Cement worm conveyor
Fránek, Martin ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor project contains of a detail and design of a sloping cement worm conveyor. The project consists of technical specifications and drawing documentation. The technical specifications deal with basic design, calculations and stress analysis. The drawing documentation reflects the main assemble conveyor, a bill of material and welding assembly of the spiral worm.

Spiral conveyor
Ploc, Jakub ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
Spiral screw conveyors, as conveyors without a traction element, use the effects of rotating spiral for transport. To ensure correct operation during upward transport, a prerequisite for functionality is created in this work. Furthermore, the selection of a suitable material for which the dried sewage sludge was selected is made. In the following parts, the design calculation, and the choice of the conveyor construction for the specified dimensional and performance parameters are performed. Finally, a strength check of the functional parts such as gutter deflection is performed. Part of the thesis is also drawing documentation, which is based on the text part.

Worm conveyor
Kolčava, Jiří ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor thesis deals with the creation of the assumption of the functionality of the screw conveyor depending on the angle of inclination, the determination of the main dimensions and the design of the drive of the inclined screw conveyor with the maximum angle of inclination to transport the glass crumb. This assumption is described on the basis of the accelerations that act on the elementary particle of the transported material. Subsequently, the conveyor is compared with a spiral screw conveyor. The construction part contains drawing documentation according to the assignment.

Neutralization of acid solutions
Pavlík, Ondřej ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
The present thesis is concerned with neutralization of acid groundwater after the hydrochemical uranium mining in the area of Stráž pod Ralskem. In the thesis is briefly described progression of the hydrochemical uranium mining and follow-up negative impacts on the environment. There is described the technology involved in its disposal. This is followed by the design calculation of major apparatus technology associated with neutralization of acid solutions. Output of technology is determined by the mass balance. The results are the main dimensions of the apparatus, mechanical parts and electric power each device.

Crop flow improvements at the Power Flow header
Štelcl, Michael ; Červinka, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The master's thesis is focused on a design of optimal working speed of auger and belt transporter which are parts of Power Flow header for standard type of combine harvester. In the master's thesis author suggest a new simplified theory of crop flow inside the Power Flow header. The thesis contain the factors which can affect the crop flow and comparison between the Power Flow and competitor's header. The thesis also contain geometrical characteristics of crop for four types of cereal.
