Optimization of an abrasive attritioner for the production of sand type A

The mechanical modifications were designed to alter the operating parameters of an abrasive attritioner and optimize the purification process of silica sand. The characteristics and operation of the abrasive attritioner owned by the company Silice de Cartago S.R.L. (SICA S.R.L.), were studied. The physical composition and the properties of the mixture supplied to the attritioner and the silica sand were studied in the quality conditions defined by the company. Three tests were performed in the abrasive attritioner, varying the parameters established to look for optimization tendencies. The procedure for the tests realization, composed of eight stages: preparation, collection, atricion, washing, drying, cooling, magnetic separation and X-ray analysis was explained. Modifications to the current configuration of the attritioner were proposed to have a greater impact on the optimization of the purification process. The construction diagrams and lists of necessary materials were prepared for modifications chosen
