[0002] Foundry sand is a granular refractory material used to prepare molding sand and core sand in foundry production. Direct discharge of used foundry sand will lead to waste of resources and environmental pollution. Therefore, it is necessary to recycle and reuse the used foundry sand. In the recycling process, crushing devices are now mostly used to complete the crushing of foundry sand. In actual use, it has the advantages of simple operation, stable structure and good use effect.

The sieve holes arranged on the lower end plate are used to screen and filter the crushed materials in the crushing chamber, and the materials smaller than the aperture size of the sieve holes are transported downward through the feed tray, thereby improving the screening and filtering performance of the crushed materials and preventing impurities with larger particle diameters from being mixed and recovered with the used sand.

[0004] In the above utility model, when the old foundry sand falls into the feed port and is discharged through the sieve hole, dust will float. Adding an electrostatic precipitator will increase the investment cost of this utility model.
