The final thesis discusses the process of developing roller mill for pressing grains of wheat. It features the main purpose of processing feed, and various ways to do it. Based on the analysis of individual treatment method, we decided to develop a machine for processing wheat grain according to the method of compression by rolling. At the beginning of the development process, we set the requirements that we followed through the entire process. We have done the necessary calculations and on that basis designed a device for processing and compression of wheat intended for animal feed.
