Techmelt Refiner Plates and Conical Fillings

The Theory of Refining

Refining is a mechanical action, which was held on the cellulose fiber, which aims to modify its structure giving it features required for a good formation of paper.

Precisely by changing the structure of the fibers on the basis of the characteristics and the quality of the sheet desired, the sector of refining in paper mills is the one with the greatest impact in the final product, in addition to being in the position of main consumer of energy.

Intensity of Refining

Intensity of Refining is calculated with the aim of measuring the severity with which the refining and performances. The results are used to determine the project of plates design.

The value of the cut length increases in plates with bars thinner and smaller spaces, which provides a lower value of Intensity Refining.

Cost Reduction

The consequent reduction in the cost of manufacture of paper there is in the light of the less production of fines, increase of the machine speed, reducing the weight on the basis of the gain in bulk, the reduction of products manufactured out-of-specification and the reduction of complaints from customers.

With a number of crossings bars (impacts) much higher (in the light of the greater length of bars) the probability of reaching almost totality of the fibers, is also higher. This action of refining smoother causes an increase in the specific area of the fibers through the fibrillation, providing a better resistance to traction and better drainage (Freeness, CSF).

The length of the fibers is preserved with the lower incidence of cutting. The collapse of the fiber is reduced, also reducing the loss of bulk.
