Abstract
A continuous mixer or kneader, particularly for explosive, potentially explosive, and other critical materials, wherein longitudinally split barrel sections are maintained closed by a mechanism which is actuated to instantly split the barrel sections under emergency conditions to permit the material inside to be treated to prevent or inhibit ignition of the material. The machine includes an extruding die and a cutter, for cutting extruded strands to lengths, which is coupled to the mixer shaft in the barrel, and in addition includes mechanism for interrupting the cutting of strands when the barrel sections are split.
Claims11
A continuous mixer for explosive material and the like comprising:
- frame support means;
- a mixing barrel thereon including a plurality of longitudinally split barrel sections forming an axially extending passage having an inlet and an outlet, at least one of said barrel sections being movable between a closed, radially inner barrel forming position and a radially outer, open position;
- an axially disposed mixing shaft mounted in said passage;
- means mounting said barrel and said shaft for relative movement to mix material supplied to said inlet while moving it from said inlet to said outlet;
- means for moving at least said one barrel section between said radially inner position and said radially outer position so that the material in said chamber will be exposed;
- means at said outlet for extruding said material in strands and cutting said extruded strands into lengths;
- and
- means responsive to said one section being moved to said open position for interrupting the cutting of said strands.
A continuous mixer for explosive material and the like comprising:
- frame support means;
- a mixing barrel thereon including a plurality of longitudinally split barrel sections forming an axially extending passage having an inlet and an outlet, at least one of said barrel sections being movable between a closed, radially inner barrel forming position and a radially outer, open position;
- an axially disposed mixing shaft mounted in said passage;
- die means at said outlet for extruding material in strands;
- means mounting said barrel and said shaft for relative movement to mix material supplied to said inlet while moving it from said inlet to said outlet;
- cutting means at said outlet for cutting the strands to lengths;
- and
- means for moving at least said one barrel section between said radially inner position and said radially outer position so that the material in said chamber will be exposed;
- and means coupling said mixer shaft and said cutting means for operation in timed relation.
A continuous mixer for processing material comprising:
- frame support means, a mixing barrel thereon including a plurality of longitudinally split barrel sections, forming an axially extending passage having an inlet and an outlet, at least one of said barrel sections being movable between a closed, radially inner barrel forming position, and a radially outer, open position;
- an axially disposed mixing shaft mounted in said passage;
- means mounting said barrel and said shaft for relative movement to mix material supplied to said inlet while moving it from said inlet to said outlet;
- means for moving at least said one barrel section between said radially inner position and said radially outer position so that the material in said chamber will be exposed;
- die means at said outlet for extruding said material in strand form;
- and cutter means at said die means, and operating conjunctively therewith, mounted for movement with said one barrel section responsively to said barrel section being moved to said open position, for interrupting the cutting of said strands.
