摘要： A mixing apparatus for preparing mortar has a screw conveyor for conveying dry material, such as a mixture of sand and cement, from a storage vessel to a mixing chamber. The mixing chamber has an inlet end, adapted to receive dry material from an outlet end of the screw conveyor, an outlet end for dispensing wet mortar, and a water feed between the inlet and outlet ends for delivering a metered flow or quantity of water into the mixing chamber. A mixing device within the mixing chamber mixes the dry material and water and controls passage of material from the inlet to the outlet end. The outlet end is located above said inlet end so the dry material falls under gravity from the outlet end into the mixing chamber, maintaining separation between the dry material in the screw conveyor and the wet material in the mixing chamber.
