the roleof the calciner in producing soda ash

The Role of the Rotary Calciner in Soda Ash Production. The two aforementioned processes rely on the rotary calciner to produce the purified soda ash. Calciners are comprised of a large, rotating cylinder (aka the drum), through which process gas is passed, allowing it to directly contact the material to cause the intended reaction

The calcination starts between 800°C and 900°C and the operational solid temperature usually reaches 1000–1200°C. The calcination temperature is dependent on the partial pressure of carbon dioxide in the kiln. A simplified illustration of a rotary kiln for lime production is presented in Figure 1. The upper setup shows the conventional air‐fired process used as a reference case in this work

modeling for the calcination process of industry rotary

Rotary kiln is important equipment in heavy industries and its calcination process is the key impact to the product quality. Due to the difficulty in obtaining the accurate algebraic model of the calcination process, an intelligent modeling method based on ANFIS and clustering algorithms is studied. In the model, ANFIS is employed as the core structure, and aiming to improve both its performance in reduced computation …

calcination processdevelopment & calcining equipment

Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type. It is also common to follow the calcination process with a rotary cooler. This efficiently cools the material after it has been calcined, so it can move on to transportation or storage

rotary kilns| sciencedirect

The main function of the rotary kiln in the minerals and materials industry is to convert raw materials (ore) into useful product materials. Most or all of the kiln processes involve some chemical or physical reactions that will occur at economically rapid rates, if at all, only at high temperatures
