device for gravimetric dosing and mixing of encourage free flowing material with other free flowing solid or liquid or teigförmigen materials
An apparatus for feeding, weigh proportioning and mixing a first flowable material with other likewise flowable or liquid or paste-like material, characterised by hopper equipment containing one or more separate chambers for separately storing said first flowable material, a stabilizing zone for said first flowable material in each of said hopper chambers, a first gating means at the bottom of each of said stabilizing zones, at least one first weighing means comprising a first weigh hopper, a first discharging device and a motion transmitting means, one or more storage hoppers for said other flowable or liquid or paste-like material, each associated with a second gating means, a second weighing device comprising a second weigh hopper, a closure fitted to said second weigh hopper and a second motion transmitting means, a second discharging device and a mixer, the arrangement being such that at least part of the charging opening of said first weigh hopper is in the direction of fall below its associated first gating means, that at least part of the charging opening of said second weigh hopper is in the direction of fall below the discharging means of the associated first weigh hopper and that the second discharging means is in the direction of fall below said closure of the second weigh hopper and provides communication in said direction of fall with said mixer. A method of operating the apparatus is also described.
