Developing Cleaning Rooms that Eliminate Airborne Silica

 · Improving Shakeout Methods to Control Silica Dust. One of the "easiest" ways to make cleaning rooms safer is by implementing equipment such as enclosed sand-casting conditioners and cooling conveyors. These systems are often automated and closed-off allowing the castings to remain contained during shakeout and carryover.
