Cement Kilns: Design features of rotary kilns
The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to …
Indirectly heated rotary kiln – for efficient thermal processing
An indirect rotary kiln that keeps sustainability in mind without substituting quality. With a strong demand for the mining industry to adopt a more sustainable method of producing high-quality products, the machinery used must be designed to accommodate this need, while still maintaining a high level of efficiency and productivity.
Carbon regeneration – the sustainable way
In the adsorption process, carbon activity and adsorption capacity are decreased through organic fouling contamination with fuel and lubricants from processing equipment, flotation reagents, grinding aids, viscosity modifiers, humic acids and plastics.. Organic fouling slows the gold and silver adsorption rate and decreases the metal loading capacity of the carbon.
