing of waste plastics, waste rubber, wood and other large-volume wastes.

According to the design of each company, the shredder is installed on a double-axis or four-axis shredder. It can be generally divided into single-claw shredder blades, 3-claw shredder blades, 8-claw shredder blades, 12-claw shredder blades, etc., which are used to crush, tear and squeeze to reduce the size of materials. This type of shredder blade is widely used in the crushing of waste plastics (plastic shredder manufacturers), waste rubber, wood and other large-volume waste.

The common specifications of double-axis or multi-axis shredder blades are 300, 350, 400, 450, 500 and 600. However, because the requirements of manufacturers for thickness, number of claws and claw depth are different, there is basically no standard stock for double-axis shredder blades. Customers need to make their own requirements to Daqian Heavy Industry for customization. According to different materials and quantities, the processing cycle is usually within 7-15 days.

Shredder blade specifications:

Standard shredder blades are available in stock, and non-standard knives can be customized according to customer drawings. Sample processing is supported.

The shredder chassis is the most critical part that directly affects the noise and production efficiency during the machine processing. The most critical part is the shredder blade, which directly affects the processing cycle of the machine for waste. According to the classification of shredders, shredder blades are divided into single-axis shredder blades and multi-axis shredder blades. As an important shredder blade. According to the shredder structure classification, shredder blades can be divided into single-axis shredder blades, multi-axis shredder blades (including double-axis shredder blades and four-axis shredder blades).

Classification of shredder blade materials:

The materials used to manufacture shredder blades are generally 9CrSi, Cr12MoV, and SKD-11. 9CrSi is an alloy tool steel. This material has high hardness and good wear resistance, but it is brittle and suitable for softer waste materials such as rubber, fiber, and paper. Cr12MoV and SKD-11 are cold-working die steels. These two materials have similar properties and are highly wear-resistant and impact-resistant. They are suitable for shredding wood, waste furniture, and high-hardness plastics.

Common materials for shredder blades are: 42CrMo, W5SiCr, 6CrW2Si, Cr12MoV, etc. Different materials are selected according to different processing objects!

Common materials in the plastics industry: 42CrMo, W5SiCr, SKD-11

Common materials in the metal industry: 6CrW2Si, Cr12MoV, LD, H13, SKD-11, D2

Common materials in the wood industry: W5SiCr, 6CrW2Si, SKH, SKD-11

Heat treatment: HRC55-57
