Diatomite Grinding Machine and Processing Line

Diatomite has a wide application. The raw diatomite materials can be used as fillers through crushing, screening, grinding and classifying.

 Introduction of Diatomite

Diatomite is a kind of biogenic siliceous sediment, which is mainly composed of the ancient remains of diatoms. SiO2 content of diatomite is usually more than 80%, the most content can reach to 94%. Diatomaceous mineral compositions are mainly opal and its variants, followed by clay minerals, such as water mica, kaolinite and mineral debris. Mineral debrisincludes quartz, feldspar, biotitic, and organic matter. Diatomite color is white, pale, gray and grayish brown, etc. There are with the physical properties of delicate, loose, light, porous, strong water absorption and permeability. Diatomite is mainly distributed in China, the U.S., Denmark, and France, the Soviet Union, Romania and other countries.

Applications of Diatomite

Diatomite is usually used as insulation materials, filter materials, fillers, abrasive materials, silicate materials, bleaching agents and diatomaceous earth filter aid, the catalyst carrier in industrial. It is also widely used in diatom mud, paint, interior and exterior paint, lacquer and polyester alkyd paints and other coating systems, especially suitable for architectural coatings production. Using it in coatings and paints can balance the surface gloss of the coating, increase the abrasion resistance and scratch resistance, dehumidification, odor, but also purify the air, soundproofing, waterproofing and thermal insulation, and good permeability.

Diatomite Processing Line

Because diatomite has some unique properties, such as: porosity, low density, high surface area, relatively incompressible and chemical stability, the original soil after crushing, sorting, calcining, grading, dedoping and other machining processes can change its particle size distribution and surface properties to reach a variety ofindustrial requirements of paints and coatings additives, etc.

In the diatomite processing line, we usually need jaw crusher, impact crusher and grinding mill, and some auxiliary equipment, such as vibrating feeder, belt conveyor and vibrating screen to increase the processing line’ degree of automation and output.

First of all, send the raw diatomite materials into the jaw crusher evenly and continuously by vibrating feeder for primary crushing. And then, transport the crushed diatomite to impact crusher for secondary crushing by belt conveyor. After that, send the medium crushed diatomite materials to vibrating screen for separating. After separation, the products which meet the requirement will be transported to the diatomite grinding mill for grinding, while the products which don’t meet the requirement will be returned to the previous impact crusher for re-crushing. Throughout grinding, send the diatomite powder with the proper size as final products. In this way, the whole diatomite powder processing line completes a closed circuit crushing, grinding and separating system.

Diatomite Grinding Machine

As for diatomite grinding mill, customers can choose the different kinds according to different production requirements, such as vertical mill, ball mill, trapezium mill, and so on. All of them our company and provide. And all of them are designed by our experienced engineers based on many years’ research. All of them are made by high quality materials, so it is the stable features and short downtime.

Among a variety of diatomite grinding machines, I have to introduce our LM vertical grinding mill to you at there. It is the equipment which integrates crushing, drying, grinding and grading conveyor all together. And compared with other traditional roller mills, the compact LM Vertical Grinding Mill has the space-saving design, reducing the civil construction costs. It has a wide applications, and it is widely used for grinding non-flammable and non-explosive materials under 9.3(the Mohs hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, slag, cement clinker, zircon sand, fly ash, coal, etc. And used it to process diatomite powder has unmatchable features. If you want to get high quality diatomite powder, LM vertical roller mill is your best choice, because it is with high classifying capacity and good final products quality.
