Application of laser particle size analyzer in refractory material production

Refractory materials are a type of inorganic non-metallic materials with a refractoriness of not less than 1580°C. It is widely used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, military industry, etc. It is an essential basic material to ensure the production operation and technological development of the above-mentioned industries. It plays an irreplaceable and important role in the development of high-temperature industrial production.

For the performance of refractory materials, the selection of particle size is extremely important. The correct choice of particle size directly affects the quality of refractory materials. The introduction of micro-powder and ultra-fine powder technology greatly increases the density of refractory products, promotes the firing of samples, increases the strength of products, and improves the durability and erosion resistance of refractory materials. For indefinite refractory materials, especially for low cement, ultra-low cement castables and self-flowing castables, ultrafine powder plays a certain role as a binder and has a water-reducing effect. The particle size and distribution of micro powder also have a great influence on the water addition amount and fluidity of the sample as well as the performance of the material.

Therefore, how to control the granularity has always been a concern of people. The Winner2000ZD wet laser particle size analyzer produced by Jinan Winner Company adopts an all-round scattered light detection system and a high-sensitivity ring photo detector to further improve the testing accuracy. The dispersion system integrates mechanical stirring, ultrasonic dispersion and built-in circulation, which completely solves the problem of large particle deposition in pipelines. The original unconstrained free fitting software technology ensures the authenticity and accuracy of the test results. Using self-developed intelligent control technology, it can realize automatic centering of the optical path and perform one-click testing.

Winner2000ZD places the micro powder to be measured into a sample cell and uses a He-Ne laser to measure the particle size of the particles in the liquid through liquid dispersion (usually water). When the particles flow through the sample window, scattered light is generated. The detector behind the sample window receives the scattered light signal and determines the energy level of the light through analysis. The particle size and distribution were calculated using MIE theory inversion. The testing range can reach 0.1-300μm.

Using the Winner2000ZD wet laser particle size analyzer for particle size control has extremely obvious advantages over traditional particle size control methods (such as screening methods). 1) Small amount of sample is required. 2) The test speed is fast, and the test can generally be completed within two minutes. 3) The particle size testing range is wide and the resolution is strong. 4) Able to give a variety of information, such as D10, D50, D90 and other data.

In refractory material manufacturing enterprises, Winner2000ZD wet laser particle size analyzer has been widely used.
