Spiral chute: a smart choice for gravity mining, opening a new chapter of high efficiency and energy saving

#Industry ·2026-02-23

In the field of mineral processing, how to achieve efficient, energy-saving, and environmentally friendly mineral separation has always been the core goal pursued by the industry. The spiral chute, developed in response to this demand, has become an indispensable tool for modern gravity mineral processing with its unique advantages. 【What is a spiral chute?】 A spiral chute is a gravity mineral processing equipment that uses the combined effects of gravity, friction, water shear force, and the density and size differences of mineral particles to automatically stratify and separate different minerals as the mineral slurry flows on the surface of the spiral chute. It requires no external power, has a simple structure, and is easy to maintain, making it widely used in the sorting of various black, non-ferrous, rare, and non-metallic minerals. 【Why choose a spiral chute? Analysis of its core advantages】 1. High efficiency and accuracy with high recovery rates: The spiral chute can conduct fine sorting based on the slight differences in mineral density, effectively improving the recovery rate and enrichment ratio of target minerals. Its unique spiral chute design ensures stable mineral slurry stratification and significant separation effects, bringing tangible benefits to your mineral processing production. 2. Energy-saving and environmentally friendly with zero energy consumption: This is one of the most notable advantages of the spiral chute. It relies entirely on the gravity of the mineral slurry for sorting, without any external power, greatly saving energy consumption. At the same time, the entire separation process does not involve chemical reagents, avoiding secondary pollution and fully meeting the environmental protection concept of modern green mine construction. 3. Simple structure and easy maintenance: The equipment itself has no moving parts, fundamentally eliminating the occurrence of mechanical failures. This means lower failure rates, less daily maintenance work, and longer service life. It is simple to operate and easy to master, greatly reducing labor and maintenance costs. 4. Wide applicability and flexibility: The spiral chute has strong adaptability to changes in feed particle size, concentration, and grade, and can process a variety of non-ferrous and black metals, rare metals, and non-metallic minerals, such as gold, tungsten, tin, tantalum, niobium, iron, zircon, titanium iron ore, as well as coal, quartz sand, etc. Whether it is rough sorting, fine sorting, or sweeping sorting, it can provide excellent sorting results. 5. Low investment cost and short return period: Compared with other complex mineral processing equipment, the initial investment cost of the spiral chute is relatively low. Combined with its extremely low operating costs and high sorting efficiency, it can help enterprises quickly recover their investments and achieve higher economic benefits. 6. Small footprint and easy installation: It has a compact structure and small footprint, especially suitable for mines with limited site space. Its modular design makes it easy to install and commission, allowing it to quickly enter production. 【Application fields】 The spiral chute is widely used in the sorting of various black and non-ferrous metal minerals, such as gold, tungsten, tin, tantalum, niobium, iron, zircon, titanium iron ore, as well as non-metallic minerals such as coal and quartz sand for purification operations. Choosing a spiral chute is choosing a path towards efficient, energy-saving, and environmentally friendly mineral processing. Let your mineral processing process become smarter, more economical, and more sustainable!
