The big bags, which are delivered at ground level, are brought to the big bag discharge stations using forklifts, positioned with hoisting gear and docked using special systems so they are dust tight. Precise feeding of the materials into the conveying line is achieved by using dosing screws with fine and coarse adjustments.

Bagged goods are fed into the closed system on the ground level via feeding hopper stations. The feeding hopper stations have an extraction system for dust-free filling. In order to prevent coarse contaminants from entering the pneumatic conveying systems, the feeding hoppers are fitted with appropriate preliminary screens.

Contamination Free Dosing

Dosing units are also used here for feeding into the conveying line; the units may be dosing screws or rotary valves. To ensure that there is no contamination in the production, the raw materials are conveyed to the conveying scale again via an inline cyclone screener with a metal separator; this prevents contaminants or metal objects from getting into the conveying scale.

The vacuum weighing system, comprises the conveying scale and underpressure generator, sucks the raw materials onto the conveying scale while simultaneously weighing the material. Once the batch is complete, it is discharged into the subsequent mixing process via outlet valves.

Achieving Absolute Precission

Micro quantities in powdered form, which are delivered in drums and boxes, are weighed to the exact gram at a separate operator-guided ManDos weighing station. They are then added directly into the mixer via a special feeding hopper that is monitored through barcodes. This ensures that micro quantities are also weighed, registered, and documented accurately.
