Rubber granules are recycled granular materials produced from waste tires and rubber products through processes such as crushing, cutting, and cryogenic grinding. They are characterized by good elasticity, wear resistance, and wide applicability, and are commonly used in industries such as sports tracks, artificial turf infill, flooring materials, shock-absorbing pads, and molded rubber products.
Due to the diverse particle sizes and irregular shapes, the screening process places higher demands on the structural design and efficiency of the equipment. Sanyuantang Machinery provides efficient and durable professional screening solutions for rubber granules.
1. Irregular Particle Shape
Rubber granules are typically irregular in shape, exhibiting significant variations. This places high demands on the screen's throughput and cleaning capabilities.
2. High Elasticity and Prone to Jumping
The granules are highly elastic and tend to jump easily on the screen surface, requiring appropriate vibration methods to improve screening efficiency.
3. Prone to Dust Generation
The crushing process often generates fine powder, necessitating screening equipment with excellent sealing and dust removal capabilities.
4. Wide Particle Size Range
Requirements exist for particles ranging from 0.5mm to over 5mm, necessitating precise grading through multiple layers of screens.
Sports Field Running Track Materials (EPDM/SBR Granules)
Artificial Turf Infill Granules
Anti-Slip Ground Mat Materials
Reprocessing of Rubber Products (Shoe Soles, Seals, etc.)
Sound Insulation, Shock Absorption, and Cushioning Materials
Different applications have strict requirements for particle size and uniformity; therefore, screening and grading are essential processes.
Challenges in Screening and Grading Rubber Granules
In the rubber granule industry, common screening challenges include:
Irregular particle shapes leading to low screening efficiency
High elasticity causes material jumping
High dust levels are impacting the environment
Large-scale production demands high stability from screening machines
Sanyuantang Machinery, considering material characteristics, effectively solves these problems through combinations of different equipment.
1. Linear Vibrating Screen
Suitable for high-volume rubber granule screening. Features:
Multi-layer screens allow for 2-5 grade classification
Large screening area, high throughput
Supports a fully enclosed structure to reduce dust spillage
Stable operation, low maintenance cost
2. Tumbler Screen
Designed for irregular, lightweight granules:
Simulates manual screening action for more accurate grading
Minor particle vibration, higher screening efficiency
Suitable for high-precision screening processes
3. Rotary Vibrating Screen
Suitable for smaller production volumes or fine grading:
Small footprint, easy screen replacement
Can be used to separate fine rubber powder from granules
