Embodiment Construction

[0052] in press figure 1 and 2 In an embodiment, the device has a receiving container or cutting compressor 1 for the especially thermoplastic plastic material to be processed, which is fed from above by means of a conveying device not shown, such as a conveyor belt. In the receiving container 1. The conveyed plastic material can be pre-shredded and / or pre-dried.

[0053] The receiving container 1 is in the shape of a cylindrical pot with vertical side walls 2 and has a horizontal flat bottom 3 with a circular cross section. The receiving container 1 can be closed or open at the top. The shaft 4 passes through the base 3 while being mounted in a sealed manner and has a vertical axis 8 which coincides with the container axis. The shaft 4 is driven for rotational movement by a motor 5 with a transmission 6 arranged below the base 3 . In the container 1 , a rotor 7 and a support disk 9 arranged thereon are connected in a rotational connection to the shaft 4 . The rotor 7 co...

Abstract

The invention relates to a process and an apparatus for the treatment of a material in the form of fragments or particles which is moved and / or rotated, mixed, heated and, if appropriate, comminuted by at least one mixing element (12, 21) in a receiver or cutter-compactor (1), where, in the course of the process, undesired substances which impair the treatment of and / or further operations on the material are removed from the material by introducing a gas, in particular air or an inert gas, in a region below the level of the material located in the receiver (1) during its operation, or below the level of material of the mixing vortex which forms within the receiver (1), where the gas is forced to flow through at least a subregion of the material, and where the gas then saturated with, or with an increased concentration of, undesired substances is discharged from the receiver (1) in a region above the level of the material located in the receiver (1) during its operation or above the level of the material of the mixing vortex.

Description

[0001] This application is a divisional application of the Chinese patent application CN 200880005034.2 with the filing date of February 8, 2008, entitled "Method and device for processing materials". technical field [0002] The invention relates to a method for processing material and a corresponding device for processing material. Background technique [0003] A large number of plastics recycling applications suffer from problematic charging effects such as high residual humidity, large density fluctuations, too large a charge fraction, etc. The performance of the attached extruder or the economics of the process is thus negatively affected. The extruders are subjected to these charge effects, which lead to reduced and fluctuating discharge power, non-uniform melting power, reduced product quality, possibly increased wear and overall reduced productivity. [0004] Devices for use in cutting compressors with two mixing knives arranged one above the other are known from th...
