Biofuels are first used in China

On November 10, 2015 at 9 o 'clock, the Hebei Bazhou 300000 t/a slag powder production line of CHAENG is formally put into production, as the EPC turnkey contractor, Related officials of CHAENG Participated in the opening ceremony, and offering warmest congratulations.

　　The biggest difference between this production line and the other 70 production line had made by CHAENG is the Biofuels has been used as the heat source, Biofuels are the product of the process of Organic waste harmless and resource recovery, all the living material of Biofuels can turn Into the earth's biological cycle, Even the released carbon dioxide will be absorbed by plants and participate in the cycle of earth again, achieve zero emissions, the indissolubility, Recyclability Is a kind of modern advanced production mode.

　　Top 5 advantage: Without the desulfurization, zero release, cyclic utilization, Storage and transportation is convenient, the energy ratio 1:1.1

　　In recent years, CHAENG Put special emphasis on innovation in environmental protection, in the Hebei Aosen 600000 t/a slag production line, blast furnace gas was used as heat source, its use save the cost of fuel, also taked advantage of waste gas of adjacent Steel Plant

　　End of October, the Hebei Bazhou slag powder production line’s pilot run, let we know CHAENG’s GRMS33.31 slag VRM has the characteristic of Stable running, low noise, specific surface area could reach 500㎡/kg, can fully meet the requirement of fine quality for mixing plant

　　It is understood, Hebei Bazhou slag powder factoy has built 2 slag poeder production line Until now, The annual output up to 600000 tons. Has sign a contract of the new 300000 t/a production with CHAENG at the end of march this year, the construction and production to begin at the beginning of April, finished at the end of November, With only seven months, CHAENG has finished the equipment manufacturing, installation, commissioning, Make the customer start production fast and easy

The prices for investment slag vertical mill production line how much money

As a cement substitute an equal amount of production is important - slag powder can significantly improve the overall performance of concrete and cement products, as well as a significant reduction in cement, concrete production costs, now as a new high performance cement and concrete admixtures are Applications in cement plants, grinding plants, steel mills, has formed a "investment who should benefit whoever" situation.

　　Great Wall Machinery can undertake an annual output of 20-150 tons of slag / slag / nickel slag / manganese slag powder production line project EPC general contracting services, until now, the Great Wall machinery has been successfully established in more than 100 slag vertical mill production lines outside China.

　　In addition, the Great Wall of China machinery industry has an annual output of 600,000 tons the first demonstration training base slag powder machine and industrial waste (slag, slag, nickel slag) R & D center, extensive industry experience and strong technical capability enables mechanical energy provided from the Great Wall scientific reports, raw materials testing, engineering design, equipment manufacturing, construction, installation, commissioning, staff training, production standards, one-stop "turnkey" service.

　　The slag line ROI display:

　　Xinxiang Great Wall Machinery 600,000 tons vertical roller mill production line, for example, the total investment of 50 million yuan, in April 2011 and put into production, it is already two years to recover all the investment cost of equipment, is currently in a state of pure profit. Specific costing, please refer to the following table:

　　Great Wall Machinery slag vertical mill resolve unique advantages:

      Slag vertical mill process

　　Slag piled up by a forklift reclaimer, feeding, conveyed by belt conveyor. In the delivery process, the slag material has received iron and sieved through a separator and a shaker, and then weighing equipment warehouse, hoist into the vertical mill grinding. After slag grinding by means of hot air stove provided, were selected by the powder separator, at the same time get dry. In line with the required fineness slag powder it was finally delivered to the precipitator to collect, after full bloom, the air delivery chute, hoist into the finished products in storage.

　　To ensure that customers throughout the project successfully conducted and completed, the Great Wall machinery pioneered the industry's first "Taiwan vertical mill, eight service" value-added solutions, from pre-project to the final production, the Great Wall machinery to provide full guidance.

 Features

　　Process introduction:

　　Qualified limestone (20 ~ 50 mm) are lifted by bucket elevator to top silo of preheater. There are two level indicators (up and down) controlling the feeding amount, then they are separated averagely into preheaters’ individual rooms. The limestone’s temperature rises to about 900℃ heated by kiln flue gas of 1150℃, about 30% of them are decomposed, and they come into the rotary kiln by hydraulic rod, where the limestone decomposed into CaO and CO2. The decomposed limestone are put into the cooler, where its temperatures drops to 100℃ and released. The hot air (600°C) will come to kiln after heat exchange, and mix with coal gas for mixture combustion. The exhaust gas is released by the blower into bag deduster through multi-pipe cooler, then into the chimney though exhaust blower.

　　The limestone from the cooler will be transported to the limestone final product silo through vibrating feeder, chain conveyer, bucket elevator, belt conveyer.

Great Wall can produce rotary kiln with diameter Φ1-Φ5m, which is widely used in metallurgy, steel, chemical, refractory, ceramsite, papermaking industries. The kiln supporting has rolling and sliding type and the drive can use DC or AC variable frequency control. It has various seal types for different working condition . Great Wall can also design and customize non-standard rotary kiln according to customer’s special requirements

 Features

　　Structure of rotary kiln

　　Rotary kiln is composed of shell, drive device, support and thrust roller, kiln lining, kiln inlet sealing, head hood and burning device etc.

　　Shell is the heated rotation part, which is welded by high quality carbon steel plate. It is mounted on supporting device through tyre. Mechanical or hydraulic thrust roller is equipped on supporting device. So it will control shell slide in axial direction. Driving device makes shell rotate through gear according to required revolving rate. Big size kiln has auxiliary drive to make shell rotate at low speed for kiln installation and maintenance request. In order to prevent cooling air into kiln and dust come out kiln, there is sealing device at kiln inlet and output end.

　　Working principle

　　Material will be feed into kiln tail through chute in gas chamber. As kiln shell is inclined and it rotates slightly, material will move along round shell and will also move along shaft direction from kiln tail to kiln head. Material will be processed through pre-heat, decompose, calcined and will be feed into cooler. Fuel will be given through gas or coal burner at kiln head and will be combusted in kiln. Heat will be transferred to material by fire radiate, hot air flow, kiln brick transfer. The heat will heat and calcine material enough and make it final product.

　　Application

　　Rotary Kiln is a kind of thermal equipment calcines lump, bulk and slurry materials. It is widely used in cement & construction, non-ferrous metals, lime, ferrous metals, refractory materials, industrial chemicals, paper making industries etc.

　　Features & Advantages
