Rotary sand dryer also is called sand drum dryer, and it is ideal for drying different kind of sand such as garnet sand, quartz sand, river sand, frac sand, etc.
For the sand materials, they have the similar features of heavy, surface water, good flow ability, can bear high temperature drying methods, etc.
Sunco Machinery professionally design and produce the garnet sand dryer with different capacity. After being dried by the garnet sand dryer, the moisture content of the garnet sand can be less than 3% or as need.
Rotary Sand Dryer is to use high temperature air to heat and dry the wet garnet sand, and get rid of the water from the wet garnet sand, and the water become vapor and to be sucked out by induced draft fan in time.
Burner and Hot air furnace is to burn the fuel and creat the hot air for the
garnet sand dryer machine. There is a wide fuel ranges such as coal, diesel, natural gas, wood pellet, waste wood, biomass fuel, etc, and you can select the most economical fuel, then Sunco Machinery can design and supply the related burner and hot air furnace accordingly.
During the drying process, the wet garnet sand can move in the same direction or opposite direction with the hot air. When the moisture of the sand is not big, then we can make the wet sand moves in the same direction with the hot air. Thus it will have higher heat exchange efficiency, but the disadvantage is that the dry sand goes out through the high temperature end of the garnet sand dryer, the dry garnet sand would be very hot, and people can not load the sand into bag directly.
