Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

When water droplet is added into the feed it does not evaporate as easily as the water added by steam, it will remain as a moist spot in the feed resulting in rotting and the bacteria growth due to increased water activity. That is why water is often applied together with a surfactant that will reduce bacterial growth.

That's why we include a gap so air can flow on both sides of the brick which drys it evenly. Moisture soaked into the brick will drain out both sides, the face side and the back side which faces the house. You don't want water draining into the house so with this design it drains into the gap so no water can touch the house.
