Spiral Concentrators
Product Overview
Spiral concentrators are globally trusted equipment, widely applied in coal, gold, iron ore, mineral sands, platinum, and chrome processing plants. Serving as a core component of the beneficiation process, these concentrators specialize in separating ore and materials with particle sizes ranging from 38 to 2,000 microns—delivering reliable performance for diverse mineral processing needs.

Turn count: 3 to 12 turns, customized based on your process’s separation precision and material characteristics.
Core Advantages of Spiral Concentrators
Flexible particle size range: Spiral concentrators can beneficiate materials between 38 and 2,000 µm, with performance adjusted according to ore type.
High separation efficiency: The optimized design reduces the number of processing stages required for your plant, minimizing the overall equipment footprint and lowering investment costs.
Targeted grade control: Equipped with sliding or auxiliary splitters, enabling precise adjustment to achieve desired mineral grades and recovery rates.
Enhanced impurity removal: Features exclusive Auto Reject Channel® technology, which effectively removes unsuitable particles and improves final product quality.
Extended service life: Trough surfaces are sprayed with polyurethane (to customized thickness), significantly enhancing wear resistance and prolonging the spiral’s operational lifespan.
Pre-application validation: Specialized test work for spiral concentrators is available, simulating your actual flowsheet to ensure optimal performance before full-scale deployment.
New Spiral Concentrator Series
To address emerging industry needs, advanced spiral concentrator models have been launched:
Ultrafine chrome spiral (UX7): Engineered for efficient separation of ultrafine chrome particles.
Coarse (-3 mm) particle spiral (SC25): Designed to handle larger particle sizes (up to -3 mm) with high separation accuracy.
Lowcut spiral (1.49) for coal application (SX10): Tailored for coal processing, delivering precise low-cut separation to meet coal quality standards.
Large diameter cleaner and recleaner stage spiral (SC21/5 LD): Developed for cleaner and recleaner stages, featuring a large diameter for enhanced separation efficiency in fine mineral recovery.
