A slurry dispensing system is disclosed. A peristaltic pump may direct a flow of slurry out of a horizontal mixer to a slurry dispenser. This slurry dispenser may be operated on a programmed manner by a controller to dispense slurry into a container. Both a bypass valve and a dispensing valve of the slurry dispenser may be opened/closed on a programmed basis by the controller to deliver slurry to a container, such as a glass column. Slurry may be intermittently directed into a metering chamber of the slurry dispenser, while the remainder of the slurry being directed into the slurry dispenser may be recirculated back to the horizontal mixer.

The present invention relates to a mixer with a drum that comprises a mantle, a bottom and a top and which rotates around an axis of rotation.
