| Abstract: | The compaction rate of the moulding sand is an essential index showing the sand moisture in casting practice.A concrete theoretical analysis is made for the automatic adjustment and control system of the sand compaction rate,and this system is related with the various requirements of moulding sand preparatiorn.And such system is successfully applied to the production practice. |
