as one of the biggest manufacturers of PAC in China,We produce 20 thousands ton spray dried PAC and 30 thousands ton roller dried PAC per year.

Â

We have our own raw materials factory and equipments plant,and helped 7 domestic companies and 3 foreign enterprises built yearly production 3000ton,5000ton,10 thousand ton and 20 thousands ton PAC production line.And supply them the main equipments which produce PAC---roller drier.

Our roller drier have got manufacture license of special equipment peoples republic of china.and we can supply roller drier with different type according to your yearly production

The specifications of roller drier:

Drum Dryer

Working Principle:

Drum dryers with heat conduction is a continuous type drying equipment rotation.Rotation of the lower part of roller,through materials manger adhesion materials a certain

thickeness.Heat transfer by pipeline to the durm wall,conduction to the materials which adhere to the surface of durm that the moisture to evaportate.The dried materials will be scraped by the scraper which installed on the surface of the durm.

characteristic

1.high thermal efficiency.Drum dryers due to heat-transfer mechanism is heat exchange,heat transfer is the direction of unchange throughout the operation cycle. In addition to loss of heat and radiation, other energy used for drying wet materials. Thermal efficiency up to 80% -90%.

2.Flexible working,Wide practical. Drum dryers can be adjusted in many ways,such as concentration of materials,the thickness of adhesion materials, Heating medium temperature, rotation speed of drum.Those adjustment all can change Drying efficiency.This characteristics let its easier to operate and adapt to dry variety materials meets different production requirements

3.Short drying time. In generally ,The drying time of materials only 10 - 15 seconds, more suitable for heat-sensitive materials

4.High Drying efficiency.Because the thickness of adhesion materials usually 0.3-1.5mm in drum wall and unchanging heat direction,so that the speed of surface evaporation can maintain 30-70KGH2O/m2.h

Used on chemical industry, dyestuff, pharmaceutical, food, metallurgical and other industries for drying of liquid and viscous materials
