Product Description

Coal Drying Equipment Small Rotary Dryer Used in Mining Slag Dryer 

Brief Rotary Dryer Introduction 

Rotary dryer machine is widely used in building materials, metallurgy, chemical industry and cement industry, which is widely used to dry the stuff such as limestone, coal powder, slag and clay.

Rotary dryer can be widely used in:

1. The coal industry: Coal slime, coal, flotation clean coal, mixed clean coal etc.

2. The construction industry: Blast furnace slag, clay, Peng Yun soil, lime stone, sand, quartz stone etc.

3. Ore processing industry: Various metal concentrates, slag, tailings etc.

4. Chemical industry: Non-drying heat sensitive materials

 

Rotary Dryer Features

1. Rotary dryer has Strong anti overload ability, large handling capacity, less fuel consumption, low dry cost.

2. Adopt downstream drying method, the hot air with wet materials enter into the dryer by the same side, can use the high temperature air to achieve very high evaporation strength, the exist temperature of dryer is low, the thermal efficiency is high.

3. According to different materials' properties change operation parameters, make the material in the dryer cylinder body can form a stable all broken fabric curtain, qualitative heat is more fully.

4.New feeding and discharging device eliminate the feeding jams, discontinuous, uneven and returning charge etc. Phenomenon, reduce the load of dust removal system.

5. New internal structure, strengthened the already scattered materials' cleaning and heat transfer effect, eliminated the sticky phenomenon in cylinder

body's inner wall, make material moisture, sticky adaptability more stronger.

6. rotary Dryer has realized "zero horizontal thrust", greatly reduce the wear of block roller, cylinder's operation is smooth and reliable;

7.rotary Drying machine adopts "center-adjusting roller device", make the cooperation of roller and rolling ring always show linear contact which greatly reduces the wear and power consumption.

8. According to customer's request control product size and moisture, when dry slime, the moisture can reach below 8%, particle size can be controlled below 8mm.

The working principle of rotary drum dryer:

How does  Drum Dryer work ?

The wet stock will be firstly conveyed to the hopper by belt conveyor or bucket elevator.Then,the materials will be fed into the feed end through feeding pipe.The slope angle of the feeding pipe is bigger than the natural angle of the material so that they can smoothly flow into the dryer drum.

The rotary drum slopes slightly.The materials fed into the drum from the higher end (feed end) will countercurrent contact with the heating carrying agent(heated gas or flue gas)blew into the drum from the lower end (discharge end).There is another situation that the material and heated gas enter the drum together from the lower end and implement co-current flow contact.

As the drum rotates,the material will move toward lower end under gravity.During the moving process,the material will be heated and dried directly or indirectly by the heat-carrying gas,and then conveyed our of the drum by belt conveyor or screw conveyor.

Specially,lifting plates are mounted on the internal wall,for the purpose of lifting the materials and scattering them,enabling the materials to fully contact with the heated gas so as to accelerate drying rate and facilitate material moving.

Before moving through the dryer drum,the heat-carrying gas will be processed by cyclone dust collector to separate the material blend in the gas.In addition,bag filter or dust washer can be used to further reduce dust content in the gas.
