How to identify the hardness and wear resistance of the tooth shredder of the tire shredder？

The tire shredder blade is one of the most important accessories for a tire shredder.The hardness and wear resistance of the blade determines the effect and extent of material shredding.

So, how to distinguish the hardness and wear resistance of the tooth shredder of the tire shredder?

1. High hardness and wear resistance

Hardness is the basic characteristic that a toothed insert material should have.The tyre shredder toothed blade cuts the chip from the workpiece and its hardness needs to be greater than the hardness of the workpiece material.The chip edge hardness of the tire shredder toothed blade used for chip metal is generally above 60 hrc.Abrasion resistance is the ability of a material to resist wear.In general, the higher the hardness of the toothed blade material, the better its wear resistance.The harder the hardness of the hard spots in the tissue, the larger the number, the smaller the particles, and the more uniform the distribution, the better the wear resistance.

2. Sufficient strength and toughness

The tire shredder mechanical blade material must have sufficient strength and toughness to handle large pressures and work under shock and vibration conditions that often occur during cutting.

3. High heat resistance

Heat resistance is a major indicator of the cutting performance of the tooth shredder of a tire shredder.It refers to the performance of the toothed insert material to maintain a predetermined hardness, wear resistance, strength and toughness under high temperature conditions.The tire shredder toothed blade material should also have the ability to resist oxidation at high temperatures and good resistance to adhesion and diffusion.

4. Good thermal physical properties and thermal shock resistance

The better thermal conductivity of the toothed blade material of the tire shredder, the easier it is to remove the heat from the cutting zone, which helps to reduce the cutting temperature.
