From our original E/EL ball-and-race type pulverizers for lower capacity applications, to the latest B&W Roll Wheel™ pulverizer capable of grinding up to 230,000 pounds of coal per hour (104,300 kg/hr), we set the standard for high availability, reliability and low maintenance.
INTRODUCTION TO BOWL MILLS: Coal is the one of the most dominating energy source because of its cost, availability and transportability. Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of low-grade coals.
Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
