Sand Core Heated In India

2019-4-1 · If the sand is not fluidized after the cycle, the resonant heat in the elements will build up in the sand immediately around the elements. This not only causes inconsistent sand temperature, but also shortens element life. By shutting off the sand going into the unit, sand exiting the unit will also stop (a principle of the fluidized bed).
