The double-shaft waste tire shredder is a key equipment in the field of waste tire recycling and treatment, and is of great significance to promoting resource recycling and environmental protection.

From the working principle, it relies on two synchronous counter-rotating knife shafts to carry out operations. The knife shaft is equipped with a special blade. When the waste tire enters the shredding chamber, the blade will gradually break the tire into uniform small pieces with strong shear force, tearing force and extrusion force. This crushing method is efficient and stable, and can cope with waste tires of different sizes and thicknesses.

In terms of equipment structure, the double-shaft waste tire shredder is scientifically and reasonably designed. The sturdy and durable frame provides stable support for the entire equipment, ensuring that there will be no shaking or deformation under high-intensity operation. The two knife shafts are connected by a precise transmission system to ensure synchronous speed and smooth operation. The blade is made of high-strength and high-wear-resistant alloy steel. After a special heat treatment process, it has excellent hardness and toughness, can remain sharp for a long time, reduce replacement frequency, and reduce use costs.

The equipment has significant advantages. The crushing efficiency is extremely high, and a large number of waste tires can be processed in a short time, effectively improving production efficiency. The material after crushing has uniform particle size, and the blade spacing can be adjusted according to actual needs to produce rubber fragments of different specifications to meet the diverse subsequent processing requirements. At the same time, the double-axis waste tire shredder has stable and reliable operation, low failure rate, and simple maintenance, which greatly reduces downtime and repair costs.

In terms of application scenarios, it is widely used in tire recycling plants, rubber product companies, and resource recycling bases. Waste tires processed by the shredder can be used as raw materials to produce rubber particles, recycled rubber, waterproof materials, etc., to realize the resource utilization of waste tires, which not only alleviates the environmental pressure caused by the accumulation of waste tires, but also creates considerable economic benefits.

The double-axis waste tire shredder has become an indispensable and important equipment in the waste tire recycling industry with its excellent performance and wide application prospects.

The double-shaft waste tire shredder is a key equipment in the field of waste tire treatment. Its working principle is based on the principle of mechanical mechanics. Through the synergistic effect of two rotating cutter shafts, the waste tires can be efficiently crushed. The following is an analysis from the core structure and operation logic.

Core structure composition

The double-shaft waste tire shredder is mainly composed of two parallel and synchronously counter-rotating cutter shafts, on which many special blades are installed. These blades are arranged according to a certain pattern and spacing to form a strong shearing and tearing action surface. In addition, the equipment is also equipped with a drive system to provide power for the rotation of the cutter shaft; the feed port is used to feed the waste tires into the shredding chamber; and the discharge port is responsible for discharging the crushed materials.

Detailed explanation of operation logic

1.Material entry and initial bite

When the waste tire enters the shredding chamber through the feed port, it will first contact the blades on the two rotating cutter shafts. Since the cutter shafts rotate in the opposite direction, the blades will clamp the tire like a pliers, generating a strong bite force to initially fix the tire in the shredding area.

2.Shearing and tearing action

As the cutter shaft continues to rotate, relative motion will be formed between the blades. This relative movement generates a strong shear force, which cuts the tire like a pair of scissors cutting paper. At the same time, the sharp edge and special shape of the blade will exert a tearing force on the tire, further destroying the structure of the tire. Under the combined effect of shearing and tearing, the tire begins to be gradually broken.

3.Extrusion and crushing completed

During the shearing and tearing process, the knife shaft will also exert an extrusion effect on the tire. After the tire is squeezed, the internal fiber and rubber structure will be further destroyed and become looser. As the knife shaft continues to rotate, the tire is gradually broken into small pieces and finally discharged from the discharge port.

4.Crushing effect guarantee

In order to ensure the crushing effect, the blade material of the double-shaft waste tire shredder is usually made of high-strength and high-wear-resistant alloy steel to ensure that the blade remains sharp during long-term operation. In addition, the equipment is also equipped with an intelligent control system, which can automatically adjust the rotation speed of the knife shaft and the spacing between the blades according to the material, thickness and crushing requirements of the tire to achieve the best crushing effect.
