Detailed description of the invention

Below the specific embodiment of the present invention is described; so that those skilled in the art understand the present invention; but should be clear; the invention is not restricted to the scope of detailed description of the invention; to those skilled in the art; as long as various variations appended claim limit and definite the spirit and scope of the present invention in, these variations are apparent, all utilize innovation and creation that the present invention conceives all at the row of protection.

The double-cavity crushing machine for sand processed as shown in Figure 1, comprises the charging aperture 1, the first crusher chamber 2, the second crusher chamber 3 and the 3rd discharging opening 4 that are communicated with successively. In the first crusher chamber 2, be provided with in the first broken rotor 21, the second crusher chamber 3 and be provided with the second broken rotor 31; Included angle A between axial line plane and the horizontal plane of the first broken rotor 21 and the second broken rotor 31 is 10 °. In addition the below that, the bottom of the first crusher chamber is provided with the first sieves 22, the first sieves 22 is provided with the first discharging opening 23; The below that the bottom of the second crusher chamber 3 is provided with the second sieves 32, the second sieves 32 is provided with the second discharging opening 33.

Building stones enter the first crusher chamber 2 and the second crusher chamber 3 successively by charging aperture 1, first by the first broken rotor 21 in the first crusher chamber 2, building stones are carried out to coarse crushing, carrying out in small, broken bits by the second broken rotor 31 in the second crusher chamber 3 to building stones, improve crushing efficiency, made particle size after cracking reach sand requirement processed. Becoming in product process, also can carry out discharge to the finished product that meets the requirements of in the first crusher chamber 2 and the second crusher chamber 3 in time, can avoid occurring in production process the phenomenon of obstruction.
