Double Tooth Roller Crusher

Traditional crushers, such as jaw or cone types, rely on high-pressure compression. This often backfires with wet coal or clay, as the pressure turns the material into a compacted “cake” that blocks the chamber. HSM’s Hydraulic Double Tooth Roller Crusher operates on a completely different principle: Active Shear and Tensile Splitting.

Engineering features that eliminate clogging:

• Anti-Adhesion Tooth Profile: The rollers feature a staggered tooth arrangement. As they rotate in opposition, the teeth act like a mechanical comb, stripping away potential buildup before it can bond to the roller surface.
• Mechanical “Grip & Pull” Action: Instead of waiting for gravity, the sharp toothed profiles actively bite into the raw material and force it through the crushing zone. This mechanical drive effectively handles the high internal friction of mud and silt.
• Screen-Free Sizing Control: Most blockages happen at the discharge screen. Our system controls final product size through the precise gap between the rollers, allowing moisture-heavy fines to exit immediately without being trapped by a sieve plate.

Technical Note: For extreme conditions, such as 15%+ moisture bauxite or tropical clay, HSM offers custom-engineered “long-tooth” configurations to ensure consistent 24/7 operation during peak rainy seasons.
