SUB-A
Flotation machines
SUB-A Flotation machines Metso Mineral’s experience in coal flotation technology extends throughout some 200 installations worldwide. Extensive automation and mechanisation in mines, combined with the increasing importance of coal as fuel and chemical feedstock has resulted in an ever-increasing demand to maximise coal fines recovery by flotation.
Special features
The Metso Sub-A Flotation machine represents flotation cell design and process knowledge at its best.
• Special diffuser blade design gives optimum bubble formation and flotation results.
The high technical specification ensures long trouble free operation and is ideally suited to the stringent demands of operators who need to maximise the efficiency of their process plant.
• Simple and effective pin-drive system for fixing impeller to shaft gives total reliability and ease of maintenance.
The selectivity of the cell-to-cell configuration is valued by many coal preparation engineers worldwide. Metsoss Sub-A Flotation cells provide the answer in a complete range of machines designed to suit the exacting conditions of coal recovery from fine tailings. Residence times for rougher or cleaner stages are critically important; as is the bank length: Metso provides the range to meet exact requirements. Continuous product development over 35 years in coal, results in these special features and benefits of the Sub-A Flotation machines.
• Open flow impellers for high efficiency and lower power costs. • Cast polyurethane impellers and diffusers for excellent long term abrasion resistance. • Collectors/frothers of aliphatic alcohols or diesel (gas-oil) have no effect on polyurethane. • Fabricated steel and cast iron skeletons give rigidity to impeller and diffuser, while flexibility of polyurethane blades allows passage of occasional tramp oversize.
• Cast iron hood and polyurethane sleeve on lower part of shaft resist abrasion. • Ports in hood provide maximum recirculation conditions. • Froth paddles feature easily removable shaft sections on each cell, which eases maintenance. • Cell proportions give optimum pulp circulation and separation characteristics, which improves results. • Tank-work is designed to take anti-abrasion liners such as basalt tiles, glazed epoxy or abrasion resistant steel plates to suit specific requirements.
