Device and method for separating materials with different degrees of flowability

Abstract

The invention relates to a device for separating materials with different degrees of flowability, comprising: a rotationally driven hollow drum (10) having a perforated casing surface (11), wiper means (18) for wiping away the pressed material on the hollow drum (10), a continuous press belt (14) which can be pressed from the outside onto the hollow drum (10) by wrapping around a part of the circumference of the hollow drum (10), and which forms a nip point (36) together with the hollow drum (10) for the pressed material, wherein the press belt (14) is mounted by means of at least one drive roller (16) and at least one bearing roller (17), and at least the drive roller (16) is designed such that it can be pressed in a controllably variable manner in a pressing position against the hollow drum (10), separated by the press belt (14), wherein the position of the drive roller (16) relative to the hollow drum (10) is adjustably set by means of a first positioning device (21) via a control device (22); and a first end stop element (23) designed for mechanical position limitation, with which at least one part (24) of the first positioning device (21) comes into blocking contact with a first counter support (31) of the first end stop element (23) in the pressing position of the drive roller (16), and wherein the first counter support (25) of the first end stop element (23) is designed such that its position can be adjusted by means of the control device (22). The invention also relates to a corresponding method.

Description

technical field [0001] The invention relates to an apparatus for separating materials having different degrees of fluidity. Furthermore, the invention relates to a method for setting up a device for separating materials having different degrees of fluidity and a method for operating such a device. Background technique [0002] Such devices and methods are used in various industrial fields. Basically, it is possible to separate materials that have different flow properties from each other. Such devices and methods are used, for example, in the processing of animal / fish carcasses to separate animal bones or fish bones from skin, meat and / or sinew parts. They are also used to separate the skin, stem, seeds or pit from the pulp of vegetables or fruits. Another field of application is the separation of composite packaging, in particular cartons for beverage packaging, for example consisting of cardboard boxes covered with plastic film and / or aluminum foil.
