Rubber Tire Granulation Processing

Updated: 2026-07-18

Overview

Rubber tire granules processing is a critical step in the recycling of used tires, transforming them into reusable rubber granules. This process not only addresses the environmental issue of tire disposal but also provides a sustainable material for various industries. The granules are produced by shredding and grinding used tires, followed by cleaning and sorting to remove metal and fiber contaminants. The processed rubber granules are valued for their durability, elasticity, and cost-effectiveness. They serve as a key raw material in industries such as construction, sports, and landscaping, offering an eco-friendly alternative to virgin rubber.

Structure and Working Principle

The processing of rubber tire granules involves several stages, starting with the collection and transportation of used tires to processing facilities. The tires are then shredded into smaller pieces using industrial shredders. These pieces undergo further grinding to produce granules of varying sizes, typically ranging from 1mm to 10mm. The granules are then cleaned to remove steel wires, fibers, and other impurities. Advanced magnetic separators and air classifiers are used to ensure high purity. The final product is sorted by size and packaged for distribution. The entire process is designed to maximize resource recovery while minimizing environmental impact.

Key Features

Rubber tire granules are known for their excellent shock absorption, making them ideal for sports surfaces and playgrounds. They are also highly durable and resistant to weathering, which extends their lifespan in outdoor applications. Additionally, the granules provide excellent traction and noise reduction, making them suitable for road construction. Another notable feature is their eco-friendliness. By recycling used tires, the granules help reduce landfill waste and the carbon footprint associated with rubber production. Their cost-effectiveness compared to virgin rubber further enhances their appeal in various industries.

Application Areas

Rubber tire granules are widely used in the construction of sports fields, including running tracks and artificial turf. Their shock-absorbing properties make them safe for playgrounds and recreational areas. In road construction, they are mixed with asphalt to improve durability and reduce noise pollution. Other applications include flooring for gyms and industrial facilities, where their slip-resistant and cushioned properties are beneficial. The granules are also used in landscaping as mulch or ground cover, providing a sustainable alternative to traditional materials.

Maintenance and Precautions

Proper maintenance of rubber tire granules involves regular cleaning to remove debris and contaminants. For sports surfaces, periodic leveling and top-up may be required to maintain performance and safety. In road construction, the granules should be mixed correctly with asphalt to ensure optimal bonding and longevity. Precautions include ensuring that the granules are free from sharp objects or metal remnants, which could pose safety hazards. It is also important to source granules from reputable suppliers who adhere to environmental and quality standards.

B2B Procurement Guide

When procuring rubber tire granules, businesses should consider factors such as granule size, purity, and intended application. Uniform granule size ensures consistency in performance, especially for sports surfaces and playgrounds. Purity is critical to avoid contaminants that could affect the product's quality and safety. Certifications such as ISO 14001 for environmental management and ASTM standards for rubber granules can serve as indicators of quality. Price negotiations should take into account volume discounts and long-term supply agreements. It is also advisable to request samples and conduct tests before large-scale procurement.
