The gunning machine type "ROTAMAT f" (refractory) is a continuously operating rotor gunning machine with a wide range of capacity and is well-proved in the refractory industry. Wherever great demands are made to the machinery technology with regard to dust-free and low-wear gunning of dry refractory concretes - the "ROTAMAT f" is used.
The gunning machine type „ROTAMAT f“ (refractory) complies with all relevant provisions of the machine directives 2006/42/EG, the low voltage directive 2006/95/EG on electrical equipment and the directive 2004/108/EG on electromagnetic compatibility.
The gunning material to be worked is fed through a hopper and a star-shaped agitator to the rotor. This rotor - fixed-ended between two sealing disks and driven by a rotary-current or compressed-air motor conveys the gunning material by the so-called thin-stream-method to the blow-off socket where it is blown into a hose or pipeline by compressed air.
Before being discharged from the line, the up to now dry or earth-slightly moist gunning material is mixed with water in the nozzle mixing unit.
The device operates with a blowing pressure from 0,5 to 6 bar and is able to transport the gunning material over a distance of up to 200 m.
Furthermore it is possible to operate the total installation by means of a remote control. In connection with the well-known Velco storage and charging systems the whole gunning procedure can be automated at a later stage.
The is nearly perfect for the processing of gunning material and has a performance range of 0,25 – 4,0 m³/h.
Efficiency, economic feasibility and particularly the machine technology are based on more than 45 years of experience in the field of gunning and torkreting technique.
