add to favorites Adjustment of fineness of finished material in production of ultrafine mill Pc  

The first factor determining the fineness of the ultrafine Mill's finished material is the distance between the mill roller and the grinding disc, and the distance between the two determines the size of the abrasive material and the size of the fineness of the finished material. The size of the spacing between the grinding roller and the disc of the ultrafine mill needs to be adjusted by the limit device in the ultrafine mill. The limit device in ultrafine grinding is designed to satisfy the requirement of the fineness of the material, and to avoid the abrasion of the direct contact between the grinding disc and the roller. ultrafine Mill Milling Machine Because of the required fineness of the finished material is different, and this kind of fine size adjustment depends on the grinding disc and the spacing between the rollers to achieve, so installed the limit device. When the spacing between the grinding disc and the roller is larger, the material is not sufficient and the grain is larger, when the spacing between the two is changed to an hour, the fineness of the finished material becomes thinner.

The other factor determining the fineness of the ultrafine Mill's finished material is the speed of the powder separator. The rotating speed of the separator has played a second check function, when the milled material with the wind is taken to the powder separator, some materials can be selected by the powder machine, while others can not, which played a role in the selection of powder, Also played a role in determining the size of the fineness of the finished material. The speed of the separator in the ultrafine mill can be adjusted by itself, and when the speed of the machine is high, the same fineness of the material and the same large wind can not be through the selection of powder machine, can only fall into the grinding chamber once again grinding, and the fineness of the material is small particles in the same speed and the same wind action can be selected by the powder machine, In order to achieve the purpose of powder selection, but also to complete the adjustment of the fineness of finished material.

In addition to the above factors can affect the adjustment of fineness of finished materials, the various properties of ultra-fine grinding and components and other factors will affect the fineness of finished materials. When the mill rollers and the grinding disc wear because of abrasive materials and abrasion or powder machine wear will lead to the changes in the fineness of the finished material, users need to pay attention to timely and timely maintenance.

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.
