Mathematical Model of a Flash Drying Process

The paper presents a basic model of the flash drying process, as it is applied in a number of industrial applications, and illustrates this by means of a particular application: the drying of subbituminous coal. Besides its economic importance, that application is representative of those where the product is combustible, so that the drying needs to be conducted in an inert atmosphere, which is ...

The production of fish meal and oil

3.1.8 Drying. The purpose of the drying process is to convert the wet and unstable mixture of presscake, decanter sludge and concentration into a dry and stable fish meal. In practice, this means drying to a moisture content below 12%, which generally may be considered low enough to check microbial activity.

Step-by-step Dredge Mining Process

 · Staurolite magnet tailings contain 25-30% zircon, 15-20% aluminum silicate minerals and about 50% quartz. The relatively high specific gravity of the zircon makes gravity separation from the lighter heavy minerals possible using spirals. The zircon spiral concentrate is dried and recleaned by a process patterned after the titanium mineral dry mill.
