Constructing Straight Pores and Improving Mechanical ...

Abstract: The large-scale accumulation and pollution of solid mining waste is an urgent issue. Coal gangue is a prominent type of solid waste, and shows promise for use in high value-added products due to its content of many important compounds, including SiO 2 and Al 2 O 3.This study proposed the preparation of highly porous ceramics from coal gangue, coal slime, and coconut palm fibers.

Comminution

Solving Eq. (5.1b) for n=3/2 gives the same form as Eq. (5.4) with the constant 2 K ahead of the bracket. In effect the 2 K is replaced by (10×Wi), which is convenient because Wi becomes equal to W in the case of grinding from a theoretical infinite feed size to 80% passing 100 µm.The Bond model remains the most widely used, at least for the "conventional" comminution equipment in use at ...
