Rotary Kiln For Diatomite
Products Description
what is diatomite rotary kiln?
The Rotary Kiln for Diatomite is an industrial heat treatment equipment specifically used for the calcination, purifying and drying of diatomite. It eliminates impurities, moisture and other volatile components from diatomite using high-temperature rotary calcination, endowing it with higher chemical stability, heat resistance and absorbency. Because of their exceptional performance, quality that surpasses international requirements, and adaptable operating systems, rotary kiln for diatomite are extensively utilized in industries like fertilizers, cement, steel, aluminum, building and refractory materials.
What is diatomite ?
A type of siliceous rock, diatomite is found mostly in China, the US, Japan, Denmark, France, Romania, and other nations. The remnants of extinct diatoms make up the majority of this biogenic siliceous sedimentary rock. Opal and its variants make up its mineral composition, whereas SiO2 makes up the majority of its chemical composition. Following processing steps like crushing, sorting, calcination, air flow classification, and impurity removal, the original soil's particle size distribution and surface characteristics can be altered to satisfy a range of industrial needs, including coating and paint additives.
Product key features
Our rotary kiln for diatomite adopts a rotating cylinder structure, which can be heated evenly during the heating process. The high-temperature resistant inner lining material can better adapt to the characteristics of diatomite.
Our rotary kiln for diatomite adopts a PLC automatic temperature control system. During the diatomite calcination process, it can flexibly adjust multiple temperature zones to achieve precise temperature control and save labor.
Our rotary kiln for diatomite is equipped with a waste heat recovery system, which can reduce energy consumption. The adoption of a low heat loss design has greatly enhanced the calcination efficiency of diatomite.
The low-emission design of our rotary kiln for diatomite satisfies environmental protection regulations. It is more ecologically friendly when combined with a dust collection system because it drastically lowers emissions of pollutants.
Working principle of rotary kiln for diatomite
Our company has further improved and researched the process and structural design of the new rotary kiln for diatomite production. After crushing and screening the entire original diatomite mine, it is mixed and stirred with water and granulated to produce wet balls of various specifications ranging from 1.5 to 20mm. These are then transported to a dedicated diatomite rotary kiln for high-temperature calcination, where the calcination volume of the finished diatomite has more than doubled, fully meeting the overall diatomite usage standards.

Product applications
The rotary kiln for diatomite purifies diatomite through high-temperature calcination, significantly enhancing its performance and making it widely used in multiple industries
- The pesticide industry can use calcined diatomite. It is non-toxic, has a neutral pH, a light bulk density, strong adsorption, good suspension performance, and good mixing uniformity. It will not clog pipelines used by agricultural machinery. It can help retain moisture in the soil, soften the texture of the soil, extend the benefits of fertilizer and pesticides, and encourage crop development.
- Calcined diatomite can be used as an additive in cement. Adding 5% diatomite to cement production can enhance the strength ZMP, and the SiO2 in cement becomes more active, making it suitable for use as emergency cement.
- When used in building insulation materials, calcined diatomite can improve the goods' anti-aging, heat, and wear resistance qualities. For instance, ceramic items, floor tiles, thermal insulation bricks, roof insulation layers, and architectural materials that insulate against heat and sound.
- Calcined diatomite is light, soft, and has good internal abrasion resistance. It features excellent ductility, high impact strength and tensile strength. It can be applied in the papermaking industry to produce various types of paper such as office paper and industrial paper.
