designing jaw crusher and rotary dryer equipment for the production process of acid-activated bentonite

Industrial clay bentonite consists of the nanostructure and nanoporous mineral montmorillonite. the most important applications of bentonite and its modified types include the absorption and release of salicylic acid (aspirin), the use of layered nano clays (ldh) in combination with biological materials, vitamins, drugs, and dna; the use in wound healing, disinfectant with 95% absorption of the coronavirus, and prevention and treatment of coronavirus. this study aims to design a jaw crusher and a rotary dryer for extracting valuable minerals, and utilizing the matlab software tool for modeling and design calculations. in developing the crusher, based on the guidelines of the references and considering the energy consumption of crushing, the average crushing ratio was selected as 3. regarding the dryer, the inlet air was at ambient (30°c and 1 bar), and the number of theoretical heat transfer units was assumed to be the average value suggested by the sources, i.e., 2. in the jaw crusher design, the crusher opening distance is calculated to be 6.22 inches. by performing the calculations, the most important results of the dryer are that the diameter and length of the rotary dryer are calculated to be 1.06 and 7.77 m, respectively.
