The Application Study Of Flexible Design Process Of Coal Preparation Plant Of Heng Yuan Coal And Electricity

Coal production management is a relatively extensive management areas of production, which is determined by production constraints and product quality requirements, however, especially with the coal business management thinking, organizational structure, equipment and technology, continuous development and innovation, coal production in the field of coal washing and processing should be innovative and improve in production methods and process. This article through flexible coal washing and processing studies to address and adapt to the underground production changes and changes in market demand situation.1. By analysis coal production uncertainty and the variability of market. Including the conditions of occurrence of coal seams and coal quality diversification analysis; The different seam mining conditions influence to the raw coal;such as the influence of the miningproduction ratio, the influence of the mining method; the influence of the transport promotion process; diversification of coal product structure in the post-separation. Through the reasonable analysis of changes in the needs of internal and external market demand to determine the structure of the product. Coal is a large commodities in bulk material, mainly by rail transport, The trading of coal products by transportation conditions influence. Companies often can not arrange wagon transporting.Thus, the shipment volume changes and loads a car timeliness also become the flexible production should be considered factor. Of course, the flexible design of the coal preparation plant is also limited by the investment, venues and processing fees.2. Some Issues need to be determined about coal preparation process.1) Coal preparation method determine, including raw coal particle size of upper limit and the lower limit determination, raw coal selected way:grouped classification determination, the determination of the main separation intermediate approach,2) Coal preparation process of structural design:Including the gravity flow structure of the sorting operation, structure of coal flotation process and slime water treatment process structure. 3) The coal preparation flexible process design, Including the prepare separation of flexible design, gravity separation of flexible process design, Flexible process design of the coarse slime recoveryand coal slurry treatment.4) Development of the coal preparation flexible process aided design system, Made a presentation on the operation of the system interface and functionality, for convenient and better flexible design.5) By choosing the scene of raw coal data,take the flexible design processto design, expand the coal preparation flexible process aided design system as a new-aided design tool.
