Hardness and pressure of tire shredder blade

Blades are very important for tire recycling machines. Wear resistance, hardness, strength, heat resistance, etc., will inevitably cause higher temperatures during processing, so pay attention to them. Let's take a closer look:

Hardness is a fundamental characteristic of shredder blades. The hardness of the tire recycling machine blade must be greater than the hardness of the workpiece data. The cutting edge hardness of shredder blades for chip metal is generally above 60hrc. Abrasion resistance is the ability of materials to resist abrasion. Generally, the harder the blade material of the tire recycling machine is. The better the abrasion resistance.

The higher the hardness of the hard spots in the arrangement, the larger the number, the smaller the particles, and the more uniform the distribution, the better the wear resistance. Abrasion resistance is also related to the chemical composition, strength, microscopic arrangement of the data and the temperature of the conflict zone. The formula can indicate the abrasion resistance of the data wr; we = kico. 5e-0. In 8h1. 43 formula, the higher the hardness, the better the abrasion resistance.

Strength and resistance

In order to make the shredder blades receive a lot of pressure and operate under the impact and sensation conditions that often occur in the shredding process, without chipping and breaking, it is necessary for the mechanical blade data to have sufficient strength and resistance.

Heat resistance

Heat resistance is the primary indicator of the shredder function of shredder blade data. It refers to the function that the shredder blade data adheres to a sufficiently good hardness, abrasion resistance, strength and resistance under high temperature conditions. Shredder blade information should also have the ability to resist oxidation at high temperatures and outstanding anti-adhesion and anti-dispersion ability, that is, shredder blades should have outstanding chemical stability.

Thermophysical and thermal shock resistance

The better the thermal conductivity of the tire recycling machine blade material, the easier the shredding heat is to dissipate from the shredding area, which is helpful to reduce the shredding temperature.
