Abstract (en)
By rotating mixing blades (11, 12, 40, 41, 42, 51, 52, 61, 62, 71, 72) having blades being 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 mixing blades are opposite to each other and formed so as to have their front edges being larger in distance than their rear edges relative to the direction of rotation, thereby to cause the parts of the mixture around the respective mixing blades to come into collision with each other between the mixing blades. The 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. <IMAGE>
