The appliance for preparing mortar consists of a storage compartment (7) for the dry mortar , a mixer compartment (24) with inlet (21) and outlet (13), liquid-feeders for water, and feeders for dry mortar into the mixer compartment. A mixer mixing the dry mortar and liquid in the mixer compartment consists of a rotary shaft (22) on which are paddles (23) and extending from the inlet to the outlet. The paddles are shaped so that when the mixer turns they exert force at right angles to the pivot axle on the materials in the mixer compartment. |
