FIELD: process engineering.SUBSTANCE: set of inventions relates to control over batching and mixing system. System comprises first pump to feed first component to mixer and second pump to feed second component to mixer. Piston stroke of every pump can be reversed from direction of suction and displacement to component displacement direction and visa versa. Motion detector connected with controller is connected with every pump. Said controller is programmed to initiation of pump stroke direction reversing after determination of that component volume that stays in the pump insufficient for setting of preset metered ratio. Said controller is programmed to continuous feed of first component to the mixer and intermittent feed of second component to the mixer to conduct cycles of batched feed of second component to the mixer.EFFECT: improved batching and mixing performances, higher homogeneity of the mix.9 cl, 4 dwg |
