The mechanical treatment of paper pulp fibers to impart to them the appropriate characteristics for papermaking. A part of the stock preparation phase of papermaking, refining is the most important aspect of the process, as it is here that the characteristics of the cellulose fibers and the composition of the papermaking furnish that comprise paper are determined, which affect how the fibers ...
A paper machine (or paper-making machine) is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by filtering out the fibres held in a paper stock and producing a continuously ...
APPLICATION OF LOW CONSISTENCY REFINING OF PULP IN PRODUCING MULTI-PLY FOLDING BOXBOARDS Hanya Hemasian Ettefagh Master of Applied Science Department of Chemical Engineering and Applied Chemistry University of Toronto 2016 Abstract In this study, the effect of using low consistency refined (LCR) pulp in the middle-ply furnish of
The load on a refiner motor is controlled by adjusting the motor load setpoint by monitoring load applied by the refiner and the plate gap between the refiner plates to define the curve of the load versus plate gap relationship. This slope of load versus plate gap relationship is estimated and when the sign of the slope of the curve changes sign indicating operation in an unstable zone of pad ...
Impact of Pulp Consistency on Refining Process Conducted under Constant Intensity Determined by SEL and SEC Factors. Konrad Olejnik. Specific Edge Load (SEL) and Specific Energy Consumption (SEC) are nowadays the most popular parameters for defining the intensity of pulp refining. As a result, these factors are widely used in industrial practice.

Pulp, paper and board mills worldwide trust J&L Fiber Services, a refiner plate manufacturer, to help optimize their refining processes.We carefully research and analyze every aspect of refiner plate design and performance so that our refiner fillings excel in the rigors of pulp, paper and board production.
derivation of refining intensity for mechanical pulp refiners is shown in Fig below. Figure: Schematic of pulp flow in refiner Consider an element of pulp, dM, at radius, r, and conduct a simple force balance: F =− − +CF F bSrr12 Here, C is the centrifugal force, F are friction forces between the pulp and discs and S is the steam drag.
Additional refiner plate trials are scheduled to further optimize the energy/pulp quality relationship. The next step planned is to maintain the FiberMaxX-EX™ rotor plate and utilize a directional FiberMaxX™ stator plate pattern. Directional plates utilize the angle of the plate bars to either hold or feed the pulp in the refining zone. The bar
