A need for good quality waste papers has become increasingly important for the pulp and paper industry. Under such circumstances. We have concentrated all sorts of efforts to develop waste paper treating machineries to meet contemporary needs. We found the kneading applied to the stock while processing produces a good result in terms of de-inking, and that the dewatering prior to kneading is an important point for de-inking. Double Cylinder Press Machine developed for this purpose is applicable to any type of waste paper stock as well as a virgin pulp. We are, with an original state-of-the-technology and know-how as well as practical experiences in the pulp and paper stock preparation machineries, always at your disposal for the request to improve your stock preparation system and
equipments serving you as a good and reliable adviser.

The patented cylinder-press machine installed immediately prior to the kneading machine allows an enough dewatering of the stock to enhance the
de-inking and its dispersion.

STRUCTURE AND PRINCIPLE

The waste paper stock supplied through the stock-inlet pipe underneath the cylinder vat, is dewatered to a higher concentration between two rotating wire-cylinders covered with respectively different size of wire-mesh, first by a natural filtration and successively by an air-pressurizing at the touch point. The paper stock stick on the finer meshed cylinder is scraped off by the doctor, raked up by the rake-up conveyor and proceeds to the subsequent process. Superior dewatering, higher yield and less trouble-shooting with simple structure and less power.

FEATURES

• Supplied at 3 to 5%, discharged at as high as 15 to 30%.
• Natural vacuum system minimizes power consumption.
• Quick dewatering from a lower consistency to the higher by way of the function of vat, that allows of simple flow of the stock.
• Higher pulp yield resulted from a lower concentration of fibers in effluent.
• Higher performance naturally less space for the installation.
• A uniform treatment against the fluctuation of inlet stock concentration by way of air-cushion pressurizing.
• An easy control of quantity and concentration of the stock by an inverter control.
• Less consumable attachments and parts, and easier maintenance.
