Brown coal drier 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.
Brown coal drier performance characteristics
1.Brown coal drier has great handling ability, fuel consumption less, low drying cost.
2.High temperature resistant, can use high temperature and hot air to dry materials rapidly.
3.Brown coal dryer expanded ability is strong, design considered production surplus, even if yield increased slightly, also need not changing equipment.
4.Brown coal dry machine 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.
Brown coal drier operating principle
1. A rolling cylinder which slightly inclines is the main part of a 3 drum 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 airstream.
4. Having been dried, the materials are conveyed to the discharge end.
Brown coal drier structure
1.Brown coal drier machine is formed by rotary body, lifting blade, driving device, supporting device and sealing ring.
2.Coal dryer machine 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.
Brown coal drier machine 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 dryin equipment, can be dry and brown in ensuring quality of the same premise, reducing the sulfur content of lignite to improve the calorific value of lignite.
Improve combustion efficiency, making more full use of coal resources .
Process flow
As rawmaterial 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 is 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.
Working principle
The wet materials, first scattered via special feeding scattering device, then wet materials is sent to the feeding machine by band-type feeder, and then wet materials is conveyed/delivered into raw materials drum dryer roller by feeding machine, materials in stirring function of shoveling plates which are equispaced in the drying roller, homodisperse and fully contact with hot air, to achieve the purpose of heat transfer and mass transfer. The slurry after drying in the end of roller discharge finished products from the star-shape discharger, the belt discharging machine output the dried products, and that complete drying process.
