The present invention relates to a mixing device (), especially for mixing solids in a mixing vessel (), comprising a stirring element () having at least two helical stirrer blades () connected to a motor-driven shaft (), wherein the stirrer blades () have a first portion (), a second portion () and a third portion (), every one of these portions () has a constant gradient (m, m m) of one steepness or a gradient (m, m, m) which is different from the constant gradient and has a curvature, and at least one of the constant gradients (m, m, m) has a steepness different from the at least one other constant gradient (m, m, m), or one of the different gradients (m, m, m) has a curvature that is different from the at least one other different gradient (m, m, m). 112478578101112101112123123. A mixing device () for mixing in a mixing vessel () , the mixing device having a stirring element () which has at least two stirring blades ( , ) which are of spiral form and which are connected to a motor-driveable shaft () , wherein the stirring blades ( , ) each have a first portion () , a second portion () and a third portion () , wherein each of the portions ( , , ) has a constant gradient (m , m , m) with a steepness or has a non-constant gradient (m , m , m) , which deviates from the constant gradient , with a curvature , and wherein{'b': 1', '2', '3', '1', '2', '3, 'at least one of the portions has a first constant gradient (m, m, m) with a steepness which differs from a second constant gradient (m, m, m) of another one of the portions, or'}{'b': 1', '2', '3', '1', '2', '3, 'at least one of the portions has a first non-constant gradient (m, m, m) with a curvature which differs from the a second non-constant gradient (m, m, m) of another one of the portions.'}21123123123123. The mixing device () as claimed in claim 1 , wherein the first constant gradient (m claim 1 , m claim 1 , m) has a greater or lesser steepness than the second constant gradient (m claim 1 , m claim 1 , m) or ...
