The most commonly used one is equipped with two Σ blades, arranged in a side-by-side tangent differential speed type, that is, one stirring blade has a fast speed and the other has a slow speed, so as to generate a shearing force. Different blade speeds enable the kneaded materials to be sheared rapidly, so that the materials can be mixed evenly. In the production process of drilling fluid, a kneader is needed to knead the raw materials. The existing kneading equipment can only feed materials by gravity, and the feeding speed is slow.
