Introduction:
A refiner segment is used in disk refiners for the treatment of lignocellulose-containing materials. The refiner segment has a radius and includes an upper surface, an alternating pattern of pluralities of bars extending upwardly from the upper surface of the refiner segment to a predetermined bar height, and intermediate grooves having a predetermined groove width therebetween, and a plurality of dam members disposed in the intermediate grooves and extending upwardly from the upper surface of the refiner segment to the predetermined bar height, each of the dam members being arranged at a predetermined angle of less than about 30° with respect to the radius of the refiner segment, the dam members extending across entire predetermined groove width of the intermediate grooves at the predetermined bar height.
The refiner segment plate is the heart part of refiner and requests good wear resistance and excellent strength. Also, a premium design of the pattern is required to guarantee the performance.
We supply refiner segment plate in multi-element material, with special casting technology and precise mechanical machining.
Characteristics:
1, High wear resistance and high strength.
2, Durable pattern and long-life segment plate which can decrease the consumption and save production time.
3, We can supply all kinds of blades for refiner and produce them in tailor-made.
