Quartz Sand Washing Equipment Process Selection Parameters: Building an Efficient and Clean Production System
Aug 05,2025
Processing Capacity (tons/hour): Directly determines equipment specifications and model selection.
Design maximum hourly throughput, average throughput, annual throughput.
Basis for calculating equipment volume, power, and auxiliary equipment (e.g., pumps, hydrocyclones).
Requires consideration of a fluctuation factor (1.1-1.3).
Cleaning Efficiency / Product Purity Requirements: Key final product specifications, determining the number of washing stages, equipment configuration, and operational intensity.
Content of <0.075mm (or <0.063mm) particles in finished sand (%): High-end applications demand extremely low levels (<0.1% or even <0.05%).
Maximum allowable content of specific impurities: Fe₂O₃, Al₂O₃, mica, etc.
Implication: Higher purity requirements necessitate more intensive processes: high-intensity attrition scrubbing + efficient multi-stage desliming (e.g., multi-stage hydrocyclones) + precise classification, and potentially chemical cleaning.
Product Moisture Content Requirement: Impacts drying costs and subsequent transportation/storage.
Maximum allowable moisture content (%) in finished sand.
Determines the selection of dewatering equipment (e.g., dewatering screens, dewatering hydrocyclones, filter presses, dryers) and their required efficiency.
