Kneader: Versatile Mixing Equipment

Dispersion Kneader

A Kneader is a versatile mixing equipment used in industrial applications to achieve the desired characteristics of different products.

Details of Kneader

  • The machine comprises a motor, cover press, main body, mixing chamber and rotor mechanism, gearbox, air control system, tilting machine, heating/cooling system, rubber belt transmission and base, etc.
  • The kneader can be made into vacuum, pressure, atmospheric, Normal temperature, high temperature, low temperature, etc. 
  • The temperature adjustment method of a kneader can be the jacket, halfpipe, far-infrared tile, steam, hot water, heat transfer oil, electric heating, cooling water, chilled water, and other methods. 

Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic

It is a device that is designed and developed to handle a range of materials that are usually difficult to mix. The Kneader is instrumental in processing, mixing, and producing high-quality pastes, suspensions, and polymer compounds.

Kneading processes are used in many industries, including rubber, plastics, adhesives, pharmaceuticals, and food products. The vacuum kneader is one of the most popular types of kneaders, as it helps to minimize air bubbles and oxygen exposure in the mixing process.


A Kneader usually consists of two blades, known as the Z-Blade mixer, that rotate at different speeds in opposite directions. The blades are generally curved, which allows them to scrape the sides of the mixing chamber and prevents the material from sticking to the walls.

Another popular type of kneader is the Sigma mixer, which consists of two blades that rotate in opposite directions, but the blades are straight. The Sigma mixer is used in the preparation of adhesives, sealants, and other applications where high shear forces are required.


The Kneader is a crucial component in the processing of different materials in the industrial sector. It assists in the mixing of a range of products, including plastics, rubber, and foodstuffs, amongst others. When mixed in a Kneader, the materials are blended to produce a homogenous product with consistent properties that are ideal for further processing.

The vacuum kneader is a highly efficient machine that helps to eliminate any unwanted gases or air bubbles in the mixture. This makes it perfect for processing highly viscous materials, such as rubber or adhesive. Its design features a vacuum chamber in which an airtight seal is created to reduce the pressure within the kneading chamber. Furthermore, it is equipped with a temperature control system, which ensures the temperature within the kneading chamber is kept at the desired level to optimize the production process.

The Z blade mixer, also commonly known as the sigma-kneader, is specially designed to handle heavy and viscous mixtures. It consists of two Sigma-shaped blades that move in opposite directions to mix the materials. These blades trap and compress the materials between them before kneading and extruding them. The Z blade mixer is popular in the production of plastics and rubber compounds.

The sigma kneader, on the other hand, has a double-arm mixer design that provides high-level mixing and kneading action. The blades rotate at high speed and can be customized with heating or cooling jackets to regulate the temperature of the mixture. It is mostly used in industries where high quality and consistency are critical elements of the manufacturing process. Some of these industries include the pharmaceutical, food, and cosmetics industries.


The Kneader is a powerful and valuable tool that plays a significant role in the production of many products in the manufacturing industry. The device is available in various types and is selected based on the intended application. The Z-Blade mixer and the Sigma mixer are amongst the most popular kneaders, with the vacuum kneader being the preferred choice where air bubbles and oxygen exposure are significant concerns. Mixing ingredients in a Kneader provides a cost-efficient, accurate, and low-energy process for manufacturing high-quality products that meet the demands of today’s market.

In conclusion, kneading machines are essential in the manufacturing process. They ensure that different materials are homogenously mixed and kneaded to produce high-quality and consistent products. The vacuum kneader, the Z blade mixer, and the sigma kneader are just a few of the many types of kneaders available in the market. Companies should choose the appropriate type of kneader depending on the properties, viscosity, and end application of their products.
