HZG SERIESDIRECT HEATING ROTARY DRUM DRYER

Waste heat air or heat exchange air enters the rotary dryer and directly exchanges heat and mass with wet sludge in the channel. It is equipped with a special crushing device (specially designed structure) to quickly evaporate the water in the sludge. The smaller sludge particles are discharged from the dryer and collected together with the gas through the outer channel, while the larger sludge particles stay in the dryer for a longer time until drying is completed. Partial exhaust gas is extracted and treated by a deodorizer to meet atmospheric emission standards (or cooled by water foam dust removal) before being discharged into the atmosphere

To prevent material blockage, a scraper is welded to the drum to form a moving blade, and most of the material is forcibly stirred and sent away by a spiral guide plate, ensuring a smooth feeding process;

The drum is designed with different inclinations based on the material's condition to ensure smoother discharge

The machine has a simple structure, reliable operation, easy maintenance, and can achieve continuous large-scale production. It can also comprehensively utilize waste gas operations；

Install exhaust gas collection and treatment devices according to different requirements.

According to the characteristics and status of the sludge drying process, different dispersion and crushing devices are used in sections to greatly improve the drying efficiency.

Using special sealing materials to ensure sealing effect and greatly improve service life

The bearing adopts a cooling device to reduce the operating temperature of the bearing and extend its service life

Indirect heating can be used to reduce exhaust air volume and improve heat utilization efficiency

Adopt different sheet cutting forms according to different states of materials to reduce the degree of bonding

Adopt different feeding methods based on material characteristics to prevent blockage of the feed.
