Abstract
A method for the production of slurries which are uniform in density and consistency. In particular, a method for preparing zinc anode slurries employed in producing anodes for alkaline batteries. The method comprises a bag slurry forming process, using a drum mixer, involving mixing dry anode components within a sealed, inplated, gas-tight, liquid impervious, flexible, collapsible bag; and, then adding a wet component to the bag, collapsing said bag, and tumbling-kneading the components to form a blended slurry.
Claims13
A method of forming a slurry of selected dry and wet component comprising:
- introducing selected dry slurry components into a flexible, collapsible bag;
- inflating and sealing said bag to confine said components therein;
- agitating the sealed bag within a mixing device,
- so as to blend the confined components;
- opening said bag and introducing a wet slurry component into said bag;
- collapsing said bag and resealing the bag to confine the wet and dry components therein;
- and,
- operating the mixing device to knead and blend the confined components into a slurry composition.
A method of forming a slurry of select dry and wet components comprising:
- introducing the dry and wet components into a flexible, collapsible bag;
- collapsing said bag and sealing the bag to confine the components therein;
- placing the collapsed bag within a mixing device;
- and,
- activating said mixing device to agitate said bag, so as to knead and blend the confined components into a slurry composition.
A method of forming a slurry in a rotating drum mixer comprising:
- introducing dry slurry components into a flexible, collapsible bag;
- placing said bag within a rotatable drum of the drum mixer;
- inflating said bag and sealing the bag to confine the components therein;
- rotating the drum to mix the dry components;
- opening said bag and introducing a wet slurry component into said bag;
- collapsing said bag and sealing the bag to confine the wet and dry components therein;
- and,
- rotating the drum to agitate and tumble said bag, so as to knead and blend the confined components into a slurry composition.
