Our rubber cracker mill is the core machine responsible for transforming coarse rubber chips from a tire shredder into high-value, fine rubber powder or granules. It plays an indispensable role in any modern scrap tire recycling line, utilizing a powerful combination of grinding, screening, and magnetic separation to produce commercial-grade rubber powder with over 99% purity and a controllable output size (5-40 mesh). If you are seeking a reliable solution to convert waste tires into a profitable recycled material, our rubber crusher is the essential next step in achieving your goal.

Raw Material & Finished Product
- Input Material: 50-150mm tire chips or rubber blocks, typically produced by a primary tire shredder.
- Finished Product: 5-40 mesh, high-purity, steel-free rubber powder or granules. This final product is an ideal raw material for manufacturing reclaimed rubber sheets, modified asphalt, waterproof membranes, rubber tiles, and athletic running tracks.


Key Features of Our Rubber Cracker Mill
- Adjustable Powder Size: By adjusting the gap between the rollers and changing the screen mesh, you can easily produce various specifications of rubber powder, from 5 to 40 mesh, to meet diverse market demands.
- Coarser Powder, Higher Output: The machine’s design follows a core principle: the coarser the final powder, the higher the hourly output. We can recommend the most efficient configuration based on your capacity targets and product requirements.
- Dual Magnetic Separation for >99% Purity: The system integrates two stages of powerful magnetic separation. The first stage performs a preliminary separation after grinding, while the second stage conducts a final cleaning before discharge, effectively removing fine steel wire and ensuring a rubber purity of over 99%.
- Durable Grinding System: The core components—the grinding rollers—are centrifugally cast from a high-hardness, wear-resistant alloy. The surface is exceptionally durable and built for a long service life, significantly reducing maintenance costs.
- Scalable Capacity Options: We offer a range of models with capacities from 80 kg/h to 2300 kg/h. Whether you are a small start-up or a large-scale recycling plant, we have a solution that fits your business needs.



Working Principle of Rubber Crusher
The workflow of the rubber cracker mill is precise and highly efficient:
- Feeding & Grinding: Rubber chips are fed between two alloy rollers that rotate towards each other at different speeds. The speed differential creates a powerful shearing and frictional force that rapidly grinds the rubber into smaller particles.
- Screening & Recirculation: The ground material is sent to a vibrating screening system. Fine powder that meets the size specification passes through the screen to the next stage. Oversized granules are automatically returned to the infeed hopper for re-grinding, creating an efficient closed-loop system.
- Magnetic Separation: As the material is conveyed, it passes through powerful magnetic separators that attract and remove the fine steel wire liberated during the grinding process.
- Final Product Collection: The screened and purified rubber powder is transported to a collection silo, ready for bagging and shipping.
