Abstract
CODELCO, división Chuquicamata, actualmente dispone de tres áreas de concentración, denominadas A0, A1 y A2. Parte de las instalaciones de esta planta corresponden a la remolienda, donde actualmente catorce molinos procesan el concentrado obtenido de la flotación. Dichas instalaciones presentan problemas de bajo rendimiento metalúrgico y baja confiabilidad operacional. Por estas razones se solicita el reemplazo de los actuales molinos de repaso por tres molinos verticales a instalar en un nuevo edificio, proyecto que se realizara en la modalidad EPC (Engineering, Procurement and Construction).El presente trabajo realiza una parte de la ingeniería de detalles asociada a la especialidad mecánica-piping a partir de lo indicado en la ingeniería básica. Para lograr este cometido se revisan y validan los diversos documentos, tales como, criterios de diseño, memorias de cálculo, planos entre otros.El desarrollo de cálculo hidráulico se realiza una vez terminado y validado el balance de masa y los flujos los cual son determinados por la disciplina de procesos.Validados los criterios de diseño y definidos los flujos, se inicia el desarrollo del cálculo de líneas de piping del proceso de manera conjunta con la selección de las bombas.De forma paralela se desarrolla el cálculo y diseño de cajones, los cuales se fabrican de acero calidad ASTM A-36, con revestimiento interior de goma natural, para evitar el desgaste prematuro por el efecto abrasivo de la pulpa de concentrado de cobre.
CODELCO division Chuquicamata, currently has three areas of concentration, named A0, A1 and A2. Part of the facilities of this plant correspond to the remolishing, where at present fourteen mills process the concentrate obtained from the flotation. These facilities present problems of low metallurgical performance and low operational reliability. For these reasons, it is requested the replacement of the current mills by three vertical mills to be installed in a new building, a project that materializes in the EPC modality (Engineering, Procurement and Construction).In the present work it performs a part of the engineering of details associated to the mechanical-piping specialty from the indicated in the basic engineering. In order to achieve this, various documents are reviewed and validated, such as design criteria, calculation reports, plans and others.The development of hydraulic calculation is done once finished and validated the mass balance and flows, which is determined by the discipline of processes.Once the design criteria have been validated and the flows have been defined, the development calculation of piping process lines is started in conjunction with the selection of the pumps.In parallel, the calculation and design of drawers are developed, which are made of ASTM A36 grade steel, with natural rubber inner lining, to prevent premature wear due to the abrasive effect of the copper concentrate pulp.
