INDUSTRIAL HIGH-PRESSURE GRINDING

Double Tooth Roll Crusher

High-Torque Shearing | Anti-Clogging Design | Handles Wet & Sticky Materials

Discharge Size: 10mm – 200mm Adjustable

Double Tooth Roll Crusher is a rugged, high-capacity crushing solution that uses low-speed, high-torque shearing and tearing action to process medium-hard and sticky materials. By rotating two toothed rolls in opposite directions at differential speeds, it pulls material into the crushing cavity and fractures it along natural cleavage planes – preventing over-crushing and reducing fines generation. This makes it an ideal choice for coal, coal gangue, bauxite, and construction waste recycling.

Double Tooth Roll Crusher: Why Choose It for Your Plant?

• Shear‑Dominant Crushing Action – Material is ripped and torn rather than compressed, producing cubical particles with minimal powder. This double tooth roll crusher handles feed sizes up to 1050 mm in a single pass.

• Anti‑Clogging Tooth Geometry – Self‑cleaning tooth arrangement prevents wet, clay‑rich material from adhering to roll surfaces, ensuring continuous operation even at 30% moisture. The double tooth roll crusher maintains steady throughput without clogging.

• Customizable Tooth Profiles – Choose from wolf teeth, wave teeth, or sharp teeth to match your specific material hardness, feed size, and output requirements.

• Hydraulic / Spring Overload Protection – When an uncrushable object (tramp iron, rock bolt) enters, the roll gap automatically widens to let it pass, then resets instantly – no downtime, no damage.

• Segmented Roll Discs – Each roll is assembled from individual, replaceable disc segments. Worn discs can be changed on site without lifting the entire roll assembly, cutting maintenance time by 70%.

• Low Fines Generation – The low‑speed shearing action keeps -6 mm fine powder below 15%, improving downstream separation efficiency for jigging or heavy media processes. This double tooth roll crusher delivers superior particle consistency.
