Product Description Light Material Drying SystemMaterial DescriptionLight material means the powder or small particle material with the density of about 0.4-0.6t/m3, such as sawdust, bamboo shavings, rice husk, xylose, wood shavings, wood blocks, etc. Light material is generally with high water content, such as, commonly the saturated water content of the sawdust is 45-50%, and some of them can reach 60%; THE light material is relatively loose, the use of air transport will not plug the pipeline. System IntroductionIn recent years, with the increasing of environmental resources, the comprehensive utilization of biomass energy has become more and more important to us. Due to the high moisture content of the sawdust, broken wood, which leads the incomplete combustion, resulting in that the spark burns the dust bag at the back of the drying plant, which not only causes the excessive emissions, but also it's with high cost to change the dust bag. In the process of producing wood products and biomass fuels with high burning combustion value, wood chips and broken dregs are required to do the drying process. Process FlowAfter being fed into the hopper, under the function of gravity the raw material will fall onto the belt conveyor laid under the bottom of the hopper, and then which will be conveyed onto the screening machine, the massive, strip and other irregular material will be separated out after screening, and uniform particles will be conveyed to the feeding end of the dryer (The single cylinder or three cylinder dryer will be chosen as per the service condition) by the belt conveyor under the screening machine. The feeding end of the dryer is connected with heat source and the discharging end is linked with pulse air pipes. The fire wall will be setted up in the hot blast stove in order to guarantee the safety of the drying process, to eliminate the phenomenon of material burning in the dryer, and the heat passing through pipe will be installed between the hot blast stove and the dryer as the section of heat buffer. The material will brought into the diameter-transformed pulse pipe after being dried and the dehydration for the first time inside of the dryer, which will be in a suspended boiling form at the large diameter of the pulse pipe, and then it will be quickly dried after contacting with the exhausted heat wind from dryer. And the material will be driven out of the pulse pipe by strong winds and moved into the first stage cyclone collector when its water content reaches the design requirement, and 80% of dried material will be collected, and then get into the second stage cyclone collector after passing through the induced draft fan to collect the left material. The second stage cyclone collector can be replaced by the bag type dust collector.Technical ParametersModelCylinder diameter(mm)Cylinder length(mm)Cylinder volume(m3)Cylinder rotary speed (r/min)Power(kW)Weight(t)VS0.6×5.860058001.71-832.9VS0.8×8800800041-843.5VS1×101000100007.91-85.56.8VS1.2×5.8120058006.81-65.56.7VS1.2×81200800091-65.58.5VS1.2×10120010000111-67.510.7VS1.2×11.8120011800131-67.512.3VS1.5×815008000141-51114.8VS1.5×1015001000017.71-51116VS1.5×11.8150011800211-51517.5VS1.5×1515001500026.51-51519.2VS1.8×1018001000025.51-51518.1VS1.8×11.8180011800301-518.520.7VS1.8×15180015000381-518.526.3VS1.8×1818001800045.81-52231.2VS2×11.8200011800371-418.528.2 VS2×15200015000471-42233.2 VS2×1820001800056.51-42239.7 VS2×2020002000062.81-42244.9 VS2.2×11.822001180044.81-42230.5VS2.2×15220015000531-43036.2VS2.2×18220018000681-43043.3VS2.2×20220020000761-43048.8VS2.4×15240015000681-43043.7VS2.4×18240018000811-43753VS2.4×20240020000911-43760.5VS2.4×23.62400236001091-44569.8VS2.8×182800180001111-34562VS2.8×202800200001231-35565VS2.8×23.62800236001481-35570VS2.8×282800280001721-37575VS3×20300020000141-35575VS3×23.63000236001701-37585VS3×283000280001981-39091VS3.2×23.63200236001931-390112VS3.2×323200320002571-3110129VS3.6×363600360003661-3132164VS3.8×363800360004081-3160187VS4×364000360004521-3160195
