What is The Application of Diatomite and Diatomite Grinding Mill?

Date:2023-08-29 13:36:11    From:    Click:
Diatomite, also known as kieselguhr, is a distinctive sedimentary rock of significant importance across various industries. It primarily consists of the fossilized remains of microscopic aquatic plants called diatoms, which flourished in freshwater and marine environments millions of years ago. The distribution of diatomaceous earth spans several countries including China, the United States, Japan, Denmark, France, Romania and others. Each region possesses unique geological formations and characteristics that contribute to the quality and properties of the diatomaceous earth found there.
 
From a chemical perspective, diatomaceous earth mainly comprises silicon dioxide (SiO2), represented by SiO2·nH2O. This composition grants it exceptional absorbent qualities and renders it highly valuable for diverse applications. The mineral composition predominantly encompasses opal and its variants. Due to its porous nature and high silica content, diatomaceous earth finds extensive utilization in filtration systems for water purification purposes as its intricate structure effectively entraps impurities such as bacteria, algae or debris particles from liquids or gases passing through it.
 

About Diatomite

 

 
 
Diatomite, typically light yellow or gray in color, is a soft and porous material widely utilized in various industries as insulation materials, filter media, fillers, abrasives, water glass raw materials, decolorizing agents, diatomite filter aids and catalyst carriers. The unique microporous structure of natural diatomite can be observed under a microscope and is responsible for its distinctive physical and chemical properties.

Raw Ore Property

Diatomite typically contains a small amount of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 and organic matter. SiO2 usually accounts for more than 80%, reaching up to 94%. The iron oxide content in high-quality diatomite generally ranges from 1% to 1.5%, while the alumina content ranges from 3% to 6%. The mineral composition of diatomite primarily consists of opal and its varieties, followed by clay minerals such as hydromica and kaolinite. Mineral detritus includes quartz, feldspar, biotite and organic matter. Organic content varies from trace amounts to over 30%. Diatomite exhibits colors ranging from white to grayish white or gray with light grayish brown tones. It possesses properties such as delicacy, looseness, lightweightness porosity water absorption and strong permeability. Most of the silica in diatomite is amorphous with soluble silicic acid content ranging from 50% to 80% in the base material. Amorphous SiO2 crystallizes when heated between temperatures of 800°C and 1000°C while reducing the soluble silicic acid content in the base material to around 20-30%.
 

Physical Property

The density of diatomite ranges from 1.9 to 2.3 g/cm3, with a bulk density ranging from 0.34 to 0.65 g/cm3. It possesses a specific surface area of 40-65㎡/g and a pore volume of 0.45-0.98 cm³/g, enabling it to absorb water up to two to four times its own volume. Additionally, it exhibits a unique porous structure that can be observed under an electron microscope and has a melting point between 1650℃ and 1750 ℃.
 

Application of Diatomite

 
 

For Soil Improvement

The pH value of the substance is neutral, indicating that it is neither acidic nor alkaline. This characteristic makes it non-toxic and safe to use in various applications.
 
When used in agricultural machinery pipelines, this substance demonstrates excellent mixing uniformity without causing blockages. This ensures smooth flow throughout the system and prevents any disruptions during operations. In soil applications, this substance plays a crucial role in enhancing moisture retention within the soil matrix. By retaining moisture effectively, it helps plants access water for longer periods between irrigation cycles. Additionally, by improving soil structure through increased porosity and aggregation of particles, this substance promotes better root development and nutrient uptake by plants. Moreover, when applied alongside fertilizers or nutrients in agriculture practices, this substance extends their efficacy by preventing leaching or runoff into groundwater sources. It acts as a carrier for these essential elements while slowly releasing them over time for plant utilization.
 
 
 

For Paper Making

It boasts excellent extensibility, high impact strength, tensile strength, tear strength, light and soft internal abrasion resistance, good compression strength, and other high-quality features. In the paper industry, it is used for office paper, industrial paper, and other types of paper. Diatomite has advantages such as a lightweight and fine body with fineness ranging from 120 mesh to 1200 mesh. Adding diatomite can make the paper smooth and lightweight while improving its strength. It also reduces expansion caused by humidity changes and can adjust the burning rate in cigarette papers without any toxic side effects. In filter papers, it improves filtrate clarification and speeds up filtration.
 
 
 

For Animal Feed

The fineness of diatomaceous earth feed ranges from 120 mesh to 1200 mesh, exhibiting a light and delicate texture. It finds application in the feed industry for various animals including pigs, chickens, ducks, geese, fish, birds, and aquatic species. Diatomaceous earth feed offers numerous advantages: it possesses a neutral pH value and is non-toxic; the unique pore structure of diatomite mineral powder renders it lightweight and soft; it exhibits high porosity and strong adsorption capabilities. Upon addition to feed, it forms a light and softly colored mixture that disperses evenly without separation. It aids digestion in livestock and poultry by absorbing bacteria from their gastrointestinal tracts while also promoting physical fitness through the strengthening of tendons and bones. In fish ponds, diatomaceous earth enhances water quality by providing clarity with good permeability which ultimately leads to increased survival rates of aquatic products.
