The waste tire rubber powder production line is a complex system composed of various equipment and links. It involves several stages of processing, including pretreatment, crushing, separation, grinding, screening, and packaging. Let's take a closer look at each of these stages:

Pretreatment Equipment

The pretreatment equipment includes:

• Tire ring cutting machine: This machine is used to cut off the inner ring of the waste tire for subsequent crushing. It provides convenience for subsequent processing by accurately separating the inner ring from the outer ring of the tire.
• Tire wire drawing machine: It extracts the steel wire from the tire, reducing wear on the equipment during the subsequent crushing process. It also facilitates the recycling of steel wire.
• Tire shredder: This machine shreds the tire after removing the inner ring and steel wire into larger rubber blocks. It tears the tire into relatively uniform blocks of size, preparing it for subsequent crushing and grinding.

Crushing Equipment

The crushing equipment includes:

• 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 for further crushing.
• Medium crusher: The rubber blocks processed by the coarse crusher are further crushed into smaller rubber particles, usually about 6-12 mm.

Separation Equipment

The separation equipment includes:

• Magnetic separator: This machine uses magnetic force to separate the steel wire from the rubber particles. It effectively absorbs the fine steel wires left in the rubber particles after crushing to ensure the purity of the rubber powder.
• Fiber sorter: This machine separates impurities such as fibers from rubber particles to improve the quality of the rubber powder.
• Airflow sorter: This machine creates air vortexes to separate rubber particles and fibers more finely and sort out rubber fine powder of different mesh sizes.

Grinding Equipment

The grinding equipment includes:

• Rubber mill: This machine grinds the crushed and separated rubber particles into rubber powder. The mill rotates and extrudes the rubber particles through components such as grinding discs or grinding rollers to produce rubber powders of different mesh sizes.

Screening Equipment

The screening equipment includes:

• Vibrating screen: This machine screens the ground rubber powder to filter 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.

Packaging Equipment

The packaging equipment includes:

• Fully automatic bagging machine: This machine quantitatively bags the rubber powder according to the set weight for easy storage, transportation, and sales.

In addition to the above equipment and links, the production line requires corresponding conveying equipment such as belt conveyors to ensure the smooth transmission of materials. To ensure environmental protection and safety, the production line may also be equipped with auxiliary facilities such as dust removal equipment, atomizing spray system, and water cooling system.

The waste tire rubber powder production line produces rubber powder with unique characteristics that can be useful for a variety of industrial applications. The product has the following particle size characteristics:

1. Diverse particle sizes that can be processed into rubber powder of different mesh sizes based on production requirements. The common particle size ranges between 30-200 meshes, coarser rubber powder can be used in some rubber products or building materials that do not require high particle size, while finer rubber powder can be used in rubber products or fine chemical fields.
2. Uniform particle size thanks to advanced production lines and processes. Uniform particle size makes it easier to disperse rubber powder evenly when mixed with other materials, thereby improving the quality of the final product.

The physical performance characteristics of rubber powder include:

• Small specific gravity that can reduce the weight of the product when using rubber powder to produce rubber products or other materials such as automobile tires and rubber soles.
• Good fluidity that can improve production efficiency and ensure the smooth progress of the production process.
• Special surface morphology that makes the rubber powder have stronger adhesion and bonding when used with other materials, thereby improving the performance of composite materials.

The chemical performance characteristics of rubber powder include:

• Complex ingredients that may contain additives, aging products, etc. The presence of these ingredients will affect the chemical properties of rubber powder, such as the vulcanization and aging performance. It is important to test and analyze the chemical properties of rubber powder based on specific application requirements.
• Modifiability by adding modifiers or using special treatment methods to improve its performance. For example, the compatibility of rubber powder with other materials can be improved by adding coupling agents or surface treatment can improve the dispersibility of rubber powder.

The purity characteristics of rubber powder include:

• Thorough separation of steel wire and fiber that ensures high purity of rubber powder. The high-purity rubber powder can reduce product defects caused by the presence of impurities and improve the performance of rubber products.
• Low impurity content achieved through strict screening and separation processes that remove other impurities in rubber powder, such as dust, soil, etc.
