Introduction of sludge Dryer

Sludge dryer produced by Hongji Machinery is mainly used for dehydrating and drying sludge,thus reducing the water content and volume of sludge.It has many advantages such as strong adaptability,high heat utilization rate,uniform drying effect,fewer clean-up times,convenient maintenance,etc.

Sludge dryer is widely used in building material,metallurgy,chemical industry,cement industry,etc.It is used for drying sludge,sewage and slurry,including urban sludge, municipal sludge,sewage plant sludge,industrial sludge,metallurgy sludge,light industry sludge,coal sludge,mineral sludge,foundry sludge,textile sludge,electroplating sludge, activated sludge,sewage sludge,petrochemical sludge,paper-making sludge,printing and dyeing sludge,tanning sludge,slaughter sludge,pharmacy sludge,etc.

Working principle of sludge dryer

Sludge is fed into the dryer by a feeding device through an oblique chute;as the dryer rotates,the sludge is lifted up and scattered by lifting blades,and hot air preheats and drys the sludge to a certain extent;when the sludge falls down to the grate type blades,it is dried by the hot blades;at the same time,the hot air drys the sludge when it is lifted up and down by the blades;also,the cleaning-up device inside breaks up the lumps or pellets which are already formed in this process;finally,dried and loose sludge is discharged from the discharging end as final products;

Features of sludge dryer

1. Wide applicability,available for many kinds of materials.

2. Simple operation,stable performance;

3. Low investment,high efficient and capacity;

4. Low cost in maintenance;

5.High quality heat exchangers can control negative and positive motion,and improve drying quality.
