According to reports, mill pulverizing system is the main power plant equipment required for the power plant boiler pulverized coal grinding, also widely used in metallurgy, building materials, coal, chemical and other industries milling system. The plant self-developed series ZGM medium speed roller mill, has more than 2,300 sets of production for three consecutive years with an annual output more than 400 units, achieved annual sales of 20 billion yuan, becoming the largest annual world-class mill coal production base, there have been 350 exported to 15 countries such as Japan, South Korea, India, Indonesia, Turkey, Russia, Belarus, Albania, Kenya and Chile.

 

In energy conservation, low-carbon economy in the background, the plant continued to adhere to independent innovation, based on the introduction of technology digestion and absorption, through technical research, has independently developed the successful "ZGM-Ⅰ, Ⅱ, Ⅲ type speed roller style mill "series. By increasing the disc speed, loading force, and optimize the structure design, so that output than the original basic significantly increased. Press ratio, increase the speed of new product tranches of 12% -33%, 20% -60% load force, a substantial increase in grinding efficiency, grinding coal saving 0.3 to 1.0 kWh / t. At the same time, using a combination of static and dynamic separators new technologies, coal fineness finer and more uniform, more complete combustion, reducing harmful emissions of nitrogen oxides and the like.

The mill series adopts the international advanced hydraulic variable load, rotating nozzle, planetary reducer, rotary separator, new wear-resistant materials, such as a number of new technologies to improve energy saving, long life wear new pulverizers, Quick Start, coal adaptability, and overall performance. Output ranges from 16.3 tons / hour to 223.8 tons / hour, to meet the different needs of users. Achieve motor manufacturing, reducer, mill body (including wear parts) stop supporting the production at the factory, effectively ensure product quality. The new products have achieved 278 sets of market performance, which has 130 stations in operation, export 68 units.

Experts believe that the series of products through the industrial test and obtain engineering applications, according to the test report on actual projects to verify the mill's output, respectively, than the base model of 12%, 24%, 33%. New products in the domestic market has been widely used and produced good economic and social benefits. Identification of the Committee agreed that the product technical indicators have reached the advanced level, agreed to adopt the product identification.
