shearing rubber. Mixing can be either by internal mixing or external/open mill mixing which have very different safety problems. Internal mixing (eg. Banbury or Intermix mixers) The compound ingredients are fed into an enclosed mixing chamber via a feed hopper and mixed by the shearing action of two winged rotors and the walls of the mixing ...
Silica is particularly difficult to disperse in many rubber compounds. Sometimes the proper use of some compounding additives may help in achieving a better dispersion (ref. 28). Since curatives are usually added late in a rubber mix to avoid excessive heat history, they sometimes do not receive sufficient work history for good dispersion.
Mixing mills. Mixing mills (also rolling mills) are used for the manufacture of rubber compounds. A rubber base material is mixed with several additives, such as fillers, softeners, processing aids and colourants here. The two rolls of the rolling mill rotate in the opposite direction. For the purpose of mixing, one roll runs faster than the ...
Mid-States Rubber produces all of its own compounds on a computer-controlled compounding and rubber mixing system. Making all rubber compounds in-house means we have superior control, higher quality, lower cost, and greater consistency. This is a benefit to our customers since we are able to rapidly respond to customer's requirements.
Continuous Mixing Technology is based upon the principle of two counter-rotating, non-intermeshing rotors and a large free volume mixing chamber. A single large feed port that allows for high filler loadings and irregularly sized materials. Specialized rotor geometry facilitates efficient levels of shear and excellent dispersive mixing.
Mixing rolls are needed for the production of rubber and plastic compounds (plastic blends). The uniform mixing of the material increases the homogeneity. The more wear-resistant the mixing rolls and the better the cooling capacity, the more economical the process. The TIR and cylindricity is …

Santec's Two Roll Mixing Mills are widely used for mixing and kneading raw rubber, synthetic rubber, thermoplastics or EVA with chemicals into even materials. The even materials can be fed to calender, hot presses or other processing machinery for manufacturing rubber or plastic products.
Normally banbury mixers are used for mixing rubber and plastics. There are two types of banbury mixers which are Farrel 270 having the capacity of 270 liters and Farrel 440 having the capacity of 370 liters. The best mixing combination is the mixing of 35KG of Natural Rubber + 50KG of Synthetic Rubber to get the best product.
The extruder accepts warm rubber strip from a 2- roll mill. The screw conveys the compound to the die and force through the die under pressure. The hot feed extruders remain the first economical choice for straining of rubber compounds and as a feeder machine for Rubber Calenders.
