Materials & Industries

As specialists in the design, manufacture, and commissioning of pulverizing systems for fine and semi-fine grinding, Bradley Pulverizer has equipment operating across six continents in a variety of industries and applications.

Producers of ores, coal, clays, cement, fertilizers and many other minerals rely on Bradley mills for uninterrupted heavy tonnage production of materials which meet the most demanding specifications for particle size distribution.

Since 1886, Bradley pendulum roller mills have been recognized as the best in class pulverizing solution for the mineral processing industry.  Our mill systems range in output from 1 to 150 tons per hour with adjustable and uniform particle sizes from 50% passing 150 microns to 100% passing 30 microns – all in a single pass.  Our experienced engineers can design a custom mill system solution configured to meet your specific application needs.
