Product details

26.7Meters 5 Layers Chain Plate Dryer/Conveyor Dryer

Brief introduction of Conveyor Dryer:

Chain Plate Dryer, named conveyor dryer or heat chamber also, which is re-designed and updated based on traditional mesh belt dryer by DAYANG BRIQUETTE NMACHINERY. Dryer is mainly used to dry the coal/ charcoal/mineral briquettes from press machine by hot air supplied by stove, final briquettes moisture content can be up to 1%. The fuel can be coal,charcoal or biomass briquettes/pellet.The length and layer of dryer is custom-made based on customers briquettes material,size,moisture content and final briquettes moisture request also. The max length upto 40.7 meters and max layer up to 5 layers.

The dryer is composed by stove(built at site or fabricated at factory), draught fan for hot air and moisture out, hot air pipe, drying body, chain plate, driven system and cabinet also.


Working Principle Conveyor Dryer:

Hot air route: The hot air will be pumped out from stove by draught fan, and then to the dryer through the hot air route assembled two top and side of dryer. Most importantly, the hot air will be separated into the dryer evenly by the pipe with outlet pipe assembled inside of dryer and connected two side of drying box, which is our new designing to solve temperature inside dryer is not evenly. Moisture will be pump out from the center of top of dryer by other draught fan. 

As for briquettes: coal briquettes will be feed into dryer by conveyor from feed port assembled at the top of dryer. And then briquettes will laying evenly on the chain plate and following the movement of chain plant until to the end of first layer. Now, the briquettes will fall down to the center of first layer (check the drawing), which is only realized by our new designing chain plate and special designing device, which will make full use of space inside the dryer to speed up the drying process. The briquettes will fall down to the second layer top by the same with first layer, and then to second layer center and then to third layer top, until to the discharge port!  Usually, the last layer for 5 layers dryer is assembled with traditional chain plate used to collect the dust generated during the drying process, which is automatic and speed can be controlled.


Normally, the drying process will be set at two hours half or three hours, mainly depends on moisture request. Such as for charcoal briquettes, drying time are set at  4 hours even more, and one kinds of iron ore briquettes, only two hours half, and one kinds steel making dust only two hours, moisture can be less than 1%.

Advantage of Conveyor Dryer:

1, Higher Drying Efficiency;

Traditional mesh belt dryer, the briquettes will following the mesh belt running and fall down to the second layer at the end of first layer and then to the third layer until discharged out the dryer. But now, chain plate dryer is greatly changed! The briquettes will not fall down to the second layer at the end of first layer, they will fall down to the middle space of first layer which is existing in mesh belt dryer and chain plate dryer. Which is means the same length inside dryer can load and drying double times briquettes by one cycle running. Take 20.5 meters and 3 layers mesh belt dryer as sample, total drying length only 61.5 meters, but as for chain plate dryer, that will be 123 meters. Which means,drying speed can be faster by request same drying time!

2, Less Space Request;

Because of reasonable effectively utilized middle space in each layer, we can choose the shorter (small) size dryer by same drying production capacity! Most importantly, investor can save much money in the space and cost for dryer;

3,Less Final Briquettes Damage Rate;

The chain plate we designed is new kinds of chain plate, which is only 150mm small plate for each section! Meanwhile, the middle space in each layer is only 180mm! The chain plate will follow the channel running, at same time the briquettes will slide to other layer slowly, but not throw to other layer. The briquettes are protected well during the drying process!

Compared with mesh belt dryer, two layer height more than 350mm, some of briquettes will be broken little during the first layer to second layer; Height for vertical dryer is more than 7.5meters, many briquettes will be broken during to feed the briquettes into dryer!

4,Running Stability and Less Spare Parts;

Chain plate is custom-made by steel plate, which is strong enough to support the weight of briquettes and tiny shaped changed during the full loading briquettes and drying process. Meanwhile, the chain plate will run following the channel welding in the structure inside the dryer, running resistance is very less and power request is also small;

5, Automatic dust cleaning device.

One simple chain plate are assembled at the bottom of bottom of dryer, which is used to collect and discharge the dust generated during the drying process! No need extra work to clean the dust at the bottom of dryer, which clean the fire accident risk also!

ZHENGZHOU DAYANG BRIQUETTE MACHINERY CO., LTD, who is professional at coal/charcoal/mineral powder briquette press machine and coal/charcoal/mineral briquettes plant designing and manufacturer more than 20 years, service for hunderds of briquettes machine and briquettes plants customers from domestic and abroad! After thousands of redesigning & updating and hundreds of customers test, we are glad to recommend our key technology connect rollers for press machine and chain plate dryer. Connection rollers for briquette press is greatly short the time to change the rollers and save much cost on rollers; New Designing Chain Plate Dryer is famous for its large production capacity upto 25-30tph, less briquettes damage, and strong drying ability final briquettes moisture content less than 1%!
