Worm conveyor of fine aggregate
Vosika, Jan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The main aim of the thesis was to design a horizontal worm-conveyor for the transport of fine aggregate of maximum aggregate gradation of 45 mm, both in terms of construction and strength. The design section of the thesis deals with the problem of an appropriate conveyor driving gear and skidding clutch between the gear and the transport unit according to the amount of transported aggregate. In the computation section, strength check of the drive system is addressed, namely the shaft check, its coupling with the other parts, and the bearing housing. In the last section, the structural design is addressed with respect to safety of operation and ease of maintenance.

Design of facility for egg-shells transportation
Hruška, Kryštof ; Naď, Martin (referee) ; Pernica, Marek (advisor)
Egg shells are a very suitable basic raw material for the production of mineral dietary supplements. The thesis deals with one of the processes in their production, the transportation of the commodity after flush into a clean room. The thesis proposes possible solutions, which are described in the research part, on the basis of which a screw conveyor is chosen as a suitable solution and a design solution is proposed. Based on the calculations, the individual parts of the conveyor are selected and designed. The entire device is modeled in SolidWorks and the drawing documentation contains the overall drawing of the assembly.

Determination of stability of fuel feeding into boiler
Skalický, Michal ; Chýlek, Radomír (referee) ; Lisý, Martin (advisor)
This bachelor thesis deals with the determination of stability of fuel feeding into boiler. The principle of the screw conveyor is described at the beginning of the thesis. It is followed by a description of the individual parts of the worm. The second part of the research deals with the properties of the materials transported. The second half of the bachelor thesis is practical. In this section there are experimentally measured values of flow of sawdust and wood chips. At the end, the measured values are compared and evaluated.

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.

Optimization of method for evaluation ETICS dirtiness
Gabriel, Jindřich ; Žák,, Antonín (referee) ; Žižková, Nikol (advisor)
This diploma thesis deals with the issue of adhesion of pollution to the final surface treatments of the ETICS system. The theoretical part deals with important factors and processes that affect the degree of adhesion of pollution. The practical part of the diploma thesis follows the diploma thesis of Ing. Jakub Krejčík. Optimization of test methods for simulation of artificial pollution on tested samples was proposed. These samples were then evaluated in the laboratory and also compared with plasters that were exposed to real pollution from the natural environment.

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.
