The apparatus of the present invention comprises a plurality of flexible impact elements for controlling the buildup of solids in a mixer, submerged flight conveyor, unloader or similar device. The device for use with the impact elements has at least one shaft and a plurality of rotating elements which rotate around a drive sprocket or extend radially from a shaft for moving ash or similar particulate solids. The flexible impact elements communicate with the device so as to limit or control the buildup of solids on the rotating elements, thus enabling a more efficient throughput of materials by the device.

A continuous paste mixer comprising a mixing apparatus secured to a frame is described herein. The mixing apparatus includes one or more mixer assemblies configured to extend and stack with respect to the frame, the one or more mixer assemblies to mix various ingredients (thixotropic and/or non-Newtonian) continuously and uniformly without risking uncontrolled exothermic reactions. The continuous paste mixer comprises a support member operatively connected to the mixing apparatus, and a controller configured to automatically control movement and operation of the high-shear mixer during mixing according to one or more mixing profiles.

Disclosed herein are methods for preparing an elastomer composite including charging a mixing chamber with at least a solid elastomer and a filler through a ram enclosure and mixing the solid elastomer and the filler in the mixing chamber. The mixing includes moving a ram through a ram space towards the mixing chamber to push the elastomer and the filler in the ram enclosure downwards into the mixing chamber. The mixing further includes directing a flow of gas through the ram space from a vent inlet to a vent outlet disposed in the ram enclosure, the flow of gas passing through the ram space and entraining at least a portion of a vapor resulting from the mixing, and discharging the elastomer composite from the mixing chamber.
