Abstract
Abstract The invention relates to a method and apparatus for the semicontinuous mixing of an explosive composition containing a premixed powder component and gelatine component, in which the components from the respective containers are blown out from nozzle-shaped outlet orifices as jets by means of pressure media controlled by weight impulses. The jets meet to cause a premixing in a predetermined ratio whereafter the composition resulting from the mixing of the jets is postmixed more thoroughly by kneading, is subdivided into lumps and is transported away.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A method for the semi-continuous mixing of an explosive composition containing a premixed powder component and a gelatine component, said method comprising: providing a predetermined weight of each of said premixed powder component and said gelatine component in separate containers, each of said containers having therein a nozzle-shaped outlet orifice; injecting a pressure medium into each of said containers in response to indications of the predetermined weight of each of said components, and thereby forcing each of said components in the form of a jet out of the respective container through the respective outlet orifice thereof; causing the jets of said components to impinge to thereby cause premixing of said components in a predetermined ratio; thereafter kneading said premixed components in a post mixing operation to form an explosive mass; subdividing said mass into lumps; and removing said lumps individually from the mixing area.
Claim 2
Independent Claim
144 words
A method for the semi-continuous mixing of an explosive composition containing a premixed powder component and a gelatine component, said method comprising: providing a predetermined weight of each of said premixed powder component and said gelatine component in separate containers, each of said containers having therein a nozzle-shaped outlet orifice; injecting a pressure medium into each of said containers in response to indications of the predetermined weight of each of said components, and thereby forcing each of said components in the form of a jet out of the respective container through the respective outlet orifice thereof; causing the jets of said components to impinge to thereby cause premixing of said components in a predetermined ratio; thereafter kneading said premixed components in a post mixing operation to form an explosive mass; subdividing said mass into lumps; and removing said lumps individually from the mixing area.
Claim 3
Dependent Claim
62 words
A method as claimed in claim 1, wherein there are provided two separate sets of containers for each of said components, and wherein said method further comprises alternating the use of each of said sets, whereby when one of said sets is being provided with said components, the other of said sets is injected with said pressure medium to cause said premixing.
Claim 4
Independent Claim
198 words
An apparatus for the semi-continuous mixing of an explosive composition containing a premixed powder component and a gelative component, said apparatus comprising: first and second sets Of containers; each of said sets of containers comprising a container for said premixed powder component and a container for said gelatine component; each of said containers of each of said sets having a nozzle-shaped outlet orifice therein; means to charge the respective containers of each of said sets respectively with predetermined weights of said premixed powder component and said gelatine component; means for injecting a pressure medium into said containers of said sets in response to indications of the predetermined weight of each of said components and for thereby forcing each of said components in the form of a jet out of the respective of said containers through the respective outlet orifice thereof; said outlet orifices of the containers of each of said sets being aligned to have said jets thereform impinge to cause premixing of said components in a predetermined ratio; means for postmixing said premixed components to thereby form an explosive mass; means for subdividing said mass into lumps; and means for removing said lumps from the mixing area.
Claim 5
Independent Claim
198 words
An apparatus for the semi-continuous mixing of an explosive composition containing a premixed powder component and a gelative component, said apparatus comprising: first and second sets Of containers; each of said sets of containers comprising a container for said premixed powder component and a container for said gelatine component; each of said containers of each of said sets having a nozzle-shaped outlet orifice therein; means to charge the respective containers of each of said sets respectively with predetermined weights of said premixed powder component and said gelatine component; means for injecting a pressure medium into said containers of said sets in response to indications of the predetermined weight of each of said components and for thereby forcing each of said components in the form of a jet out of the respective of said containers through the respective outlet orifice thereof; said outlet orifices of the containers of each of said sets being aligned to have said jets thereform impinge to cause premixing of said components in a predetermined ratio; means for postmixing said premixed components to thereby form an explosive mass; means for subdividing said mass into lumps; and means for removing said lumps from the mixing area.
Claim 6
Dependent Claim
28 words
An apparatus as claimed in claim 3, wherein said means for charging and said means for injecting are alternately applicable to each of said sets of said containers.
Claim 7
Dependent Claim
42 words
An apparatus as claimed in claim 3, wherein said means for postmixing comprises a screw-type mixer having an open section for mixing and a closed section for kneading, said mixer having at an end thereof adjacent said closed section a contracted outlet.
Claim 8
Dependent Claim
22 words
An apparatus as claimed in claim 3, wherein said means for removing comprises transport means for removing each of said lumps individually.
