Dense Phase vs Dilute Phase vs Mechanical Conveying: Which Is Right for Your Material?

Selecting the wrong conveying method is one of the most expensive mistakes in bulk material handling. Dense phase, dilute phase, and mechanical conveying each have specific application windows — determined by your material's bulk density, particle size, abrasiveness, and fragility. This guide gives you a decision tree you can apply directly to your material.

What's Inside

What this guide covers.

01
The 4 Material Properties That Determine Conveying Method
Bulk density, particle size distribution, abrasiveness, and fragility — how to measure each one and what the values mean for system selection.
02
Dense Phase Conveying — When to Use It
The application window for dense phase: high bulk density, abrasive, or fragile materials where product integrity and pipe wear are the primary concerns.
03
Dilute Phase Conveying — When to Use It
The application window for dilute phase: lower bulk density, non-abrasive materials at moderate throughput where capital cost is a priority.
04
Mechanical Conveying — When to Use It
When screw, belt, or bucket elevator conveying beats pneumatic on total cost of ownership — and the hybrid configurations that combine both.
05
The Decision Matrix
A completed decision matrix for 8 common Malaysian process materials: fatty acid powder, cement clinker, flour, urea granules, LDPE pellets, limestone powder, sugar, and NPK fertilizer.
06
Total Cost of Ownership Comparison
How to calculate and compare the TCO of each conveying method for your specific application — including energy, maintenance, and product loss.
Who This Is For

Written for working engineers and project teams.

This guide is not a marketing document. It is written for people with a real engineering problem to solve.

Process Engineers
Selecting a conveying system for a new plant or replacement project. Use this decision matrix to arrive at a defensible system selection.
Plant Managers
Experiencing high maintenance costs or product degradation on an existing conveying system. Use this to assess whether the system type matches your material.
Procurement Teams
Evaluating conveying system quotations. Use this to verify that the vendor has selected the right system type for your material.
