With the construction of high-speed railways, highways, nuclear power plants, and high-rise buildings in China, ordinary aggregates can no longer meet the raw material demands of high-performance concrete. As a result, the demand for high-quality aggregates has increased, and good sand-making equipment is essential. The production process of high-quality aggregates generally consists of pre-processing, crushing, sand-making, screening, and sand washing (or powder selection) stages. Common crushing equipment includes JC jaw crusher, GPY cone crusher, PFQ impact crusher, etc., which process ores to below 50mm for further sand-making. The key to processing high-quality manufactured sand lies in the sand-making machine. There are various types of sand-making machines available in the market, each with different technologies, principles, and particle size outputs. Below, we provide a detailed introduction to sand-making machines.
PLS Vertical Impact Sand-making Machine
The PLS vertical impact sand-making machine offers high cost-effectiveness and is one of the best-selling equipment in the market. It excels in producing high-quality sand with high efficiency and performs both sand-making and shaping functions. The finished products are of excellent quality. With a deep-cavity impeller design, it increases the throughput of stones by over 30%. The sealed chamber design reduces the impact of dust and noise, achieving true environmental friendliness.
Mobile Sand-making Machine
The "movable" sand-making production line allows the entire sand plant to be supported by a single device, or multiple devices can be connected for high-volume sand production. It comes in both crawler and tire types, enabling flexible operation in various sand plants. The production efficiency is remarkably high, making it suitable for areas with widely distributed materials or strict environmental regulations.
The mobile crushing machine eliminates the cumbersome steel frame structure and foundation construction during the crushing process, saving a significant amount of time. It offers a variety of personalized unit configurations based on customer requirements and actual conditions. It can operate as a single unit or in combination with multiple units, enabling single-unit crushing, multi-unit grading, screening, and other functional combinations.
Excellent manufactured sand production processes and appropriate equipment selection are crucial for ensuring the quality of manufactured sand, which directly impacts the quality of concrete. Choosing poor-quality sand-making equipment can result in higher maintenance and repair costs, as well as disruptions in sand production. Therefore, it is important to pay attention to the quality of the equipment when selecting sand-making machinery.
