In a device for preparing a plastic mixture comprising at least two containers with different components, especially epoxide and polyurethane resins as well as a curing agent, from which the plastic mixture is prepared, and lines transporting different components from the containers to a mixing device where the components are mixed into homogeneous plastic mixture, the lines transporting separately the components (A, B) taken from assigned containers (140, 160), where at least one of the components (A, B) is a plastic component, comprise rate-adjustable pumps (130, 150) generating flow of the components (A, B) assigned to respective transporting lines and flow meters (133, 153) measuring continuously volume of each flowing component (A, B), wherein indications of the flow meters (133, 153) are inputs of the control system (190) adjusting the volume of each component and/or volumetric ratios of said components delivered to the mixing device in which the components of predetermined proportions are mixed in order to achieve a substantially homogenous plastic mixture. |
