Stainless Steel Industry Mini Biomass Salt Drum Dryer Rotary Drying Machine
1. Introduction of Sand rotary drying equipment
FAIR sand dryer used for drying certain humidity range granular materials, such as
1.casting sand which used in dry-mixed mortar and foundry industry
2.small granular clay used in construction and cement industry
3.small granular material in chemical industry which no chemical change, not afraid of heat and dust pollution
2. Application of Sand rotary drying equipment
Durable rotary drum sand dryer is mainly applied for stoving slag, sand, coal, fly ash, iron powder, ore, quartz sand and other particle materials.
1.Powder & particle: Sands, limestone, stones, clay, mineral filter cake, coal, iron sulphate, filter cakes, fly ash, gypsum etc.
2.Damp and sticky material: Coal slime, sewage sludge, bentonite, Kaolin etc.
3.Corrosive material: Distillers ‘grains, Fertilizer, animal dung, slag etc.
4.Biomass material: Sawdust, wood chips etc.

Three Cylinder Rotary Sand Dryer Working principle:
The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
three pass river sand drum rotary dryer is made by our company used on building materials, metallurgy, chemical industry, cement plant for drying of sand, sawdust, wood shavings, chicken manure, iron ore, limestone slag, coal powder, slag, clay stone,etc. This Rotary Drum Drier is composed of rotary body, lifting blade, driving device, supporting device and sealing ring,etc.
For providing you the suitable quotation we need to know the following information:
1. What is the material that you are going to dry?
2. What is the capacity?
3. What is the moisture content both before and after drying process?
4. What is the heat source?
The Rotary Drier is widely used in the field of building materials, metallurgies, chemical industry, cement and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone and so on. It is made of rotary body, lifting blade, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.
1> Low outlet air temperature, longer service life of dust removal equipment.
2>Sizes of lump materials, particles, and powders are less than 20mm can be dried.
3>Gear driving is not required and it’s directly driven by roller, with higher mechanical efficiency.
4>Without the phenomenon of air leakage, the sealing difficulty is totally solved, and the installation can be finished within a few hours.
5>50% of area covers has been reduced compared with the single drum dryer, and land investment reduced by 50%, power consumption reduced by 60%.
6>The self-insulation thermal efficiency of three cylinder dryer can reach above 70% (the self-insulation thermal efficiency of traditional single drum dryer is only 35%), it has remarkable energy saving effect.
7> Final moisture indicators can be regulated easily according to the request.
8>Less than 1% of material moisture can be assured by the three-cylinder dryer, which is the preferred product for the dry mixed mortar and slag powder production line.
