Casting Defects - Sand Mold, Metal Casting - Iron foundry

4. Sand Hole Defect. Sand hole is a type of typical shrinkage cavity defect. You could see the empty holes after sand blasting or machining process. The sand dropped from sand molds, rolling into the liquid metal, then caused sand holes. It is the problem of sand mold, or the flow speed of the metal is too high, so could be solved by foundries.

What Is Sandblasting? | OneMonroe

Also known as abrasive blasting, sandblasting is a surface finishing process that involves the use of a powered machine — typically an air compressor as well as a sandblasting machine — to spray abrasive particles under high pressure against a surface. It's called "sandblasting" because it blasts the surface with particles of sand.

Industrial treatment processes for the recycling of green foundry sands

The reclamation treatment is based on a dry mechanical process: the dried sand grains are fed between metal blade drums that rotate at 1 rpm and a stone grinding wheel, which rotates at 40 rpm, thus obtaining the break of the oolitic shell and the rounding off of the silica particles. A scheme of the plant is shown in Figure 2.
