Description

Technical Field

[0001] The invention belongs to the technical field of building material processing equipment, and in particular relates to a sand and gravel crushing and shaping machine. Background Art

[0002] The key to producing high-performance concrete lies in the sand and gravel. However, since artificial sand and gravel entered the concrete market, they have been questioned due to their rough particle shape, sharp edges, high fineness modulus, unreasonable gradation or high mud content. Among them, the gradation problem can be solved by matching with natural fine sand, high mud content can be washed before or after crushing, and the stone powder content can be controlled in the feeding stage. Finally, the only problem left is the particle shape, which is more difficult to solve.

[0003] In the supply of raw materials for concrete engineering, concrete producers prefer to obtain spherical sand and gravel particles, because spherical sand and gravel particles are conducive to the compact accumulation of concrete and the performance of concrete work. Spherical aggregates can also exert the linkage rolling effect of slurry and aggregate. At present, the existing sand and gravel production line can only use professional crushers to crush sand and gravel first, and then use special shaping machines to shape the shape of sand and gravel particles after the sand and gravel are crushed, so as to achieve the spherical sand and gravel particles that concrete producers prefer. Therefore, designing an integrated device that can crush and shape sand and gravel at the same time has become a technical problem to be solved. Summary of the invention

[0004] The present invention provides a sand and gravel crushing and shaping machine, which optimizes sand and gravel crushing and sand and gravel shaping into one. Sand and gravel are crushed on the upper side of the crushing and shaping cavity. The crushed sand and gravel are transported from the center of the auxiliary guide plate to the sand and gravel shaping impeller through the guide baffle and the guide plate ring, and then discharged through the discharge port. The crushing and shaping of sand and gravel are completed at one time by one device. The crushed and shaped sand and gravel particles are all spherical sand and gravel particles, which improves the production efficiency of the sand and gravel production line, reduces the production process, and reduces the production cost.
