Dewater Reject from Paper Mill

At many paper mills, paper recycling is part of the process. When the paper for recycling arrives at the mill it needs to be sorted from plastic and other unwanted materials. Special paper mill equipment is used for this process where large amount of water is added to the pulper where the paper is dissolved, and the plastic and other materials are removed. After this process the waste is naturally very wet and very heavy.

The reject causes several problems in the paper industry as it is difficult to handle and expensive to transport. By disposing of the very wet waste a large amount of the water is removed from the factory instead of being re-used in the production. Add extra cost for sending the reject to landfill, which is very expensive.

Separating the Water from Paper Mill Reject with a RUNI Screw Compactor

The RUNI screw compactor is a great solution to the problem as the machine dewaters the paper mill waste (reject) in a continuous process leaving the reject so dry that it can go to incineration instead of ending as expensive and injurious waste to the environment in the landfill. At the same time the weight of the waste is significantly reduced which lowers the transportation costs, and the water that has been separated can be reused in the pulper.

The conditions at papermills are demanding and they are running all year round. The reject often contains abrasive element like sand. This demands a machine of high quality.

The RUNI SK370 screw compactor has been used for this purpose for many years and has proved itself to be a liable and strongly built machine. With its reinforced screw and heavy duty machine body it is designed to work 24/7 with a capacity of 5000 kg per hour of the paper mill waste.
Exiting the RUNI the paper mill reject has a dry matter of around 75 % (depending on the mix of the reject).
