Vietnam Granite Aggregate: Choosing a 180-320 TPH Line for Expressway Supply

A practical route guide for Vietnam granite projects supplying expressway and ready-mix demand under rainy-season feed variability.

Published November 21, 2025 · Updated July 11, 2026 · 9 min read

Reference scenario
Vietnam
Material
Granite for road and concrete aggregate
Design objective
Stable 5-10-20 mm output for expressway and ready-mix contracts

01 / Reference conditions

Scenario overview

For this Vietnam scenario, assume rainy-season feed may add fines and sticky contamination. Validate whether dry-condition settings still hold the target product window.

This guide compares three 180-320 TPH layouts that prioritize dispatch consistency and spec compliance over headline capacity.

02 / Selection logic

Initial decision framework

01

Condition

Project mix is heavy on expressway base and concrete aggregate

Recommendation

Use staged reduction with dedicated shaping duty

Operating reason

Holding shape and gradation together is easier when reduction and shaping roles are separated.

02

Condition

Rainy season causes frequent screen overload and recirculation spikes

Recommendation

Choose route with stronger screening margin and conservative setpoints

Operating reason

Aggressive settings on wet feed can destabilize throughput; confirm with a defined wet-feed test case.

03

Condition

Dispatch windows and rejection penalties are contractually defined

Recommendation

Adopt contract-grade route with tighter control loop

Operating reason

If penalties are tied to missed dispatch or rejected product, uptime and repeatable quality may carry more value than peak output.

03 / Required data

Inputs you must lock before model selection

  1. 01Customer demand split between base, 10 mm, and 20 mm products.
  2. 02Rainy-season contamination profile by quarry face.
  3. 03Historical recirculation load at peak wet weeks.
  4. 04Spec rejection history by product size class.
  5. 05Available maintenance hours during high-demand season.

04 / Process alternatives

Recommended process lines

Route 01

Starter quarry route

Capacity
180-230 TPH
Feed
Granite feed up to 700 mm
Target output
General aggregate mix
Setup
PE Jaw -> PY Cone -> screen

Why this route works

  • Fast to commission for expanding quarries.
  • Lower control complexity for startup teams.
  • Solid baseline when spec pressure is moderate.

Route 02

Balanced rainy-season route

Capacity
220-290 TPH
Feed
Mixed granite with seasonal fines
Target output
Stable 5-10-20 mm products
Setup
PE Jaw -> PY Cone -> PF Impact shaping -> screen

Why this route works

  • Better shape and gradation control in wet weeks.
  • More stable under variable feed contamination.
  • Good fit for multi-project dispatch demand.

Route 03

Contract-grade route

Capacity
280-320 TPH
Feed
Large granite projects with strict QA auditing
Target output
Tight gradation and low rejection
Setup
PE Jaw -> dual PY Cone -> PF Impact trim -> multi-deck screen

Why this route works

  • Designed for stronger product-consistency control, subject to validation.
  • Supports projects with quality-linked penalties.
  • Keeps headroom for volume growth without redesign.

06 / Operating context

Operating notes

01

Rainy-Season Playbook Beats Emergency Adjustments

Define a wet-season parameter window before using the route. Without trigger criteria, ad hoc tuning cannot be evaluated consistently.

A two-mode operating pack with explicit triggers and shift-handover checks provides a repeatable basis for validation.

  • Prepare dry and wet operation packs before rainy months.
  • Track contamination source by bench and shift.
  • Review shape index and gradation as one KPI set.
  • Escalate rising rejection trend as process alarm.
02

How to Keep Supplier Quotes Comparable

Ask all bidders to quote against one identical rainy-season scenario. Without shared assumptions, paper comparisons are misleading.

Require a settings playbook for dry and wet modes in the technical deliverables.

07 / Supplier brief

RFQ checklist before you contact suppliers

  1. 01Seasonal feed contamination assumptions and data source.
  2. 02Product spec targets by size class and customer.
  3. 03Dry/wet operation setpoint strategy.
  4. 04Expected recirculation range under wet feed.
  5. 05Spare and liner plan for peak season.
  6. 06Acceptance test including rainy-season scenario.

08 / Project handoff

Related equipment and next step

Replace assumptions with data

Request a model recommendation for your actual duty.

Share the feed and product conditions that define the process. The guide provides a comparison frame; final equipment sizing still requires a project-specific check.
