Belt conveyor for brick rubble
Roušavý, Filip ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor's thesis deals with the design of a belt conveyor for transporting brick rubble. The main objective of the thesis is to create an efficient conveyor system that meets the specific requirements of the brick industry. The work includes the classification of belt conveyors, analysis of structural elements, and selection of suitable components. Furthermore, detailed calculations are performed concerning the supporting stations, required motor power, and belt dimensions. The thesis also provides an overview of major belt conveyor manufacturers and describes various types of tensioning and cleaning devices. The result is a design of a belt conveyor that ensures reliable and efficient transportation of brick rubble.

Chemical Additives Effect on the Properties of Ceramic Mass.
Sarvaš, Ondřej ; Sokolář, Radomír (referee) ; Nevřivová, Lenka (advisor)
The bachelor’s thesis focuses on chemical additives used in the ceramic industry. There are described commonly used additives mainly in the fields of fine ceramic and special ceramic, as well as less utilized additives. The experimental part focuses on the influence of the additive BioKeram made by Borregaard for ceramic mass in the brick industry used for hollow clay blocks. A special focus is on the effect on rheological properties of the ceramic mass and a minor focus is on physical and mechanical properties of burned ceramic body.

Diagnostic Methods Suitable for Monitoring of Drying Process of Brick Product
Sarvaš, Ondřej ; Sokolář, Radomír (referee) ; Nevřivová, Lenka (advisor)
This work deals with the study of diagnostic methods suitable for monitoring of the drying process of brick raw materials. Based on the extensive literature search, several parameters are selected, which are appropriate to monitoring during drying. In addition, a methodology for measuring these selected parameters is proposed. In the experimental part, the use of all described methods is gradually verified on the brick raw material with and without shortening additive (also known as grog). Was carried out: measurement of the surface temperature in the climatic chamber, determination of humidity distribution in the sample, determination of moisture diffusivity, determination of tensile strength, determination of ultrasonic wave velocity and determination of dynamic E-modulus of elasticity. Results of experiments and the gained experiences show, that at least two of the above-mentioned monitoring methods are very appropriate and beneficial – determination of moisture diffusivity and determination of tensile strength. In the work was described in detail the procedure of determination of moisture diffusivity of material. The dependence of moisture diffusivity on the moisture content of the dried material, has been described. Also, differences between raw material with grog and without grog has been described. As part of the practical verification of the experiment designed to determine the tensile strength at different humidity levels of test samples. A new shape of the test specimens and a new device were designed to allow them to be attached to a hydraulic press. The results of this work show that the tensile strength of the ceramic green bodies is primarily dependent on the moisture content of the material. The type of raw material almost does not affect the tensile strength.

Productivity of work at brick industry
Popelář, Petr ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
Description of the technological process of production and overview of materials applied in the brick-making industry, which are used for the manufacture of fired bricks.The introduction of ground straw as a new material for brick making, which should replace the currently processed sawdust, mainly due to the high price of timber.The result is an overall evaluation of useful characteristics, demands on processing these two materials and their mutual comparison from a technological and economic point of view.
