The production line for producing waste tire rubber powder consists of multiple pieces of equipment and links that must operate together effectively to produce high-quality rubber powder. The production process involves several stages, which are crucial to the production quality. The complete production line is described in detail below:

• Tire ring cutting machine: This machine is used to cut off the inner ring of the waste tire for subsequent crushing.
• Tire wire drawing machine: This machine is used to extract the steel wire from the tire for subsequent recycling.
• Tire shredder: This machine shreds the tire after removing the inner ring and steel wire into larger rubber blocks.

These machines are crucial for preparing the tires for the next stage of production and ensuring the uniformity of the rubber blocks.

• Coarse crusher: This machine provides preliminary crushing of the shredded rubber blocks, breaking them into rubber blocks of about tens of millimeters in size.
• Medium crusher: This machine further crushes the rubber blocks into smaller rubber particles.

These machines are critical for breaking the rubber blocks into smaller and uniform sizes.

• Magnetic separator: This machine effectively separates the steel wire from the rubber particles to ensure purity.
• Fiber sorter: This machine separates impurities such as fibers from rubber particles to improve the quality of rubber powder.
• Airflow sorter: This machine separates the rubber particles and fibers more finely and can sort out rubber fine powder of different mesh sizes.

These machines are necessary for removing impurities and ensuring the purity and uniformity of the rubber powder.

• Rubber mill: This machine grinds the crushed and separated rubber particles into rubber powder of different mesh sizes.

This machine is critical for producing the desired mesh size of rubber powder.

• Vibrating screen: This machine screens out the rubber powder particle size that meets the requirements.

This machine is necessary for ensuring the desired particle size of the rubber powder.

• Fully automatic bagging machine: This machine is used for quantitative packaging of rubber powder according to the set weight for easy storage, transportation and sales.

This machine is necessary for efficient and effective packaging of the rubber powder.

In addition to the mentioned equipment, the production line requires other auxiliary facilities such as conveying equipment, dust removal equipment, atomizing spray system, water cooling system, etc., for environmental protection and safety of the production process.

The waste tire rubber powder production line produces rubber powder with the following characteristics:

• Diverse particle sizes: It can be processed into rubber powder of different meshes according to different production requirements, and the common particle size range is between 30-200 meshes.
• Uniform particle size: Advanced production lines and production processes can ensure that the particle size distribution of rubber powder is relatively uniform.

Uniform particle size can make it easier to disperse rubber powder evenly when mixed with other materials, thereby improving the quality of the product.

• Small specific gravity: The density of rubber powder is relatively small, which makes it possible to reduce the weight of the product when using rubber powder to produce rubber products or other materials.
• Good fluidity: The rubber powder that has been properly processed has good fluidity and can be smoothly transported, mixed, and other operations during the production process.
• Special surface morphology: The powder surface of rubber powder usually has many burr-shaped structures, which make it have stronger adhesion and bonding when combined with other colloids.

• Complex ingredients: In addition to rubber ingredients, rubber powder may also contain some additives, aging products, etc.
• Modifiable: Rubber powder can be modified by adding some modifiers or using special treatment methods to improve its performance.

• Thorough separation of steel wire and fiber: High-quality waste tire rubber powder production line can almost completely separate the steel wire and fiber in waste tires, thereby ensuring the high purity of rubber powder.
• Low impurity content: During the production process, other impurities in rubber powder, such as dust, soil, etc., can be effectively removed.

The efficiency and output of a waste tire rubber powder production line are determined by various factors like equipment, technical level, production process, and scale. Listed below are the different ranges of efficiency and output:

1. Small Production Line:

   • Output: Certain small production lines like the 450 type unit of the tire rubber crusher have an hourly output of around 4-6 tons. The annual output is approximately 1,500 tons when calculated based on 300 working days per year.
   • Efficiency: Small production lines like this rely more on manual operation and have less automation. These production lines have equipment stability and low continuous production capacity, which limits their overall efficiency.

2. Medium-sized Production Line:

   • Output: The annual processing capacity of most medium-sized waste tire rubber powder production lines is around 3,000-5,000 tons. The processing capacity is dependent on factors like raw materials, equipment maintenance, and operation time.
   • Efficiency: Medium-sized production line equipment are configured with more advanced automation levels that allow for smoother operation during transportation and production processes. Some medium-sized lines have longer effective working times conducted through continuous production, which increases their overall production efficiency.

3. Large Production Line:

   • Output: Large-scale waste tire rubber powder production lines can process tens of thousands of tons annually. A good example is a large production line that can process up to 20,000 tons annually with an output of more than 15,000 tons of rubber powder.
   • Efficiency: These production lines employ advanced technology and equipment, with high automation levels and strong collaborative working abilities among various production processes. The advantages of using large production lines such as energy utilization and equipment maintenance cuts down on production costs and improves production efficiency.
