What factors may affect the measurement results of powder laser particle size analyzer?
Particle size analyzers from different manufacturers and models often have different designs. They have different optical designs. For example, linear and folded paths, pre/post-Fourier transform, and laser size. They also have Fourier lenses of different sizes and focal lengths. And different numbers and distributions of detectors. Plus, different specs for sensitivity, noise, and optical parts. […]
The difference between marble and limestone in preparing heavy calcium powder
The appearance of things hides the inner differences. As the saying goes in polymer physics, structure determines performance. In-depth, a structure’s chemical properties determine its outer properties. These ores go from ore to powder. This involves breaking the ground ore. Then, grinding it using methods like dry and wet grinding and equipment like rollers or […]
23 Uses of Kaolin in Various Industries
(1) Ceramic industry The ceramic industry was the first to use kaolin. It also uses the most kaolin. The general amount is 20% to 30% of the formula. Kaolin’s role in ceramics is to add Al2O3. This can improve its stability and sintering strength. (2) Rubber Adding kaolin to the rubber mixture can improve its […]
What is the difference between effective density, true density and apparent density?
True Density: The theoretical density of powder materials. The volume used in the calculation is the volume of particles. It excludes open and closed pores. Effective density (floating density): The density value that can be effectively utilized by powder materials. The volume used is the volume of particles. It includes closed pores. But, it does […]
Selection principle of bag filter filtration speed
Selecting the filter speed of bag dust collector is key. It should be based on the type of smoke or dust. It should consider where it will be used. It should also consider dust size, thickness, and gas temperature. Also, it should consider moisture, dust levels, and filter materials. Select a low value when the […]
Light calcium carbonate production and surface modification technology and equipment
Limestone is used to make light calcium carbonate. It’s heated to make lime (calcium oxide) and carbon dioxide. Then, water is added to make lime milk (calcium hydroxide). Carbon dioxide is then added to make calcium carbonate. It’s then dried and crushed. Light calcium carbonate production technology and equipment In the industry, light calcium carbonate […]
What does the carbon black dispersion tester test?
The tester measures and analyzes the carbon black particle distribution. It measures them in liquids or solids. This equipment is often used in industrial production. It is especially key for developing industries like plastics, rubber, inks, and coatings. It is also key for food. The carbon black dispersion tester works by measuring dispersion. It does […]
Heavy calcium and light calcium, 10 essential differences
Now, the market has mainly heavy, light, activated, and nano calcium carbonate. Heavy and light are the most used. Many users often have questions. They are all calcium carbonate. So, what is the difference between heavy and light forms? Production method We make heavy calcium carbonate by crushing natural minerals. These include calcite, limestone, chalk, […]
Technology for preparing decorative sintered bricks using iron tailings and coal gangue
Tailings are considered “waste” discharged by mining enterprises under certain technical conditions. They refer to tailings. These are discharged after ores are crushed and beneficiated to extract useful components. These are mine wastes that can’t be sorted further at present. Various tailings are generally piled up in tailings ponds near mining mines. The mining time […]
