GreenSand Preparation Equipment

According to the castingplant layout, technical requirements and various molding lines, the green sandpreparation equipment layout varies a lot. Its process flow is composed of usedsand recovery, used sand crushing and screening, used sand cooling, clay andcoal powder conveying, new sand conveying and molding sand mixing.

1. Used Sand Recovery
The used sand is collected by a sand hopper after sand shakeout and conveyed tothe next sand screening process by the conveyor. Scrap iron and iron splashingwill be separated by magnetic separating equipment during the process of sandconveying.

2. Used Sand Crushing andScreening
The used sand is conveyed into the sand screening equipment which can crush andscreen the sand lump among the used sand. The remaining sand lump that cannotbe crushed will be screened out. At the same time, the micro power will bedrawn out by induction fan. Finally, the qualified used sand flows down to thenext process.

3. Used Sand Cooling
The hot used sand containing micro power will be cooled in the coolingequipment. There are two cooling modes: wind cooling and water cooling. Themicro power is drawn out by an induction fan.

4. Clay and Coal Power Conveying
Clay and coal power will be conveyed to the material hopper above the sandmixer through the pneumatic conveyor and then be added to the sand mixer incertain ratio after the accurate weighing by electric scale.

5. New Sand Conveying
According to different technical requirements, new sand and used sand can bemixed in a predetermined ratio before being conveyed to the material hopper, orthey can be mixed in a certainratio after they are separately conveyed to the material hopper above the sandmixer.
