Jinyuan sintering plant process design configuration of the cold griddle

Take 1.03; H - so in the 1 / 2 fine sieve effect coefficient, taking 1} M - mesh layers Department is committed to, take 1; s - screen factor, taking 0.85; c - mesh form factor, taking 1.2; - sinter bulk density, take 1.7t / m. . The generation of each parameter were calculated on the type of secondary cold screen design of a screening Sec Area: paragraph. 230 - Lili Lili Shiva surface of a 7.2 (m) Sec 230 and the side surface Lai Lai ● A 6.4 (m.) Therefore, the design of the secondary screening area of the cold screen should be Az + A2 A A, ie 7.2 +6.4-13.6 (m.). Through the above calculation, it is easy to see the second screen of cold mineral process design to meet the requirements of 230t / h this target, we must ensure the effective screening area of 13.6m. The shaker is concerned, the effective surface area of the larger screen, the unit surface of the mesh sieve effect on the more chance of mineral particles through the sieve the more, so the screen surface of the unit higher productivity and screening efficiency. Shaker is the effective area of the sieve screen surface area and the ratio of the area. The effective area of the sieve is generally 50 to 80 (based on data provided by the manufacturer) to ensure the strength of sieve, sieve designers by 5O to determine the effective area, the preliminary design of the secondary cold screen LZS258S the geometric area of the distribution of l: The shaker screen surface area of the whole: 21.25in. z. These include; a screen for the entire screen surface plot Ha 13.75m, Sec screen the entire screen surface area 6.25in. , Blind area of 1.25m. This can get: a screening of the effective area of 6.857m. , Sec effective screen area of 3-125m. . The effective area of the shaker limits the cold ore particles opportunities through the sieve, which sieve screening unit yield and efficiency of process design is difficult to achieve the required targets. To illustrate this point I Qu. Blind plate shaker set in the feeding zone is not only false Jing, holding debates block, and the sieve screen surface is divided into two sub-office should be re-set the Blind. Thus, in the second screen of the cold area of 21.25m in the screen surface should also include 2.5ITI. Segmented blind area, so some, two stage screening area to be reduced accordingly. MINE DESIGN AND CONSTRUCTION 26 1998 3 in the production practice, the factors that affect the screening operations of addition to the above operating conditions, but also have a lot of the factors, this is no longer listed in the above two factors on analysis, in general, the first class in the process design factors are not randomly change, but the second choice in the design of the sieve elements must be carefully considered. 5 Conclusion In summary, in order to ensure that the whole system of ore sintering plant cold two or three cold mine sieve screening efficiency in productivity and process design and production processes to meet the requirements, so I figure in the design stage of construction on whole system, two or three cold mine design selection screen to modify the original withdrawal of the preliminary design options LZS2585, LZS2060 two cold modify the design for the mine shaker LZS3090, LZS2575 two cold mine shaker. Practice has proved that in the whole sintering process design, if you do the whole process of sintering cold mine reasonable choice, the right to determine the screening process parameters and equipment selection. Qualified to get the desired product size from Korea on the sintering process, equipment and environmental technology to ensure that the benefits of play. More importantly, due to the success of a sintering cold mine whole, can enhance the smelting furnace to improve blast furnace production. Reduce the blast furnace coke, sinter whole play really technical and economic effects of the first of the Received Date 19980126 Huoxiu Hua, senior engineer of the Design Institute of copper, 117,000 square Benxi City, Liaoning Province Mountain Park Road, No. s1. Path: ① grain refinement (reduced d); ② At the same time reduce the increase in activity and A} ③ the number of dislocations N (or..) Of course, the surface can be increased or the elastic modulus reached this goal, but the two non-structural sensitive properties, the effect was significantly better than the first three. Using statistical theory of dislocation mechanism and derived statistical distribution function of micro-cracks, find the most probable crack propagation, which is derived fracture strength, range of deformation before fracture, the crack extension force, fracture toughness, critical crack length and and other physical quantities as a function of both a theoretical exercise to discuss the value of the actual work is also instructive.
