砂再生、颗粒净化的工艺流程设计

备受关注的铸造废旧砂再生处理是一个有工艺特性、相对独立复杂的工艺处理过程。针对中小规模铸造砂处理过程中的旧砂再生,其生产流程可以通过选择干法+热法+干法的综合处理方法,使大量废、旧砂复原、净化转化成优良品质的再生回用砂,或作为商品去替代原、新砂使用。如造型制芯砂、覆膜砂、壳型砂、V法铸造和消失模用砂等不同类型的铸造生产场合。

Process design of sand regeneration and particle purification

Recycling of foundry waste sand is a relatively independent and complicated process with process characteristics.For the regeneration of used sand in the small and medium-sized foundry sands processing,the production process can choose a combination of dry+thermal+dry processing methods to restore and purify a large amount of waste and used sand into good quality recycled sand,or as a commodity to replace the original and new sand,in modeling core sand,coated sand,shell sand,V method casting and lost foam sand and other types of casting production occasions.
