Facing the problems of unreasonable grading, excessive powder and mud content, and substandard particle shape of traditional machine-made sand and gravel in the market, Shibang Group has created a tower-type high-quality machine-made sand and gravel processing system, overcoming the difficulties of crushing, grinding and selecting in the optimization process. The quality of the finished sand and gravel produced meets national standards, and the production process has zero silt, zero wastewater, and no dust, which fully meets national environmental protection requirements, bringing huge benefits and development opportunities to industries such as sand and gravel, dry mixing, commercial mixing, pipe piles, and cement products.
The grinding technology and waterfall shaping technology adopted by the tower sand making system make the finished sand and gravel grading reasonable and the grain shape round, effectively reducing the specific surface area and porosity of coarse and fine aggregates; at the same time, the dry powder removal technology is adopted to make the powder content in the finished sand adjustable and controllable.
The amount of sand and gravel is large and the demand is high, and the VU building station type machine-made sand and gravel complete system can process cheap and easily available “stone chips” and “melon stones” into high-value high-quality sand, replacing natural sand, meeting the huge market demand for high-quality sand, and making huge profits.
The tower-type machine-made sand and gravel complete system adopts fully enclosed transportation, production, and negative pressure dust removal design to ensure that there is no sewage, no sludge, no dust and noise emissions in production, which fully meets the national environmental protection requirements.
The tower-type machine-made sand and gravel system is equipped with a central control system, which can control and detect the operation of all equipment online, quickly set and maintain outstanding operating parameters, and ensure the quality of finished sand and gravel and the stability of production line capacity.
The tower sand making system includes equipment and modules such as impact crusher, mold-controlled screen, particle optimization machine, humidifying mixer, dust collector, central control system, steel structure, etc., which is a complete set of dry sand production solutions. Raw materials below 15mm (which can be cheap and easily available raw materials such as stone chips, melon stones, stone powder, etc.) are crushed and shaped by impact crusher, and then divided into three ways under the action of mold-controlled screen and dust removal module: stone powder, return material and semi-finished sand. After passing through the dust removal module, the stone powder is uniformly stored in the powder ore bin, and the semi-finished sand enters the particle optimization machine for further shaping, and the processing process is completed after humidification and mixing. After the raw materials are rationally and efficiently processed by the tower sand making system, high-quality machine-made sand with reasonable grading, rounded particle shape and controllable powder content is produced, as well as dry and clean high-quality stone powder that can be uniformly recycled (the scope of application is determined by the raw materials).
In the construction aggregate industry, SBM mainly provides jaw crushers, impact crushers, cone crushers, sand making machines, mobile crushers and other crushing equipment to meet customers' production needs of different tonnages and sand and gravel aggregates.
