Abstract
A double-cavity rotary jaw crusher is characterized in that an eccentric rotary jaw roller and two ratchet-tooth-shaped concave fixed jaw plates which are bilaterally symmetrical are coupled to form double crushing cavities, and each crushing cavity has the characteristic of changing the sectional engagement angle, so that the efficiency of the crusher is improved, and the smooth discharging is ensured. The eccentric rotary jaw roller moves along with the eccentric position to crush the materials in the double cavities in sequence, which is the key for adapting to large crushing ratio and saving energy. Because the double crushing cavities are adopted for working, the length of the discharge opening is doubled, excellent conditions are created for fine crushing, the production capacity is improved by nearly one time compared with that of a single-cavity machine, and the energy consumption can be reduced by about 60 percent according to the calculation of the production rate, so that the double-cavity energy-saving crusher is a high-efficiency energy-saving crusher suitable for large crushing and fine crushing.
