Double teeth roll crusher is mainly used in mining, metallurgy, chemical industry, coal mine to crush coarse, medium size fragile material. Its feeding size is big, discharging size is adjustable. it can crush material of compressive strength below 160Mpa.

Especially in coal industry, double teeth roll crusher can crush raw coal and coke directly after removing iron and impurity, no need to remove gangue. crushed material is uniform granularity, low over crushing ratio. it simplified coal selecting process, reduced investment and production cost. Double teeth roll crusher can be equipped with coarse or medium sized teeth rollers according to material characteristics and requirements.

Working principle

The double-toothed roller sand making machine uses two wear-resistant alloy toothed rollers to break materials under high extrusion pressure generated by relative rotation. After the materials enter the gap between the two toothed rollers (V-shaped crushing chamber), the materials are broken into the required particle size and then sent out by the conveying equipment under extrusion, shearing and grinding.
