The Projection Line equipment attain extremely high levels of productivity compared with the traditional method improving the cost x benefit ration of their investment a lot, with greater operating speed and less waste of material. They produce a more compact mortar, with a reduced level of cavities due to greater adherence to the surfaces and uniformity in the application through an adjustable flow system and suitable adjustment of the mixture. Indicated for execution of application of roughcast, plaster, single layer, cellular concrete besides transporting mortar for projection, grout for filling blocks and mortar for self-leveling floor. It allows granulometry of up to 10mm, the greatest in the market, with an activation panel with a protection system for motors, and comes with 2 shaft units for projection and several gauges of projecting nozzles, a pump with adjustment of wear in the stator, with a pressure gauge for monitoring pumping and pneumatic wheels. It projects up to 50l/minute at a distance of 20m vertically and 40m horizontally.
