Reduce the consumption of bentonite pellets Practice
Given in Table 4, run through the mill of the mixture of particle size before and after use to track testing, the result in general increase the scope of the next 200 mesh only 6-8 percentage points, but its not difficult to find comprehensive analysis of the role, Mill Run is not only able to refine the mixture, more importantly,[link widoczny dla zalogowanych], in the refining process can be carried over mixture and mix on, grinding effect, it can be changed to some extent, mixed materials, grain size, increasing The specific surface area and change the morphology of materials to increase contact surface between the material particles to improve the hydrophilic material to increase the binding capacity between the material particles. 3 to strengthen the production process control, optimizing process control, enhanced process management 3.1 strengthen production management, reduce the ingredients error of 1) the implementation of raw material ingredients for 30 minutes to run the system disk once, while the control electronic scale data, to ensure stable feeding. 2) to strengthen inspection. Timely resolution of identified problems of measurement, ingredients to minimize errors. Such measuring instruments on a regular basis for check 3) standard operation. Close attention to the raw material of water, raw water if it is found abnormal, timely coordination with the previous procedure, to ensure stable moisture. Reasonable adjustment to the quantity, try to keep with the amount of stability. Same time changes in the raw material ingredients and the water back to the drying position, advance to facilitate drying control, stability, raw materials, pellet water. 32 fair use. Eliminate waste in the course of transmission of bentonite in the conveyor belt installed on the mixing device, for each feed opening is sealed, to prevent falling during transport span of dust caused by waste, table 4 with the comparison between before and after use of bentonite Mill Run pellet consumption state kiln finished the ball off the strength of anti-F project k # t finished strong utilization factor of time / balls degrees Bull / sieving index% balls after use before using 46.52z7894l322388.62 25.68q. 755925fI15.1732 Technology Information SOlENCE & TECHNOLOGYINFORMATION engineering technology can improve the operating environment. 3.3 good quality bentonite, stability,[link widoczny dla zalogowanych], quality and in strict accordance with quality standards of bentonite on the implementation of the batch into the bentonite plant sample analysis, ensuring the quality of bentonite to make the ball with the requirements of quality inspection failure bentonite is not compliance, then promptly notify the supplier manufacturers improve quality, strict quality control. 3.4 reasonable material storage, sorting carefully control the use of raw materials into the J of a management situation based on the quality of raw materials, water conditions were stacked in different reasonable, rational in the production process with the use of storage material, making sure to meet global demand. 4 Relying on technological progress, technological improvements to enhance skills 4.1, 1) drying equipment improvements. Jane on the drying be replaced within the lifting plate and effectively prevent drying simple plot material, improve the mixing effect, making the water more stable dry material, drying the same time increasing the height of the chimney of the original height of 4m, increasing the drying cylinder airflow rate and improve the drying effect. 2) regular screening roll gap adjustment, based on actual production experience, will screen the ball roll by the 8mm gap adjusted to 6mE. At the same time the ball rolls in the original screen based on the number of installations increased 12 to improve the screening effect of pellet and pellet quality, and improve the roasting process layer of breathable material, improve pellet quality. 4.2 training. Operator job skills training to seriously organize, improve skills,[link widoczny dla zalogowanych], while enabling operators to reduce the awareness of the importance of bentonite. 5 Effect of Fuyun pellets through practice, in 2008 aimed at reducing consumption of bentonite achieved significant results, bentonite consumption situation in Table 3. Table 5 shows that consumption of bentonite in 2008 21.9Ikg / t, with consumption 25.68kg/tJfl ~ 2007 bentonite ratio was decreased N4.6%, while raw material iron powder grade in 2008 reduction of 0.56 percentage points in the case of the finished grade of total iron ore pellets decreased only 0.46%, In contrast, by reducing the bentonite, the actual grade of the finished pellets increased by 0.1%. 6 Conclusion Fuyun bentonite pellet quality through optimization, to strengthen the production process control, and stability of the production processes,[link widoczny dla zalogowanych], relying on technological progress,[link widoczny dla zalogowanych], strengthen skills training, bentonite consumption reduction 3.77kg / t, reducing the rate reached 14.68 % a year savings bentonite 3883.1t, direct economic benefits can be 104.8437 million yuan, while for all the iron grade of pellets increased by 0.1%, increase profit 1,545,000 yuan.
