20 ton per hour gold ore rock double roller crusher machine

The roll crusher machine can be classified into single roll crusher, double roll crusher, and four-roller crusher according to the roller quantity. Double roll crusher, also known as toothed roll crusher, is the most commonly used. Based on the roller speed, roll crusher machine is laid in high-speed roll crusher, low-speed roll crusher, and differential-speed roll crusher.

Working principle

The main parts of roll crusher are two rollers, one fixed roller and one movable roller. The two rollers are driven by wheels and belts. When the roll crusher machine works, the movable roller is pushed by the spring between the body and wheel to rotate forth and back. Materials fed by the vibrating feeder fall between the two rollers and get squeezed and crushed. Qualified particles will through the teeth on the rollers and are exhausted out.

Product advantages

• Large crushing ratio. When a larger crushing ratio is needed, a crushing stick-shaped device can be equipped under the rollers to adjust the crushing ratio.
• Simple structure. The modularized frame allows roll crusher to be installed at your place or to have a grouped installation.
• Low over-crushing rate. Roller crusher machine adopts a combined crushing mode, not impaction, which avoids a second crushing in the body.
