Internal mixer is a kind of high strength intermittent mixing equipment developed on the basis of open mill. Since the real Banbury type internal mixer appeared in 1916, the power of internal mixer has been gradually recognized. It has shown a series of characteristics superior to the open mixer in the rubber mixing process, such as: large mixing capacity, short time, high production efficiency; Better overcome the dust flying, reduce the loss of mixing agent, improve product quality and working environment; Safe and convenient operation, reducing labor intensity; It is beneficial to realize mechanical and automatic operation. Therefore, the appearance of internal mixer is an important achievement of rubber machinery, and it is still a typical important equipment for plastic refining and mixing, which needs continuous development and improvement
What are the differences between internal mixer and kneader, and what are the differences between their product applications?
Kneader is a device that makes semi dry or rubber like viscous plastic materials react quickly to obtain uniform mixing and stirring due to strong shearing action generated by a pair of matched and rotating blades (usually in Z-shape). It is an ideal equipment for mixing, kneading, crushing, dispersing and re polymerizing various high viscosity elastoplastic materials. It has the advantages of uniform mixing, no dead angle and high kneading efficiency. It is widely used in high viscosity sealant, silicone rubber, neutral acid glass glue, chewing gum, bubble gum, pulp, cellulose, and also in batteries, inks, pigments, dyes, medicine, resins, plastics, rubber Cosmetics and other industries.
What are the differences between internal mixer and kneader, and what are the differences between their product applications?
The kneader can be made into four types: ordinary type, pressure type, vacuum type and high temperature type. The temperature regulation method adopts jacket, steam, oil heating, water cooling and other methods. The hydraulic cylinder turnover and cover opening are adopted. Discharging methods include hydraulic pressure, cylinder turnover dumping, ball valve discharging, screw extrusion, etc. It can control and record the temperature, time, viscosity and other relevant data in production in real time through PLC. The cylinder block and the contact part between the blade and the material are made of stainless steel to ensure the product quality.
