Mobile blasting

Keeping operational costs as low as possible can be achieved by Gritco’s accurate abrasive setting possibilities and exact metering valve (no slow starting shot). High performance, reliability, easy-to-operate and low maintenance are additional advantages of Gritco’s high quality blast pots.

Trouble-free blasting with high quality surface results (ready for further processing) starts with dry air. Gritco’s aftercoolers (possibly extended with filters) are designed to prevent blast pot blockage with the best possible air for small, mid-sized or large blasting systems.

Of course, the blasting operator has to be effectively protected from high speed rebounding abrasives and occurring dust. For this Gritco supplies comfortable, 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. As reclaiming and recycling wet abrasives is too complicated, one-pass-abrasives such as Red Garnet, Glass Granulate or Aluminium Silicate (slag) are commonly used to remove rust and paint. The degree of contamination and required result (e.g. surface roughness) determine the abrasive grain size, which should be as small as possible to optimize the cover rate and therefore the blasting speed.

“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.
