Process of quality improvement in the company producing building materials

The aim of the study was to identify the problems and improve the production of cement in a ball mill in terms of technology and management associated with the use of known methods and techniques to improve quality. A detailed analysis helped to explain the process which affects the efficiency of grinding cement and which is the most common cause of disturbance and incompatibilities in the process of milling, how the production process is managed and controlled in order to obtain the required grain size, which is the main parameter influencing the quality of the manufactured product. To manage the change of the process there has been used a value stream map for analysis of the intermediate process of cement production, transport to the silos, bagging and selling. Based on the research some proposals of the process improvement have been designed that might have a chance of implementation and execution.
