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
CHIP STORAGE AND HANDLING FOR PULP MILLS | Biomass .
· 1 Introduction Pulpmills are among the largest users of woody biomass and typically store and process huge volumes of wood chips prior to the pulping process. Storage volumes of 120,000 BDt (750,000 m³) are not uncommon. The value of these chips is in the tens of millions of dollars, so mills have very specific requirements [.]
HYDRAULICS, AIR ENTRAINMENT AND ENERGY DISSIPATION ON .
The stepped chute design enhances the rate of energy dissipation on the spillway chute, thus reducing the size and cost of the downstream stilling structure. During the last three decades, research into the hydraulics of stepped spillways has been active with a focus on steep stepped spillways for concrete gravity dams (Chanson 1995,2000, Ohtsu ...

Proper Methods for Placing Concrete Good Construction Practice
Placement in Special Conditions Concrete placed in restricted forms by borrows, buggies, cars, sort chutes or hand shoveling should be subjected to the requirement for vertical delivery of limited height to avoid segregation and should be deposited as nearly as practicable in it's final position.

Current expertise and experience on stepped chute flows
Current knowledge and field observations suggest primarily three types of design : steep "smooth" chutes, stepped channel and the dropshaft cascade (Fig. 7). The stepped chute design was common also with dam spillways (see above) and Roman engineers built several significant stepped spillways.

CHUTE DESIGN CONSIDERATIONS FOR FEEDING AND TRANSFER
Chute design has been the subject of considerable research, a selection of references being included at the end of this paper [129]. However, it is often the case that the influence of the flow properties of the bulk solid and the dynamics of the material flow are given too little attention.
