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 machine that has been tested and approved according to ZTV-SIB 90 is nearly perfect for the processing of SPCC mortar and has a continuously adjustable 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.
Our gunning machine ROTAMAT tb with corresponding equipment is tested and approved especially for the refurbishment of concrete constructions with listed SPCC products.
