Introduction to Rotary Sand Dryers
Rotary Sand Dryers are one of the typical applying area of rotary dryers due to its reliable performance, high efficiency and low manufacturing cost. Our factory has been making rotary dryers for drying sand since 1950s. Back then only single-pass rotary dryers were available for all drying processes. As entering 21st century, all industries facing more and more environmental challenges and higher demand for energy efficiency. Our factory started to R &D Triple-pass Rotary Sand Dryers in 2002, which now has basically replaced conventional single-pass rotary dryer in sand drying plants.
Various sand: eg. River sand, sea sand, mining sand, molding sand, etc.
Grain sizes: 0.075 to 10mm typically
» Output Capacity:
3 t/h to 110 t/h
Final moisture: ≤ 0.5%
» Motor Power:
4 Kw/h to 88 Kw/h
» Drying Temperature:
Max. 750 oC
Features of Triple-pass Rotary Sand Dryers
⇒ Thermal efficiency improved by 40%
⇒ Coal consumption (as fuel) is 30% of conventional dryers.
⇒ Outer shell temperature reduced to less than 60 oC; exhaust gas below 120 oC. filter bags can work twice longer and no need for cooling.
⇒ Floor area reduced by 40% to 60% by comparison
⇒ Lowered investment for the same capacity.
⇒ Improved sealing and improved reliability.
How Does It Work ?
|Triple Pass Rotary Dryer has 3 drying zones in the 3 cylinders (internal one, middle one and external one) which construct the rotating body. Heat processing of a product with high moisture content is done efficiently in those 3 drying zones. The product is put in from the inlet of the hopper, sent to the internal cylinder where heating of the product is made, then moves to the middle cylinder where evaporation of moisture is promoted further. The solid constituent of the product is gradually broken into pieces and discharged from the outlet via the third final drying zone. The hot air produced in the furnace is sent to the internal cylinder, passes through the middle and external cylinders. The hot air is then sent to the cyclone where dust is removed|
