Winner particle size analyzer technology helps the 22nd China International Cement Technology Exhibition

Exhibition

From October 9 to October 12, 2021, the 22nd China International Cement Technology and Equipment Exhibition 2021, hosted by the China Building Materials Federation, China Cement Association, and China Council for the Promotion of International Trade Building Materials Industry Branch, will be held in Jiangxi Nanchang Greenland International Expo Center grandly opened. Jinan Winner Particle Instrument Co., Ltd. brought the Winner3003 dry laser particle size analyzer to the scene, attracting a large number of customers to visit and inquire.

Industry Trends

The economic operation of the cement industry in 2020 will be characterized by "sudden decline, rapid recovery, and stabilization". The year-on-year growth of cement production and sales has turned from negative to positive. In 2020, cement production reached 2.377 billion tons, a year-on-year increase of 1.6%, maintaining a high plateau period. Demand will maintain a "platform" in 2021, and multiple factors including environmental protection will continue to compress supply. The price and efficiency of the cement industry will continue to be at the level of the past two years, and mainstream market prices will remain strong.

The important influence of particle size distribution on cement properties

As we all know, when the raw materials and firing conditions are determined, the particle size determines the performance of cement. At the same time, the particle distribution of the material can also be used to judge the performance of the grinding system. Therefore, the measurement of particle size distribution is not only an effective way to control the fineness of cement particles. method, and more importantly, it will provide an accurate basis for the optimization of grinding, grading and other links. The particle size distribution of cement will greatly affect the strength of concrete. The measurement of particle size distribution plays a great role in the quality control of the final product and how to optimize the production process during the production process to improve the quality of the product, while also reducing energy consumption and production costs.

Winner3003 dry laser particle size analyzer is mainly used for any dry powder materials, especially particles that react chemically with water and change shape in liquid. The measuring range is 0.1-300 microns, and it is especially suitable for cement particle size testing.

Cement online particle size monitoring system

In the production of cement, particle size is one of the key parameters, which directly affects product quality. Traditionally, powder particle size testing uses manual sampling or mechanical sampling and manual laboratory testing. This method has many shortcomings: large sampling errors, partial representation of the overall process, and representativeness problems; not online, It is not real-time and the analysis data is seriously lagging; the analysis data has little significance in guiding the real-time production process and can only be a remedial measure.

Laser particle size testing instruments are increasingly used for production control due to their characteristics of speed, accuracy, repeatability, and convenience. With further requirements for production control, most cement manufacturers hope to connect particle size data with DCS systems to further achieve unattended working status. Therefore, online particle size analysis systems will become indispensable testing equipment in the cement industry.
