CALCULATION OF THE EMBRYOP ROLLLING MODE IN THE TECHNOLOGY OF PELLET PRODUCTION BASED ON FORCED NUCLEARING

Abstract

The production of raw pellets on a plate pelletizer using the forced nucleation technology includes two main stages: the formation of embryos in a shape close to a cube and the creation of a pellet shell by pelletizing them in the working area of ​​the pelletizer. For pelletizing, it is necessary to organize a rolling mode, which for cubic embryos should be implemented on a pelletizer with certain operating parameters: the angle of inclination of the plate to the horizon and its rotation frequency. The stability of the rolling mode is ensured by the absence of embryo sliding on the charge skull (CS) during pelletizer operation. Therefore, along with the specified parameters, an additional factor can be used that affects the stability of the rolling mode and pelletizing of embryos, which can be the coefficient of friction of the embryos on the charge skull. This parameter can be influenced by changing the humidity and density of the pelletizer's skull charge.
