How to choose the furnace for vertical mill? Currently additional coal-fired furnaces have two options: First, choose a coal fluidized bed furnace; the second is to select pulverized coal stove. Comparing the two, the roaster has the following advantages: 1, high energy consumption, can be adapted to low-quality coal; 2, NOx content is lower than the national standard; 3, no-cost desulfurization 90% in the combustion process; 4, SO2 desulphurization After lower than the national standard; 5, in the ignition, shutdown standby, the boiling furnace ignition slow, you can press the fire 8 ~ 24h roaster, restart without ignition; 6, roaster no danger of explosion, but every time the ignition has pulverized coal furnace danger; 7 February roaster just around the construction cycle, pulverized coal fired boilers will need three to four months time; 8, small footprint, low investment. Slag grinding and delivery of this workshop is an annual 300,000 tons of slag powder production line slag grinding and conveying section. Slag from the slag unloading conveyor workshop delivered to the mill slag, slag good after grinding through the precipitator filtration, by air delivery chute, bucket elevator to the slag powder library; incompletely milled slag through the chain conveyor , bucket elevator and then back into the mill to continue grinding. Slag vertical mill's drying heat sources provided by the efficient vertical mill roaster roaster masonry, application-based calorific value of coal requirements 2000Kcal / kg or more, you can use low-quality coal. Slag grinding model MLK2650 type vertical mill, the production capacity of 50t / h slag powder. Requirements into the mill size ≤50mm, moisture ≤15%, fineness> 400m2 / kg, the amount of wind mill for 79000Nm3 / h dryer roaster, into the mill air temperature is 220 ~ 260 ℃, up to 350 ℃, the largest import and export pressure difference 5000Pa, disc diameter Φ2650mm, disc speed 31.87r / min, a total of three grinding rollers.
