Crushing Equipment / March 11, 2023 / 5 minutes of reading. An impact crusher is a machine used to crush materials by impact energy. It works by feeding the material into a rotating rotor, which is equipped with a series of hammers. As the rotor spins, the hammers strike the material, causing it to break into smaller pieces.Web

Perlite is a volcanic rock mined in the United States, as well as other countries like China, Greece, and Italy. The volcanic glass, or perlite, is formed when lava (molten rock) spews out of a volcano, and cools in a rapid manner. Because of rapid cooling, water is trapped within the rock, and the lava forms into a glass-like structure.Web
As the pumice volume increased, the mortars' drying shrinkage and sulfate-induced expansion values decreased significantly.
