Abstract

The invention relates to the field of engineering construction, and discloses a sand making machine. The sand making machine comprises a feeding inlet (10), a dividing section (20) and an impeller section (30). The feeding inlet is used for downward feeding. The dividing section comprises a dividing part (21) and a plurality of feeding cavities (22), the dividing part is arranged below the feedinginlet and used for dividing materials entering from the feeding inlet into multiple groups according to the particle size and introducing into the inlets of the feeding cavities correspondingly, theoutlets of the feeding cavities extend to the different radial positions of the impeller section correspondingly, and the particle size of the materials in the feeding cavity, away from the center ofthe impeller section, of the outlet is larger than that in the feeding cavity, close to the center of the impeller section, of the outlet. According to the sand making machine, the materials with different particle sizes can be correspondingly accelerated to just the speed needed to be crushed, and thus the working efficiency and final crushing effect of the impeller section are improved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a sand making machine. Background technique [0002] Sand and gravel aggregate is the most widely used material in the field of construction. With the depletion of natural sand and gravel and the intensification of government environmental protection measures, natural sand resources are becoming increasingly depleted, and machine-made sand and gravel have become the mainstream of the sand and gravel aggregate industry. Currently, it is possible to figure 1 The shown vertical shaft impact crusher prepares sand and gravel, which mainly includes structures such as a feed port 10', a distribution plate 70, an impeller assembly 30', and a crushing chamber 80. When materials fall from the feed port 10', they can pass through the The plate 70 uniformly distributes the material along the circumferential direction, so that the material evenly enters the impeller assembly 30' and o...
