ENERGY RECOVERY IN GRANSHOT®-PROCESS Granulation

In the process liquid metal is splintered granulated into small drops granules in sizes from 1 to 50 mm in diameter. The drops are rapidly cooled in a water bath where all the heat energy from the liquid metal is transferred into the water. The granulation is often performed with great metal flows. Normally 1-4 tonnes of metal is

Wet Granulation Process : Pharmaceutical Guidelines

Wet granulation involves the massing of a mix of dry primary powder particles using a granulating fluid.The fluid contains a solvent which can be removed by drying, and should be non-toxic.Typical solvents include water, ethanol and isopropanol and methylene chloride either alone or in combination. The granulation liquid may be used alone or, more usually, as a solvent containing a dissolved

Granulation Wikipedia

Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material.It is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use.

Wound healing Wikipedia

Wound healing is classically divided into hemostasis, inflammation, proliferation, and remodeling.Although a useful construct, this model employs considerable overlapping among individual phases. A complementary model has recently been described where the many elements of wound healing are more clearly delineated. The importance of this new model becomes more apparent
