The Description of Coal Slime Roasting Machine 

Mechanical structure:Coal slime roasting machine is composed of heat source ,beaten device ,belt conveyor ,feeder ,rotary drum ,belt feeder ,induced draft fan (available in :roof fan ),discharger and distribution box .

Working principle :coal slime is in sticky form ,therefore, the drying process consists of the following procedures:

1..Conducting Area ,coal slime was fed into this area ,then contact hot air while water was promptly evaporated ,the materials are stirring by the shoveling plate ,and would not bond together but enter into the next work area .

2..Clean-up Area ,when the materials was lifting ,they are easily tend to stick to the wall of rotary drum, in this circumstance ,the cleaning device combined in the coal slime dryer could properly clean the adhesive materials .During this process ,the cleaning device also play a role of crushing on them ,thus increasing the heat exchange area and the improve the drying rate .

3.Tilted Lifting Plate Aerate .The wet slime in this field has shown low moisture loose state ,and cohesive phenomenon is no longer exited .thus coal slime reach the required state after heat exchange .

4. Discharge Area.materials in this section taxiing to the discharge opening ,completing the roasting process.

The Main Features of the Coal Slime Roasting Machine

1. With strong anti-overload ability ,large capacity , low fuel consumption and low cost .

2. Adopting downstream drying method ,flue gas from the same side with the wet materials into the machine ,so high temperature flue gas can obtain a full evaporation,consequently ,the thermal efficiency is enhanced .

3. According to different materials ,we can change operation parameters of dryer to ensure the effect of heat exchange .

4. The new type feeding ,discharging device can get rid of feeding jams,nonsequence,nonuniform ,and reduce the burden of dedusting system.

5. The improved inside structure of the roasting equipment enforced the cleaning and heat conduction effect on the dispersed materials,eliminated the sticking phenomenon ,strengthened the adoptability to the moisture and stickiness of coal slime .

6. The Coal slime drying machine greatly reduced the attrition of underroller ,thus cylindrical shell work stably and reliably .

7. It used self-aligning type underroller device to ensure the ever linear contact between underroller and rolling ring and greatly decrease the abrasiveness and power loss .

8. You can control granularity and moisture of finished product according to your requirements .The moisture and fineness of final product canbe controlled within 8%and 8mm respectively .
