Calculation of Combination Coefficient and Drag Coefficient for the Throwing Materials of Inertial Rotary Vibrating Screen

Abstract:

The structural characteristics and the working principle of inertial rotary vibrating screen are introduced in this paper. The inertial rotary vibrating screen is a kind of high efficient equipment for the screening classification of dry and wet fine materials. It has the features of simple and compact structure, convenient installation and disassembly, stable work operation, no sieve pore blocking, high screening efficiency, and the whole machine closure without polluting environment. The nonlinear vibration equations of inertial rotary vibrating screen are established, considering the nonlinear forces of materials. An approximate solution and the material combination coefficient and drag coefficient for the vibration equations are solved by equivalent linearization method of nonlinear theory. A calculation example is also given in this paper.
