The new compounder generation. Incredibly different.
The polymer industry’s innovation and earnings potential lies in the production of extremely high quality compounds. End products should be reinforced, scratch-resistant, flame-retardant, weather-resistant and at the same time resource-saving. This requires a compounder which easily and thoroughly mixes in significant amounts of additives. Meet COMPEO, the new state-of-the-art compounder delivering more diversity in its application, greater flexibility in process engineering, and increased value added in compound manufacturing.
COMPEO’s innovative operating principle
In the basic version with two inlet zones, polymers, additives and some of the fillers are fed through the first intake opening. The polymers are molten and mixed with the additives in the melting zone. In the second feed zone, further fillers are added via a side feeder and distributed homogeneously in the downstream mixing zone. Incredibly flexible. Incredibly different. Volatiles and entrapped air are removed in the degassing zone before transfer to the discharge unit. The processing length, type and number of feeding units, temperature, degassing and process geometries are defined according to the compounding application.
New screw geometries extend the process window
The new COMPEO series screw geometries ensure high throughputwith up to 20% lower RPM. Increasing the volume-related torque by 15% enables the configuration of longer mixing zones. That results in more stable process conditions without a higher energy input. The systematic free-form surface design of the screw flights ensures evenly intense shearing of the product and eliminates local overheating.
The configurable process zone of the COMPEO compounder opens up completely new process engineering possibilities through the application of mixing and kneading elements with two to six rows of flights. The combination of traditional three and four flight elements with newly developed mixing elements allow, for one thing, achieving goals which in the past conflicted with each other, such as high specific throughput with controllable energy input. For another, the COMPEO process window is considerably larger than those of previous models. Throughput can be varied in a ratio of 1:6, increasing both system flexibility and user-friendliness. The high throughput ratio is particularly advantageous for starting up, for small lots, and for in-line processes, where the downstream unit requires consistent product quality even with greatly varying throughput rates.
