The material conveying system is a professional auxiliary system, which needs to consider various factors such as power source selection, accurate measurement, closed conveying, continuity, insulation requirements, safety protection means, floor space and noise according to different material characteristics and working conditions. The effect of evaporative crystallization is closely related to the stable feeding quantity. Accurate control of feeding time, feeding speed and feeding quantity need to be scientifically targeted at the characteristics of materials, such as power source, material viscosity, the state of materials under different temperatures and pressures, intermittent feeding or continuous feeding, whether it is flammable and explosive, and other factors. For this purpose, tuochi can design according to different working conditions, provide accurate measurement, automatic control, accurate feeding and other means to provide a safe and reliable feeding system;
