What are the working processes of the tire recycling line ?
1. Feeding and pretreatment :
Collection and transportation: Collect waste tires from various recycling points and transport them to recycling plants by vehicles and other means of transportation. During transportation, the tires need to be properly fixed and protected to prevent them from rolling or being damaged.
Preliminary inspection and classification: Conduct preliminary inspection on the recycled tires and pick out tires that do not meet the recycling requirements, such as tires that are severely damaged, overly aged, and cannot be effectively recycled. At the same time, classify the tires according to their size, type, etc., so that they can be processed in a targeted manner later.
Remove impurities: Clean dirt, dust, stones and other impurities on the tire surface to prevent these impurities from causing wear and tear on subsequent processing equipment or affecting product quality. Some tire recycling lines are also equipped with special cleaning equipment to clean tires.
Wire drawing or bead cutting: For tires with wire bead, you need to use a wire drawing machine to draw out the wire bead on both sides of the tire, or use a bead cutting machine to separate the wire bead from the tire carcass. This will facilitate the subsequent crushing of the tire and is also conducive to the recycling of the wire.
2. Crushing process:
Primary crushing: Put the pre-treated tires into the tire crusher for crushing. The tire crusher usually uses shearing, tearing and other methods to crush the tires into larger rubber blocks, generally about 5-10 cm in size.
Screening and recycling: The crushed rubber blocks are screened by screening equipment. Rubber blocks that meet the size requirements enter the next step of processing, and rubber blocks that are too large are returned to the crusher for re-crushing until they reach the required size.
3. Wire separation:
Magnetic separation: The rubber blocks that have been crushed once are transported to the magnetic separator, which uses magnetic force to separate the steel wire from the rubber. The magnetic separator can effectively absorb the steel wire and separate it from the rubber. The separated steel wire can be recycled and reused.
Fine separation: For some recycling lines that have higher requirements for steel wire separation, they will also be equipped with equipment such as steel wire separators to further separate and remove the steel wires in the rubber blocks to improve the purity of the rubber.
4. Rubber Crushing:
Medium crushing: The rubber blocks after wire separation enter the rubber medium crusher, which crushes them into smaller rubber particles, generally around 1-6 mm in size.
Fine crushing or grinding: According to the product requirements, if rubber powder needs to be produced, the medium-crushed rubber particles are sent to a rubber fine crusher or grinder for further crushing and grinding to make it into fine rubber powder. Usually the particle size of the rubber powder can reach 40-100 mesh or even finer.
5. Fiber separation: Use a fiber separator to separate the fiber material in the rubber particles from the rubber. Fiber separation equipment usually uses screening, air separation and other methods to separate the fiber from the rubber particles by taking advantage of the difference in physical properties between the fiber and rubber. The separated fibers can be recycled separately.
6. Screening and grading:
Screening: The crushed rubber particles or rubber powder are screened through screening equipment to remove impurities and particles that do not meet size requirements to ensure product quality and particle size uniformity.
Classification: According to different application requirements, the sieved rubber particles or rubber powder are classified into different particle size grades to meet the needs of different customers.
7. Packaging and storage:
Packaging: The screened and graded rubber particles or rubber powder can be packaged in woven bags, ton bags and other packaging materials, and quantitative packaging can be carried out according to customer requirements.
Storage: Store the packaged rubber products in a dry, ventilated, cool warehouse, away from direct sunlight and rain to ensure the quality and performance of the products .
