0-5mm Sand Portable Stone Crusher Machine 5TPH-200TPH Capacity

Portable stone crusher for producing 0-5mm crushed sand

1.Product Introduction Portable Stone Crusher

The Portable 0–5mm Sand Making Crusher is a specialized mobile plant designed to meet the growing demand for "manufactured sand" (M-Sand) as a sustainable alternative to river sand. Producing high-quality fine aggregate (0–5mm) requires a different mechanical approach than standard stone crushing; this unit utilizes Vertical Shaft Impact (VSI) technology or high-speed Fine Cone Crushing. By applying high-velocity centrifugal force, the machine shapes the particles into a cubical form while removing internal fractures. This portable solution allows operators to produce premium-grade concrete and mortar sand directly at the source, whether from quarry "waste" or virgin rock.

2.Application Portable Stone Crusher

• Manufactured Sand (M-Sand) Production: Converting 10–40mm aggregates or "crusher dust" into premium 0–5mm sand for high-strength concrete.

• Dry Mortar Industry: Producing the precise, fine-grained sand required for tile adhesives, plasters, and masonry mortars.

• Glass and Ceramic Raw Materials: Fine crushing of silica sand and feldspar with high purity and consistent gradation.

• Tailings Reprocessing: Transforming mining waste into usable construction sand, reducing environmental footprints and waste storage.

3.Working Principle Portable Stone Crusher

• Rock-on-Rock Attrition: Most sand-making units use a VSI (Vertical Shaft Impact) mechanism. Material enters through the top and is accelerated by a high-speed rotor, then hurled against a "rock lining" in the crushing chamber.

• Centrifugal Shaping: The high-velocity impact causes the stones to collide with each other, breaking off sharp edges and creating a cubical, rounded particle shape similar to natural river sand.

• Integrated Air Classification (Optional): Many portable units feature an on-board air separator or a high-frequency vibrating screen to precisely control the "fineness modulus" and remove excess ultra-fine dust (silt).

• Closed-Circuit Operation: Oversized material is automatically recirculated via a return conveyor back into the crusher until it meets the 5mm threshold, ensuring 100% production efficiency.

4.Advantages Portable Stone Crusher

• Superior Particle Shape: Unlike traditional "crusher dust" which is often flaky, this machine produces cubical sand that improves the workability and strength of concrete while reducing cement consumption.

• Adjustable Fineness Modulus: Operators can fine-tune the output by adjusting the rotor speed or the cascading feed ratio, allowing for the production of everything from coarse concrete sand to fine plastering sand.

• Highly Mobile and Compact: The entire plant—including the crusher, screens, and conveyors—is mounted on a single chassis, making it easy to move between projects or reposition within a quarry.

• Reduced Wear Costs: The "rock-on-rock" principle means the rock itself acts as the wear liner for much of the process, significantly extending the lifespan of expensive metal components.

• Environmental Compliance: Equipped with advanced sealing and dust collection systems to meet strict air quality standards in urban or sensitive environments.
