1.Experimental equipment The production capacity is not required to be high, mainly for experiment or experimental production at the initial stage of enterprise investment. 2.Production equipment The production capacity is required to be high, mainly because the enterprise invests in the production of products. This device has a high relative strength design and does not require high power. Cooperate with other production equipment, including batching, automatic feeding and automatic discharging, to manufacture a complete PVC mixing production line, with high production efficiency and relatively low investment. According to the production requirements, a set of production lines can produce one or two products without changing the product form for a long time. The equipment has realized the assembly line, replacing the technical requirements of selecting large equipment for large production. 3.Batch type equipment It is mainly used in some places with strict batch requirements for PVC mixers, such as dyes, food, etc. The same batch of products cannot have special requirements such as color and taste differences.
