1、 Technical performance of the new dryer introduction of fly ash Drying technology is the production of fly ash, slag powder and other key technologies must be matched, I wet fly water for large proportion of small, fine grain size, and other notable features, the development of new and efficient dry
2、ing of fly ash machine, the device compared with other drying equipment, production capacity, continuous operation； structure is simple, easy to operate； less failure, low maintenance costs； for a wide range of fluid resistance is small, you can use it dry granule-like material, for adhesion of the
3、material that is also very beneficial to large； operating flexibility, allowing the production of greater fluctuations in the flow of product range, will not affect the quality of the product； cleaning easy. The equipment is now in Henan, Anhui and other enterprises put into use, and create consider
4、able economic benefits. New Fly Ash dryer - energy efficient, environmentally friendly. Chinas cement industry in recent years, a major breakthrough in comprehensive utilization of resources, waste cement industry consumptive use of solid waste in the country total more than 80%. By using less clink
5、er cement industry, more powder, the cement produced in low-capital technologies that can maximize the consumption of electric power, metallurgy, coal industry produced fly ash, slag, coal gangue and other industrial waste. Our process uses traditional cement clinker produced, mixed material mixing
6、mill, mill production is low, high energy consumption, waste slag and other materials used only as a hybrid, mixing amount of not more than 30%. Use of clinker, slag grinding process, respectively, the use of slag fine powder in the high state of good activity can be used as the main component of ce
7、ment characteristics, the preparation of blending of cement, admixture of 50% -60%, can substantially reduce the cement produced in the capital. Waste produced by the cement industry, based on a variety of waste powder admixture fair match to progress in concrete density, the formation of low densit
8、y, high density, low defect structure, much progress in concrete life. Chinas annual industrial waste slag produced 1.5 billion -16 billion tons of fly ash and gangue -6 reached 400 million tons, flooded areas in the department. Take advantage of cheap local coal ash, slag and other waste of resourc
9、es produced in low-capital high performance green cement, cement manufacturing is the transformation of the region an important way. Energy saving is a saving society, an important prerequisite for a harmonious society, but also cement the most effective way to profit growth. Energy efficiency is pr
10、ogress, but decided to advance the hub grinding efficiency is to reduce the moisture content of raw materials. Because fly ash, slag, etc. into the plant when the water is too large, is not conducive to ground, resulting in low yield milling system, full grinding and grinding, such as grinding paste
11、 deterioration in working conditions, must first dried before grinding into dehydration. Therefore, the fly ash produced dryer comprehensive utilization of fly ash with good development prospects. New Fly Ash dryer is produced in high energy-saving technology of fly ash, slag powder and other equipm
12、ent necessary for supporting the hub, in the promotion of energy efficiency of cement, representing centrifugal dewatering equipment, the old vertical dryer, in the design, energy efficiency and practical applications have great breakthrough. Old vertical dryer. Equipment from external burner, verti
13、cal dryer composed of host and environmental protection equipment, vertical assemble a brick inside the dryer, how abdominal group and the sliding hopper feed bowl set. Its working principle is: material handling equipment into the upper vertical dryer, set by its own gravity through the hopper, sli
14、de pots expected drop in sink. Burner to create heat, heat exchange through the vertical dryer, after discharge of environmental protection equipment. Course materials collection hopper and slip angle of the basin slowed down the speed of the material to extend the time for heat exchange materials,
15、but materials, materials in the collection hopper and slip sliding is the central basin discharge, the formation of the wind tunnel is in use a lot of heat Air filter materials, coupled with the continued cooling tube burner, thermal efficiency is only about 50%. The devices strengths are: small siz
16、e, less investment； disadvantage is that: the high consumption of coal, about 50% utilization of geothermal energy； high power consumption, power consumption 4kWh tons of dry material around； adaptability, and tend to occur the material, sealing； more stringent requirements on coal-fired heating； dr
17、ying quality can not control. Previous centrifugal dewatering machinery, equipment expensive, low capacity, dehydration rate of small, usually only one precipitation 10% - 20% of the remaining 15 water. The new full set of fly ash from the dryer three sectors: heating system, heat exchange system an
18、d to take the air dust removal system. Heating systems using hot stove technology sector, adequate heat, heat effect, structural simplicity； heat exchange system is the drying cylinder, the cylinder body lifting plate arranged in spiral staggered repeatedly Young Caesar materials, high efficiency he
19、at exchange ； ventilate the system will be equipped with dust filter, because the fly ash particle size, density, light, dry conditions in the negative pressure, easily flow away, leading to changes in fluid medium, and large dust gas water to prevent Cited air system into the atmosphere sucked out
20、of resources and environmental pollution extravagance, unified by the dust collecting. Fly ash drying machine will first be wet peeling machine conveyor were broken into horizontal, to prevent bulk material into the drying cylinder of the drying effect, has broken into the material and then drying d
21、rum, the cylinder body have much to copy board, arranged in spiral, driven by the rotating cylinder, keep the material copied toss board, Young Caesar, and the cylinder wall material again hitting crushing equipment, materials and the arguments raised air system full access to the incoming hot air,
22、heat exchange, evaporation of water to complete the drying, from the discharge port, the dust emitted by the dust removal equipment uniform collecting moisture. Sawdust dryer is how and product advantages of working class Sawdust dryer is how to work. Main works: wood chips into sawdust dryer drum rotary cylinder by the injection pipe and the joint action of boiling flow in the barrel of hot air full contact with the material to complete the drying, air-sawdust dryer, air drying is the so-called refers to the body like wet sawdust powder by screw conveyor
