The invention relates to a mixing and conveying system for dry mortar materials. The dry mortar materials can be obtained from a storage silo (1) through an openable closure panel (3). A pipe (17), in which a drivable screw conveyor (4) is mounted, is arranged under the closure panel (3). The pipe (17) leads into a mixing and buffer container (18), in which a coil (20) is rotatably mounted on a central axis (19). The mixing and buffer container (18) has a volume which equals at least 1.5-times the minute capacity of the pump-screw conveyor (14). It is thus ensured that the dry mortar material is mixed therein with the added water for at least 90 seconds or longer. The mixing and buffer container (18) leads into a pipe (15) at the bottom having a pump-screw conveyor (14) which conveys the mixed mortar into a hose (5). The pump-screw conveyor (14) can be allowed to run backward. The coil (20) runs continually such that the mortar is constantly agitated to prevent setting.
A mixing and conveying facility for dry building materials able to be obtained from a supply silo (1) by way of an openable and closable closure flap (3), with a drivable conveying screw (4) which is arranged below the closure flap (3), is mounted in a pipe (17) and is for withdrawing dry building material, characterised in that a tempering and buffer container (10, 18) with a fitting (8) for adding water as well as with an inner, drivable stirrer or with a spiral (20) is arranged after this conveying screw (4), and the tempering and buffer container (10, 18) at the bottom runs out into a channel or cone and into a pipe (15) with a pump conveying screw (14) with its own drive (16), via which pump conveying worm the mortar mixture processed in the tempering and buffer container (10, 18) can be conveyed into the pump hose (5), wherein the content of the tempering and buffer container (10, 18) is at least 1.5 times the maximal minute delivery output of the pump conveying screw (14).
