Mineral soil refers to a wide range of natural mineral materials, including clay, kaolin, bentonite, bauxite and ball clay. Rich in silicates and alumina, it is a basic raw material widely used in industries like ceramics, building materials, chemicals, metallurgy and papermaking. The quality of mineral soil directly affects the performance of end products.
Why Mineral Soil Needs Drying？
Freshly mined mineral soil usually has a high moisture content (15%-25%). Without drying, it will cause big troubles in subsequent processing:The wet soil easily clumps and blocks production machines, slowing down the whole workflow.High moisture ruins the quality of mineral soil—for example, it reduces the whiteness and purity of non-metallic mineral soil, and accelerates the oxidation of metallic mineral soil.Transporting and storing wet mineral soil costs more money, because you are essentially paying for the extra weight of water.By drying mineral soil to an ideal moisture level (1%-5%), you can ensure smooth processing (like shaping, firing and smelting), improve product quality and add more value to your raw materials. Drying is a key step to make the most of mineral soil resources.
How to Dry Mineral Soil Efficiently？
The most popular method today uses a rotary drum drying system, and the process is straightforward:
1.Pre-screening: First, remove large impurities from wet mineral soil to reduce the load on the dryer.
2.Feeding & mixing: Send the screened soil into a tilted rotating drum. Inside the drum, special lifting plates repeatedly pick up and scatter the soil, turning it into a uniform "curtain" of material.
3.Heat drying: Hot air (powered by natural gas, biomass or other fuels) flows through the drum. It contacts the scattered soil fully, and the step-by-step temperature control (from 600-800℃ at the drum inlet to 200℃ at the outlet) quickly evaporates the moisture.
4.Smart humidity control: The system is equipped with humidity sensors and exhaust devices. It releases moist air in real time to avoid re-moistening the soil, and recycles waste heat to cut energy use.
Drying is the vital link between mineral soil mining and industrial application. Our mineral soil dryer solves the problems of low efficiency, high energy consumption and unstable quality in traditional drying processes. It not only helps make full use of mineral resources, but also drives the green and low-carbon transformation of the industry. As global manufacturers demand higher raw material quality, this dryer will play a core role in more industrial fields.
