ABSTRACT:
A fluidizing mixer works a mixture of materials, such as polyvinyl chloride (PVC) resin, together with plasticizers and liquid stabilizers and the batch is then discharged at the end of a work cycle of operation. The mixer employs an electrically energized driver which drives a working member, such as a high speed mixing blade, such that electrical energy is expended as work is being performed on the material. During each work cycle of operation the amount of expended electrical energy is sensed for purposes of providing a work signal having a value in accordance with the energy being expended. A work cycle is terminated when the amount of energy being expended to work the material decreases by a given amount.
