Introduction of Nickel Ore Rotary Dryer
Nickel is a very important metal in stainless steel, smelting nickel iron through red earth nickel ore can replace expensive nickel plate. Red soil nickel ore is particularly large in water content, generally contains about 35% of free water, 12% to 15% of crystalline water and other compounds of the burn loss. According to nickel ore’s characteristics of high moisture, complex composition, stickiness and large-scale clumps, Dongding researches and manufactures the nickel ore rotary dryer system, whose capacity up to 2000 tons per day. After treatment of the nickel ore, final moisture is about 5%, which achieves the next and large-scale processing requirements.
Advantages of Nickel Ore Rotary Dryer
01
Wear-Resistant Drum
The drum interior is made of wear-resistant manganese plate, 3–4 times more wear-resistant than ordinary steel plate.
02
No Heat Leakage
A unique sealing structure prevents thermal energy leakage.
03
Direct-to-Warehouse Discharge
Discharge temperature stays below 60 ℃, so dried material can be fed directly into the warehouse without cooling.
04
Low Investment
Low investment, low operating cost and a short investment-recovery time.
05
Multiple Heat Sources
Customers can choose the heat source that fits their situation, and we can design customized solutions.
06
Low Investment & Fast ROI
Low equipment investment and operating cost with quick return on investment.
Working Principle of Nickel Ore Rotary Dryer
Raw materials are fed into the hopper through belt conveyor, and then enter the drying system through feeding mechanism. The guide device installed in the rotary dryer lifts the materials to the top and then drops them. When the material falls, it is broken by the high-speed rotating blade in the dryer. It is repeated until move to the outlet. At the same time, the hot air generated by the high-temperature heat source enters the dryer to fully contact with the materials, so that the materials can be dried quickly, and then discharged through the conveyor at the discharge end.
