• Salient Features: Cooling system ensure constant temperature and moisture to the return sand Sand movement effected by the fluidization property of sand and vibratory motion Etc

Return Sand Temperature, after the vibratory shake out in a mechanized green sand foundry is around ZOOGC. The sand temperature is highest arbacent to the metal surface and lowest away job it. The quantity of heat to be removed depends on the sand to metal ratio and the holding time of metal in the mould. The return sand temperature at the inlet of the cooled after passing through conveyor is around 1 OOOC. Mould of good quality and clean casting surface require well cooled sand. Sand Cooling requires a continuous and uniform flow to achieve the uniform flow and compensate for irregular Sand supply the sieved hot return sand is stored in a surge hopper from there; a belt transports the hot sand to the cooling conveyor which is designed with a perforated bottom plate. Fresh air is blown through the preparation holes and at the same time water is sprayed on to the sand from nozzles located above the conveyor vibrations of the conveyor and turbulence caused by the air blown through ensure that sand water mix well so that The water evaporates and the sand is cooled. The belt, the cooling conveyor and the sand spraying unit are controlled by level indicators located in the surge hopper the plant operates only if the sand in the surge hopper is between the maximum and minimum level.

This process derives its name from the presence of moisture in molding sand and is indicator of the unbaked nature of the mould. Raw sand is obtained and processed to provide a consistent distribution of grain sizing. A variety of additives such as pitch, cellulose, and silica flour are used in the process. This process of molding offers a great deal of flexibility in pattern design and consequently in the mould design at very economical costs. At VJP, we have adapted the green sand process to mechanical and automated production methods to ensure speed and efficiency. Features Low material costs Reclaimable mould material. Environmentally friendly. Ensures strong and rigid moulds. Advantages These molds are relatively inexpensive to produce, since the basic material is readily available. Complex patterns can be accommodated in the in the mold design, at affordable costs. Easily adapts to automated production methods.
