Abstract (en)
[origin: EP0530636A1] An apparatus for the mechanical treatment of powder has an apportioning vessel (13) having a closable discharge outlet (13b) which can be introduced into a process container (2). Assigned to this apportioning vessel (13) there is a first balance (8). Assigned to a receiving container (23) into which the process container (2) can be emptied there is a second balance (22). A safety device (31) is connected, by its signal input, to the first (8) and the second balance (22) as well as to a first detection device (19) for detecting the ready-to-weigh state of the first balance (8) and to a second detection device (18) for detecting the closed state of the discharge outlet (13b). The signal output of said safety device (31) is connected to a powder delivery device (12). The safety device (31) evaluates the powder weight measured by the first balance (18) if simultaneously the ready-to-weigh state of the first balance (8) and the closed discharge outlet (13b) are indicated. In addition, the safety device (31) sums the powder weights measured by the first balance (8) and delivered into the process container (2), and blocks the conveying device (12) if the sum of the powder weights conveyed from the apportioning vessel (13) into the process container (2) reaches a predetermined first limit value or if the powder weight measured by the second balance (22) in the receiving container (23) after emptying of the process container (2) differs from the sum of the powder weights conveyed into the process container (2) by a predetermined value or more. <IMAGE>
