The automatic dry-powder mortar machine normally will use raw materials 3-6 tank, two big cans used to carry calcium powder, such as aniseed, the remaining small tank used for light calcium carbonate, calcium carbonate, such as sand, small. Light calcium carbonate, calcium carbonate, sand, small material needed to use the bucket elevator into a small tank, ingenious material distribution system supporting a bucket elevator distribution operations, thereby avoiding the waste of resources. Metering system coordinated by the metering screw, measuring bin hopper in the import of raw materials, through the sensor's data feeds to realize metering of raw materials.
