This document describes a marble pulverizer machine that can grind materials into fine powders between 150-3000 mesh. The machine has several advantages, including high efficiency (twice the capacity of other mills), long-lasting parts (rollers can last 2-5 years), safety, flexibility to adjust the fineness of materials, and environmentally-friendly operation. It works by using rollers to grind materials fed into the machine into fine powders that are then collected.
