separator

The developed mathematical model of a vibratory separator with sequential screen placement and spring suspension is nonlinear, unified, and parametric. It was derived based on the utilization of the second-order Lagrange equation and asymptotic methods of nonlinear mechanics. The model is intended for investigating the dynamics of the separator during its design and subsequent operation, particularly for selecting its optimal design parameters and determining the conditions of steady-state and transient operating modes.

In the article, a mathematical model of the oscillating motion of a vibrating separator is constructed. The methods of nonlinear mechanics and the calculation scheme of the vibration separator with an eccentric and a spring suspension, which is presented in the form of a flat mechanical system with four degrees of freedom, were used for its construction. The amplitude of oscillations of the vibration separator capacities in the vertical plane is greater than the amplitude of its oscillations in the horizontal plane.

A substantially new in design an experimental sample of complex equipment intended for crushing of various fragile and elastic materials, in particular plastics and obtaining powders of a different dispersion was built. The equipment consists of a shock-rotary crusher, a six-polar electromagnetic separator, two types of classifiers that allows to obtain the powders with a dispersity up to 0,05 mm applying raw materials of 5÷15 mm of diameter.
