Coal Slurry Washery

The slurry washery begins with coal fines mixed with water and reagents in a Conditioner to create a dense suspension. This is then transferred via a belt conveyor to the Flotation Cell Batteries, where air agitation and reagent emulsification cause hydrophobic coal particles to rise as froth while ash-rich particles sink.

Coal Slurry Washery

Feed Capacity: 10 Metric Tons per Hour
System Components:\

8 Flotation Cells (Two batteries of 4 cells each)
1 Conditioner for slurry densification
2 Emulsifier Tanks with stirrers for reagents (Polyelectrolyte & Diesel)
1 Rotary Vacuum Drum Filter (8 ft × 12 ft)
1 Magnetic Pulley for tramp iron removal (24" wide belt)
Multiple Pumps: Fresh water, tailing pond circulation, belt wash, and borewell supply
1 Feeding Belt Conveyor with gearbox
1 Vacuum Pump for filter operation

Use

This Coal Slurry Washery setup is designed for wet beneficiation of coal fines, using froth flotation for separation of clean coal from ash-forming impurities. It enables coal recovery from fines, improves slurry handling, and ensures better utilization of resources in coal processing plants.

Description

The froth product is skimmed, dewatered using the Rotary Vacuum Drum Filter, and discharged as clean, low-moisture coal. Wastewater is circulated back using tailing pond centrifugal pumps, while a magnetic pulley ensures removal of any tramp iron from the material flow. The fresh water and belt wash pumps ensure system cleanliness and stable operation.

Key Advantages

Full-cycle slurry beneficiation in a modular design
Optimized flotation efficiency using dual 4-cell battery configuration
Integrated reagent dosing for maximum yield
Low-moisture clean coal output via rotary vacuum filtration
Closed-loop water handling with centrifugal recirculation
Tramp iron removal via magnetic pulley ensures equipment protection
Customizable layout for expansion and integration into existing plants
