Technical performance of the new dryer introduction of fly ashDrying 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 drying 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 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 considerable 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 clinker 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 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 cement 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 density, 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 resources 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 progress, 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 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 equipment 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, vertical 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, slide 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, 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 size, 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; drying 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 and 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 heat 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 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 drum, 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, 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 to continuously add drying tube, the delivery of high-speed hot air and dispersed the. Galileo Heavy sawdust dryer is designed for sawdust, wood chips, small pieces of wood, veneer, wood drying wet materials and professional design and manufacturing, with a drying speed, yield, remarkable energy saving, low maintenance features . Wet sawdust dryer to evaporate the moisture in the material, powder or granular dry products by the process, mainly by the air heater, feeder, air drying tube, cyclone, fan and other components. Characteristics of chicken manure dryer, we will introduce you to here. Galileo mechanical scientific research, production, marketing as a whole, market-oriented enterprises, rely on technological innovation and management innovation to promote the development, production sand dryer mainly based manufacturers. How to choose the right drum dryer The so-called rotary drum dryer, also known as rotary drum dryer. Its wide range of applications, mainly used in building materials, metallurgy, chemical and cement industries, drying of the material mainly of limestone slag, coal ash, slag, clay and so on. It consists of rotary body, lifting plate, gear, support equipment and seals and other components. And has a reasonable structure, well-made, high output, low energy consumption and easy operation. Meanwhile, the rotary drum dryer can also be used in fertilizer production, grain drying and fertilizer certain humidity, the aircraft also has a high thermal efficiency, uniform drying, cleaning materials, the number of small, suitable and convenient maintenance. So the selection of drum drying machine? Choose the right drum dryer which method? Heres a brief look at how to choose the right drum dryer. We want to know, usually drum dryer direct heat transfer medium is dry flue gas, where we will be divided into a downstream or upstream drying drying for two: first, the first to know what is along countercurrent flow drying and drying. The so-called downstream drying is its combustion chamber and wet feed materials in the same side, the heat flow direction and the direction of movement of materials is the same, the wet material from the feed end to discharge end of the transfer talk, hot air is from feed-side induced draft fan in the blower and the discharge side to go down the role of outflows in the process flow of wet material with hot air heating and drying; the so-called counter-flow is drying wet material from the feed end into the dryer, combustion chamber in the discharge end, in the process, the material and the hot air is doing the reverse movement, the wet material in motion the process of being dried by heat. Second, in the purchase, the specific way we choose to be dry and the dry material from the final request. But we should know that the initial drying driving force downstream drying larger, later with the material temperature, the drying medium temperature will be decreased, this comparison applies to the final water content (ie dried) less demanding materials. Countercurrent drying in the drying process, due to more uniform drying driving force, it is appropriate to be dry and dry material is strictly demanded. Dryer operating processes and precautions when using Dryer understanding of people know that, proficiency in the operation of the dryer process and use precautions is important, because it is about whether the normal use of the dryer and the process can be used to avoid a lot of unnecessary trouble . Heres a brief look at the dryer operating procedures and precautions in use. First, the operation of the dryer process, we mainly of five ways. The first is in operation, before opening the door of the dryer feed, the dehydration of the fabric tube into the turn, and then feed the door closed and locked; second is at the right time, the regular rotation button to the desired location; the third is in front of the preparatory work to do, start button, dryer drying, drum and exhaust fan to begin the work of the normal drying; fourth in the drying process, should always pay attention to the fabric to be dried so that accidents can take immediate measures; fifth is in the baking process, machine failure, should be immediately stopped, in time to find out the reasons for failure, and in a timely manner excluded. Second, when the note on the use of mainly explained from three aspects: first, before starting to pay attention to the dryer, make sure to feed the door closed and locked, take the fabric to ensure that the machine stops running, to avoid accidents ; The second is to regularly clean the filter on the suction fan, keep it clean; the third is to use the device in accordance with relevant provisions, not to violate the relevant national standards. Vacuum drying how to improve profit margins? Although the resin dryer is usually referred to as auxiliary equipment, but the decision of its type selection there may be a plastics processing, play a leading role in business strategy. This is in Belgium (the whole family), it is such, is a global cross-industry manufacturers, business focus involving electronic and electrical (E & E) equipment, components for injection molding. By abandoning the traditional hot air dryers in favor of the principle based on a new type of vacuum drying equipment (Figure 1), completed its Hasselt in Belgium (Hasselt) plant simplifies the injection molding process to obtain a substantial savings and improve product quality. As with other electronic and electrical (E & E) equipment supplier, as the three strategic challenges facing: 1) intense price competition caused by the supplier relentless pressure to cut costs, improve production efficiency; 2) customers on product quality and balance the demanding requirements; 3) the long-term energy costs will be high expectations. Vacuum Drying of the most obvious benefits related to the third challenge: with similar specifications, hot air dryer (Figure 2) compared to completely dry resin in the vacuum dryer can save 80% of the energy. However, due to the completion of the original, while only one-sixth of the time, the use of vacuum dryer will have the opportunity to significantly improve production efficiency. The short term, this can be started on Monday morning ahead of manufacturers in the production of cold start time; in the long run, it can provide a more streamlined operational convenience to concentrate. Finally, Vacuum Dryer provide shorter residence time and higher efficiency to reduce drying defects and lower reject rate. Used in the factory in Hasselt 40 molding machines, 26 table is used for injection molding polyamide 6.6 material to be made into models of AA and AAA batteries small security cover. The use of 12 hot air dryer to dry 26 resin molding machine. By using the three US-Kui? LPTM vacuum dryer replaced (fourth sets new LPD vacuum dryer for emergency standby), according to the Technical Manager, Mr. Rudi Vermeulen stated that achieved the following results: Energy cost savings. 92% reduction of energy consumption, saving 15,700 euros. The corresponding cost savings estimate does not include the power sector, Mr. Vermeulen the additional peak imposed a fine of 5,000 euros, not including the estimated Mr Vermeulen great to exclude from the factory for the production of heat hot air drying machine electricity consumed by air-conditioning energy savings. Production longer. Cold start by reducing the time Monday morning, received an additional 192 hours per year at full capacity production time. According to Mr. Vermeulen rough estimate, assuming that sales levels will be sufficient to maintain the plant at full capacity, this new production capacity can bring an extra 57,600 euros per year could be the amount of sales of products. Streamlining and automation. While hot air drying machine 12 in any one able to meet not more than 2 sets of injection molding machines for production capacity requirements, vacuum
