Summary
The course is to introduce the theoretical basis for the processing of raw materials, namely the preparatory processes (crushing, grinding, sorting), the main processes that separate část productive and part waste (physical separation methods, physical-chemical and chemical processes) and ancillary processes (drainage, surface treatment, drying to the desired humidity).
