LINATEX Flat-Bottomed Classifiers
|
The Linatex® flat bottom classifier is a well proven performer for the hydraulic classification of particles by size or density. The classifier reliably extracts light or small particles from slurry at high efficiency, whilst displacing a minimum of heavy or coarse particles to the overflow.
Benefits
• Extremely efficient washing of soluble or colloidal species from granular particles by virtue of counter-current plug flow washing
• High sharpness with little misplaced material via direct bed level measurement
• Multiple discharge valves yield an even bed drawdown without valve blockages or channelling
• Multiple water injection nozzles result in uniform water distribution even at minimal flow rates
• No moving parts are exposed to process slurry, meaning little maintenance is required and a long operating life is achievable
• Low headroom design results in low capital costs, lower installation and maintenance costs and easier inspection
• Unlike cyclones, there is Zero bypass, ie no misplaced fines in the underflow
Applications
• Coal/ash separations by density
• Silica/heavy mineral separation by density
• Removal of deleterious material from sand including lignite, coal, wood, plastic/paper, clay/silt and mica
• An alternative to cycloning
○ where fines must not be present in the underflow
○ for removing large amounts of clays and slimes with low water additions for sharp classification in milling circuits
○ at cut sizes coarser than achievable by cyclones, typically between 100 and 1000 microns
