| Abstract: | The sand processing equipments were reformed to improve and stabilize the sand quality of product line, and the influencing factors of sand performance were analyzed. The sand quality is improved by the control of sand properties, and the ratio of effective bentonite content and moisture content, the ratio of compactability and moisture content are more reasonable. The rejection rate of crush and blowhole is reduced greatly. |
