The production of waste tire rubber powder requires a series of equipment and processes to be completed. There are several equipment involved in the process. The first equipment is the pretreatment equipment, which includes the Tire ring cutting machine that cuts off the inner ring of the waste tire. The Tire wire drawing machine extracts the steel wire from the tire, and the Tire shredder shreds the tire after removing the inner ring and steel wire into larger rubber blocks.
The next set of equipment involved is the Crushing equipment, which includes the Coarse crusher for preliminary crushing of the shredded rubber blocks and the Medium crusher for crushing the rubber blocks into smaller particles. After the crushing process, the Separation equipment comes into play. The Magnetic separator separates the steel wire from the rubber particles using magnetic force. The Fiber sorter separates impurities such as fibers from rubber particles, and the Airflow sorter creates air vortexes to separate rubber particles and fibers more finely.
The Grinding equipment includes the Rubber mill which grinds the crushed and separated rubber particles into rubber powder. According to different production needs, the parameters of the mill can be adjusted to produce rubber powders of different mesh sizes. The Screening equipment is used to screen the ground rubber powder to screen out the rubber powder particle size that meets the requirements. Finally, the Packaging equipment, which is the Fully automatic bagging machine quantitatively bags the rubber powder according to the set weight for easy storage, transportation and sales.
In summary, the entire waste tire rubber powder production line is composed of multiple equipment and processes that require corresponding conveying equipment such as belt conveyors to ensure smooth transmission of materials. For environmental protection and safety, the production line may also include auxiliary facilities such as dust removal equipment, atomizing spray system, water cooling system, etc.
The rubber powder produced by the waste tire rubber powder production line has various characteristics.
The rubber powder from the production line can be processed into different mesh sizes depending on specific production requirements. The particle size is usually between 30-200 meshes. Coarser rubber powder can be used in rubber products or building materials that do not require high material particle size, whereas finer rubber powder can be used in rubber products or fine chemical fields with higher requirements. Advanced production lines and processes ensure the particle size distribution is uniform, facilitating better and even dispersion of the rubber powder when mixed with other materials.
One of the benefits of using rubber powder is the reduction in weight of products. This is due to the smaller density of rubber powder. For example, the use of rubber powder in products such as automobile tires and rubber soles can lead to lighter finished products, resulting in better performance.
Rubber powder that undergoes proper processing has excellent fluidity, making it easy to transport and mix with other materials during production. Good fluidity improves production efficiency, contributing to a smooth production process.
The surface morphology of rubber powder is another physical characteristic that makes it particularly useful in composite materials. The powder surface of rubber powder often has burr-shaped structures, making it easier to bond with other colloids and materials to create better composite materials.
In addition to rubber ingredients in rubber powder, other ingredients such as additives and aging products may be present. The presence of these ingredients affects the chemical properties of rubber powder, such as vulcanization performance and aging resistance. It is necessary to test and analyze the chemical properties of rubber powder according to specific application requirements.
Rubber powder can also be modified to improve its performance. For instance, the compatibility with other materials can be improved by adding coupling agents. The dispersibility of rubber powder can be enhanced through surface treatment.
The waste tire rubber powder production line ensures the thorough separation of steel wire and fiber from waste tires, thus achieving a high level of purity. Through strict screening and separation processes, other impurities, like dust and soil, are effectively removed, resulting in rubber powder with low impurity content. High-purity rubber powder improves the performance of rubber products and reduces defects caused by the presence of impurities.
In order to process used tires, various machines are required to remove the steel wire and rubber pieces. These machines provide essential functions that are necessary to efficiently break down the tire into usable components.

The waste tire rubber powder production line's output and efficiency depend on various factors, including equipment type, scale, technical level, and production process.
Here are some common output and efficiency ranges for different production line types:
- Output: Some small waste tire rubber powder production lines, such as the 450 type unit of the tire rubber crusher, have an hourly output of about 4-6 tons. If calculated based on 300 working days per year, the annual output is about 1,500 tons.
- Efficiency: This type of small production line has a relatively low degree of automation and may require more manual operation and intervention. It is relatively weak in equipment operation stability and continuous production capacity, and the overall efficiency of the equipment is relatively low.
- Output: Usually the annual processing capacity of a medium-sized waste tire rubber powder production line is about 3,000-5,000 tons. The specific output will also be affected by factors such as equipment operation time, raw material quality and equipment maintenance.
- Efficiency: The equipment configuration of the medium-sized production line is relatively more complete, the degree of automation has been improved, the material transportation, crushing, screening and other links in the production process can be carried out more smoothly, and the production efficiency is relatively high. For example, some medium-sized production lines can achieve continuous production, with a longer effective working time every day, thus improving the overall production efficiency.
- Output: Large-scale waste tire rubber powder production lines can process up to 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 the annual output of rubber powder can reach more than 15,000 tons.
- Efficiency: Large production lines generally use advanced
technology and equipment, with a high degree of automation, and
strong collaborative working ability of various links in the
production process, which can achieve efficient and stable
production. At the same time, large production lines also have
advantages in energy utilization, equipment maintenance, etc.,
which can reduce production costs and improve production
efficiency.
