Diatomaceous earth is a kind of biogenic siliceous sedimentary rock with the characteristics of fine, loose, light weight, porous, water absorption and strong permeability.
Diatomite has long been known and used by people. With the development of deep processing technology of non-metallic minerals in my country in recent years, diatomite is used as a filter aid, adsorbent, catalyst carrier, functional filler, abrasive, water treatment agent, asphalt Modifiers (fillers), etc., are widely used in light industry, food, chemical, building materials, petroleum, medicine, high-grade highway construction and other fields.
Natural high-purity diatomite is rare, so diatomite used in industry generally needs to be processed to meet the needs of the application field.
The application of diatomaceous earth in material fillers is second only to filter aids. It has a series of excellent characteristics such as light weight, softness, porousness, sound insulation, heat resistance, acid resistance, large specific surface area and stable chemical properties. A functional filler widely used in the field.
Particle size is one of the main characteristics of diatomite fillers. Diatomite fillers for different purposes require different particle sizes. The size of the filler particle size has a great impact on product performance. For example, in pesticide powders, the smaller the particle size of diatomaceous earth, the greater the energy required for dispersion during dispensing, the worse the fluidity, and the lower the forming processability, but the roughness and strength of the product are improved; On the contrary, diatomaceous earth with large particle size has better dispersibility and fluidity, but the surface roughness of the product is poor. In the plastics and rubber industries, fillers with coarse particle sizes are particularly prone to precipitate and reduce the strength of products.
As the most professional powder equipment manufacturer in China, Shanghai Shibang Group provides the best quality LM series fine powder mill products and supporting solutions for diatomite deep processing enterprises. The fineness of the finished product can be adjusted freely according to user needs to meet different users Processing requirements for the fineness interval.
