How to Tell the Quality of Industrial Shredder Blades

1. Choose A Suitable Material for Industrial Shredder Blades

Industrial shredder blades are generally divided into 9CrSi, Cr12MoV, and SKD-11 from the material, of which 9CrSi is alloy tool steel. This material has high hardness and good wear resistance, but the brittleness is greater. It is suitable for rubber, fiber, paper, and other soft materials. Cr12MoV and SKD-11 are cold-work die steels. These two materials have similar properties, strong wear resistance and impact resistance, and are suitable for shredding wood, waste furniture, plastics with high hardness, etc.

2. Production Process of Industrial Shredder Blades

Whether the blank is forged or not, only the blades created by this technology allow the density of the steel atoms to be more tightly bonded. And a good blade is also very accurate in the accuracy of the processing equipment; usually speaking, it must be within the tolerance range of the blade.

For wire EDM, it is necessary to ensure the perpendicularity between the plane and the blade edge.

Inserts that are heat-treated during machining tend to be more durable, which keeps their hardness uniform and ensures a longer service life. Not only that, but the accuracy of the equipment must also be strictly audited.

3. Design Suitable Sizes of Industrial Shredder Blades

We know that the blade edge angle of the shredder tool can be adjusted and converted, usually between 19-23 degrees, so we can choose to adjust it according to the needs of different cutting materials in the cutting process, but the smaller and sharper the angle in the selection process, the better the cutting effect, but its defects reduce the service life of the tool in this way, which will also be a combination of advantages and disadvantages.

What should we do with the shredder-stuck material？

Customers often ask what to do with the shredder blade hanging; in fact, it is related to the tool size, shape design, and tool clearance.

The plastic material is relatively light, so the user will always see the shredder knife under the material hanging in the production process. When this kind of question is presented, there is no need to mind, only need to adjust the gap between the knives to solve this problem.

When the knife of the shredder presents the phenomenon of hanging material, perhaps because the gap between the shredder motor knife and the fixed knife is too large, it is only necessary to debug the gap between the shredder knife, the effect of the fixed knife of the shredder is not only to carry out secondary shredding, the fixed knife of the shredder can also avoid the material from falling from the gap between the shredder box and the blade, and can remove the mixed materials between the knife and the knife, help to remove the material hanging on the knife, to ensure the complete shredding of the material in the shredder.
