 Of 1: demand shocks. From the demand side, the Japanese earthquake that short-term production decline in the steel industry, especially coal driven metallurgical coal demand. As second only to China's second largest steel producer, steel production in Japan in 2010 110 million tons in 2010, imports of coking coal is about 5800 tons, the equivalent of 200 million tons of coking coal trade in the world 30% is bound to affect the international coking coal price. Similarly, for thermal coal, the above analysis logic is valid.

Of 2: post-disaster reconstruction. We believe that large-scale reconstruction will be held after 3 months, when iron and steel, nonferrous metal products, demand will significantly increase production capacity of iron and steel industry began to recover, the demand for metallurgical coal, tend to rise.

Of 3: other factors. From time to consider, we note that the Japanese earthquake has the potential to backward extension of the negotiating agenda of coking coal, may affect the price increases expected. From the monetary considerations, Japan and New Zealand monetary policy or monetary policy after the disaster the same loose, including the coal industry is expected to enhance the related industries, including the valuation.

Of 3: The world need to reflect. Nuclear power plant in Fukushima area of ​​disclosure, or the fun world of new energy, coal and other traditional energy security may make governments re-evaluate long-term needs or will rise.

Wind swept coal mill use and application

Wind swept style is a major cement plant equipment for drying and grinding coal. Equipment, mainly by the feed device, main bearings, rotating parts, gear, Tao  devices, high-voltage starting equipment and lubrication system. Feeding equipment from raw materials loaded into the feed mill, the hot air from the inlet pipe into the mill, with the mill of the rotating cylinder, coal and hot air for heat exchange in the mill, coal mill to be crushed and ground, in the Coal is ground at the same time, powder is the hot air through the mill, through a feeding device with a mill.

Coal mill is broken and ground into a pulverized coal crusher machine, it is important pulverized coal boiler auxiliary equipment. Coal grinding process is broken and the surface area of ​​coal has been growing process. Coal in the coal grinding mill was made of coal, mainly through the crush, break and crush three ways.

Classification of coal mill Working parts of coal by grinding speed can be divided into low-speed mill, pulverizers and high-speed mill. The main purpose of coal mill Coal mill is the material to be broken, and then to smash the key equipment. Coal mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other mineral production industries of all kinds of ores and other grind-able materials can be dry or wet powder grinding.
