| abstract |
Process and apparatus for the continuous production of elastomeric compositions by means of at least one extruder, wherein the minor ingredients are used in the form of subdivided products, said products including at least one of the minor ingredients dispersed in a thermoplastic binding agent. Such products are conveyed to a dosing device by means of a pneumatic conveying line, and thus can be accurately metered and continuously fed into the extruder. The thermoplastic binding agent guarantees to the subdivided product free-flowing properties and high dimensional regularity and stability, even upon intense compression and/or friction stresses, such as those occurring in a pneumatic conveying line. |
