At The Processing Location. Perlite ore is further reduced in size and sent through a rotary kiln dryer at 120 – 175°C (200 – 350°F) to drive off "free" moisture on the exterior of each particle. The drying process is carefully controlled to keep from overheating the ore and driving off the "combined" moisture which allows the ...

Crude perlite is mined using open-pit methods and then is moved to the plant site where it is stockpiled. Figure 11.30-1 is a flow diagram of crude ore processing. The first processing step is to reduce the diameter of the ore to approximately 1.6 centimeters (cm) (0.6 inch [in.]) in a primary jaw crusher. The crude ore is then passed through a ...

Perlite has been used for insulative, fire-resistant plasters and spray-on cementitious coatings since the 1940s, with well-documented results and proven mix designs. Performance specifics depend greatly on the design, installation, and the materials used. Applications include interior structural steel framing such as columns, beams, and ...
