2.2 meter rotary dryer for drying 5 ton coal slime with low temperature

coal slime rotary dryer application
1, In coal industry, dry the flotation clean coal, raw coal, coal slime, mixing clean coal, etc.
2, In building industry, dry sand, clay, limestone, blast furnace slag, quartz stone, bentonite, etc.
3, In mineral processing industries, dry various metal concentrate, tailings, waste residue, etc.
4, In chemical industry, can dry non-thermal sensitive material.
coal slime rotary dryer performance characteristics
al slime dryer has great handling ability, fuel consumption less, low drying cost.
2.High temperature resistant, this dryer can use high temperature and hot air to dry materials rapidly.
al slime dryer expanded ability is strong, design considered production surplus, even if yield increased slightly, also need not changing equipment.
al slime dry adopts “self-aligning type” tug structure,tug match up well with rolling ring, and greatly reduce wear and power consumption.
5.Special designed catch wheel structure, greatly reduces tilt of the equipment which work provides the horizontal thrust.
6.Environmental protection.
7.Dry and moisture control, minimum up to 5% or less, meet material widely.

coal slime dryer operating principle
1. A rolling cylinder which slightly inclines is the main part of coal slime dryer. The wet materials are fed from the higher end of the cylinder when the heating media are being sent through the lower end.
2. Under influence of the gravity,wet materials flow downwards to the lower end and contact the heating media directly or indirectly.
3. There is a stirring plate on the inner wall of the cylinder to
stir materials continuously and make them have a full contact with air stream.
coal slime dryer structure
al slime dryer is formed by rotary body, lifting blade, driving device, supporting device and sealing ring.
al slime dryer is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap.
3. The accessories which are not in the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.

 The simple drawing of coal slime dryer system:

coal slime dryer market outlook
1.With implementation of the strategy of sustainable development, coal and other mineral resources,rational development and utilization has become an important issue,original low value the full development and utilization of lignite is urgent.
2.Use of valuable lignite resources, so that turning waste into wealth, not only can produce considerable economic benefits.
3.This drying equipment can be dry coal slime in ensuring quality of the same premise, reducing the sulfur content of lignite to improve the calorific value of lignite.
4.Improve combustion efficiency, making more full use of coal resources .
Process flow of coal slime dryer
As raw material is sticky, this drying equipment is divided into several section for higher efficiency.
1.Transmission section. Wet coal slime enters this section, then gets full contact with high temperature air, moisture inside gets vapourized. With lifting boards elevate and scatter materials repeatedly, wet coal slime conveyed to next section.
2.Cleaning section. When materials fall down, they are easy to stick on the inner wall of the cylinder. During this process, cleaning device breaks the clumps. This spreads the surface area of heat exchange and improves heat efficiency.
3.Lifting boards section. Wet coal slime is loose and of low moisture content that meet the requirement.
4.Discharging section. No lifting boards in this area. Materials roll to the outlet. The whole drying process is completed.
