Learning nugget: Green Molding Sands

SUMMARY:

Proper sand mill management requires knowledge of green molding sand and the other elements that make up the sand circuit, the functions of each of these elements, effective maintenance of these functions, the ability to reuse spent sand, avoiding losses of this material, considering sand as a valuable process tool, and considering the sand mill circuit an important step in the manufacturing process.

It is of grat significance to study the sand mill’s capacity, that is, to determine the number and capacity of the sand mixture-producing elements, to understand the elements that consume these prepared sand mixtures, to compare the sand consumption capacity, that is, the production speed of the lines versus the sand production of the mixers, to determine the nominal and maximum capacity of the sand mill, and to understand its margins.

This will ensure the continuous production of sand mixtures with the appropriate properties, assuming variability in line with the quality requirements of the parts and the resources available at the plant itself. It will also preserve and maintain the appropriate properties of the manufactured molds and cores before and after the casting process, and compensate for variations inherent to the manufacturing process, minimizing their effects on the mixture properties.
