Product Details

The main body consists of tank, impeller-stator device and froth scraping mechanism. The tank is welded with steel plate, inner wall lined with wear-resistant rubber; impeller is cast with wear-resistant cast iron, driven by asynchronous motor; froth scraping mechanism is reciprocating scraper. Single tank volume 0.3-50m³, processing capacity 0.1-150m³/h, suitable for small and medium-sized flotation systems.

Motor drives impeller to rotate at high speed, negative pressure is formed in the impeller to self-prime air and slurry; air is cut into fine bubbles by stator, impeller stirs to fully mix slurry, reagent and bubbles; target minerals attach to bubbles to form mineralized froth, reciprocating scraper scrapes froth as concentrate, and tailings are discharged from tank bottom.

Product Advantage

Compact structure: No independent aeration equipment needed, small floor space, easy installation;
Simple operation: One-key start-stop, no need to adjust aeration volume, low maintenance cost;
Energy-saving and economical: Single unit energy consumption 10%-15% lower than forced air type, suitable for small and medium-sized enterprises;
Good self-priming performance: Impeller self-primes sufficient air, stable mineralization effect;
Strong adaptability: Can process various easily floatable minerals such as gold, silver and copper.
