What is the difference between a kneader and a planetary mixer? How to choose mixing machinery?
Oct 12,2021 JCT
The difference between the vertical kneader and the double planetary mixer:
1. Blade form: The vertical kneader has two low-speed vertical blades to form the blade form, and the double planetary mixer blade has double-low-speed blade + high-speed stirring shaft + scraping wall.
Vacuum kneaders are mainly used in chemical production fields such as silica gel, glass glue base material, butyl glue, hot melt glue, etc., which are prone to bubbles. The vacuum kneader belongs to an important branch of the kneader series and has formed a mature industrial chain in China.
The working principle of the vacuum kneader is that a pair of cooperating and rotating blades Sigma (or Z-shaped) produces a strong shearing effect, so that the semi-dry state or rubber-like viscous plastic can make the material react quickly to obtain uniformity. The mixing and stirring mechanical device.
The vacuum kneader adopts electric heating, steam, oil heating, water cooling and other methods for temperature adjustment, and adopts hydraulic cylinder turning and uncovering. The discharging methods include hydraulic pressure, tilting cylinder dumping, ball valve discharging, screw extrusion and so on. The cylinder body and the parts in contact with the material are made of SUS304 stainless steel to ensure product quality.
Advantages:
1. High efficiency, its mixing principle determines its stronger mixing efficiency than ordinary mixers.
2. It has a wide range of applications. Research shows that the planetary mixer can be applied to most materials with a viscosity of 1 million pcs and a solid content of less than 90%. With a variety of mixers and other auxiliary devices, it can completely replace most ordinary mixers on the market.
Shortcoming:
1. The structure is complex. The planetary mixer usually achieves planetary motion through planetary gear transmission. The transmission box has a complex structure and is not easy to maintain. Usually accompanied by noise problems.
2. The price is high. Whether it is a transmission box or a paddle bucket, precision processing is required, and the price is much higher than that of ordinary mixers.
