  • Direct milling from 5-30 mesh input to 40-120 mesh output

  • Advanced tungsten carbide milling discs for extreme durability

  • Built-in circulating water cooling system prevents material degradation

  • Ideal for high-volume, continuous production facilities


The Rubber Powder Fine Miller represents the pinnacle of modern particle reduction technology, engineered specifically to address the rigorous demands of large-scale rubber recycling and processing facilities. When you stand beside this robust machinery, the steady, low-decibel hum of the 30kw main motor conveys immense grinding power, operating with a smooth, vibration-free stability that speaks to its precision engineering. The heavy-duty 1.5-ton steel frame is coated in a durable, industrial blue finish, providing a sleek yet rugged appearance that withstands the harshest production environments.

Inside the milling chamber, the raw 5 to 30-mesh rubber particles are met with the relentless shearing force of fixed and rotary milling discs. Instead of the acrid smell of scorched rubber often associated with inferior grinders, the air remains remarkably clean and odor-free. This is achieved through the sophisticated internal circulating water cooling system, which maintains an optimal ambient temperature. The resulting output is a remarkably soft, uniform, and highly active 40 to 120-mesh black rubber powder that feels almost like fine sand running through your fingers. Every component, from the frequency conversion feeder to the precision motor adjusting device, is seamlessly integrated to ensure your production line operates flawlessly, maximizing yield while preserving the essential elastomeric properties of the rubber.

Key Features & Highlights

Achieving superior output quality requires machinery that goes beyond basic functionality. Our fine miller is meticulously engineered to provide exceptional operational advantages, ensuring your production facility remains competitive and highly profitable.

  • Exceptional Milling Durability: The core milling surface utilizes premium tungsten carbide, a material renowned for its extreme hardness and crashing-proof characteristics. This ensures the discs remain wearable and durable over extended operational periods, drastically reducing the frequency of replacement parts.

  • Thermal Protection Technology: The integrated internal circulating water cooling system is a game-changer. It actively regulates the temperature of the milling discs during high-speed friction, guaranteeing that the rubber powder never gets burned, sticky, or degraded.

  • Precision Feed Control: Equipped with a state-of-the-art frequency conversion feeder, the equipment allows operators to fine-tune the material intake with absolute precision. This prevents overloading and ensures a consistent, uniform grind from start to finish.

  • Robust Structural Integrity: The machine frame and main shaft are constructed from specially treated, heavy-duty materials that offer excellent ductility and vibration absorption. This solid foundation minimizes mechanical wear and ensures quiet, stable operation.

Comprehensive Operational Advantages

To truly understand the value this equipment brings to your processing facility, it is essential to examine its multi-dimensional capabilities. Every aspect of the machine has been optimized to enhance your production efficiency and end-product quality.

  • Output Fineness & Application: This system effortlessly reduces 5-30 mesh rubber granules directly into a premium 40-120 mesh fine powder. This high-purity, ultra-fine output is highly sought after for manufacturing plastic tracks, modified asphalt, recycled rubber sheets, and premium rubber fillers, allowing you to easily penetrate high-value markets and increase your profit margins.

  • Temperature Control & Cooling: Heat is the enemy of rubber processing. By utilizing a highly efficient built-in circulating water cooling system, the machine strictly controls the temperature of the milling discs during high-speed rotation. This completely resolves the industry pain point of rubber scorching, melting, or agglomerating during normal-temperature grinding, fully preserving the physical activity and superior quality of the powder.

  • Material & Durability: The grinding surface of the milling disc is forged from Tungsten Carbide, a high-wear-resistant alloy, while the base undergoes specialized metallurgical treatments. This grants the equipment outstanding impact resistance, wear resistance, and high ductility, significantly extending its service life and lowering your long-term maintenance and consumable costs.

  • Capacity & Energy Efficiency: Designed for maximum output with minimal footprint, a single unit delivers a stable production capacity of 65-200 kg/h. The scientifically configured power train (30kw + 7.5kw + 3kw) ensures high-efficiency pulverization at low energy consumption levels, offering an exceptional return on investment for your facility.

  • Automation & Operation: The integration of a frequency conversion feeder and a precision motor adjusting device allows for the stepless regulation of feeding speeds and milling disc gaps based on specific material properties. This intelligent operation lowers the barrier to entry for operators, reduces reliance on manual labor, and ensures unwavering production stability.

  • Environmental & Dust Control: Maintaining a clean facility is paramount. The equipment features a professional collecting pipe system and a fully enclosed grinding structure. This effectively captures the finished product and prevents any dust or micro-fibers from escaping into the air, creating a clean, pollution-free green production environment that easily meets strict environmental compliance standards.

Frequently Asked Questions (FAQ)

Navigating the technical aspects of fine rubber milling can raise several important questions. Below, we address the most common inquiries to help you make an informed purchasing decision.

How does the internal water cooling system prevent the rubber from degrading?

The internal circulating water cooling system continuously flows cold water through specialized channels within the milling discs and chamber. This rapidly dissipates the intense heat generated by high-speed friction, keeping the ambient temperature well below the melting or scorching point of rubber. Consequently, the powder retains its original physical properties and active characteristics without becoming sticky.

What is the expected lifespan of the tungsten carbide milling discs?

Tungsten carbide is one of the hardest and most wear-resistant materials available for industrial milling. Under normal operating conditions and with proper maintenance, these discs offer a significantly extended lifespan compared to standard steel alloys. The exact duration depends on the volume and purity of the input material, but operators typically experience drastically reduced replacement frequencies, lowering overall consumable costs.

Can the output fineness be adjusted during operation?

Yes, the output fineness can be precisely controlled. The machine is equipped with a sophisticated motor adjusting device that alters the clearance gap between the fixed and rotary milling discs. Combined with the frequency conversion feeder that regulates the material intake speed, operators can easily fine-tune the system to produce specific grades of powder ranging from 40 to 120 mesh.

Does the equipment require a specialized foundation for installation?

While the machine boasts a robust 1.5-ton weight, its heavy-duty machine frame and balanced main shaft are designed to minimize vibration. A standard, level industrial concrete floor is generally sufficient for installation. However, we provide detailed layout and foundational guidelines to ensure optimal stability and noise reduction in your specific facility.

How does the dust collection system ensure a clean working environment?

The grinder features a fully enclosed milling chamber connected to a high-efficiency collecting pipe and cyclone separation system. As the fine powder is generated, it is pneumatically drawn into the collection agency, preventing micro-particles and rubber fibers from escaping into the ambient air. This closed-loop design ensures compliance with strict environmental and occupational health standards.
