Energy saving in paper making process

lk1In the process of paper making, most of the energy saving is related to improving the energy efficiency of the drying process and the utilization of the waste heat. In general, pulp and paper energy costs accounted for about 10% to 35% of the cost of production; consumption of vacuum consumption accounted for 15% of paper electric power consumption to 18%, most of the vacuum energy is supplied to the vacuum roller, suction tank and vacuum suction tank; drying is the highest part of energy consumption in the production of paper. The key factor to reduce the energy consumption is to increase the dry degree of paper after press. Continue reading “Energy saving in paper making process”

Triple Layer BOM Felts, Paper Making Press Felts

triple-layer-press-felt-structure-webTriple layer BOM press felts include the structures of 1 +2, 2 +1 and 1 +1 +1 composite felts. The press felts can be applied to more than 200 kN/m linear pressure and possess the features of good flexibility and permeability, excellent size stability, long life performance. Triple layer press felts are used in high speed paper machines for suction complex press, large diameter nip roll press and shoe press to produce high-grade news-prints, writing papers, paper-boards etc.

Double Layer BOM Felt, Paper Making Press Felts

double-layer-press-felt-structure-webDouble Layer Press Felts include 1+1 composite structure and double layer of MD yarn structure. The 1+1 composite structure consists of two layer base meshes of different thickness. Both of these base meshes can be changed in construction and sizes to suit the requirements of different paper machines.

Spiral dryer fabrics, SLDF

spiral-fabric-structure-webSpiral dryer fabrics are commonly used in the papermaking industry for transporting and drying the aqueous media there found. More broadly, spiral fabrics are used as filter media for wet, dry, hot and cold solutions and dispersions. Spiral dryer fabrics provide the best resistance to abrasion.

Side View-Weaving Struture

Commonly known as 2.5-layer forming fabric, extra support double layer forming fabrics are to further improve the characteristics of double-layer design. It’s a standard double layer forming fabric with an additional weft yarn on the sheet side of the fabric. There is an improvement in sheet formation, smoothness, reduction of wire mark and better cleaning of the showers. Extra support double layer forming fabrics are commonly used in newsprint and fine papers production or in applications that use very short fibers.
