Description

Technical Field

[0001] The present application relates to the technical field of pure machine-made sand, and in particular to a sand making machine for preparing pure machine-made sand concrete. Background Art

[0002] Pure machine-made sand refers to the process of breaking hard rocks and ores into fine sand particles through a series of crushing and grinding processes. These sand particles are generally used in construction, roads, bridges and other civil engineering projects to increase the strength and durability of concrete. The production process of pure machine-made sand includes several steps: first, large pieces of rock or ore are fed into the crusher for preliminary crushing, and then these small particles are fed into the sand making machine for further crushing and sand making, and then fine sand particles are produced.

[0003] At present, in the process of preparing concrete, a sand making machine is needed to further crush and make sand for the granular rock or ore, so as to produce fine sand particles. However, when the granular rock or ore is fed into the current sand making machine, the granular rock or ore is usually directly put into the feed hopper, and the storage space for the granular rock or ore in the feed hopper is limited, and it is difficult to continuously feed it. Frequent manual feeding is required, which increases the labor intensity of workers during sand making. Therefore, in order to solve the above problems, we provide a sand making machine for the preparation of pure machine-made sand concrete. Utility Model Content
