Q1:What is the core separation principle of the spiral chute separator?
It adopts gravity-centrifugal synergistic separation. Based on the differences in density and particle size of various minerals, it realizes precise separation of fine-grained minerals in the fluid-dynamically optimized trough. The whole process adopts pure physical separation without any chemical reagents, which is eco-friendly and pollution-free.
Q2:What particle sizes of minerals is the spiral chute separator mainly suitable for?
It is mainly used for the separation of refractory fine-grained minerals. It can accurately capture fine minerals such as -0.45 mm, 800 mesh (0.019 mm) and -0.038 mm, and is also suitable for the recovery of conventional fine-grained tailings, perfectly making up for the technical shortcomings of traditional equipment in fine-grained separation.
Q3:What models of spiral chutes are available, and how to select the right model?
Five series (F/H/M/L/X) with various specifications are available. The selection is mainly based on mineral properties, processing particle size and capacity requirements. For example, Model F13 is preferred for gold ore and tin ore; Model H8 is used for hematite concentration; Model M5 is designed for coal-fired desulfurization; and Model F13+L5 is suitable for coastal placer separation.
Q4:What are the core advantages of spiral chute separators compared with shaking tables and felt-lined chutes?
① Higher separation efficiency for fine-grained minerals, completely solving the problems of tailings loss and resource waste;
② Pure physical process requiring no reagents, reducing chemical costs and being more environmentally friendly;
③ Low energy consumption, easy operation and maintenance, and flexible combination for the whole process including roughing, cleaning and scavenging;
④ Strong tailings discarding capacity, with up to 83% of tailings removable in the roughing stage, greatly reducing subsequent processing load.
Q5:What minerals and application scenarios are suitable for spiral chute separators?
They are suitable for ferrous metals, non-ferrous metals, non-metallic minerals, coal-fired desulfurization and other scenarios, including gold ore, tin ore, hematite, vanadium-titanium ore, chromite, copper ore, cobalt ore, scheelite, quartz sand, coastal zircon-ilmenite placer, etc. At the same time, they can efficiently recover fine-grained tailings of various minerals to realize secondary resource utilization.
Q6:What is the processing capacity of spiral chutes, and can they be used for large-scale operations?
The capacity of a single unit varies with model, mineral and particle size (e.g., approx. 0.83 tph/start for gold ore separation, approx. 0.65 t/h/start for hematite concentration). Flexible combination of single or multiple units is supported, and processes such as one roughing & one scavenging, one roughing & one cleaning & one scavenging can be constructed, fully meeting the large-scale separation requirements of small, medium and large mines.
Q7:What mineral recovery rate can be achieved by spiral chute separators?
The separation recovery rates are excellent for different minerals, with key indicators:
① Recovery rate of fine-grained gold ore: 87.11%;
② Zirconium/titanium recovery rates of coastal zircon-ilmenite placer: both over 98%;
③ Cobalt ore roughing recovery rate: over 92%;
④ Scheelite tailings recovery rate is higher than traditional flotation process, and tailings recovery efficiency of tin ore, vanadium-titanium ore, etc. is also greatly improved.
Q8:Is the daily maintenance of spiral chute separators complicated? What is the service life?
The equipment has a simple structure with no complex wearing parts. Daily maintenance is easy, only requiring regular inspection of trough wear and removal of pulp impurities. The trough is treated with special wear-resistant and anti-corrosion technology, featuring long service life under normal use, and can meet the demand of 24-hour continuous operation in mines.
