With the continuous progress of construction, a large number of sand and gravel aggregates are required for highway construction projects, water conservancy and hydropower projects, and urbanization construction projects. The national policy restricts the exploitation of natural sand and gravel aggregates. The traditional sand and gravel materials gradually fade out of people's vision due to rising prices, increased transport costs and unstable quality.
The machine-made sand has come into the public's view because of its advantages such as uniform stage matching, low crushing value, moderate stone powder content, and stable performance. It is expected to become a key investment object. The production line of dry manufactured sand and the complete set of equipment for dry manufactured sand follow the trend.
According to the market demand, SMMVIK Machinery has enriched the sand production process with energy-saving and economical crushing and powder selection technologies. Through the demonstration and experiment of the whole process, it has launched the VU series dry machine made sand production line.
The complete set of dry sand production equipment uses the cheaper 5-100mm stones from the stone factory as raw materials, which can process the low price stones into machine-made sand, turn waste into treasure, and create income and efficiency, Bring new economy to concrete mixing plant or sand and gravel plant. The dry sand making system solves the production problem of machine-made sand with a new dry sand making scheme, creating new opportunities for the development of the sand and cement industry chain.
Dry manufactured sand production line has the following advantages:
1. The finished sand is of high quality. The size of the stone is 0-13mm. After the impact shaping of the sand and stone system, high-speed grinding and the selection of the grain optimizing machine, the finished sand and stone have high density, less water absorption, good grain size, high solid volume, round surface, and uniform thickness. The grading, grain type and powder content of sand are more reasonable, the fineness modulus is 2.5-3.2, and the powder content is 3-15%, which can be adjusted at will.
2. Environmentally friendly. The fully closed and negative pressure process design ensures that the dry manufactured sand production line system does not produce dust during operation, while the dry process production does not require water washing, and the production process does not produce sewage sludge treatment problems.
3. The comprehensive cost is low and the economic benefit is good. The VU dry manufactured sand production line has been optimized by the digital scientific and technological personnel of SMMVIK Machinery, which has solved the problem of insufficient technology of the traditional sand production line, making the comprehensive investment cost lower than the traditional sand production equipment, with high output, superior performance and good economic benefits.
