|Title||What are the main factors affecting the yield of garnet ultrafine grinding?|
Garnet powder preparation is cement, power plants, metallurgical and other departments of the important processes to improve the coal production is the inevitable requirement of high yield and energy saving. In addition to the selection of the appropriate type of coal mill equipment, garnet ultrafine mill operation, but also need to continue to optimize the operating parameters to ensure the safe operation of ultra-fine grinding system. The main factors affecting the yield of garnet ultrafine grinding.
1, into the grinding garnet moisture
Into the grinding garnet water, easy to cut off the material slippery, in the winter when the easy warehouse, easy to produce in the mill ball, when the garnet ultrafine grinding when the low yield. In operation should try to improve the garnet ultrafine grinding inlet temperature, to strengthen the grinding ventilation, to ensure that the grinding of garnet powder fineness of qualified.
2, grinding body loading
Grinding body less, the performance of the mill material, garnet ultra-fine grinding of the current low, Taiwan's low yield. Should be promptly to the mill to add grinding body, depending on the garnet ultrafine grinding current to normal, so as to improve the output when Taiwan. Reasonable grinding body gradation. To increase production.
3, garnet ultra-fine grinding of the inlet temperature
Ultra-fine grinding of the population temperature is low, garnet ultrafine mill production decline. In the kiln system to meet the stability of the thermal system under the premise of the grate bed material layer control slightly thicker (should be regarded as the kiln clinker case), open a large corresponding grate cooler valve opening to improve the grinding Wind temperature, improve the yield of garnet ultrafine grinding. Will be into the ultra-fine grinding of the hot air part of the pipeline to transform, to meet the requirements of space layout, as far as possible the original part of the bend pipe straight, to strengthen the seal at the junction of the work. In order to prevent the hot air pipe to the outside heat, the outer package of a layer of asbestos, and then white iron bag, both beautiful and practical. This can greatly reduce the heat loss to the ultra-fine grinding hot air duct, thereby increasing the hot air temperature at the entrance, ultra-fine grinding of the inlet temperature has been able to reach more than 400 ℃, to meet the requirements of ultra-fine grinding to increase production.
