Abstract: The paper deals with the regranulate impact on the mechanical properties of fundamental material. It focuses on the mechanical properties analysis of materials with different regranulate content. To determine the mechanical properties we chose the tension test, which is one of primary mechanical properties tests.

Abstract: Precise and reliable information on the machinability of a material before it enters the machining process is a necessity, and hypotheses must be tested through verification of actual methods. This article presents conclusions of machinability tests on a new austenitic stainless steels X2Cr12Ni12MoTiN and describes appropriate parameters for the cutting zone during the process of turning. The content of this article also focuses on the analysis of selected basic indicators of steel machinability: quality of the processed surface. The results of the article are conclusions for working theory and practice for turning of austenitic stainless steels. Based on the cutting tests, cutting speeds of 80 to 200 m/min, feed rate of 0.05 to 0.2 mm and solid carbide insert WNMG 080404-NF.

Abstract: The article describes the activities of spray dry, for which was designed a mathematical model of the drying. This model allows to identify and define the process throughout drying. The output of this model is the equation of balance. Production process of ceramic granulate was selected as subject for simulations. Simulation model is created in Matlab program – Simulink according to the equation for energy balance and parameter values from real kiln. Simulation monitors the dependency of mensural granulate moisture on absolute moisture of drying gas on the output.
