Abstract: This shear mixer for polymeric material has two mateable bodies that, when pressed in mating condition together, form a reverse flow path for the movement of the material being mixed. The mixer has two mixing gaps, each defined by a primary wall surface on one body and an opposing wall surface on the other.

The mixing method involves not only increasing the length of a mixing gap as material is pushed through it for mixing, but also causing flow of material through one mixing gap to be in a direction opposite but parallel to the flow of material through the other mixing gap.

Abstract: The mass flow of the individual goods fed from a respective storage tank by a conveying apparatus is measured by a flowmeter. The mass flow is controlled via a controller. As long as the actual value of the flow masses of each separate component does not correspond to their respective rated value, all mass flows are returned via a switch-over valve and a return line back to the respective storage tank. When all actual values correspond to their rated values, the switch-over valves will switch such that the individual components are guided through the feed line to the mixing apparatus. The mixture produced in this mixing apparatus is once more analyzed by further detecting devices. If the analyzed actual values again do not correspond to the rated analyzed values, an immediate switching of the switch-over valves to the return bypass operation is again initiated.
