What should we pay more attention to the safetly when running the Coal Dryer?

1. Safe Tips for the Coal Dryer

• When operation the Coal Dryer, the machine operator should take the initiative to maintain 500mm distance divide the wheel avoiding in the road or track back feet were crushed in the process.
• Before loading of goods, please fill in the uniform of the material on the conveyor, conveyor so as to stop causing congestion.
• When the machine is in operation, prohibiting within half a meter to stand.
• It’s prohibited fireworks in the driving environment and work preventing fire accidents.
• During is in operation. Please fixed time check the temperature on the thermometer index.

2. Note Warning Signs for the Coal Dryer

• Read the instructions carefully before operate the machine
• The machine is running around non stop people
• Safe distance The nearest distance operate stand is 500mm

3. Safety Operation for Coal Dryer

• Fire prevention maesures: If our equipment is drying easy to ingnite materials, for examply, sawdust, please take care of the dryer on the thermometer, if abnormal, please immediately stop the operation, staff should always control the entry of fuel to feed evenly, do not off.
• Protection against smoke rise: When working in the building, make sure that enough ventilation, do not produce so much smoke, leading to staff safety.

III. Working Principle of coal dryer

1. Under normal conditions, the wet material is clotty coal. If so those clotty coal should be crushed by double-shaft mixer before sending dryer. Just like the picture in following.
2. The crushed wet coal will be deliveried into coal slurry dryer feeder by belt conveyor. At the same time, hot-air made by stove will go into dryer cylinder under the founction of induced draft fan.
3. Along with the rotation of coal slurry dryer, wet coal will throughly making contact with hot-air, thus humidity inside of wet coal will be evaporated.
4. Under the action of gravity, dried coal will move into the discharged hole because the coal slurry dryer is installed with 3-5 degree tilt angle. The temperature output coal is around 70-80 centigrade.

IV. The Maintenance Method for Coal Dryer

1. With reach coal dryer manufacture experience, Guoxin will offer you professional after-sale service. Expecially maintenance is important factor during machine running.
2. Bearing is a part of equipment which take full weight of dryer, the choice of tube have a great influence on service life and rotation rate. So it would be better if we can sure it's clear and with good sealing performance.
3. Gear is also important device, it's the key of transmission, we should do preventive maintenance regularly, remove the rust and add lube. This method also applies to the transmission.
4. Finally, it's cleaning dryer's inner structure regularly. Because the wet material with high moisture easily stick upon the wall of drum, if we don't clearn it regularly, it will be clogging in the dryer. So cleaning method is running dryer without wet materials, thus those sticky material will be dried and out off drum wall, as the same time, rapping on a barrel wall of dryer in the rules.

V. Successful Case for Coal dryer

VI. We can control the drying effect through three aspects:

1. Adjusting the input capacity

2. Adjusting rotary dryer's rotation speed by adjustable-speed motor

3. Adjusting fan's air flow capacity

VII. Impeccable After-sale Service for Coal Dryer

1. Before everything, we should talk about the raw material, its moisture, capacity you need, matters need attention during drying
2. Suggesting you suitable coal dryer such as different diameter: 1.5m,1.8m,2.0m, 2.2m and making sure the width and length of coal dryer.
3. Solving all of your questions, whether technology, shipping, installation or operation.
4. Training technical personnel for customers
5. When the coal dryer is shipped to working-site, our engineer will offer guidance for installing and debuging equipments.
