Abstract
A melt filter, for the purification of plastic melts, particularly dispensed from extruders, comprises a housing () with a melt channel (), connecting a melt inlet () to a melt outlet (), with a sieve disc (), which may be rotated by a motorized ratchet drive provided in the melt channel (), comprising recesses separated by ridges in a circular track for housing exchangeable filter elements and the housing () has a filter element changing station (). The aim of the invention is that the above shall be designed such that large amounts of melt for filtering can be filtered in a cost-effective energy saving and space saving manner. The above is achieved by means of the housing comprising at least two melt inlets () connected to the melt outlet () by at least two melt channels () and in each melt channel () a sieve disc () driven on rotation by a motorized ratchet drive is provided and each sieve disc () is provided with a filter element exchange station ().
