IntroductionFG Spiral Classifier is a common mineral processing equipment. It uses the principle that solid particles of different sizes and densities have different settling velocities in a liquid. It can be paired with a ball mill to form a closed-circuit circulation, performing operations such as ore particle size classification, desliming, and dehydration.
Applications
- Mineral Processing (Closed-circuit Grinding): Often paired with a ball mill, it forms a closed-circuit circulation system. Coarse materials (sand returns) are sent back to the mill for further grinding, while fine materials meeting the requirements overflow, forming the final product.
- Sand Washing and Aggregate Industry: Used to wash, classify, and dewater sand and gravel, removing soils and impurities to meet the standards for construction and road materials.
Classification and Desliming in Gravity Concentration: In gravity concentration operations, it is used to classify ore and fine mud, remove fine slime (desliming), and prepare materials for subsequent processes like flotation or gravity separation.
Features & Advantages
- Simple and Robust Structure-Easy to operate and maintain, with reliable transmission devices and long-term stable operation.
- Multiple Classification Types-Available in High Weir (overflow particle size 0.83mm to 0.15mm) and Submerged (overflow particle size 0.15mm to 0.07mm) types for different classification particle size requirements.
- Double and Single Spiral Options-Provides options for single or double spiral configurations, with the double spiral offering greater processing capacity suitable for large-scale operations.
