Description

technical field

[0001] The present invention relates to a device for feeding material to a container according to the preamble of claim 1 .

[0002] The present invention is particularly suitable for loading or filling containers and installations with materials in which materials are stored, handled or processed under overpressure or underpressure.

[0003] The best field of application is milling plants, where the raw material is supplied by means of conveying and feeding means for milling to a vertical mill, such as a pneumatic discharge roller mill, by means of air conveying. Background technique

[0004] In order to load the raw materials to be pulverized, such as pre-dried lignite or cement clinker and slag into vertical mills, it is known to use two or three hasp locks or a bucket wheel lock, which ensure that the or seals required for pneumatic discharge mills operating under negative pressure.

[0005] However, the disadvantage is that these material locks are cos...
