The work of the vertical mixer is to rapidly rotate the screw to raise the raw materials from the bottom of the barrel to the top, then throw them away in an umbrella and return to the bottom, so that the raw materials can be rolled up and down in the barrel and stirred, and a large number of raw materials can be evenly mixed in a short time. It is suitable for mixing and stirring various plastic particles and masterbatches, and the effect of new and old materials and masterbatches is better. The contact part between the equipment and the material is made of stainless steel, which is easy to clean. No feeding equipment is needed. Feeding under the bottom and discharging under the bottom can greatly reduce the labor intensity. Mainly used for mixing raw materials, polypropylene plate lining or stainless steel plate is used in the plate, so it is not easy to stick. Wear-resistant, cycloidal pinwheel reducer has the characteristics of compact structure, easy operation, uniform mixing, convenient unloading and transportation. It is used in the production line of organic fertilizer equipment.
