9. Cyclones • A cyclone is a conical vessel in which coal along with finely ground magnetite is pumped tangentially to a tapered inlet and short cylindrical section at a predetermined flow rate and pressure followed by a conical section where the separation takes place. • The higher specific gravity fractions being subject to greater centrifugal forces pull away from the central core and ...

Granulation techniques and technologies: recent progresses

The type of process selection requires thorough knowledge of physicochemical properties of the drug, excipients, required flow and release properties, etc. Granulation technologies like roller compaction, spray drying, supercritical fluid, low/high shear mixing, fluid bed granulation, extrusion/spheronization, etc. have been successful for many decades in the preparation of various ...

Coal Types, Uses and Formation Vedantu

Coal is a sedimentary rock that is blackish or brownishblack in colour and is developed from start rock also referred to as coal seams. This is assumed to have developed from the residue of the algae plants. Coal is composed of a maximum amount of carbon with other organic elements chiefly hydrogen followed by sulphur, oxygen, and nitrogen.
