The growth rate of electricity consumption is expected to rebound, and the installed capacity of non-fossil energy will increase.

Coal Mill Network News: On April 29, Ouyang Changyu, Deputy Secretary-General of the China Electricity Council, stated at the 2015 China Power Development Forum that the growth rate of electricity consumption is expected to generally rebound in the second, third, and fourth quarters of this year. Considering factors such as the macroeconomic situation, temperature and base numbers, the reduction of electricity prices for industrial and commercial use, and energy substitution, it is expected that the growth rate of electricity consumption in the last three quarters will generally rebound. It is estimated that the total electricity consumption in the first half of the year will be 2.68 trillion kilowatt-hours, a year-on-year increase of about 2%; the total electricity consumption for the whole year is expected to be 5.69-5.80 trillion kilowatt-hours, a year-on-year increase of 3%-5%. The power supply capacity is sufficient, and non-fossil energy.

How to reduce the electricity consumption of vertical mills

The vertical mill is an energy-saving and consumption-reducing grinding equipment. In recent years, the technology of vertical mills has developed rapidly, gaining favor from many cement production enterprises and becoming the main equipment in grinding systems. The maximum load of the vertical mill system mainly comes from the main motor of the mill and the circulating fan, with the electrical load accounting for about 70% of the total electricity consumption of the vertical mill system. Therefore, the key to effectively reducing the system's electricity consumption lies in how to reduce the electricity consumption of the main motor and the circulating fan of the vertical mill system. How to reduce the electricity consumption of the vertical mill 1. Selection of the optimal parameters for energy consumption of the vertical mill system The principles of vertical mills are generally similar, but due to different process conditions in various enterprises, different raw material characteristics, and operating parameters,

What are the reasons for the excessive temperature of the ball mill bearing?

What causes the phenomenon of excessive temperature in the ball mill bearings? This article provides a detailed analysis of this issue, as follows:  1. The viscosity of the lubricating oil changes with the increase in usage time, leading to a decline in oil quality, which affects the formation of hydrodynamic lubrication and thus impacts the lubrication effect, causing the bearing temperature to rise.  2. The sliding bearings used in ball mills are relatively large, and they usually have powerful cooling devices. If the cooling device malfunctions, such as clogging, it can lead to poor cooling effects, which may also cause the bearing temperature to rise.  3. The cooling water pipes of the ball mill sliding bearings and the lubricating oil pipes are within the same casing.

Guohua Power's coal mill and boiler combustion technology have passed technical appraisal.

Recently, the China Electromechanical Engineering Society held a technical appraisal meeting for the project "Research and Application of Boiler Combustion Technology for Ultra-High Moisture Lignite in Medium-Speed Grinding Systems" in Beijing. This project is led by Guohua Electric Power Company, with participation from Guohua Electric Power Research Institute and Shenhua Guohua (Indonesia) South Sulawesi Power Co., Ltd. Through adjustments in boiler combustion and coal mill operation, the project successfully achieved the combustion of ultra-high moisture (52-54%) low-quality lignite in medium-speed grinding boilers, completely resolving a series of major safety and environmental issues caused by coal drying, allowing the power plant to turn losses into profits and bringing honor to the country. Vice President of the China Electric Power Planning and Design Institute.

About grinding balls

Currently, the widely used types of grinding balls both domestically and internationally are high carbon high alloy cast grinding balls and high carbon low alloy forged or cast grinding balls. In dry production processes such as thermal power plants and the cement industry, the vast majority use high and low chromium cast iron grinding balls. In the wet processes of mining, high carbon low alloy grinding balls are more commonly applied. There are many types of grinding balls in the domestic market, and due to the imperfections of the market economy, the use of grinding balls is not determined by process efficiency, leading to a high degree of randomness. The main varieties include chromium-based high alloy cast iron types, such as Cr8, Cr12, Cr15, Cr18, Cr24, Cr26, and low chromium cast iron types, such as Cr2 and martensitic cast iron.

The coal mill in the coal industry continues to make efforts.

Coal is the main energy source in our country and is an indispensable material foundation for national economic and social development. Coal plays an important role in our country's energy structure. Coal resources have also been in high demand, showing a significant need for coal mills. In addition, with the vigorous development of the coal industry and the promotion of clean coal technology, secondary conversion equipment such as coking, liquefaction, and gasification of coal will also develop rapidly. It is imperative to develop and manufacture large-scale coking equipment, large-scale coal liquefaction containers, and large-scale gasification furnaces.   Mr. Bai Yinghui, the chief engineer of Liming Heavy Industry Technology, based on many years of experience in mill research and development, combined with years of experience.

China Coal Industry Association: Coal supply exceeds demand for the whole year

The China Coal Industry Association recently stated that there are some signs of stabilization in the coal market, but the economic operation of coal has not shown a significant rebound. It is expected that the annual growth of coal production capacity will exceed the growth of demand, and imports will remain high, with pressure from supply exceeding demand still very significant. Since May, the growth rate of national coal demand, production and sales, and transportation volume has significantly declined, while net imports have continued to grow rapidly, leading to an increase in overall inventory, a sharp decline in the coal price index, and a significant drop in the market prosperity index. In analyzing the main reasons affecting the current changes in the coal market, the China Coal Industry Association pointed out that the first reason is the continued global economic downturn and increasing domestic economic difficulties.
