For the typical applications, sandblasting equipment comes with blaster nozzles and also an air compressors in order to propel abrasive in high pressures. Depending where it will be used for, the type of grit varies.
Some of the common types of grits that are being used for sandblasting would include aluminum oxide, copper and iron slag, glass beads, shells of walnuts and crushed glass.

Steel grit likewise are used for treating rough and aggressive surfaces.
Roughening and Cleaning Purposes
The rusty surfaces, surface scales and aging, burred components, machine wear and tear are some of the common issues which a lot of industries face. This is where sandblasting equipments play an important role in prolonging the life of machineries and equipments. This is going to allow an easy removal of rusts and for the preparation process of surfaces for the applications of coatings and paint. If there’s no paint, lustre and also a perfect finishing, products could never appeal customers on the highly competitive market. Before the application of paint layers, sandblasting could remove surface imperfections, which then gives a smoother appearance.
Carving and Shaping of the Surfaces
With wear and tear, any metallic component could go out of shape. Another common use for a sandblasting equipment is on monument letter engraving for cemeteries. A three dimensional signing can be acquired with sandblasting, which can in fact provide more satisfaction towards customers compared to flat signs. Sandblasting also could be utilized for artwork. Buildings are actually refurbished by using sandblasting equipments. For a wood signage, the rings which are on the wood are made significant from the grains through the process of sandblasting that could then give a pleasing appearance. The words and images can be carved through the process of glass etching. This kind of effect is known as snowing of glass, that will make it semi-opaque.
Sandblasting equipments can in fact be used for different purposes, which in fact includes commercial and residential cleaning as well as on industrial shaping or for the purpose of resurfacing applications.
