Chapter 3, Problem 3.14P
Interpretation Introduction

(a)

Interpretation:

Calculate the bulk density of the materials in the bag.

Concept introduction:

Specific gravity is defined as:

Specific gravity = Density of the substance Density of water

Interpretation Introduction

(b)

Interpretation:

Calculate the weight of the filled bags. State your assumptions.

Concept introduction:

Specific gravity is defined as:

Specific gravity = Density of the substance Density of water

Interpretation Introduction

(c)

Interpretation:

Briefly explain whether the crushed limestone particles fill 50-L bags.

Concept introduction:

50-L bags are used to store Limestone (Calcium Carbonate). It is given that the void fraction of the particulate matter is 0.3 and the specific gravity of the solid calcium carbonate is 2.93.

A ball mill is used to crush the limestone and turn them into powder.

The ball mill is a device used to crush solid particles, inside ball mill there are rotating steel balls. The solid particles crush into small particle due to the impact of these steel balls.
