We are offering sand dryers.
Rotary drier instruction :-
sand dryer is also known as rotary sand dryer. For the drying of sand , the rotary dryer is used widely, and usually it is single drum sand dryer and triple-pass drum sand dryer.
Rotary drier structure:-
drum, gear, ring, carrier roller, air pipe, high pressure draught fan, reducer machine, chimney, cyclone dust catcher, 50mm thickness heat insulating layer, feeder, electric control box, belt conveyor, etc.
Rotary drier working principle:-
firstly, use one belt conveyor or bucket elevator to send the wet silica sand into the drum of sand dryer.
On the inner wall of the cilinderdrum, there are many lifting plates which is welded according to one special methods. when the sand dryer drum is rotating, these lifting plates makes the sand up and down to mix with the hot air completely. Durng this process, the moisture is evaporated.
on the another side of the silica sand dryer, there is one high pressure draught fan which sucks out the steam, and then the steam goes into the cyclone dust separator.
In the cyclone dust separator, the dust inside the steam falls down and goes out through the discharging hole of the cyclone dust separator. The steam goes into atmosphere directly through the chimney which is connected to the cyclone dust separator.
Furnace for the sand dryer usually has two types. For the handling capacity below 30 th, our company's new design hot air furnace is very suitable. We have produced well the hot air furnace at our factory, and later when the user gets the hot air furnace, the user only need to connect the hot air furnace to the sand dryer directly by themselves. It will save the user much time and cost.
When the handling capacity is bigger than 30th, the fluid bed furnace will be the best choice. The fluid bed furnace's heat efficiency is more than 95%, and you also can use the low level fuel such as brown coal, etc.
