Williams Patent Crusher and Pulverizer Company

Williams Patent Crusher and Pulverizer Company is a leader in the crushing and pulverizing industry since 1871. We have over 500 patents and trademarks.

Williams Roller Mills pulverize or granulate and air classify chemicals, minerals, coal, limestone, phosphate rock, pigments, tobacco, clay, and barytes. Roller mills are also capable of drying with the addition of a heater. Williams's Direct Fired Mills pulverize coal and petroleum coke fuel for direct firing into boilers and kilns. The benefits of these mills are ultrafine size reduction with low operating cost and lends itself to automated process control, and is used extensively in coal fired boilers and kilns, limestone grinding facilities and the mining industry.
