The present invention relates to a method for dosing and mixing viscous substances accurately and at a desired proportion. The dosable substance can be prepared, e.g., by mixing a solid substance into a liquid in a mixing container or by means of some other mixing apparatus. The mixed substance is then pumped to be packed, or for use elsewhere. The invention is based thereon that the mixture prepared in the mixing container is by means of a constant volume pump (7) circulated in a circulation piping (21, 29) provided with a pressure difference valve (26) for setting the pressure of the piping (21, 29) and a mixture output connection (30, 28) is arranged in the piping (21, 29) before the pressure difference valve (26) in the mixture flow direction. |
