In this cement plant system, the material specific surface area of the ball mill is more than 300m2 kg (particle size 50 m), and the working efficiency of the roller mill section is increased, and the actual power used in the roller press section reaches 9kwh t, while the actual power used in the ball mill section drops to 11kwh t.
In this study, separator rejects of a closed circuit cement tube milling were dry ground in a 10l pilot scale vertical stirred mill. tests were done as open and closed circuit.
However, at 6.1–21 and 38–879 μm ranges stirred mill product has 2.7 and 5.6 extra mass, respectively. if ball mill product is compared to the cement, the main difference occurs at 0.25–38 and 38–879 μm size ranges. the former is the amount for.
There are efficiency factors for dry grinding, open circuit ball milling, mill diameter, oversize feed, grinding finer than 75 microns and too large or too small reduction ratios. for cement application, the dry grinding (ef1), mill diameter (ef3), oversize feed (ef4) and fine product (ef5) factors are relevant.
Limestone ball mill at rs 400000 unit ball grinding mill . ball mill introduction the ball mill is a key equipment for grinding materials widely used in powdermaking production line such as cement silicate sand newtype building material refractory material fertilier ore dressing of ferrous metal and nonferrous metal glass ceramics etc. details.
2) ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. when the grinding conditions differ from these specified conditions, efficiency factors (rowland and kjos, 1978) have to be used in conjunction with equation 1.
Mined limestone is delivered to the crusher for crushing by the belt conveyor, limestone after crushing ,clay, iron powder etc will be ground into powder by ball mill or vertical mill, and then transported by air delivery chute to raw meal homogenization silo for storing and further material meal shall get into the preheating decomposition system after homogenization where.
Of course, even if we set a more appropriate cement fineness, it is difficult to change the current situation that the flow velocity in the opencircuit ball mill is only 1213 of that in the closedcircuit ball mill with the same specification, which will lead to poor comprehensive performance of finished cement, low system output and.
