The mixer with z-shaped working blades for high viscosity components

Abstract

The imperfection of the mixing technique affects the quality of products. The process of mixing the components is among the most energy-intensive, positively influencing the quality of finished products and shelf life. The mixer, having three chambers, through which pass two shafts, while the high speed shaft located in the first chamber, is installed inside the low-speed shaft. The design feature of a mixer is a z-shaped working blade, located on the fast shaft, which improves the process of mixing the components. On a high-speed shaft after the Z-shaped blades are two tape spirals of different diameter with opposite winding, providing a direction of flow of the mixture toward each other in a cross-counterflow. Working bodies (cone-shaped blades and band spirals) are three kinds of the movement of the mixture in the mixer: tangential, radial and axial flow. Mixer allows to optimize the mixing process of raw materials, different in grain-size composition and physical properties, due to the rational character of the movement of the mixture in each working chamber depending on the functional purpose of the product. In addition, expanding the scope of the mixer due to the achievement of the universalization of the mechanism of mixing taking into account characteristics of physical and mechanical properties of initial components. In addition, decreasing the duration of the technological cycle of obtaining ready mix, and hence reduce the specific energy consumption of the mixing process in achieving a better homogeneity of the finished product.
