Dust Removal from Foundry Sand!!!!
Thermfire with it's two fluidized beds and large volume of fluidizing air is easily the best classifier money can buy. If you want to clean up the silica dust from your foundry air then start at the source with a Thermfire Thermal Sand Reclaimer.
even new sand has a lot of dust from the high impact created by the blower truck...Thermfire will remove this dust.
Thermfire puts about 40% more air through the fluidized bed of sand and with it's automatic dust collector system the dust is all removed from your sand.
