SSPE 5

3.1. General

The conveyor hopper is used for the automatic conveyance of freely flowing plas- tic granules, regrind and powder. The hopper can only function in connection with a single-station vacuum conveying system.

The conveyor hopper functions according to the principle of suction conveyance. A high-performance turbine provides for the vacuum that is required to convey the material into the separator.

In the separator the material is separated from air by several filter cartridges. Af- ter the conveying time is finished the turbine is switched off and the material emp- tied.

The automatic filter cleaning takes place by adjustable compressed-air shocks (pulse duration).

On the hopper, there is a separate on/off switch (A) and a function con- trolling device which indicates the fol- lowing operational modes:

(B): lamp on - hopper switched on at the on/off switch (A); lamp flashes - the hopper is conveying

(C): lamp flashes - error

(D): lamp is on - hopper signals lack of material
