A mixing apparatus for mixing particles in a liquid and its use are disclosed. The mixing apparatus comprises a tank (1) having a bottom (2) and a substantially vertical side wall (3), an agitation means (4) comprising a rotation shaft (5) located vertically and centrally in the tank (1), and an impeller (6) arranged at a height above the bottom (2) at the end of the rotation shaft (5) and the impeller (6) being a downward pumping axial or mixed flow impeller. The bottom (2) is equipped with a corrugated formation (7) comprising alternate consecutive ridges (8) and valleys (9), the ridges (8) and valleys (9) extending radially in relation to a center of the bottom (2), whereby the valleys (9) concentrate and channel the mixing power near to the bottom (2) to direct the flow of the liquid and to increase the velocity of the flow near to the bottom (2). |
