MGT series of energy-efficient drying drum system mainly consists of six parts that are raw material loading systems, combustion heating system, dehydration systems, environmental dust removal system, power distribution and control systems and product transportation system.
MGT series of energy-efficient drying drum system is self-developed which is with complete system that will meet the different requirements from Chinese customers and overseas.
Drum diameter: 1.5 m -4.2 m
Drum length: 8 m -38 m
Unit processing capacity: 10t / h-300t / h
Material moisture range: 20% -40%
Index after drying: 8%-13% water content after drying
This drying system can process high moisture content materials such as slime, lignite, coal, flotation clean coal, mixed coal, coal power plant fuel, blast furnace slag, clay, limestone, sand, quartz stone, metal concentrates, waste, tailings, sawdust, aggregate, waste mud and other materials.The moisture content can be reduced to 8% or less which will completely solve the problem of storage and transportation to improve the efficient utilization.
Dryer Technology -core technology :
1. Independently developed without unpowered spiral propeller which is solving the problems of materials sticking and that also improve the uniformity of material and prevent the materials from returning.
2. Unique internal structure will prevent from material blocking and sticking, which will meet different drying requirments of various types and moisture content materials.
3. There is equipped with delay mechanism inside the drying drum that makes the material alternating motion in the drum to improve the volumetric efficiency to ensure the drying effect.
4. It can change the running parameters according the material properties (moisture content, ash content and size), so that the material in the dryer drum will form a complete section of material to ensure the heat exchange.
5. Running speed of drying drum can be automatically adjusted according to real conditions,which will adpate the uneven input materials.
6.It achieves "zero horizontal thrust" for the dryer to ensure smooth and reliable operation.
Dryer Technology -feeding system :
1. Independently developed GLB type buffer feeder solves the problems of uneven feeding caused by intermittent discharging offilter press,which meets the requirements of feeding quantitative, uniform and continuous.
2. Improved feeding equipment make the feeding more uniform and smooth, and the heat resistance and reliability improved.
3. unique charging and discharging seal equipment, ensures high thermal efficiency while achieving a flexible material transport.
4. Self-developed cold air isolation technology, avoid heat loss maximally, which not only improves the thermal efficiency of the drying system effectively, but also avoid dust spillover impact on the environment.
Dryer Technology -Environment cleaning system :
1. Integrated design of desulphurization and dust removal , using the spray mode, self-designed glass steel spiral nozzle, to ensure water mist is full contact with dust and harmful gases, dust removal efficiency ≥98%, sulfur dioxide removal rate ≥90%, smoke Ringelmann blackness <1.
2. Development of modified high temperature glass fiber reinforced plastic material, completely solve the the problem of corrosion, wear and clogging, and heat resistance can be up to 300 ºC instantly(Through constant temperature test 24 hours ), and the aging is up to 20 years.
3. More than 90% of dust spray water can achieve self-circulation.
4. The successful application of bag filter is a new way of thinking for high temperature and high humidity dust tail.
1. Set up power distribution system,control system,computer system and industrial television monitoring system according to process requirements to achieve a centralized and in-situ monitoring of intelligent for drying system.
2. Automatic detection function for oxygen content, which can be realize online detect and limit alarm for oxygen content .
3. Real-time detection measuring function for input and output material which is easy for production and sales management.
4. Monitoring and upload for each production and process step and equipment operation which help managers to konw the real-time operating conditions.
