Flash dryers find extensive application in a number of end use industries, mainly for drying moist powders, filter cakes
, slurry, granules and more.
The demand for these types of cement is being accelerated by uptake of alternative fuels derived from waste materials such as foundry sand, used oils, sewage sludge, solid recovered fuels, filter cakes
, animal meals and fly ash.
With the help of existing mathematical models, we have expressed the specific resistances of filter cakes
, which came into existence by filtration of the aforementioned suspensions.
The EnviroSystem operates without the use of chemicals to produce manageable, dry filter cakes
from process water and cement slurry.
The existing landfill site mostly deals with filter cakes
and sludges from industrial processes, contaminated soils from redevelopment of brownfield sites and other wastes like asbestos and ash from incineration.
Figure 5(a) shows that the filter cakes
, with NaCl of 30% density added into the mud system mixed with the fluid loss additive, are dense on their surfaces and distributed regularly in tight connection, narrowing the pores for less filtration loss.
The Bella Series 543 mixer/dryer/cooler offers an improved method for drying or cooling powders, granulates and filter cakes
. The Bella dryer can be used for drying, mixing, spraying, agglomerating and cooling in the same unit without additional equipment or costs.
Second, the compactness of filter cakes
