Voith launches its Pluralis Hot Stock (HS) refiner fillings

Voith expanded its Pluralis family with its new Pluralis Hot Stock (HS) refiner fillings.  The fillings are specifically designed to meet the demanding requirements of pulp mills and to minimize resource consumption, explains the company. In addition, Pluralis HS refiner fillings can reportedly improve paper quality, energy efficiency and overall pulp mill performance.

Voith notes in a press statement that the use of STT alloy provides increased abrasion resistance and longer service life, even under the harsh conditions of a pulp mill with operating temperatures above 90 °C and high throughput requirements. The arrangement of the bars in a non-parallel orientation ensures that the edges intersect at an optimal angle and treat the largest possible percentage of fibres. The design was developed specifically for high kappa pulps and offers the highest production throughput and high shive reduction with extended service life.

Pluralis HS refiner fillings can be used in Voith refiners as well as refiners from other common manufacturers with diameters from 20 to 54 inches.
