Coal mill is a machine that crushes and grinds the coal briquette into pulverized coal. It is important auxiliary equipment of pulverized coal furnace. During the coal grinding process, the coal is crushed and its superficial area increases continually.
pressurized seal air is also used to prevent leakage of coal dust from the mill and to protect bearings in the grinding rollers. MILL SYSTEM COMPARISON AND PERFORMANCE Refer to Table I for a summary of the design features for each mill system. Mill Comparisons—General The BTM is a lowspeed mill that primarily grinds coal by impact and attrition.
varies with mill types but are also largely influenced by coal feed rate, HGI variations, spring pressures, coal fineness, mechanical alignment of the grinding elements, bearing condition, optimum or reduced air/fuel ratios, etc. Our experience proves that monitoring mill HP/ton consumption for a given fuel HGI and/or mill fineness can
High circulating load is common in both reverse and direct ball mill grinding circuits. Why? Because the ball mill closed circuit is the last stage before separation.
