噴砂設備可用作對金屬的銹蝕層、熱處理件表面的殘鹽和氧化層、軋制件表面的氧化層、鍛造件表面的氧化層、焊接件表面的氧化層、鑄件表面的型砂及氧化層、舊機件表面等進行處理。噴砂設備還可以改變工件表面粗糙度，可以產生亞光或漫反射的工件表面，以達到光飾加工的目的。所以噴砂設備被廣泛應用于鑄造機械行業中。
如何選擇噴砂設備？要從以下幾個方面考慮：
1.一般而言，噴砂設備的效果主要由零件材料及噴砂磨料決定。根據零件材料的不同，噴砂磨料范圍可從效果強烈的金屬磨料到效果柔和的樹脂磨料，同時干噴砂與液體噴砂亦是重點考慮的因素。
2.生產效率確定噴砂設備種類。根據加工能力選擇自動化噴砂生產線、半自動化噴砂設備、壓入式噴砂機、吸入式噴砂機。
3.工件尺寸確定噴砂設備規格。根據工件尺寸選擇機艙大小，以便有足夠的空間完成處理工作。
4.壓縮空氣要求。根據噴砂設備規格確定空壓機容量，并留20%余量，以保護空壓機使用壽命。

Sandblasting equipment available corrosion layer, heat treatment of surface residual salt and oxide layer, the oxide layer on the surface of the rolling, forging, welding pieces of the oxide layer on the surface of the oxide layer on the surface of the casting surface, sand and the oxide layer, the old mechanical surface treatment. Sandblasting equipment can also change the surface roughness of the workpiece, can produce matte or diffuse to the surface of a workpiece, so as to achieve the purpose of finishing processing. So the sandblasting equipment is widely used in foundry machinery industry.
How to choose the sandblasting equipment? Should from the following several aspects to consider:
1 in general, sandblasting equipment effect parts from the main materials and blasting abrasive decision. According to parts of different materials, abrasive blasting can range from the effects of the strong metal abrasive to the effect of soft resin abrasive, and dry sandblasting and liquid sandblasting is also focused on the factors considered.
2 determine the efficiency of production of sandblasting equipment types. According to choose automated sandblasting processing capacity production line, semi-automatic sandblasting equipment, pressure-in sand blasting machine, suction type blasting machine.
3 workpiece size determine sandblasting equipment specifications. According to the workpiece size choose the cabin size, so that there is enough space to complete processing.
4 compressed air requirement. According to the blasting equipment specifications to determine the air compressor capacity, and left20% margin, in order to protect the service life of the air compressor.
