-Spiral Blade Conveyance: Rotating spiral shaft conveys sand upward along inclined trough bottom while counter-current water flow carries away light impurities and suspended solids
-Adjustable Overflow Weir: Vertically adjustable weir plate controls pool depth and sand retention time, enabling operators to optimize washing intensity for varying feed contamination levels
-Counter-Current Washing: Fresh water introduced at overflow end flows downward against upward-moving sand, creating efficient mass transfer that maximizes cleaning effectiveness
-Heavy-Duty Construction: Reinforced trough liner, oversized spiral shaft, and robust drive assembly handle abrasive sand loads and continuous 24/7 operation demands
-Alluvial Gold Mining: placer gold operations washing auriferous sand and gravel to remove clay bands and oxidized minerals before gravity concentration or cyanidation processes
-Silica Sand Processing: Industrial silica sand production for glass, foundry, and hydraulic fracturing applications requiring rigorous iron removal and grain size classification
-Railway Ballast Washing: Crushed stone ballast cleaning to remove fines and dust that impair drainage and track stability under dynamic train loading conditions
-Recycled Concrete Aggregate: C&D waste processing facilities washing demolished concrete fines from coarse aggregate fractions for reuse in new concrete production
-Continuous Operation: Uninterrupted feed and discharge suits high-volume production requirements without batch cycling delays inherent in some washing equipment designs
-Thorough Cleaning: Extended retention time and counter-current flow pattern ensure complete dispersion and removal of stubborn clay coatings and cementitious binders
-Abrasion Resistance: Hardfaced spiral blades and replaceable trough liners withstand years of processing highly abrasive quartz sands and crushed stone aggregates
-Simple Mechanical Design: Few moving parts and straightforward construction facilitate easy maintenance with commonly available tools and replacement components
