7 basic process flows of ultrafine grinding
The mechanical ultrafine grinding process generally refers to the grinding and classification process for preparing particle size distribution d97≤10μm, which is divided into dry method and wet method. The ultra-fine grinding unit operation (i.e. one-stage ultra-fine grinding) currently used in industry has the following process flows:
Opening process
Generally, airflow mills such…
Ultra-fine grinding of non-metallic minerals
Non-metallic mines, metal mines, and fuel mines are called the three pillars of the materials industry. The use of non-metallic minerals depends on the degree of deep processing, including ultra-fine grinding, ultra-fine grade, fine purification and surface modification, among which effective ultra-fine grinding is the prerequisite and guarantee for various deep processing. The ideal ultra-fine…
Grinding machine fault treatment and daily maintenance
The grinding of materials is an indispensable process in the production of products in many industries (such as metallurgy, mining, building materials, chemicals, ceramics, etc.). Due to the difference in the physical properties and structure of the materials, the selection of the grinder should also be analyzed in detail.
There are many grinding equipments on the market. Choosing a suitable…
Features of ultra-fine grinding equipment
After the material becomes finer, many new properties will appear. Pigments, medicines, catalysts, fine ceramics, abrasives, magnetic materials, solid lubricants, metal powders and many other aspects require ultra-fine powders. Ultra-fine powder requires extremely fine particle size, uniform particle size distribution, and high product purity, so it is very important to select appropriate…
The processing and application of talc
The color change of talc is mainly caused by impurities. The more impurities, the darker the color. The pure ones are white, and the impurities are slightly yellow, pink, light green, light brown and other colors. The dense block has a shell-like fracture, the relative density is 2.58-2.83, and it is rich in slippery, with a glassy luster, the cleavage surface is pearly luster, and the cleavage…
Air Classifying Mill
Air Classifier Mill: The material is uniformly sent into the grinding chamber by the feeding system, and is strongly impacted by the high-speed rotating grinding disc. At the same time, it is subjected to the centrifugal force to collide with the crushing ring gear, and is subjected to various comprehensive forces such as shearing, friction, and collision. The material is ground, and…
Congratulate! Another foreign industry leader and ALPA reach cooperation
In recent years, with the continuous expansion of sales territory, the superfine grinding machine developed and produced by Shandong ALPA Powder Technology Co., Ltd. has been sold all over the world, gradually expanding the share and influence of ALPA in the international market. This time, ALPA once again reached cooperation with well-known enterprises in the battery material industry of South…
