The Pulp and Paper Making Processes

THE PULP AND PAPER MILL Although there are several chemical and mechanical pulping methods used for delignifying wood (table 2l), separating fibers, and removing discoloration, all integrated pulp and paper mills involve the same general steps in the manufacture of pulp and paper. These steps include: 1 ) raw material

Ion Milling System IM4000Plus

The IM4000Plus Ar ion milling system provides two milling configurations in a single instrument. Previously two separate systems were needed to perform both cross section cutting (E3500) and widearea sample surface fine polishing (IM3000), but with 's IM4000Plus, both appliions can be run within the same machine.

Grinding and Finishing

• You are grinding a steel, which has a specific grinding energy (u) of 35 Ws/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at m/min. The chip thickness ratio (r) is 10.
