STF Sand Fly Ash Dryer, For Building Construction, Construction, Feature : Refractory

structure of rotary dryer (rotary drum dryer): rotary dryer mainly consist of rotary drum, inlet hole, discharging hole, ring, gear, carrier roller, transimission assy, air duct pipe, induced draft fan, hot air furnace, chimney, cyclone dust separator, etc.
performace features of rotary dryer (rotary drum dryer):

• energy saving: the consumption of coal and electric of shiva techno fab’s rotary dryer can be lower 8% to 16% than the normal rotary dryers, with the production ratio higher than 10% to 15%;
• environment friendly: the special design hot air furnace can supply the clean hot air for the rotary dryer, and there is little dust and noise during working process;
• compact structure, easy maintenance and operation, low invest cost;
• broad fuel option:  the fuel can be waste wood, biomass fuel, rice husk, natural gas, diesel,  electricity, etc.
• long usage lifetime: daily the user only need to add some grease on the transmission parts such as gear.

working principle of rotary dryer (rotary drum dryer):

• the hot air furnace supply the clean hot air inside the rotary dryer(rotary drum dryer). 
• the feeder machine sends the wet mateiral inside the rotary dryer(rotary drum dryer). 
• when the rotary dryer(rotary drum dryer) is rotating, the lifting plates inside the rotary dryer (rotary drum dryer)mix the wet material and hot air together sufficiently so that the wet material can be dried effectively by the hot air. The moisture of the wet material is evaporated into water vapour.
• the dried materials are discharged through the discharging hole as the product. 
• on the end of the rotary dryer (rotary drum dryer),there is one high pressure induced draft fan which suck out the water vapour, and then the water vapour goes into the cyclone dust separator. 
• in the cyclone dust separator, the dust mixed with the steam is separated from the water vapour, and falls down and goes out of the bottom discharging hole of the cyclone dust separator. The water vapour finally goes into the atmosphere by the chimney directly.
