The vibrating mixer mixes some different materials, but the mixing uniformity is poor and the mixing efficiency is too low.
It enhanced the collision between the grinding medium, which was effective for grinding brittle material particles especially.
Feng Weiming of Shandong studied the non-harmonic vibrating conveyor, and verified that the efficiency of material transport in a certain excitation frequency had the optimal value by computer simulation.

Summary We have performed first-principles calculation to investigate the adsorption of O2 on gallium doped graphene to analyze the suitability of using gallium doped graphene as toxic gas sensing materials in air.
This limits the practical application of gallium doped graphene based structures as efficient toxic-gas sensing materials in the presence of oxygen.
