[0002] Machine-made sand is a type of gravel material produced by mechanically crushing rocks, ores, or other materials. Compared to natural sand, the production process of machine-made sand is more controllable, and the particle shape, particle size distribution, and composition can be adjusted according to demand, making it widely used in construction and engineering. During the production and use of machine-made sand, it needs to be screened to remove large particles while collecting small particles for further use. A machine-made sand separator is required in the production of machine-made sand, but existing machine-made sand separators still have certain defects; for example:

A screening box connected to the screening tank through a pipe is welded on the top outer wall of the pillar, and a feed hopper that penetrates the screening box is inserted on one side of the top outer wall of the screening box. Motor No. 2 is installed on one side of the top outer wall of the screening box by bolts, and the output shaft of motor No. 2 is installed with a rotating shaft through a coupling. The stirring paddle of the utility model can stir the machine-made sand, and the magnetic rod will attract the magnetic material in the machine-made sand, thereby filtering the machine-made sand, which is beneficial to improving the production quality of the machine-made sand; at the same time, the screens with different mesh diameters between the mounting plates can screen the machine-made sand in the screening tank into a variety of particles, which can achieve the function of multi-layer screening, thereby facilitating the screening box to screen out better machine-made sand. According to the above, although this machine-made sand separator can be used very well, when sorting machine-made sand, the raw materials cannot be poured out at the same time by adjusting the angle of the sorting drum. The raw materials are easily blocked when screening inside the equipment, which increases the labor burden of the user, and the equipment cannot replace the size of the screening drum according to the size of the machine-made sand required by the user. The equipment has low flexibility and often troubles the user. Utility Model Content
