For desulfurization process in thermal power plant, limestone is the desulfurizer, so limestone grinding is very important. Hongxing keeps remember that their consumers need high performance products and also they anticipate high efficiency, great profit and strong competitive power. Among industrial powder making equipment, for processing limestone, there is medium-speed grinder, super-fine pulverizer, water slag superfine grinder, barite superfine grinder, kaolin superfine grinder, superfine grinder mill, ultra-fine micro grinder mill, small superfine grinding machine, grinding mill equipment, powder making equipment, cement grinding machine, high-efficiency pulverizer, vertical grinding machine and other advanced technological grinding production line and complete grinding equipment. But for current desulfurization device, there is one big problem on desulfurizing installation. In vicious competition in price leads low equipment quality, so the operation rate of desulfurizing installation is less than 60%, and huge investment doesn't make air pollution go down.
Henan Hongxing Mining Machinery Co., Ltd., as the long cooperation of many power plants, cement plant and steel mills, spends long time on researching and innovating grinding machines and specializes in researching limestone grinding equipment. Hongxing launches unique and independent MTM overpressure trapezium grinding machine also called big size grinding machine. For the past, we mainly adopted several measures to control sulfur dioxide discharging in thermal power plant such as low-sulfur coal, closing small thermal power unit and installation of FGD plant in some thermal power plants.
Developed countries all over the world all value the problem of sulfur dioxide discharging in thermal power plant. At present, power plants in Japan have installed FGD plant, there are 90% units in Germany have installed it, and USA, Finland and other countries are trying the best to develop the desulfurization technology. Improved grinding machine adopts six grinder rolls to achieve large volume production to meet demands of all big size thermal power plants. Our desulfurization industry develops very fast: desulfurizing installation with 40 million kw set up in the end of year 2005, 70 million kw in the end of 2006, and till 250-300 million kw in the Eleventh Five-Year Plan period. The desulfurizing installation is equipped with all kinds of grinding mills, such as grinding machine, MTM medium-speed T grinder, XZM micro grinder, high pressure grinding machine, MCF coarse grinding machine, ball mill, LM vertical mill, MTW European mill, screening and cleaning equipment, vibrating screen, impeller sand washing machine, screw sand washer, mobile crushing station, complete set of equipment, stone production line, sand making production line, grinding production line, vibrating conveyor equipment, vibrating feeder, Raymond mill, trapezium mill, medium-speed mill, ultra-fine micro mill, coarse grinding machine, vertical mill, European mill, pulverizer, grinding mill equipment and other series of grinding mill equipment with big size, high efficiency, energy conservation and environmental protection. All make Honxing grinding mill equipment win consumers' reliability and applause.
Grinding mill equipment from Henan Hongxing is ideal equipment combining with crushing, drying, grinding, grading and conveying for grinding industry. Since the mid-70s of the last century, in USA desulfurization market takes up above 10 billion dollars per year, and even under the gradually mature desulfurization market, it takes up 6 – 8 billion dollars.
