Coal ball 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.
Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grindable materials.
Accoridng to whether it need to add water during the grinding plant, Coal Grinding Mill can be divided into two types: dry ball mill and wet ball mill, wet ball mill is mainly used for the mineral processing plant, for example, copper ore processing plant, lead ore processing plant, antimony ore processing plant, gold ore processing plant, nickel ore processsing plant, etc; and the dry ball mill is mainly used for powder .
MILL COMPONENTS AT HIGH RISK OF DAMAGE As locked charge events subject the mill to massive forces, the majority of mill components are at risk including axial and radial pad bearings, axial and radial pad stools, trunnion bearing journals, mill heads, shells, critical fasteners, ring gear and the pinion. Some components will fail
Warm the mill to normal operating temperature of 150F mill outlet temperature (bituminous coal) and airflow at minimum (normal minimum primary air [PA] flow). Conduct a PA airflow measurement traverse by manual pitot tube to verify that the indicated PA is correct across the boiler operating range.
Two mill systems are employed for most coal grinding applications in the cement industry. These are, on the one hand, vertical roller mills that have achieved a share of almost 90 per cent and, on the other, ball mills whose share is recorded at just over 10 per cent1.
The wet ball mill grinding system was operated in open circuit, first grinding coal in No. 6 fuel oil and then grinding coal in water. The air swept ball mill grinding system was returned to service after acceptable specific energy more » values were demonstrated.
Mills are capable of grinding down to 90% minus 200 mesh as well as grinding a 40 hardgrove coal but at a lower rating. Units are equipped with all internal related grinding
The DEM was done to determine the profile of the grinding balls and raw coal for a full tube mill CFD study. The profile will be mapped as a geometry into the CFD model. A CFD study of a MPS 180 vertical spindle mill.
