Magnesian chromite Rotary Drum Dryer from China

Mechanical structure and working principle

Drying equipmentCoal slime dryer mainly by the heat source, scattered device, belt type feeder, feeding machine, rotary roller, belt discharging machine, exhauster, unloading feeder and distribution ark constitutes. The working principle of slime dryer, because it has certain slime following adhesion, the drying process in wet coal slime into dryer after divide the following several working area:

One is the guide material area, wet coal slime into this area and high temperature hot air contact evaporated quickly moisture, materials in a large guide Angle of copy plate, XingBuCheng binding copy move was imported next working,

2 it is clear zone, wet coal slime in this area is copy plate start to copy material curtain state, material formed fall easily formed binding drum wall phenomenon, in this area because of equipment design have cleaning device, cleaning device facilitates very reasonably clean the wall adhesion materials, in the process, cleaning device for material regiment ball agglomerate also play crushing effect, thus increasing the heat transfer area, improving drying rate,

Three is tilted Yang stripper plate area, wet coal slime in this area has become low moisture loose state, material within this region already has no binding phenomenon, passes through heat after material to reach the required moisture state, entering the final discharge area,

The fourth is discharging area, roller in this area will not set copy plate, material in this area is rolling taxi to finish the whole discharging mouth drying process.

The main character

1. The dryer resistance overload ability strong, large quantity, fuel consumption less, dry cost is low;

2.adopt co-current drying method, smoke and wet materials by the same side into the dryer, can use obtained high temperature flue gas evaporation strength, dryer outlet temperature of low and high thermal efficiency,

3. According to different material properties change operation parameters, make the material in the dryer cylinder body can form a stable all broken fabrics act, qualitative heat more fully,

4.materials feeding and discharging device, to eliminate the drum drying machine feeding jams, discontinuity, uneven regurgitation feeding etc. Phenomenon, reduced dust removal system load,

5. New internal structure, strengthened the already scattered materials for the cleaning and heat transfer effect, eliminates the cylinder body wall with sticky phenomenon, for material moisture, sticky adaptability stronger;

6. The dryer has realized "zero horizontal thrust", greatly reducing the block roller wear, cylinder smooth operation and reliable;

7. The dryer adopt "self-aligning type roller device", make roller and coordination of the tyre-roller forever linear contacts, which greatly reduces the wear of power loss,

8. Optional according to customer's requirement control product size and moisture, drying slime water when products can reach 8% below, and the particle can be controlled in 8mm below.
