Method for conveying and dosing bulk material during processing, connecting or coating surfaces by vacuum suction radiations, involves generating suction flow for extracting and dosing bulk material with injection-dosing pipe

摘要

The method involves generating a suction flow for extracting and dosing the bulk material with an injection-dosing pipe (9). The injection-dosing pipe is immerged in an extraction area (7) of the bulk material. The lower pressure of the suction flow is adjusted by suction of an air flow (L-D) as transport air on a value. The air flow stands under atmospheric pressure or low pressure. An independent claim is also included for a device for executing a bulk material conveying and dosing method.
