Processing wet and sticky materials like construction waste, phosphogypsum, or wet coal often leads to frequent clogging in traditional impact or hammer crushers due to their reliance on bottom screens. The Teeth Roll Crusher solves this nightmare with a “Non-Clogging” design. Its core advantage is a screen-less structure where output size is controlled by the physical gap between rollers, allowing wet mud and oily materials to pass through freely.

Operating at low speeds (80–150 RPM), it prevents materials from sticking to the chamber walls due to centrifugal force or frictional heat. Furthermore, customizable tooth shapes (such as V-grooved or comb teeth) can “comb through” clumps of phosphogypsum or wet coal. Real-world cases, such as a chemical base in Hubei with 25% moisture phosphogypsum, show that switching to a double-teeth roll crusher enabled 72 hours of continuous operation without downtime. While not suitable for liquid slurry (moisture > 30%), the Teeth Roll Crusher is the optimal solution for handling complex, sticky solid waste where others fail.
