Course detail

Mechanical Processes

FSI-KMPAcad. year: 2018/2019

The course is concerned with the following topics: mechanical manipulation and storage of loose material. Calculation of geometrical and physical properties of loose material and the state of stress. Main dimension of apparatus and unit operations (crushing, milling, classification, mixing of particles, storage, granulation and transport of loose materials).

Learning outcomes of the course unit

Fundamental properties of loose materials. Some raw materials and products are in loose and granular form. Fundamental principles of machines used for working loose material. Acquired knowledge can be used for calculation of main dimensions of equipment used in such plants.
