Experience top-notch rubber compounding with Crowns Machinery’s Banbury Kneader. Engineered for precision and efficiency, it’s the key to high-quality rubber processing

Banbury Kneader For Sale

The Banbury Kneader is a professional multi-functional mixing machine for the rubber and plastic processing industry, named after an American inventor, Fernley H. Banbury, the recipient of the patent. The Banbury Kneader is commonly used in the production of a variety of rubber and plastic product moulding parts, such as tyres, seals, hoses, gaskets, etc. The machine can effectively achieve high quality, homogeneous mixing and dispersing of materials, and therefore plays an important role in the mixing and processing of rubber and plastic materials.

Principle of operation

One of the most important components of the Banbury Kneader is the mixing chamber made of heavy-duty material, which is cylindrical in shape and is equipped with a pair of spiralling rotors rotating in opposite directions, so that the material is efficiently mixed as it is forced to pass through the narrow gaps between the rotors.

The kneader is equipped with a cooling and heating system to precisely control the temperature of the mixing chamber and prevent the rubber compound from overheating. It is also equipped with sensors and control systems to monitor temperature, pressure and other parameters to ensure that the material achieves the desired dispersion.

After mixing, the final mixture is discharged from the mixing chamber at an inclination of 140 degrees.

Difference between Banbury and Dispersion

Although they are both kneaders, there are some key differences in design, operation and application between the Dispersion Kneader and the Banbury Kneader:

Mixing Principle

The Dispersion kneader is primarily used for the uniform dispersion and mixing of various additives, fillers and colours in rubber compounds.

The Banbury kneader, on the other hand, is a multi-purpose kneader that plasticises and homogenises rubber or plastic materials while thoroughly mixing and dispersing them with various additives.

Rotor design

While the Dispersion kneader uses a single Sigma rotor that rotates in a single direction, the Banbury kneader uses a pair of closely meshed rotors that rotate in opposite directions, making it suitable for stronger kneading and shearing requirements.

Mixing Time

Dispersion kneaders typically require longer mixing times to achieve uniform dispersion. Banbury kneaders, on the other hand, are generally more efficient and take less time to mix due to their intensive mixing and kneading action.

Heat generation and control

Dispersion kneaders generate heat primarily through the mechanical forces applied to the material during the mixing process. The Banbury kneader generates more heat through intense mixing and kneading. It has a more advanced temperature control system and better heating and cooling capabilities.

Applications

Dispersion kneaders are mainly used in industries where precise dispersion of additives and fillers is critical, such as tyres, seals, etc. The Banbury kneader is more versatile.

The Banbury kneader is more versatile and focuses more on achieving consistency in plasticisation and the resulting compounds. It is more commonly used in plastics and adhesives.
