Blasting rooms

Ease of use, low maintenance, high production output and reliable performance are complemented by minimal refilling interference. This last feature is obtained by the large blast pot contents and the 100% closure of the filling assembly when the blast pots are placed under an abrasive silo.

The blasting operator has to be effectively protected from high speed rebounding abrasives and occurring dust. For this Gritco supplies innovative, comfortable to wear, easy to use, air supplied blasting helmets. High quality gloves and overalls - all according to strict EC rules – are also part of Gritco’s extensive range of blasting gear.

The type of material and treatment of an object define the abrasive’s sort and size. In blasting rooms the abrasive in general can be recollected so recyclable abrasives are mostly used. The degree of contamination and required result (e.g. surface roughness) determine the abrasive grain size. This should be as small as possible to optimize the cover rate and therefore blasting speed.

To ensure a blockage free, constant abrasive dosage and better surface quality (for further processing like paint spraying), blasting with dry compressed air is essential. This is achieved with an compressed air dryer delivered by the supplier of the compressor.

“More power means more work” is especially true for the last part of the blasting chain: the compressor. More air means faster progress simply because of the possibility to use larger nozzles creating larger blasting patterns. Therefore compressor capacities can vary from 2 to 10 m3/min.
