Portable pulverized coal classification intelligent sample preparation system

The invention relates to a universal machine. The universal machine is mainly a coal industry, can also be expanded to the fields of food, medicines and the like, and particularly relates to a portable pulverized coal classification intelligent sample preparation system which is integrated with a novel vibrating screen, a corresponding matched hopper and a sliding table device. Aiming at the shortage of a screening device special for sample preparation at present, the defects in the prior, the size of the screened particles is large, the size of the screened particles is large, and serious noise pollution can be caused art are overcome. A portable coal powder classification intelligent sample preparation system capable of efficiently and accurately screening pulverized coal and other material particles and integrated a novel linear vibrating screen, a matched sample collection device-hopper device and a sliding table device for conveying materials into a whole, the problems that the screening is insufficient,
