SSC800 new tooth grade crusher in the booming coal mine Coal Preparation Plant


Output size / mm ≤ 70mm (rigid adjustable) limit on the rate /% 5 ~ l5 been crushed rate /% ≤ 20 Power / kW2 × 110 power supply 380V/50Hz3 test analysis after six months of continuous production use, June 2,vibram five fingers outlet, 2008 on the SSC800 grade crusher technical performance stand-alone technology for continuous sampling inspection. Table l shows the SSC800 grade materials into the crusher feed size distribution. Table 1SSC8OO grade materials into the crusher feed size distribution% (1) crushing efficiency. SSC800 grade crusher crushing efficiency of 57.5%, while the original use of the hammer crusher crushing efficiency is only 13.66%, broken four times more efficient. (2) fine-grained increments. SSC800 crusher fine grading increment of only 3.53%, while the original use of the hammer crusher fine increments of 13.56%, fine-grained incremental decrease of 10 percentage points, greatly improving the small lump yield. (3) particle size characteristics. Figure 1 shows the SSC800 crusher size grading curve. From the grain size curve can be seen, SSC800 grade crusher can accurately control the particle size, and have lower over-grinding, with the crushing, screening of double effect. Size / mm Figure 1SSC800 crusher size grading curve 51 No. 4 August 2008 coal technology NO. 4Aug. 2008 Wen Luo Number :1001-3571 (2008) 04-0052-03SKT jig selected points in the application of thermal coal Li;,mulberry bags uk, Ruggie (Coal Research Institute Tangshan, Hebei Tangshan 063012) Abstract: The the coal washing characteristics and requirements, by comparing several commonly used coal washing process, that the jig in the sorting process coal areas, and describes the characteristics of SKT jig and application of that The jig is a series of wide grain size ideal for thermal coal sorting equipment. Keywords: Jigging; coal separation; wide grain size; technical characteristics; applications WORDS: TD942.1 Document code: A present,herve leger sale, the supply of steam coal market, the average 27% ash, and the U.S. coal-fired power coal ash in the 9,23% of requirements. China's coal in 2006 was selected 35.7%, according to In recent years, China is gradually increased the proportion of coal was selected, in terms relative to the coking coal preparation plant, coal preparation plant with low prices, product variety, requires a more flexible system of washing and so on. So. Product quality to meet the requirements under the premise of coal preparation plant construction should be reflected in investment, production and processing costs low. One of several commonly used coal separation process currently used coal sorting methods are: dry separation, lump coal gangue row moving sieve jig, jigging, heavy media row of lump coal gangue shallow groove, moving lump sieve jig Refuse Dumping + end heavy medium cyclone coal, lump coal heavy medium light tank discharge end of the coal gangue + heavy medium cyclone. A variety of process characteristics shown in Table 1. Table l commonly used method of sorting through the coal can be seen in Table 1: dry separation process a small amount of sorting accuracy is low,Oakley sunglasses sale, suitable for roughing; moving sieve jig processing costs low, allowing large size, sorting accuracy than high, but only two products suitable for lump row Received date :2008 -07-20 Author: Li Yue (1974) Download, River jE Province, Xian county, engineers, in 1998 graduated from Liaoning Technical University, Mechanical design and manufacturing expertise. Now at the Institute of Coal Research Institute Tangshan coal preparation equipment in, C,, is mainly engaged in jigging coal preparation technology and equipment research and design of coal preparation plant. Tel: (0315) 7759471.4 conclusion SSC800 new tooth grade crusher run in the booming coal mine coal preparation plant has been running smoothly, there has never been operational failure, high security and reliability, broken to good effect, too crushed gangue rate than S2; shallow groove sorting machine processing a large amount of sorting accuracy, but the investment and higher production costs, particularly those that require sub-elect three products, you need the Lord, wash both systems, more complex . Used for large coal preparation plant. Coal is not graded on the jig,Beats By Dre Headphones, wide grain size and the block, at the end of coal sorting can be applied only to hard coal sorting accuracy is poor. Coal is usually easy to coal, and therefore more suitable for sorting using jigging technology. According to low, and the rigid particle size adjustable, easy to equipment repair and maintenance, high degree of automation, intelligent control system and improve the overload protection system, a significant economic and social benefits, with good promotional value.
