Double Tooth Roller Crusher: High-Efficiency Solution for Sticky & Wet Materials

Intelligent Hydraulic Control & Superior Shear Crushing Performance

The Challenge: Handling Moisture, Stickiness, and Blockage

Double Tooth Roller Crusher

In industries such as coal mining, clay processing, and resource recycling, traditional impact or cone crushers often struggle with high-moisture and high-mud content materials. These conditions lead to frequent material adhesion, “bridging” in the crushing chamber, and costly downtime due to blockages. Furthermore, the inability to handle unbreakable foreign objects like iron scraps often results in severe mechanical damage.

The Solution: APEX Hydraulic Double Toothed Roller System

Our APEX Hydraulic Double Toothed Roller Crusher provides a robust solution by integrating advanced hydraulic intelligence with a unique “extrusion-shear-splitting” mechanism. Unlike traditional methods, this system handles materials through two counter-rotating toothed rollers, making it the industry standard for processing raw coal, bauxite, and construction waste.

• Intelligent Blockage Prevention: The self-cleaning tooth design naturally prevents buildup, ensuring stable operation even with wet and sticky ores.

• Automated Protection: An integrated hydraulic overload system senses unbreakable materials (e.g., iron), automatically retracting the rollers to clear the path and resetting without manual intervention.

• Low Rotation, High Torque: Reduces energy consumption by 15-25% while maintaining a high crushing ratio and throughput up to 300 t/h.

Tailored Engineering for Precise Output

Double Tooth Roller Crusher

Every project has unique requirements for particle size and material hardness. Our solution offers full customization of the toothed roller shape and length to match specific project scenarios:

Accurate Size Control: The discharge gap is hydraulically adjustable in real-time (8-200 mm depending on model), allowing operators to fine-tune output without stopping production.

Superior Particle Shape: The shear-based crushing process yields high-density, cubic particles with minimal needle-flake content—ideal for high-grade concrete and chemical applications.

Durable Material Science: Rolls are made from high-chromium manganese alloy, providing a service life 3-5 times longer than standard components.

Versatile Industry Adaptability

Whether it is raw coal in thermal power plants, limestone in the building materials industry, or refractory materials in the chemical sector, the APEX solution ensures uniform feed and stable quality. Its fully enclosed structure also ensures low noise and minimal dust emission, meeting global green mining and environmental standards.
