Disc deflakers D and DR are designed for deflaking waste paper, machine broke, chemical pulp and knotter screening pulp and other sorts of rejects from separators.
Disc refiners D, DR a 2DR are used for refining paper stock. A wide range of refining discs provides perfect mastering of the whole refining process from fiber cutting up to high fibrillation.
Design
Refiners and deflakers are delivered as single-disc machines with one working zone (sizes D1, D2, D3, DR2, DR3) or as double-disc machines with two working zones (size 2DRT2, 2DRT3). The capacity and efficiency of deflakers and refiners is continuously adjustable in a direct dependence on actual machine load ranging from 7 to 250 tpd.
Functional elements
Wide range of refiners allows perfect operation of the all refining process from shortening to the high fibrilation.
Setting of requested technological parameters and provision of the operation is realized by the sensors of steam pressure installed on inlet and outlet pipeline. Operating control and automatic regulation of disc refiners and deflakers is based on a control with automatic unit. When the machine is installed into a computer-controlled line, the computer fully provides the regulation of refining and deflaking processes.
