Diatomite, also known as diatomaceous earth, is a type of silica rock, mainly composed of SiO2 with small amounts of Al2O3, Fe2O3, CaO, MgO, and organic matter. It is a biogenic silica sedimentary rock primarily made up of ancient diatom remains. The color of diatomite is typically white, gray, or grayish-white, and it has the characteristics of good strength, strong permeability, lightweight, sun protection, and high-temperature resistance. Diatomite is mainly distributed in China, the United States, Denmark, France, Romania, and other countries.
Due to the high impurity and mixed content of other materials after sedimentation, diatomite cannot be directly used as an industrial raw material. It usually needs to be processed by calcination. To fully utilize the calcination effect of diatomite, we have conducted in-depth research on its structure, hardness, mineral composition, and other characteristics. We have also developed highly targeted and professional equipment for diatomite calcination, namely the diatomite rotary kiln, which has significant performance advantages and affordable prices.
highlights of our diatomite rotary kiln
The unit product heat consumption of the diatomite rotary kiln is about 5000kj/kg, which is 15-30% lower than that of the countercurrent single-tube mechanized mixing vertical kiln.
less heat loss
The diatomite rotary kiln has a reliable combination of scale sealing at both ends of the rotary kiln, with a leak rate of less than 10%, using composite refractory materials to reduce radiation heat loss.
The kiln head of the diatomaceous earth rotary kiln adopts a shell-type seal, and the kiln tail is equipped with an axial contact sealing device to ensure the reliability of the seal.
longer service life
The equipment has a long kiln life, high operating rate, stable operation, high heat transfer efficiency, and low heat consumption.
diatomite rotary kiln applications
The diatomite rotary kiln is developed based on diatomaceous materials and belongs to the category of building materials equipment. It can be used for dry and wet production operations of different diatomaceous materials. The diatomite processed by the rotary kiln can be applied in various industries.
- The calcined diatomite is an ideal raw material for particle preparations and pesticide powders. It makes the overall production of the formulation more stable, maintains the efficacy for a longer time, and has certain fertilizer effects. It has a strong adsorption capacity for various nitrogen, phosphorus, and potassium in compound fertilizers and has a certain slow-release effect in soil, which is beneficial to the overall growth of crops.
- After high-temperature calcination, diatomite can also be used to produce high-quality silica cement, which improves the flow and plasticity of the overall equipment in the cement concrete production process and enhances the wear resistance and corrosion resistance of the entire cement diatomite.
- It can also be applied to waterproofing rolls and high-asphalt content fillers to improve the anti-slip, wear resistance, and compression resistance properties of asphalt, significantly extending the overall service life.
- In insulation materials, the high-temperature calcined diatomite has high overall porosity and excellent properties such as insulation, heat insulation, sound insulation, and corrosion resistance, making it widely used.

Diatomite rotary kiln working principle
high-temperature combustion of organic matter in diatomite to make the internal pores and micropores permeable and breathable, increase the particle gap of finished diatomite, improve the permeability of the entire diatomite, and reduce impurities. Our company has further improved and researched the technology and energy-saving of new calcined diatomite production rotary kiln, and after crushing and screening the entire original diatomite mine, mixed with water and stirred, then granulated to make wet balls of different specifications of 1.5-20mm, which are then transported to a special diatomite rotary calcination kiln for overall improvement. The calcination of finished diatomite is increased by more than twice, and it completely meets the standard for the use of overall diatomite.
