The ore milling equipment is an important equipment in the coal-fired power plant of the thermal power plant. The safety and stability of the ore milling equipment are directly related to the whole work of the whole thermal power unit. Therefore, the choice of the ore milling equipment construction plan is very important. ore milling equipment construction program in the 'trial operation of the tile' refers to the power plant in the medium-speed mill of the Ukrainian bearing in more than 60 ℃ high temperature work to maintain a stable state, not because of the bearing temperature and the export of lubricating oil temperature quickly high temperature Which led to increased vibration at the bearing seat and then melt, there is power plant mill operation in the 'tile' phenomenon. Only the ore milling equipment installation test 'trial delivery of the tile', in order to allow the entire fire power unit safe operation In addition, we introduce the ore milling equipment, we can understand the more refined the pulverized coal, which pulverizer The greater the value of the. Pulverized coal in the grinding machine to complete the work of grinding, the machine will be hot air blown into the boiler for full combustion, and coal combustion in the boiler will produce hot flue gas, these hot flue gas will flow around the boiler around the heat, And then follow-up separation of coal ash. Thermal power plant with medium-speed pulverizer for pulverized coal pulverized coal powder fineness and grinding efficiency has a very good protection, the fineness of the coal so much easier to burn in the boiler, can improve the use of coal Rate, reduce the possibility of environmental pollution.
