Sandblasting Pretoria – Portable Blast Equipment:

Mobile dry abrasive blast systems are typically powered by a diesel air compressor. The air compressor provides a large volume of high pressure air to a single or multiple “blast pots”. Blast pots are pressurized, tank-like containers, filled with abrasive material, used to allow an adjustable amount of blasting grit into the main blasting line. The number of blast pots is dictated by the volume of air the compressor can provide. Fully equipped blast systems are often found mounted on semi-tractor trailers, offering high mobility and easy transport from site to site. Others are hopper-fed types making them lightweight and more mobile. In wet blasting, the abrasive is introduced into a pressurized stream of water or other liquid, creating a slurry. Wet blasting is often used in applications where the minimal dust generation is desired.
