Automated Scrap Tire Crushing Plant with PLC Control and DC53 type crushing knife

Product Description:

The production line for waste tire rubber powder is made up of several pieces of equipment. These different machines work together to create high-quality rubber powder while also removing impurities and ensuring environmental safety. The following is a detailed description of the various equipment used.

• Tire Ring Cutting Machine: The tire ring cutting machine is used to cut off the inner ring of the waste tire before crushing. This machine quickly and accurately separates the inner ring from the outer ring of the tire, providing convenience for subsequent processing.
• Tire Wire Drawing Machine: The tire wire drawing machine extracts the steel wire from the tire. Since the tire contains a steel wire structure, the steel wire is extracted by the wire drawing machine. It helps in reducing the wear on the equipment during the subsequent crushing process and also makes it convenient for the steel wire to be recycled separately.
• Tire Shredder: The tire shredder shreds the tire into larger rubber blocks after removing the inner ring and steel wire. 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.

• Coarse Crusher: The coarse crusher performs initial crushing of the shredded rubber blocks, breaking them into rubber blocks of about tens of millimeters in size. The coarsely crushed rubber blocks 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: The rubber blocks processed by the coarse crusher are further crushed into smaller rubber particles, usually about 6-12 mm.

• Magnetic Separator: The magnetic separator separates the steel wire from the rubber particles using magnetic force. As there may still be some fine steel wires left in the rubber particles after crushing, the magnetic separator can effectively absorb these steel wires, helping to ensure the purity of the rubber powder.
• Fiber Sorter: The fiber sorter separates impurities such as fibers from the rubber particles. In addition to steel wires, tires also contain some fiber materials. The fiber sorter separates these fibers from rubber particles through a specific sorting principle to improve the quality of rubber powder.
• Airflow Sorter: The airflow sorter creates air vortexes to separate rubber particles and fibers more finely and recycles rubber powder in grades as needed, sorting out rubber fine powder of different mesh sizes.

• Rubber Mill: The rubber mill grinds the crushed and separated rubber particles into rubber powder. The working principle of the mill is to grind the rubber particles into powder through the rotation and extrusion of components such as grinding discs or grinding rollers. According to different production needs, the parameters of the mill can be adjusted to produce rubber powders of various mesh sizes, such as 40 mesh-200 mesh rubber powder.

• Vibrating Screen: The vibrating screen 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 is returned to the grinder for re-grinding until it reaches the specified particle size standard.

• Fully Automatic Bagging Machine: When the rubber powder meets the screening requirements, the fully automatic bagging machine quantitatively bags the rubber powder according to the set weight for easy storage, transportation, and sales.

During the operation of the entire waste tire rubber powder production line, corresponding conveying equipment, such as belt conveyors, etc., are also required to connect various equipment to ensure the smooth transmission of materials. At the same time, in order to ensure the environmental protection and safety of the production process, the production line may also be equipped with auxiliary facilities such as dust removal equipment, atomizing spray system, water cooling system, etc.

Applications:

The output and efficiency of a waste tire rubber powder production line can vary based on several factors such as equipment type, scale, technical level, and production process. The following are some common output and efficiency ranges:

Small waste tire rubber powder production lines have limited hourly and annual output. For instance, the 450 type unit of the tire rubber crusher has an output of approximately 4-6 tons an hour, equating to 1,500 tons annually based on a 300 day working year. This production line has a relatively low degree of automation that requires more manual operation and intervention. It also has weak equipment operation stability and continuous production capacity, thus reducing the overall efficiency of the equipment.

A medium-sized waste tire rubber powder production line has an annual processing capacity of about 3,000-5,000 tons. The specific output is determined by the equipment operation time, raw material quality, and equipment maintenance. Medium-sized production lines have a relatively complete equipment configuration and improved automaton degree, resulting in smooth material transportation, crushing, screening, and other production process links. This leads to a high production efficiency, enabling continuous production and more extended effective working time every day.

Large-scale waste tire rubber powder production lines have an annual processing capacity of up to tens of thousands of tons or more. Some of these lines can process up to 20,000 tons per year, which translates to an annual rubber powder output of more than 15,000 tons. They use advanced equipment and technology, resulting in a high degree of automation and efficient and stable production. Large production lines also benefit from energy utilization and equipment maintenance advantages that reduce production costs and enhance efficiency.
