The mine stones crusher (also known as a double-roll crusher) is a piece of equipment that excels in specific applications. If your crushing material is medium-to-low hardness brittle substances like limestone, pebbles, or coal, and you have high demands for uniformity of finished particle size, powder content, as well as energy consumption and operational costs, then the double-roll crusher is undoubtedly an efficient, economical, and environmentally friendly choice.

1.Working Principle

The working principle of the double-roll crusher is highly intuitive: two rolls rotate toward each other driven by an electric motor. Material enters the crushing chamber (V-shaped crushing chamber) formed between the two rollers from the top. It is subjected to continuous compressive and shear forces, crushed to the desired particle size, and finally discharged through the gap at the bottom. The size of this gap (i.e., the roll gap) directly determines the maximum particle size of the product and can be flexibly adjusted using a wedge device or shims.

2.Advantages

Excellent particle shape

Controllable particle size

Significant energy savings

Low noise and dust emissions

Lower investment costs
