DDC-Sizers McLanahan

The crushing rolls can be rotated either inward or outward at slow speed and high torque, which minimizes slippage and fines generation. Slow-speed DDC-Sizers are selected for the specific material and lump size to be crushed. Tooth profile selection allows the material to be grabbed and pulled into the crushing zone for maximum efficiency.
