Fly Ash Dryer Background Information: In the coal fired power plant,the fly ash (coal ash) hastwodischarging style: one is dry discharging style, the other is wet discharging style. In the rapidly developing cement industry, as the cement production mixing materials, the dryfly ashmarket israther considerable.The physicochemical properties of wet fly ash are basicly sameas the dry fly ash, butas thereis big moisture content (maximum is amount to 45%), the wet fly ash (coal ash) can not meet the requirements of cement production. As a result, the wet fly ash (coal ash) can only be piled up as waste, and occupy many storage place, even pollutes the environment. Then, how to dry the wet fly ash (coal ash) ? After years' research, Sunco Machinery developed one new type fly ash dryer. Ithas the advantages oflowenergy consumption, simple drying process, large drying capacity, etc. Fly ash dryer from Sunco Machinery can dry the wet fly ash (coal ash) from moisture content 45% to about 8% in large quantity directly. Fly Ash dryer Advantages: Low outlet temperature, long lifetime of dustcleaning system; Adopt new type lifting boards, and the output moisture content can be adjusted as customer's demand; High degree of automation, simple operation, stable working; Equipment investment needed is only1/6 of the importedequipments. Low investment, creat profit quickly; Adopt gear transimission,small transimission power needed; Compared withsingle pass rotarydrum dryer, it saves about50% floor area, 60% electricity consumption; Broad fuel choice: coal, diesel, natural gas, waste wood, etc. Fly Ash Dryer Specification: Model (m) Capacity (t/h) InputMoisture (%) OutputMoisture (%) MainMotorPower (kw) CoalCalorificValue (kcal/kg) Inlet Temperature () 1.5x14 10-15 273 8 15 5500 42010 1.8x14 15-20 273 8 18.5 5500 42010 2.0x20 20-25 273 8 18.5 5500 42010 2.2x20 25-30 273 8 22 5500 42010 2.4x20 30-35 273 8 30 5500 42010 2.6x22 35-40 273 8 30 5500 42010 3.0x24 45-50 273 8 37 5500 42010 3.2x26 50-55 273 8 45 5500 42010 Notice:Any change ofFly Ash Dryertechnical data shall not be advised additionally.

SHIVA TECHNO FAB is one of the leading manufacturer and suppliers of Industrial dryers such as Rotary dryer, Sand Dryer, Fly Ash dryer, minerals dryer, Coal Dryer, Biomass Dryer etc. due to business trends, public scrutiny, government regulation, water constraints, etc., coal power plants in India and overseas are endeavor to eliminate their ash ponds and replace them with dry solutions. If youre considering a transition from wet to dry ash handling, Shiva Techno fab will facilitate.
SHIVA TECHNO FAB has research and technical team , we manufacture Fly ash Drying Systems are custom-designed and made as pr customers requirements.. Our technical team considers all the parameters as like area specifications, foundation ,electricity and future fuel use, storage capability, location, etc.
Rotary Dryer Mainly Consist Of Shell (Drum), Inlet Hood, Outlet Hood, Girth Gear(En-9), Riding/tire Ring, Assembly, Burner/Hot Air Generator, Induced Draft Fan,Raw Product Inlet Hopper, Product Discharge, Flights, Air Seals, Rav, Cyclone Separator, Aluminum And Cerawool Claddings.
Feed Hopper Is Designed According To The Pond/fly Ash Properties . For Making Smooth Discharge We Are Providing Aeration System & Vibrator System For Free Flow Of Material. From Feed Hopper There Is One Screw Feeder And Weighing Hopper Which Is Commanded Through Plc & Hmi. So The Exact Feeding Should Be Done To The Dryer.
For The Handling Of Wet Fly Ash We Preferred Chevron Belt Conveyor To Deliver The Wet Fly Ash From Feeding Hopper To The Input Of Dryer. Our Belt Conveyor Consist With High Quality Structural Design And Instrumentation Devices Such As Zss, Belt Sway, Pull Cord And Etc. Our Belt Conveyor Is Fully Covered With Aluminium Or Pvc Sheet To Control The Dust.
Pulse Jet Bag Filter / Pulse Jet Hose Bag Type Filters Are Known As Conventional De-dusting Filters. Shiva Techno Fab Has Developed New Age De-dusting Designs For This Filters Which Gives Better Life Of Filter Bags, Lower Emission Levels, Lower Pressure Drops, Lower Power Consumption, Higher Air To Cloth Ratios With Better Performance Levels, Lower Floor Space Requirement. Shiva Techno Fab Supplies Customized Bag Filters On The Bases Of Application Requirement. These Pulse Jet Bag Filters Are Used Where Air-flows Are In Large Quantity, Temperatures Are Higher Than Ambient Or Material To Be Handled Is Difficult.

Flyash rotary dryer is also known as the three layers of drum dryer, three return cylinder dryer, on the basis of the single cylinder dryer, developed and manfactured,which is an industrial dryer on non-viscous, liquid material .At present three-cylinder dryer made by Dingli company,with mature technology, throughthe drying of the sand, fly ash, fly, mineral materials, slag and other material , the effect is very good.
The flyash are conveyed to silo by belt conveyor or bucket elevator ,and transport to the feed end by the feeder of silo .The inclination of the feeding pipeline should be exceed the natural inclination of materials ,so that to facilite sand flowing into the flyash dryer smoothly .The rotating cylinder of the dryer is slighly inclined to the horizon .To feed the material from the higher end and the heat carrier enter from the lower end ,such produce adverse contact between them .sometimes,they can be fed to the cylinder together .As the cylinder running,the sand carried to the lower side by the gravity.In the process of moving forward ,the wet raw material being roasted by the heat directly or indirectly to make the raw material to dry quickly, the final products discharge out by belt conveyor or screw conveyor..There is shoveling plate installed in the flyash dryer dryer with function of shoveling the materials up and down,to enlarge the contact area between airflow and materials and to enhance the efficiency and make the material running quickly.The heat carrier is hot air,the flue gas etc.After the dryer process,It need cyclone dust collector to catch the items in the airflow.You should use bag type or wet-type dust collector and afterward discharge the waste gas,if you intend to further reduce the dust load of the exhaust .

As a result of industry trends, public scrutiny, government regulation, water constraints, etc., coal power plants domestically and internationallyare striving to eliminate their ash ponds and replace them with dry solutions. For those considering a transition from wet to dry ash handling, Vulcan Drying Systems can help.
Vulcan Drying Systems' Fly Ash Dryers are custom-designed and manufactured around the desired solids tonnage and the moisture content of the customer's individual project. Our technical team considers all the parameters: available space, budget, current and future fuel use, storage capacity, location, generation rate, routing, and aftermarket choices, such as marketing and resale.
Typically, drying systems include a rotary dryer consisting of a drum with a burner. Fly ash is fed into the rotary dryer, then discharged to a transfer conveyor for sorting and separation. The vapor from the process is pulled through a cyclone to eliminate fine dust; a high-temperature, high-yield baghouse removes fine particulates from the vapor stream.
The resulting dry fly ash is easier to store and transport, and road construction and concrete industries have increased the demand for this material. The sale of fly ash for concrete production is potentially an excellent ancillary profit source for your plant.Get in Touch with Mechanic
