Supervisor: doc. Ing. Jaroslav Jícha, CSc.  
Supervising institute: ÚPI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The course objective is to make students familiar with fundamental properties of solid particles, shape of particles, specific area, sphericity, porosity and stress analysis as well as classification and sizing of granular material,,crushing, grinding and milling of particles.
Agglomeration. Short distance transport. Mixing, dosing and storage of granular material. Fundamental principles of plant units and equipment.
Designing main dimension of equipment.
Learning outcomes and competences:
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.
Prerequisites:
Basic knowledge of mathematics and physics.
Course contents:
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).
Teaching methods and criteria:
