The rubber powder crusher machine can efficiently convert waste tire rubber blocks (30-100mm) into 5-40 mesh fine rubber powder, and simultaneously sort steel wire and nylon fiber. Through multi-stage crushing and accurate screening, the equipment can customize the output of rubber powder with different particle sizes (suitable for mats, highways, recycled rubber, rubber runway, and other scenarios), so that every gram of waste tire rubber becomes a high-value-added raw material.
Rubber powder crusher machine core features
- Adopting a low-power motor and optimized transmission system, considering high capacity and energy saving, reduces operating costs.
- Crushing, screening, and sorting are completed simultaneously, accurately separating steel wire (recycling steelmaking) and nylon fiber (secondary processing).
- The crushing blades and screens are made of tungsten carbide/high manganese steel, which is impact and wear resistant. This prolongs the rubber powder crusher machine’s service life and reduces the frequency of maintenance.
- Configuration of multi-stage vibration screening module, supports 5-40 mesh rubber powder grading output (adjustable), to meet the needs of different scenarios (mats, asphalt, recycled rubber, etc.).
- Built-in circulating water-cooling and air-cooling technology prevents the rubber from sticking or degrading due to high crushing temperature, and guarantees the quality and production efficiency of rubber powder.
- Frequency conversion drive technology realizes stepless adjustment of rotational speed and crushing gap, adapting to the processing of rubber blocks of different hardness, with strong compatibility.
- Horizontal integrated design to reduce the footprint, with a noise-reducing shell and shock-absorbing base, suitable for factories and environmental parks intensive layout.
- Quick-disassembly structure of key parts supports quick cleaning or replacement, reduces downtime, and improves comprehensive utilization rate.
Rubber powder line application scope and scene
- Construction of sports facilities: produce 5-40 mesh fine rubber powder, used for plastic running track, sports ground mats, children’s playground buffer layer, to enhance the elasticity and safety.
- Construction building materials: processing rubber floor tiles, sound insulation boards and other products, suitable for 10-20 mesh medium-grain rubber powder, both wear-resistant and environmentally friendly.
- Waterproof material manufacturing: provide 20-40 mesh ultra-fine rubber powder as the core additive for waterproof membrane and coating to enhance the ductility and anti-aging properties of the material.
- Transportation infrastructure applications: produce modified asphalt special rubber powder (5-10 mesh coarse particles), used in highways, airport runway pavement, reduce noise and extend the service life.
- Recycling of rubber products: providing customized particle size rubber powder raw materials for tire retreading, seals, industrial rubber sheets, etc., reducing the cost of new materials.
- Circular economy scenario: synchronous sorting of steel wires (steel refining) and nylon fibers (textile auxiliary materials), realizing “full-component resourcing” of waste tires.
Structural Composition of Rubber Grinding and Screening Unit
Core Components
The rubber powder crusher machine adopts integrated linkage design, the core consists of main feeder (uniformly conveying rubber blocks), rubber crusher (high-speed hammer impact crushing), main/secondary vibrating screen and coarse/fine magnetic separator (two-stage magnetic separation to remove impurities of steel wire), supplemented by the discharge port diversion device to realize the accurate sorting of rubber powder, steel wire and nylon fiber.
Working Principle Flow
- Raw material crushing: the rubber block enters the rubber crusher through the inlet, and is crushed into ≤20mm particles by the impact of high-speed hammers.
- Main vibrating screen: screen the rubber particles, 5-40 mesh fine powder directly output, coarse particles (>40 mesh) into the secondary secondary vibrating screen crushing.
- Deputy vibrating screen: the residual coarse material after secondary screening returns to the crusher for recycling, ensuring the full amount of fine conversion.
- Coarse magnetic separator: preliminary adsorption of large particles of steel wire (such as tire bead residual steel wire).
- Fine magnetic separator: removes metal impurities at crumb level in depth to ensure the purity of rubber powder (impurity rate <0.5%).
- Finished product output: clean rubber powder is discharged from the discharge port, and steel wire and nylon fiber are sorted and recycled simultaneously.
