دليل معدات التعدين: What Equipment Should You Use for Flotation Conditioning and Slurry-Reagent Mixing? A Complete Guide to High-Efficiency Agitation Tanks

The GBJ-type high-efficiency agitation tank has an enlarged impeller diameter and increased linear velocity, enhancing its capacity to mix slurry and reagents. The impeller is designed as an umbrella-type, which strengthens the mixing ability of slurry and reagents and also improves circulation. The tank is equipped with a guide body, with the impeller located inside it, increasing the agitation capability so that slurry and reagents are introduced into it, further enhancing circulation. During operation, the umbrella-type impeller generates a downward force, accelerating the suction capacity of the slurry, further strengthening the circulation of slurry and reagents. A nozzle is installed at the lower part of the guide body, into which the slurry and reagents enter, further improving circulation. The thorough mixing and circulation of slurry and reagents ensures full reagent interaction on the mineral surface, which is beneficial for flotation. Why choose the GBJ-type high-efficiency agitation tank? First, strong agitation capacity: with an enlarged impeller diameter and increased linear velocity, slurry and reagents are mixed more thoroughly. Second, good circulation effect: the umbrella-type impeller combined with the guide body and nozzle creates downward pressure and suction capability, continually enhancing circulation. Third, favorable for flotation: thorough mixing and circulation of slurry and reagents ensures complete reagent coating on the mineral surface, improving flotation indices. Fourth, mature and reliable structure: it is a conventional core device for pre-flotation pulp preparation in concentration plants. Fifth, full range of models: effective volume 0.58-45m³, motor power 2.2-37kW, meeting the needs of concentration plants of different scales. The GBJ-type high-efficiency agitation tank is mainly used in pre-flotation pulp preparation, complete mixing of slurry and reagents, agitation processes in various concentration plants, material mixing in the chemical industry, slurry stirring in the building material industry, and other scenarios. The users who need high-efficiency agitation tanks include metal concentration plants, mining enterprises, EPC contractors for mining equipment, maintenance and replacement procurement teams of concentration plants, maintenance departments of chemical plants, equipment procurement departments of building material companies, equipment distributors and stockists, and overseas mining project purchasers. When should a high-efficiency agitation tank be selected or replaced? New concentration plants require pre-flotation pulp preparation equipment; old agitation tanks produce uneven mixing, high reagent consumption, or poor flotation indices and need replacement; concentration process modification requires improved mixing of slurry and reagents and increased flotation recovery; different slurry concentrations and properties require adjustable mixing and circulation capacity. Export projects require stirring tanks adapted to overseas voltage and efficient mineral processing conditions. How to choose an efficient stirring tank? Step one: confirm the effective volume; select 0.58-45m³ based on slurry processing capacity and stirring time. Step two: confirm impeller speed and diameter; choose according to slurry concentration and reagent characteristics, with impeller speed 153-530 r.p.m and impeller diameter 240-1000mm. Step three: confirm motor model and power; select 2.2-37 kW according to stirring intensity and slurry properties. Step four: confirm installation foundation; it must be installed on a solid concrete foundation with anchor bolt fixation. Step five: confirm slurry and reagent inlet and outlet pipeline connections, ensuring smooth circulation. Step six: confirm tank material; choose carbon steel or stainless steel according to medium corrosiveness. Step seven: confirm impeller and flow guide material; select high manganese steel, wear-resistant alloy, or rubber lining based on abrasiveness. Step eight: confirm environmental protection and automation configuration; dust removal systems and central control systems can be equipped.
