This bachelor's thesis focuses on the constructions of waste disposers. It contains a description of creating a new structural design. It was created from a research. The research is about the types of machine constructions in this area. Bachelor's thesis is also about placement of these machines in the crushing lines. Bachelor's thesis also contains an overview of manufacturers and companies that deal with the constructions in the question. The design was constructed based on the DUC16 from the company Unikasset. regarding the waste crusher DUC16 from Unikasset. After carrying out the balance sheet and functional calculations, the waste crusher was constructed. The output of the work is an assembly drawing.

Wood chipper - reliability
Pešek, Josef ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The bachelor thesis deals with different types of wood chippers and their reliability. It includes individual machines from different manufacturers and their comparison. Based on the division of wood chippers, I designed my own 3D model, according to which a fully functional machine was made and thus the mentioned reliability of the model was verified. Part of the work is drawing documentation.

Mobile Machineries Used for Grinding of Aggregates and Recycled Materials from Building Waste
Hurník, Štěpán ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor´s thesis is the introduction to the problem of grinding natural materials and recycling building waste by mobile crushing machinery. The first part of work includes a detailed description of crushers themselves and differences between them. Next basic machine development is dealt with, as well as questions evoked by this topic. These questions are concerned with the mobility and problems of recycling. Further, there are current market offers for the preformance given. It deals with the parameters of the individual machines, on which their mutual comparison is given and displayed in graphs. The final part of the thesis consists of the general evaluation of machines for the above-mentioned purposes from different points of view: comparsion, market supply and a careful view into the possible future progress.

Design of mechanical, electrical construction and software equipment of autonomous cell "Ice crusher" for Industry 4.0 testbed.
Horák, Lukáš ; Benešl, Tomáš (referee) ; Pásek, Jan (advisor)
The goal of this bachelor thesis is design and construction of an autonomous cell on a production line with the purpose of being an „ice crusher“. The purpose of this cell is to be part of a Testbed. The cell will be controlled using a HMI touch panel and PLC 1200. Information about how much ice the cell should pour into a glass is stored in an NFC chip on the bottom of the glass. The first part of the thesis comprises of brief introduction to Industry 4.0 alongside with description of the default and current state of Industry 4.0 testbed. Another part describes mechanical and electrical design of the cell. Last part of the cell describes software of the cell alongside with description of testing and installing the cell to the testbed.

Wood chipper - efficiency
Šulák, Petr ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
The objective of this bachelor thesis is to design the wood chipper. In the theoretical part I am dealing with the mechanical properties of the processed material. Furthermore, I am mentioning individual types of chippers and crushers. In the practical part, the basic parameters of the machine are deduced from the research. These values are entering into the calculations needed to construct the components that the chipper is assembled with. The thesis includes production drawings and a 3D model made in Autodesk Inventor 2019.

Production of crusher on the plastic waste
Květoun, Jan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
This thesis is focused on designing and manufacturing a shredder for plastic waste 2H for small companies, households and blocks of flats. Thesis contains brief description of plastics, their properties and usage in praxis. It deals with excessive production of plastic, noncircular economy of waste and unsatisfactory processing of plastic waste. There are examples of collecting, sorting and recycling technologies and their application in praxis. It consists of current overview of shredders available on Czech and Slovak market and their comparison. Practical part of this thesis focuses on design itself, its components, parameters and economic issues of manufacturing. Annex contains 3D model of shredder assembly, bought components overview, assembly drawings and photo documentation of created shredder.

Cutting farm machine
Hon, Pavel ; Opl, Miroslav (referee) ; Holub, Michal (advisor)
This project is devided to three parts - theoretical overview of cutting farm components, design of cutting farm for specified production cell and the design of chip conveyor for specified cuting machine. Theoretical overview introduces common commercial used components of cutting farm, their properties and using possibilities in particular regarding their applicability at cutting farm design and chip conveyor design. In the second part there is proposal of design of cutting farm for production cell consist of six identical multi-function machinig centers. For produced amount of chips there is proposal of their processing from the begining at cuting proccess up to their leavig production hall as a briquetts in a containers. At last part of this project there is complete design proposal of chip conveyor for mentioned multi-function maching center. Design is built from a basic line diagram up to design of particular components including calculations and analysis.

Stroje a strojní linky pro zpracovní dřevního odpadu - štěpkovače
Vaněk, Martin
Thesis describes machines and mechanical lines for the processing of wood waste - chippers. The teoretical part reports about chippers and their ulitization. Thesis introduces basic division of chippers with presentation of basic types of crushing devices. Czech and foreign producers are presented with their produced types of machines. At the end of the teoretical part are described individually machines and machinal lines with complete work process. This process is used for felling and following disposal of wood mass in wood lands and in cities. In the practical part thesis compares desinged machine sets in field laboratory mensuration. Measured values were compared. Costs and economical aspects of the compared machine lines are quantified in the end.
