The FRP Spiral Seperator is a continuous gravity separation device designed for the classification and concentration of fine minerals. It is typically used for roughing or pre-concentration stages, providing an energy-efficient method to recover heavy minerals before downstream processing. By reducing the load on subsequent equipment, it improves overall process efficiency while maintaining stable and low-cost operation.
【Capacity】: 0.15-10 T/H
【Feeding Size】: 0.02-2 mm
【Application】: chromite, tin, tungsten, tantalum-niobium, gold, coal, monazite, rutile, zircon, and other minerals.
Used for concentrating iron ore, ilmenite, chromite, and other heavy minerals, especially in fine particle size ranges where traditional methods are less effective.
Used as a pre-concentration device to remove gangue minerals before flotation or other downstream processes, reducing processing load and improving efficiency.
Applied in placer gold processing and alluvial deposits to recover fine gold and associated heavy minerals in gravity circuits.
Suitable for recovering valuable minerals from tailings, improving overall resource utilization and reducing waste.
In gravity separation processes, fine particle recovery is often limited by insufficient sensitivity of conventional equipment and the high operating cost of mechanically driven systems. These challenges can result in lower recovery rates and unstable downstream performance.
The spiral seprator addresses this by utilizing the combined effects of gravity, centrifugal force, and slurry flow to gradually stratify and separate particles based on density. This process operates continuously without external power, making it inherently stable and energy-efficient.
Its core value lies in providing effective pre-concentration of heavy minerals while minimizing operating cost and system complexity. By reducing the load on downstream processes such as flotation or magnetic separation, the spiral chute improves overall plant efficiency and process stability.
