A variety of waste products are created throughout the paper production process. Paper and pulp waste is traditionally disposed of in a landfill, but doing so can present problems as the high chemical content of these wastes can cause harm to the surrounding environment if not disposed of properly.

Dingli Pulp and Paper Residuals Drying System is custom-designed and manufactured to improve a customer's individual drying needs; whether it be reduction of mass for transportation or preparing the waste stream for an alternate use. These drying systems are designed specifically to dry each customer's product to their desired output moisture content range.

When the moisture content of paper and pulp sludge is reduced, the material can be sold for reuse or recycled, avoiding the costs of landfilling and leading to potential economic benefits for the producer. Recycled paper and pulp waste can be used to make a variety of products, including paper products, textiles, diapers and feminine hygiene products.

Drying paper and pulp waste makes it easier to store, handle and transport. Once the moisture content of the material is sufficiently reduced, it can then be processed and recycled for reuse.



Dingli Pulp and Paper Drying System is custom-built for each client. Systems may include the feed horizontal conveyor, rotary dryer, combustion chamber with burner, secondary air blower, ductwork, cyclone or baghouse, induced air blower, and controls system.

The wet material is fed into the rotary dryer by a feed conveyor.  The material then travels through the drum rotating as it is exposed to a stream of warm air. As the drying is completed, the material exits the dryer through the knock out box. The moisture content of the dried material can be determined based off the customers desired range.
