Refining of Pulps from Ballarpur Industries Limited, Yamunanagar

摘要

Mixed and separate refining studies have been made for pulp blends from Ballarpur Industries Limited containing softwood (Pinus roxburghii), hardwoods, and agricultural residue pulps. Results indicate that separate or mixed refining of wood pulp (softwood and hardwood) as one component and agricultural residue pulp as another component have little effect on strength and printing properties. These are improved when the long fibred (Pinus roxburghii) pulp and the short fibred pulp (a mixture of hardwood pulp and agricultural residue pulp) are each beaten separately and then mixed to give the same blend of long and short fibred pulps. Pulp samples collected from various points in the mill have also been evaluated and are reported in an Appendix.
