Perlite Processing and MTW Trapezium Machine2021-08-30

Perlite is a kind of glassy rock formed by rapid cooling of acid lava from volcanic eruption, named for its pearl fissure structure. Perlite ore includes perlite, obsidian and turpentine.

The difference between the three is that perlite has circular arc cracks formed by condensation, which is called perlite structure, with a water content of 2 ~ 6%; Turpentine has unique turpentine luster, with water content of 6 ~ 10%; Obsidian has glass luster and shell fracture, and the water content is generally less than 2%.

Now SBM's MTW machine can grind perlite into 100-325mesh with very good performance.
