Embodiment Construction

[0025] The first exemplary embodiment shown in FIGS. 1 to 5 includes a first extruder 1 and a second extruder 2 . The first extruder 1 is arranged above the second extruder 2 . The first extruder 1 is driven by a first electric motor 3 via a first coupling 4 and a first transmission 5 . The second extruder 2 is driven by a second electric motor 6 via a second coupling 7 and a second transmission 8 . The electric motors 3 and 6 are controlled by a control device 9 .

[0026] The first extruder 1 comprises a housing 11 provided with a heating system 10, in which are formed two first housing holes 12, 13 extending parallel to each other and joining each other in an approximately "8" shape. The two first screw shafts 14 , 15 , which are coupled to the first transmission 5 , are arranged in the two housing bores 12 , 13 . The screw shafts 14, 15 are driven in the same or opposite directions. The first extruder 1 comprises a downstream feed hopper 17 arranged in the conveying di...

Abstract

The invention relates to a plant for the preparation of materials, comprising a first screw device (1) and a second screw device (2), arranged downstream thereof. The screw devices (1, 2) are embodied such as to be displaceable out of an operating position, by means of a functioning housing (33) in a removal direction (35) essentially laterally to a flow direction (32).

Description

technical field [0001] The invention relates to a material processing plant according to the preamble of claim 1 . Background technique [0002] In particular, in plastics processing it is often well suited to provide two or more successive extruders, each extruder performing a separate processing step. For example, when the plastic material is used in powder form, the feeding and melting of the powder can be performed in the first extruder. Homogenization and pressure build-up will take place in the second downstream extruder. Sequential extruder arrangements of this type are known, for example, from EP1005411B1, US3261056 and DE2304088A. The known devices are distinguished by the fact that it is difficult to incorporate additional processing steps which have to be carried out between the two extruders. The term "material" is basically to be understood as a flowable material which can be processed in a screw-type extruder. Contents of the invention [0003] The object...
