In today's era of increasingly scarce mineral resources and increasingly stringent environmental protection requirements, how to efficiently and environmentally extract valuable minerals from complex ores has become a common challenge facing the mining industry. The spiral chute, as a mature and highly regarded gravity concentration equipment, is bringing revolutionary solutions to the mineral sorting industry with its excellent performance and environmental advantages. What is a spiral chute? A spiral chute is a device that uses the differences in density, particle size, and shape of mineral particles to form a thin layer flow within an inclined spiral channel with the help of water flow and gravity, thereby achieving mineral sorting. It mainly consists of a feed device, a spiral chute body, a interception chute, a product collection hopper, and a support frame, with a simple structure, no moving parts, and extremely low maintenance costs. Working principle: A clever combination of gravity and water flow Mineral slurry is fed into the spiral chute body from the top of the feed device. During the process of flowing down the spiral channel, due to the inclined structure of the channel and the special structure of the spiral, the mineral particles in the slurry under the combined action of gravity, friction, water shear force, and centrifugal force exhibit differentiated motion. The heavy mineral particles with high density and large particle size move along the inner side and settle at the bottom of the water flow, while the light mineral particles with low density and small particle size are pushed to the outer side or discharged with the water flow. By installing an interception chute at the bottom of the channel, different densities of minerals can be effectively separated, resulting in concentrates, intermediate products, and tailings. Excellent advantages of the spiral chute: 1. High-efficiency sorting with meticulous precision: It has excellent sorting effects on fine and ultra-fine minerals (0.03-2mm), especially suitable for difficult-to-process fine minerals. 2. Green and environmentally friendly, no pollution: The entire sorting process does not require the addition of chemical reagents, relying entirely on physical gravity sorting, without secondary pollution such as wastewater, waste residue, and exhaust gas, meeting the environmental protection requirements of modern industry and promoting the green development of mines. 3. Low operating costs and significant benefits: With no moving parts design, it greatly reduces energy consumption and equipment wear, has low maintenance requirements, is easy to operate, and significantly reduces production costs and improves economic efficiency. 4. Simple structure and small footprint: The equipment has a compact structure, small footprint, and is easy to install and debug, allowing flexible layout according to on-site conditions. 5. Strong adaptability and wide application: It can process a variety of materials and has strong adaptability to variations in feed concentration and particle size, enabling stable and efficient operation. Wide application fields: With its unique advantages, the spiral chute plays a key role in many mineral sorting fields: Black metal minerals: Iron ore, chromite, titanium ore, etc. Non-ferrous metal minerals: Tungsten ore, tin ore, gold ore, tantalum-niobium ore, etc. Rare metal minerals: Zircon, monazite, rutile, etc. Non-metallic minerals: Coal sludge, quartz sand, etc. for fine sorting. Choosing a spiral chute is choosing a reliable, economical, and environmentally friendly mineral sorting solution. It not only helps you maximize the utilization value of mineral resources, but also promotes the sustainable development of mines towards a green future!
