Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA ELEVAR EL PESO A GRANEL DE PERBORATO SODICO MONOHIDRATADO EN FORMA DE PARTICULAS QUE SE OBTIENE A TRAVES DE LA DESHIDRATACION DE PERBORATO SODICO TETRAHIDRATADO. LA COMPACTACION CONOCIDA DEL PERBORATO SODICO MONOHIDRATADO EN UN CILINDRO-PRENSA CON CILINDROS ESTRUCTURADOS Y CON LA TRITURACION SUBSIGUIENTE DE LA DESFOLIACION DA LUGAR A ELEVADOS PROBLEMAS SEGUN LAS REGLAS TECNICAS. LOS PROBLEMAS SE SUBSANAN CON ARREGLO A LA INVENCION , YA QUE SE PROPONE LA COMPACTACION EN UNA ETAPA DEL PRECOMPRESOR Y SE MANTIENE LA TEMPERATURA DE LA SUPERFICIE DEL CILINDRO Y DE LA PARTE DE LOS PRECOMPRESORES QUE ESTAN EN CONTACTO CON EL PRODUCTO POR DEBAJO DE 20 C.
