Continuous improvement of Romanian products in terms of performance and quality and diversification to meet the recipients are the main factors ensuring the competitiveness of agricultural market. In this way, the most important national interest of Romania should develop a competitive economy through quality, able to cope with current trends of international trade. Our country should have in the development of all branches of the economy in line with EU requirements and standards. Among other things, this fact requires the alignment of all products – both industrials and consuming – in accordance with the community rules referring to quality, security and environment. To achieve this purpose all the equipments and installations that are used have to respect the essential conditions of health and security, imposed by the in force legislation, by integrating them in the stages of conception, fabrication and utilization. It is also necessary refurbishment of most capacity, equipping them with modern equipment, efficient, highly mechanization, automation and computerization. This article proposes a study on the way the installations of fodder kitchens are constructed and used,in order to remove the tehnical problems and to ameliorate the compound feed production process. In this way there are presented some aspects of technological process of making mixed fodders, emphasizing the grinding stage, and there are analyzed certain problems that can appear, following the ways of improving this activity by the use of some automatic systems.  The automatic installation for grinding cereals is meant to be used in factories of mixed fodders, especially in those where the final grist is transferred to the next step of processing by mechanic transport with elevators or snail-conveyors. All grain processors, including those who produce compound fodder, must constantly pursue the following objectives if they wish to maintain their position on the market: reduction of production costs of the finished product; maintenance of product quality according to customer standards or requirements; compliance of regulations in forms on environment safety and protection. Being given the requirements outlined above, a facility for grinding grain forage within a fodder kitchen or FNC must go through the following technological flux: grinding grain in a single step, with a hammer mill; aspiration of the hammer mill with a suction fan to limit warming grinded product and increasing the capacity of grinding; filtering the air before being discharged into the atmosphere; using  a bunker for collecting the grindingfrom the hammer mill and the fine flour retained by the filter. Milling plants can be used in mixed fodder factory can adapt to new or existing plants to increase productivity, improve operating conditions of the hammer mill and reducing the quantity of dust discharged into the atmosphere by limits. But these facilities may be used in any area where it is necessary grinding of cereals, such as breweries and malt, alcohol and yeast factories, etc.
