I. Product Positioning

An economical, high-precision dry‑sorting equipment specially designed for powder materials, focusing on the fine classification of dry mineral powders in the 16–150 mesh range. It features an ultra‑simple structure, exceptionally low energy consumption, outstanding stability, and virtually zero maintenance requirements, serving high‑purity sand and slab‑sand processing plants as well as non‑metallic mineral powder production lines. Key advantages: dry powder sorting, chute‑type discharge, high precision, low energy use, and cost‑effective durability.

II. Application Scenarios

● High-purity quartz sand / plate sand: In the dry state, particle size ranges from 16 to 150 mesh; black spots, yellow skins, discolored particles, and gangue are removed, boosting whiteness to over 98% and meeting the stringent quality standards for high-end photovoltaic and glass applications.  
● Calcite/Dolomite Powder: Dry‑state purification, with controlled whiteness and impurity levels, for use in building materials, chemical fillers, and plastic masterbatches.  
● Other mineral powders: Dry‑state sorting and purification of alumina powder, talc powder, gypsum powder, polymeric materials, and other substances.  
● Dry separation environmental requirements: Material moisture content ≤ 2%; ambient temperature −10°C to +45°C; relative humidity ≤ 85% (no condensation). Compatible with dry‑process production lines, suitable for water‑scarce or environmentally sensitive areas, with zero wastewater, low dust generation, and reduced energy consumption.
