Abstract

PROCEDIMIENTO PARA LA REGULACION AUTOMATICA DE INSTALACIONES DE TRATAMIENTO DE ARENA DE FUNDICION.CONSISTE EN PREFIJAR UN VALOR NORMAL PARA LA COMPRESIBILIDAD Y PARA LA HUMEDAD, MEDIR EL VALOR REAL DE LA COMPRENSIBILIDAD, MODIFICAR LA HUMEDAD HASTA SU VALOR NOMINAL, VOLVER A MEDIR LA COMPRENSIBILIDAD, Y LA DIFERENCIA ENTRE AMBOS VALORES SE UTILIZAN PARA AJUSTAR UNA RECTA. LA PRIMERA MEDIDA SE HACE AL PRINCIPIO DEL MEZCLADO Y LA SEGUNDA AL FINAL DEL MISMO PROCESO.
