What is a Rotary Kiln?
A rotary kiln is a cylindrical vessel that rotates slowly on its axis, allowing materials to be processed or heated in a controlled environment. It consists of a long, inclined tube made of steel or refractory material, with different zones for various processes.
What is a Rotary Kiln?
In the feed zone, raw materials are introduced into the kiln and brought up to temperature gradually. As they move towards the discharge end, they undergo chemical reactions and physical changes. The combustion chamber is where fuel is burned to provide heat for the process.
The main advantage of using a rotary kiln is its ability to handle high temperatures and facilitate complex thermal reactions. It can be used for calcination, drying, roasting, pyrolysis, or sintering of various materials such as ores, minerals, cement clinker, and coal gangue.
Rotary kilns are widely used in industries like cement production, lime manufacturing, alumina production from bauxite ore, and even waste incineration. They offer excellent control over temperature profiles and residence time within the kiln.
Overall,a rotary kiln plays an essential role in many industrial processes due to its versatility and efficiency in handling high-temperature applications
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
