Description

Technical Field

[0001] The utility model relates to the technical field of sand making equipment, in particular to an impact sand making machine. Background Art

[0002] Sand is a common building material, primarily used in the preparation of concrete and mortar. However, sand mining is prohibited in most areas, leading to a growing demand for manufactured sand. This has stimulated the development of the manufactured sand market and attracted a large number of investors to invest in sand making equipment. Although there are many types of sand making machines on the market, the technology is still relatively backward. This is not only a waste of sand and gravel resources, but also a damage to the environment.

[0003] Existing sand production technology involves conveying aggregate to a crushing machine through a conveyor system. The crushed aggregate is then conveyed to a vibrating screen, creating a closed-loop, multiple-cycle system. This achieves continuous crushing, and the aggregate that meets the required particle size is then discharged via a conveyor, achieving production goals. However, the following drawbacks exist: 1) During aggregate crushing, screening, and conveying, dust is emitted, which is detrimental to the atmospheric environment and requires a dedicated dust removal system. 2) Depending on the sand production method, the sand production process can consume significant amounts of water, with approximately 2 to 3.5 tons of water consumed per ton of aggregate, increasing production costs and environmental pressures. 3) The equipment requires a large foundation and complex supporting facilities, requiring sewage treatment facilities and significant production space. 4) Consumable parts of the sand making machine, such as hammers, plate hammers, and liners, wear out over extended periods of operation, requiring regular replacement, increasing maintenance costs. 5) Raw materials with high humidity or moisture content can affect production efficiency and product quality. Therefore, improvements to existing sand production equipment are necessary to address these issues. Summary of the Invention
