Abstract
A device for processing plastics material, comprising: a screw machine having at least one treatment element shaft for plasticizing the plastics material, stored in a housing, to form a polymer melt, wherein the screw machine has a plasticizing zone, a compounding zone, and an accumulation zone arranged between the plasticizing zone and the compounding zone, having at least one accumulation element which holds the polymer melt, at least one melt channel which bridges the accumulation zone and connects the plasticizing zone and the compounding zone to one another.

A device for processing plastics material, comprising:
- a screw machine having at least one treatment element shaft for plasticizing the plastics material, stored in a housing, to form a polymer melt, wherein the screw machine has a plasticizing zone, a compounding zone, and an accumulation zone arranged between the plasticizing zone and the compounding zone, having at least one accumulation element which holds the polymer melt, at least one melt channel which bridges the accumulation zone and connects the plasticizing zone and the compounding zone to one another, and
- at least one melt filter device for filtering the polymer melt which is arranged in the melt channel.
A method for processing plastics material, comprising the following steps:
- feeding the plastics material into a screw machine;
- plasticizing the plastics material by means of the screw machine to form a polymer melt;
- conducting at least a part of the polymer melt from the screw machine,
- filtering the discharged polymer melt by means of a melt filter device, and returning the filtered polymer melt into the screw machine;
- and
- compounding the polymer melt by means of the screw machine.
