Type of STAS

Manual System

Dry mortar unloaded from silo through the tap manually. And then the mortar is prepared to be stirred manually as usual.

D-40/D-50 Mixer Gravitation System

Mixer fitted under  silo. Dry mortar from the silo into the mixer without pumping (force of gravity). Mixer output: 2.4 to 3 m3 of wet mortar.

Silo Conveying System

A vertical distribution system of dry mortar from silo using compressor. Mortar pumped through a rubber hose to a height of more than 150m. The dry mortar transfered into mixer at the job site with output: 1.8 m3 of ready-made mortar
