Ministry of Industry and Information Technology of the People's Republic of China "On the Cement Industry Energy Saving Guidance" recognizes that the cement industry energy savings achieved great progress, significantly reduced overall energy consumption per ton of cement, but the unit energy consumption compared with the international advanced level, there are still gaps. Vertical mill, grinding roller and other high efficiency grinding technology and frequency conversion technology have not been fully applied.
In order to better help the cement companies improve mill efficiency and reduce grinding energy, organized by the China Cement Net "2014 7th International Grinding Summit" is held on May 22 in Nanjing.
As a top China cement grinding system supplier, Xinxiang Great Wall Machinery be the first one to call upon “Embrace the World without Ball Mill”. Accordingly, the Raw material Vertical Roller Mill (VRM), Cement VRM, Blast Furnace Slag VRM, Nickel VRM, Steel Slag VRM, we produced and sell, are widely used in most of the large-scale cement plant.
Amount which, A single spark, the Blast Furnace Slag VRM, start a prairie fire in the recent Chinese Market.
To blend the GGBFS in the cement, cement activity are improved and so does its concrete fluidity and density. In the 7th summit, one of the cement plant from Jiangsu province have a share, through its living example, of making a great profit by best use of the GGBFS. Some of the useful data shared with you.
For a cement plant with the capacity of 300000 tons per year, GGBFS additives are put in 65000 tons and the steel slag powder is 25000 tons. These costs are at about RMB 120 Yuan per ton for totally 6 item costing.
1. Labor cost: ￥15 per ton
2. Maintenance cost: ￥3.5 per ton
3. Electric charge: ￥46 per ton (including drying costs)
4. Coal drying costs: ￥6 per ton(it can be saved, if you can use the waste heat from steel plant)
5. Material: ￥5
6. Freight:￥50
The cement selling price is ￥300 per ton. The profit can be made at ￥180 per ton. It is said the cement plant can make 4.5 million profits annually even only with the steel slag powder additives. This shows that the GGBFS production line is extremely busy in China now and Great Wall Machinery becomes a new trend leader again in this big moment.
