Similarly, like the mulling of green sand, you will need a predetermined amount of time to optimize the mixing the sand and binders to provide a homogenous sand mixture. Today, many foundries also utilize the continuous mixer for core making which as well provides good sand mixing properties that can be on demand or batched as required.

Sand Casting - slideshare

Sand castings are produced in specialized factories called foundries. Over 70% of all metal castings are produced via a sand casting process.[1] Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent (usually clay) is mixed or occurs with the sand.

The sand used in the sand casting process is typically bonded with bentonite and water to mold the sand. The sand can be recycled many times but each recycling requires the addition of bentonite and water. If the proportion of bentonite and water is not appropriate, the bonding strength of the sand mold would be reduced.
