Modular Roller Mill System Installed in Khazakstan

Modular Roller System Installed in Khazakstan - Williams Patent CrusherWilliams recently sold a DF-64 Pulverizer as part of a modular system. The mill and accessories were shipped to Alabama where the system was assembled and then dismantled for shipping to Khazakstan. The modular system has been reassembled at its final location and features our new heavy duty steel Roller Mill foundation. The Williams DF-64 Roller Mill is grinding 2” (50mm) x 0 barite, up to 4% to 5% moisture, to 97% minus 200 mesh (74 micron) product, dried to 0.2% or less surface moisture, at a product rate of 18 STPH (16.3 MTPH). Similar systems are currently in the works to ship to other locations around the world.

This is not the first time Williams has worked with a contractor to create a modular or mobile platform for one of our mills. If you have an application that requires special attention for a unique platform, we can customize mills and accessories to work for your application. Contact us today at (314) 621-3348 or email

Williams Roller Mills are Superior Direct Fired Pulverizers

Williams Roller Mills are Superior Direct Fired Pulverizers - Williams Patent CrusherWilliams sold a DF-43 Roller Mill to a major lime kiln manufacturer for a plant in Madagascar. The mill is to reduce minus 2” (50mm) bituminous coal with up to 8.8% surface moisture, 43 Hardgrove or softer, to a product 90% or more passing a 200 mesh square hole test sieve, drive to minus 1% surface moisture, at a product rate of 11,077 lbs/hr (5024 kg), dry basis to direct-fire a lime kiln.

The lime kiln manufacturer has found that their Williams Roller Mill is far more efficient than their previous roller mill, especially for flow control. According to startup personnel, this superior flow control is great for NOX control on a lime kiln.

The customer is pleased with their Williams mill and with the level of customer service they have received from Williams’ personnel. With NOX emissions being so stringent, the efficiency of the Williams Roller Mill is a valuable asset to any project and can be easily integrated into a new or existing lime kiln or other system. Equally important to quality products is great customer service and knowing Williams is dedicated to helping our customers achieve success. Contact us today to discuss your next project.
