Dual-chamber rotary crusher is a new alternative to thin broken jaw, cone crusher broken ore in the mineral processing industry market promising. Parts of their work is a high-speed rotation of the crushing roller, the roller set with a pair of symmetrical curved broken board composed of two coupled optimization of the crushing chamber clamp material good, the spindle under the action of crushing roller eccentric horizontal rotary pendulum movement to do, thus producing strong circulation squeeze pressure, continuous, progressive for the two alternating materials in the crushing chamber for crushing, the product from the two discharge ports continue to discharge.Widely used for metal and nonmetal ores, construction chemicals, cement clinker, refractories, etc. 60 MPa compressive strength following various rock and mineral materials, the crushing and super fine crushing coarse grinding jobs.
