The blendor comprises a horizontal rotation's container and rotatory vertical stirring vane etc. and during the shaping material stirring, the container turned left, and the blade turned right, because the effect against the current, the direction of motion is alternately between each granule of shaping material, and the chance of contact mutually increases, and the blendor is little to the extrusion force of material against the current, and calorific capacity is low, and stirring efficiency is high, and the compounding is comparatively even.

Polyvinyl chloride (collectively referred to as PVC) is the most widely used thermoplastic material in the world today, and is the first to be industrialized. Statistically, the global productivity of PVC materials has exceeded 3313 million tons in 2001, and the annual growth rate of current PVC capacity is still as high as 4%. The PVC plastic has the advantages of low cost, short construction period, corrosion resistance, good comprehensive performance and the like, and the intensive production technology and the close association with the chlor-alkali industry lead the PVC industry to have close relationship with various post industries such as automobile decoration, building membrane materials, petroleum industry, mechanical and electronic industry and the like. Therefore, the development of PVC industry is promoted, the technology of the industry can be better and more rapidly improved, and the rapid development of national economy is driven. Therefore, the development of the PVC industry is of great significance.

With the increase of the demand, the existing mixer can not meet the production requirement of the existing PVC particles. During production, PVC particles needing to be stirred cannot be directly used, and need to be washed and dried. The washing process and the drying process are usually carried out by two independent devices at the present stage, so that the investment cost of the devices at the early stage is increased, the workshop space is occupied, the procedures are increased during the later-stage production, and the production efficiency is reduced. Therefore, a PVC vertical mixer with dehumidification and drying functions is needed.
