Why Screening and Magnetic Separation Matter in Rubber Granules Machine

In any tire recycling plant, producing clean, uniform, and high-purity rubber powder is the ultimate goal. While the rubber granules machine or tire granulator gets most of the attention, it’s the screening system and magnetic separator that truly determine the final product quality. Screening and magnetic separation are the esssential components for clean, high-value output.

If you’re running or planning a rubber granules machine line, here’s why you shouldn’t overlook these two vital components—and how they can improve the performance, stability, and output of your tire granules making machine, helping the entire production process run far more efficiently.

The Role of Screening in Rubber Granules Machine

After the initial grinding process by the rubber granules machine, the output granules are not always completely consistent in size and may contain particles of different specifications. To obtain more uniform rubber granules and improve the quality of the final product, an efficient separation step is needed. That’s where the vibrating screening system comes in. It helps classify the ground rubber particles according to size, removes oversized materials for further processing, and ensures smoother operation in the production line. Shuliy group will introduce its main features to you:

After using screening machine you will get:

Without proper screening, your tire granules making machine line could end up producing uneven, low-value material.

Magnetic Separator: Ensuring Clean, Steel-Free Rubber

During tire grinding, tiny steel wires from the tire bead or belts can remain mixed in with the rubber powder. A dedicated magnetic separation system removes these metal contaminants efficiently, helping ensure your granules are safe, clean, and suitable for further processing, storage, or use in high-quality end products.

Features of Our Magnetic Separation Unit:

• Double-stage design: rough + fine separation
• Uses high-power rare-earth magnets
• Works continuously in-line with the tire granulator
• Requires minimal maintenance and no consumables

Why do your rubber powder production line need magnetic separators?

• Prevents steel contamination in final products
• Extends the service life of tile molds or rubber processing machines
• Enhances safety and quality control, especially for export-grade rubber powder

Even the best rubber granulator can’t ensure product purity without magnetic cleanup.

Integration with Rubber Grinding Machine Systems

Both the screening and magnetic separator units are designed to work seamlessly with your rubber granules machine (rubber grinding machine), helping to improve efficiency, consistency, and product quality. We provide complete layouts that include the whole working process, from material feeding and grinding to screening, metal removal, and final granule collection:

First, the rubber powder flows from the tire granulator into a screening machine, where it begins the initial separation process for more consistent particle sizing.

Secondly, Oversize particles are automatically returned for further processing.

Then the qualified powder moves through the magnetic separator, where any remaining magnetic impurities are removed to ensure a cleaner final material.

In the end, the final product is collected and either stored for later use or sent directly to the rubber powder bagging system for packaging and handling.
