Aims

·Providing the students with complete overview of function, principle and application of machinery and equipment in production of building materials. Individual machines from rocks mining, transportation, treatment, homogenisation up to transportation of raw materials into the plant itself are described. The subject deals with all machines for raw material processing in the production of mortars, raw ceramics, light building materials, concrete goods. The stress is laid on automation and robotics application in production of building materials.

Specification of controlled education, way of implementation and compensation for absences
