From micronic particles to milimetric granules using granulation process
A powder is a material composed of fine solid particles. These particles can vary in size and shape and generally consists of a wide particle size distribution that is inherent to the production mode employed and leads to a non-uniform final product.
The finer the particles are, the more hazardous they are and their manipulation requires the use of fumehoods and adequate personal protection equipment such as FFP2/FFP3 protection masks. This hazard also impacts the transport procedures from the manufacturer to the final user. So, one can be interested in reducing the volume of fine particles in the product.
