Product Description:

The waste tire rubber powder production line consists of various equipment and links that work together to produce high-quality rubber powder. The equipment and processes involved are detailed below:

The pretreatment equipment is responsible for preparing the waste tire for subsequent processing:

• Tire ring cutting machine: This machine cuts off the inner ring of the waste tire for further processing. The equipment quickly and accurately separates the inner ring from the outer ring of the tire, providing convenience for subsequent processing.
• Tire wire drawing machine: This machine extracts the steel wire from the tire. The steel wire is extracted to reduce wear on the equipment during subsequent crushing processes and is also convenient for the steel wire to be recycled separately.
• Tire shredder: This machine shreds the tire, after removing the inner ring and steel wire, into larger rubber blocks. The shredder's knives are strong and sharp, and can cope with the high-strength rubber material of the tire, tearing the tire into relatively uniform blocks of size, preparing for subsequent crushing and grinding.

The crushing equipment is responsible for crushing the shredded rubber blocks into smaller rubber particles:

• Coarse crusher: This machine preliminarily crushes the shredded rubber blocks, breaking them into rubber blocks of about tens of millimeters in size. The coarsely crushed rubber blocks will pass through the screening system. If they do not meet the requirements, they will be sent back to the crushing chamber by the round mesh screen for further crushing until they meet the requirements.
• Medium crusher: This machine further crushes the rubber blocks processed by the coarse crusher into smaller rubber particles, usually about 6-12 mm.

The separation equipment is responsible for separating impurities from the rubber particles:

• Magnetic separator: This equipment uses magnetic force to separate the steel wire from the rubber particles. The magnetic separator can effectively absorb any leftover fine steel wires, ensuring the purity of the rubber powder.
• Fiber sorter: This machine separates impurities such as fibers from rubber particles through a specific sorting principle to improve the quality of rubber powder.
• Airflow sorter: This machine creates air vortexes to finely separate rubber particles and fibers, recycle rubber powder in different grades, and sort out rubber fine powder of different mesh sizes.

The grinding equipment is responsible for grinding the separated rubber particles into rubber powder:

• Rubber mill: This machine grinds the crushed and separated rubber particles into rubber powder through the rotation and extrusion of components such as grinding discs or grinding rollers. The mill's parameters can be adjusted to produce rubber powders of different mesh sizes, such as 40 mesh-200 mesh rubber powder.

The screening equipment is responsible for screening the ground rubber powder to remove any particles that do not meet the requirements:

• Vibrating screen: This equipment screens the ground rubber powder to screen out the rubber powder particle size that meets the requirements. Rubber powder that does not meet the particle size requirements will be returned to the grinder for re-grinding until it reaches the specified particle size standard.

The packaging equipment is responsible for packaging the rubber powder for easy storage, transportation, and sales:

• Fully automatic bagging machine: When the rubber powder meets the requirements after screening, this machine quantitatively bags the rubber powder according to the set weight.

To ensure smooth transmission of materials, corresponding conveying equipment such as belt conveyors are needed. Additionally, for environmental protection and safety, auxiliary facilities such as dust removal equipment, atomizing spray system, water cooling system, etc. may also be equipped with the production line.

Features:

The rubber powder produced by the waste tire rubber powder production line has the following characteristics:

• Diverse Particle Sizes: Rubber powder can be processed into different meshes according to production requirements. The common particle size range is between 30-200 meshes. Finer powder can be used in rubber products or fine chemical fields with higher requirements.
• Uniform Particle Size: Advanced production lines ensure that the rubber powder's particle size distribution is uniform, which is important for the powder's performance stability in various applications.

• Small Specific Gravity: Rubber powder's density is small, reducing the weight of products when used to produce rubber products or other materials.
• Good Fluidity: The proper processing of rubber powder gives it good fluidity, which can improve production efficiency and ensure the smooth progress of the production process.
• Special Surface Morphology: Rubber powder's surface usually has burr-shaped structures, making the powder have stronger adhesion when combined with other materials.

• Complex Ingredients: Rubber powder may contain additives that affect its chemical properties. Specific testing and analysis are required for users' specific application requirements.
• Modifiable: Rubber powder can be modified to improve its performance, such as improving its compatibility with other materials or its dispersibility.

• Thorough Separation of Steel Wire and Fiber: The waste tire rubber powder production line can almost completely separate steel wire and fiber, ensuring the purity of rubber powder.
• Low Impurity Content: Rubber powder is subject to strict screening and separation processes to remove impurities like dust and soil.

Technical Parameters:

Equipment Details 1. Tire Steel Wire Drawing Machine:
The Tire Steel Wire Drawing Machine is used to remove the tire bead wire. This wire is present inside the tire and must be removed before the tire can be shredded. 2. Shredder with Rolling Screen:
The Shredder with Rolling Screen is used to shred the tire into ≤50mm rubber pieces. These smaller rubber pieces are easier to process and use in new products. 3. Rubber Grinder:
The Rubber Grinder is used to peel the capillary wire in the tire and obtain 1-5mm rubber particles. This process involves separating the rubber from the steel wire in the tire. 4. Rubber Milling Machine:
The Rubber Milling Machine is used to grind the rubber to 15-200 mesh as required. This is to ensure that the rubber particles are of uniform size and can be used efficiently in the manufacturing process. 5. Magnetic Separator:
The Magnetic Separator is used to remove wire from rubber particles. This ensures that the final product is purely rubber and does not have any steel wire or other contaminants. 6. Fiber Separator:
The Fiber Separator is used to separate fibers from tire particles. This ensures that the rubber particles are of high quality and do not have any impurities. 7. Dust Removal Equipment:
The Dust Removal Equipment is used to remove dust generated during the recycling process. This ensures that the work environment remains clean and safe for workers.

Applications:

The output and efficiency of the waste tire rubber powder production line depend on various factors, including equipment type, scale, technical level, and production process. Below are the output and efficiency ranges for different production line sizes:

• Output: Some small waste tire rubber powder production lines have an hourly output of about 4-6 tons, with an annual output of about 1,500 tons.
• Efficiency: This type of production line has a low degree of automation and requires more manual operation and intervention. It has lower equipment operation stability and continuous production capacity, resulting in overall lower efficiency.

• Output: A medium-sized waste tire rubber powder production line typically processes 3,000-5,000 tons annually; output may vary based on equipment operation time, raw material quality, and equipment maintenance.
• Efficiency: The medium-sized production line has improved equipment configuration and automation, making material transportation, crushing, screening, and other processes smoother. Continuous production is possible, leading to longer effective working time and higher production efficiency.

• Output: A large-scale waste tire rubber powder production line can process tens of thousands of tons or even more annually. For example, some large production lines can process up to 20,000 tons per year and produce more than 15,000 tons of rubber powder annually.
• Efficiency: A large production line typically uses advanced technology and equipment, with a high degree of automation and a strong collaborative working ability. This leads to efficient and stable production, as well as advantages in energy utilization and equipment maintenance, ultimately reducing production costs and improving efficiency.
