Background

The cement is a powdery hydraulic inorganic cementing material, is added with water and stirred into slurry, can be hardened in air or water, and can firmly cement materials such as sand, stone and the like together. When the cement is processed, stones with large volume (the block diameter is more than 20 cm) or medium volume (the block diameter is between 5cm and 20 cm) need to be crushed into stones with small volume (the block diameter is less than 5cm) so as to be ground, and stones with large volume need to be firstly crushed into stones with medium volume and then can be crushed into stones with small volume. But when haulage vehicle transported building stones to the processing factory, the volume of building stones was not of uniform size, consequently need to filter the building stones of transporting, the crushing is sent to the great building stones of volume, the less building stones of volume directly carries out the crocus, and now to the screening of cement processing building stones, screen with the sieve, and the less building stones of volume can be selected to the sieve, but the great building stones of volume and the building stones that are in the equal volume are mixed together, if not subdividing it, the building stones with two kinds of volumes together carry out the breakage, step repetition then can appear to the equal volume building stones in the well, not only extravagant manpower, and long to the processing process of cement, inefficiency.
