The Usability of Crushed Stone Sand
Crushed stone sand is produced by breaking down hard rocks such as granite, basalt, and river pebbles into fine particles through a crushing process. This type of sand has several advantages that make it highly usable in various construction applications.
High Strength and Durability
Crushed stone sand is known for its higher compressive and flexural strength compared to natural sand. The angular and cubical shape of the particles provides better interlocking, resulting in improved durability and longevity of concrete structures . This makes it an excellent choice for high-strength concrete used in bridges, dams, and tall buildings.
Consistent Quality and Grading
Unlike natural sand, which can vary in quality and grading, crushed stone sand can be precisely manufactured to meet specific particle size distributions. It can be produced in various grades such as coarse sand (0.5 mm–1 mm), medium sand (0.25 mm–0.5 mm), fine sand (0.125 mm–0.25 mm), and extra fine sand (0.0625 mm–0.125 mm) . This consistency ensures uniform performance in construction materials.
Environmental Benefits
The production of crushed stone sand helps reduce the environmental impact associated with river sand mining. It minimizes riverbed erosion, prevents changes in water pH levels, and conserves natural resources . Additionally, it can be produced locally near construction sites, reducing transportation costs and carbon emissions.
Cost-Effectiveness
Although the initial production cost of crushed stone sand may be higher than natural sand in some regions, its long-term benefits make it cost-effective. The consistent supply and reduced transportation costs contribute to overall savings in large-scale construction projects.
Best Machines for Crushing Stones into Sand
Selecting the right machine is crucial for efficient and high-quality sand production. Different types of crushers and sand-making machines are available, each with its own advantages and applications.
VSI sand making machine
VSI series sand making machine is a high-performance sand making equipment in the industry. It is the main equipment in the field of artificial sand making machine and stone shaping. The output of a single machine can reach 50-650t/h, and it has both sand making and shaping functions. The fine sand and gravel processed by it have uniform particle size and high gradation, which can meet the requirements of sand in various fields of the market. Not only that, it is also environmentally friendly and can easily achieve dust-free operation, helping users to easily pass environmental impact assessment!
2 Roller sand making machine
Roller sand making machine is mainly composed of rollers, roller support bearings, drive devices and adjustment devices. The material is crushed by the adjustment device between the roller and the drive machine. It is suitable for medium and fine crushing of ores and rocks below medium hardness. Compared with other sand making machines, it has low consumption and good sand particles, but because of its low output, it is mostly used in some small and medium-sized sand and gravel plants.
3 Mobile sand crusher
Mobile sand crusher, also called mobile sand making machine, is different from fixed sand making machine in that it can be moved freely and is not restricted by external conditions such as site and environment. It breaks the embarrassing situation of traditional fixed sand making operation. It adopts an integrated whole set of unit design, can be directly driven to the work site and put into production quickly, and its working efficiency is 40%-60% higher than that of fixed equipment. Of course, in terms of price, it is definitely more expensive than fixed sand making machine, but this does not affect the boss's love for it!
