There are several ways gangue comprehensive utilization: ① coal and pyrite recovery: through a simple process, from coal gangue washed well chosen, by screening to choose the low-quality coal, but picked pyrite. ── shaker or pyrite recovery process from the plane with the jig coal preparation, wash mixed coal and coal. Recovery of coal can be used for power boiler fuel, can be used for washing gangue materials, pyrite can be used for chemical raw materials. ② for power generation: mainly used to wash and wash coal gangue co-firing power. China has been washed and washed coal gangue mixture (heat about 2,000 kcal per kg) boiling furnace combustion for power generation. Slag to produce slag and slag cement bricks. Japan has more than 10 seats this plant; the mixture of coal and waste rock with general heat per kilogram for 3500 kcal; insufficient firepower with heavy oil combustion. The Federal Republic of Germany and the Netherlands to own power plants and coal preparation plant built together to take advantage of the coal slime and gangue power generation. ③ manufacture of building materials: bricks instead of clay as a raw material, can be less fertile dig. When the brick, use of coal gangue itself combustible gangue grinder, you can save coal. Now the network is well developed, the three of us to advertise our company is also high gangue grinder through the network, of course, not just us, and now more and more businesses are coming publicity through the network, convenient for customers, but also facilitate us. It is precisely because there is no face to face gangue grinder manufacturers, all the various manufacturers in order to attract customers, the price war is inevitable, but in our customers, there is such a phenomenon, big scary price level differences, the lowest for this phenomenon Coal mill price, we analyze a bit. A part of the manufacturers to cheap temptation customers to sign a contract, make a fuss when the contract was signed, so that you can hike professional gangue grinder manufacturers, and customers must buy, because they do not buy it, would not be able to normal production This is a relatively common fraudulent means. 2, there are some manufacturers are cutting corners to attract customers through lower costs, the price will be much lower, so, there is a price advantage. Basically the price gap is reflected in both the inside, but not so three high mechanical integrity of our business, not fraud, more than Coal mill, another two-stage crusher, shale crusher, etc., all in accordance with the drawings for production, will not cut corners, not cheap temptation customers.
