Sand dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas.
Sand dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. Sand dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters sand dryer, and as sand dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of sand dryer. When material gets high enough to roll back off the fins, it falls back down to the bottom of sand dryer, passing through the hot gas stream as it falls.
This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case sand dryer is called a direct heated dryer.

Heat soak furnace, we often call it tempering furnace. It is the necessary equipment for producing tempered glass.
Why tempered glass break?
Tempered glass could have spontaneous breakage without receiving any external force, which is the nature of tempered glass. The reason comes from nickel sulfide inside the glass. Nickel sulfide is ¦á¡«nis in high temperature during the heating section. When cooled rapidly, ¦á¡«nis can not change correspondingly to ¦â¡«nis of low temperature. The morphic transformation will last for ten of years which lead to spontaneous breakage.
What is heat soaking?
Heat soaking is a destructive process in which a pane of tempered glass is subjected to temperatures up to 280¡ã c for several hours over a specific temperature gradient to induce fracture. This test insures that if there is probability of breakage then the infected panes break inside the furnace at the factory itself. Up to 95 % nis infested panes are usually destroyed inside the heat soak chamber at the factory premises and hence reduce the chances of onsite breakages. The machine is characteristic of computer in-process monitoring and controlling, multi curve display, data storage, record check and curve printing. Extended functions like low temperature frit drying and pre-pressing of bending lamination glass. Customized machines are available.
