Iron Ore Dryer
Capacity: 130-370 t/h
Power: 220-560 kw
Customization: support
Certificate: ISO, SGS
Material: limestone, clay, coal powder, slag, metal concentrate, tailings, etc.
Iron ore dryer, also known as a mineral dryer, is a kind of rotary drum dryer. It is available in handling a large number of bulk materials, such as limestone, clay, coal powder, fly ash, slag, metal concentrate, tailings, and other materials that have certain humidity. The iron ore dryer features reliable and simple operation, strong adaptability, and large processing capacity, widely used in the metallurgy industry, chemical plant, power plant, mine industry, cement plant, etc.
In iron ore pelletizing plants, the iron ore dryer is one of the important pelletizing equipment. During the production process, the raw material (iron ore concentrate) moisture is generally between 11% – 15%. Before they are fed into the pelletizing disc, they should be dehydrated first. The main function of the dryer is to remove water from the iron ore concentrate. The second is to mix the added auxiliary material (bentonite) with the iron ore concentrate by using the cylinder rotation so as to facilitate the smooth progress of the next process.
Traditional drying equipment has the disadvantages of large investment, large space occupation, and low thermal efficiency. Iron ore dryers manufactured by AGICO overcome these shortcomings, and has high production efficiency, reasonable price, and long service life, bringing high benefits to customers.

Iron Ore Dryer Working Principle
The iron ore dryer is mainly composed of a rotary cylinder, transmission device, reducer, supporting device, sealing device, lifting flights, self-cleaning device, conveying device, etc.

The main body of the iron ore dryer is a slightly inclined and rotatable cylinder. Wet materials enter from the higher end through a feeding pipe and move continuously to the discharge port at the other end. In this process, the wet material directly or indirectly exchanges heat with the heat carrier to achieve the purpose of drying and then discharged through a belt conveyor or screw conveyor.
Usually, the heat carrier enters from the lower end and contacts the material in a counter current. However, it can also flow into the cylinder in parallel with the material.
The inner wall of the cylinder is equipped with several lifting flights, which are used to throw up and scatter materials. It enlarges the contact surface between the material and heat carrier for increasing the drying rate and promoting forward movement.
The heat carrier is generally divided into hot air, flue gas, and so on. After heat exchange, the material particles it carried should be filtered out by a cyclone dust collector. If it is necessary to further reduce the dust content, a pulse jet bag filter is a good choice.

Highlights Of Iron Ore Dryer
The coal consumption is 1/3 of the traditional dryer.
After drying, the material moisture can reach 0.5-1%, and it is adjustable.
The dryer has strong shock resistibility, stable running, and high reliability.
It adopts a multi-combined material lifting device to improve thermal efficiency.
The material discharge temperature is less than 50℃. They can be stored directly without cooling.
Its thermal efficiency is up to 80%, which is 45% higher than the traditional single-cylinder rotary dryer.
Compared with the traditional dryer, it reduces the floor area by 40% and the investment in civil engineering by 50%.
The main body of our iron ore dryer is made of alloy steel plate. It is 3-4 times more wear-resistant than the ordinary steel plate.
The iron ore dryer produced by AGICO can run continuously without air leakage. It has the advantages of a simple structure, low maintenance cost, and can be installed within a few hours.
