It is necessary to utilize special techniques of separating submicron-size particles from other micron-size particles such as hydrocyclone and liquid-liquid separating. In this experimental work, separation of TiO2 and Al(OH)3 artificial mixture was investigated. Separation of submicron TiO2 particles from micron Al(OH)3 particles was carried out using a column bed filled with plastic fiber tub...

This paper demonstrates an application of Artificial Neural Network {ANN) for determination of undedlow and ovedlo w densities of Hydrocyclone separators. The discussions are extended and further results are presented for the prediction of particle size distributions in the underilow and ovedlow streams. The fit the experimental results against the predicted results are illustrated and statisti...

coarse product in the underflow. It is well known that injecting water in the conical part of the cyclone reduces the fine particle fraction in the underflow. This paper presents a mathematical model that simulates the water injection in the conical component. The model accounts for the fluid flow and the particle motion. Particle interaction, due to hindered settling caused by increased densit...

Modeling for the ball mill grinding process is still an imperative but difficult problem for the optimal control of mineral processing industry. Due to the integrated complexities of grinding process (strong nonlinearity, unknown mechanisms, multivariable, time varying parameters, etc.), a hybrid intelligent dynamic model is presented in this paper, which includes a phenomenological ball mill g...
