Application guide / generalized scenario
A practical route guide for Brazilian river-pebble projects focused on manufactured sand quality, wash-loop balance, and saleable fines retention.

01 / Reference conditions
For this Brazil scenario, treat saleable fine loss in the wash loop as a variable to measure rather than assuming crusher throughput represents commercial yield.
This guide compares three routes for 100-260 TPH plants targeting concrete-grade manufactured sand.
02 / Selection logic
01
Condition
Main revenue depends on 0-5 mm saleable fraction
Recommendation
Treat washing and recirculation as core design, not add-on
Operating reason
Fine loss can occur in washing and classification, so measure the mass balance after crushing as well as crusher output.
02
Condition
Clay contamination is low but moisture swings are high
Recommendation
Use balanced shaping plus controlled wash strategy
Operating reason
Over-washing clean feed can dump profitable fines.
03
Condition
Project requires premium shape index and strict cleanliness
Recommendation
Adopt closed-loop premium route with tighter control
Operating reason
Premium contracts justify additional control complexity.

05 / Comparison matrix
Swipe or scroll horizontally to compare all three routes.
| Metric | Basic | Balanced | Premium |
|---|---|---|---|
| Planning condition | Local commodity sand | Mixed quality demand | Premium concrete contracts |
| Fine-loss control | Basic | Good | High (validate) |
| Shape consistency | Medium | High | Very high |
| Main risk | Revenue loss in wash overflow | Tuning drift in recirculation | Complexity without data discipline |
| Water system demand | Low-medium | Medium | Medium-high |
06 / Operating context
If crusher output is optimized without a wash-loop mass balance, saleable yield and fine loss remain unverified.
Compare crusher output with final saleable sand on a defined reporting interval to identify where the material balance changes.
Ask vendors to report expected saleable 0-5 mm yield, not only plant throughput. Throughput alone can hide poor economics.
Require a water-and-fines mass balance sheet in technical proposal deliverables.
07 / Supplier brief
08 / Project handoff
Replace assumptions with data
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.
