Dynamics Analysis in Materials on Solid Wastes Separation Sieve and Selection and Calculation of Kinetic Parameters

Abstract

The paper presents the structural characteristics of solid wastes separation sieve. Pieces of plastic film and sandstones with different friction factors and elasticity coefficients are chosen as the research objects. The motion and the separation mechanism of materials in the sorting process are studied. According to the motion analysis on pieces of plastic film and sandstones on solid wastes separation sieve, it can be concluded that the materials with different friction factors and elasticity coefficients can all be sorted by solid wastes separation sieve. The more difference they have in friction factors and elasticity coefficients, the better separation performance can be achieved. The selection and calculation on the kinetic parameters of solid wastes separation sieve is carried out, which provides the theory evidence for the design of new friction sorting equipment and opens up new prospects for the application of solid wastes separation sieve.

Study on the Dynamical Parameters of Inertial-Type Counter Flow Screen

“…Therefore, it is very meaningful to develop energy-saving and environmental protection equipment with China's actual conditions, low investment, easy operation, good performance and low energy consumption [1][2][3][4][5] . Inertial-type counter flow screen originated from China is a kind of sorting equipment to separate solid wastes by friction [6][7][8][9][10] . In this paper, the structure of inertial-type counter flow screen is introduced and the selection and calculation on its dynamical parameters is carried out.…”
