About

Bradley Pulverizer was founded in 1886 in Boston, Massachusetts. Our first single roll pulverizers were used in fertilizer plants grinding phosphate rock and in cement plants grinding raw material and clinker. To meet the growing demand of the fertilizer and cement industries, Bradley Pulverizer quickly expanded its pulverizing mill offerings.
