ABSTRACT:
An apparatus for continuous distribution of at least one additive, such as a pigment or the like material, in a particulate master or base material, such as a granular plastics or the like material, comprising a stationary chamber that has a relatively small volume and includes a rotary distributor having one or more arms with cranked end portions for movement along a circular path in a substantially vertical plane that is normal to the axis of rotation of the distributor; a first inlet for feeding the particulate master into the chamber is arranged below the upper horizontal tangent line of the circular path while at least one second inlet for feeding additive into the chamber is provided above the said tangent line.
A process for operating the apparatus by controlling input and output rates so as not to exceed a maximum charge level substantially defined by the upper horizontal tangent of the circular path and to form an inclined upper surface of the processed charge within the chamber for overrolling movement of the particles of the master with concurrent interblending of the additive supplied onto the inclined upper charge surface.
The inventive apparatus is particularly suited for continuously interblending a minor amount of at least one additive and a major or predominant amount of a master or base material of the type used in plastics processing, notably for coloring or the like modification of a plastics material or composition prior to extrusion or another plastics shaping operation.
