Full Wet Process Sand Making Technology for High-Purity Commercial Manufactured Sand

With the continuous improvement of construction engineering standards, high-purity zero-mud manufactured sand has become the mainstream demand of high-end concrete and municipal engineering markets. Dry-process sand making is easily affected by raw material mud and dust, resulting in excessive powder content and unqualified sand cleanliness, while traditional simple wet-process sand making has problems of serious fine sand loss, low output and large water consumption, restricting large-scale high-quality sand production.

The standardized full wet-process sand making system integrates multiple functions of crushing, shaping, washing, powder removal, fine sand recovery and dewatering, which completely solves the quality defects of traditional sand making processes. The core advantages of wet process lie in thorough mud and impurity removal and stable sand quality, which can completely remove surface soil, weathered layers and fine mud impurities of raw stones, ensuring the purity of finished sand.

SMP upgraded full wet-process sand making production line adopts three-stage crushing and multi-stage washing configuration. The VSI sand making machine completes particle rounding shaping, the high-pressure water washing system removes surface mud, the hydrocyclone fine sand recovery device captures lost fine sand, and the high-frequency dewatering screen reduces sand moisture content to the standard range. The whole process realizes automatic circulation and intelligent control, with high production efficiency and stable product quality.

The finished manufactured sand produced by this process has low mud content, reasonable fineness modulus, uniform particle size and excellent compactness, fully meeting the production requirements of high-strength commercial concrete, precast components and high-grade building projects. At the same time, the supporting sewage circulation system realizes water resource recycling, reducing water consumption and environmental pressure, realizing the dual advantages of high-quality production and green environmental protection.
