In the core processes of mineral processing and sand and gravel production, the spiral classifier remains an indispensable classification equipment. Relying on mature technology and stable performance, it has become a reliable choice for grinding circuits and ore washing & desliming operations.
Based on the principle of gravity sedimentation, the spiral classifier can accurately separate materials by particle size. Coarse grits are pushed out by the spiral, while fine particles flow out with the overflow. The classification precision is controllable, meeting the requirements of the full particle size range of 0.07-0.83mm. High weir type is suitable for coarse particle classification, submerged type specializes in fine particle separation, and single or double spiral structures can be selected as needed. It can be easily matched with ball mills and other equipment to form a closed-circuit cycle, avoiding over-grinding of materials, improving grinding efficiency while reducing energy consumption. It also lays a solid particle size foundation for subsequent flotation and gravity separation processes, helping to increase mineral recovery rates.
This equipment features a simple structure and convenient operation. The core components are made of wear-resistant materials, resulting in low operating failure rates and maintenance costs. It can adapt to the continuous operation conditions of mineral processing plants and sand and gravel plants. Whether for metal ore separation or non-metallic ore processing, it can stably deliver classification results, control stone powder loss, and ensure finished product quality. From intensive mine production to infrastructure sand and gravel processing, the spiral classifier, with its high adaptability and reliability, has become a practical choice for material classification in various fields, continuously empowering efficient production.
