Abstract
By rotating mixing blade units having blades inclined in opposite directions, pulverulent materials such as cement can be effectively mixed with a liquid under the most suitable condition to produce a desirable mixture. The blades of the mixing blade units are in spaced opposed relation to each other and formed so as to have their front edges spaced at a larger distance than their rear edges relative to the direction of rotation, thereby to cause the parts of the mixture around the respective mixing blade units to come into collision with each other between the mixing blade units. A mixture of high quality in which the pulverulent materials are uniformly dispersed without being left in the form of immiscible lumps with the liquid can be obtained.
