Raymond coal mill, also known as Raymond mill, Raymond roller mill, is a new type of mill that replaces ball mills to process coal powder. The roller of Raymond coal mill is tightly pressed on the grinding ring under the action of centrifugal force.
Roller mills use the centrifugal force of cylindrical grinding rolls to crush material into a uniform particle size and grind, dry, and classify. Some of its typical applications include the grinding, drying, and classifying coal, gypsum, limestone, clay, barite, pearlite, clinker, food products, grains, ores, and more.
To understand the performance of a vertical roller coal mill, the real operational tests have been performed considering three different coal sources. Obtained results indicate that grinding pressure, primary air (PA) temperature and mill motor current have a tendency to rise by increasing coal feeding mass flow rates for all used coal.
