Quick Takeaways
- Rock hardness and wear strategy can change CAPEX and OPEX significantly.
- Civil works, electrical distribution, and steel structure are often under-budgeted.
- Automation level and spare package can shift total investment by 15-30%.
- Use a scope-normalized RFQ matrix before comparing supplier prices.
What drives cost the most on a 300 t/h project
The strongest cost drivers are ore hardness, product split, and circuit complexity (for example adding shaping or washing stages). Civil and electrical balance-of-plant scope is often the hidden part that creates the biggest budget gap after purchase.
Three common scope levels buyers compare
Most quotes fall into three levels: machine-only, mechanical package, and full line delivery. Price differences can look huge until you normalize foundation, steel, electrical, controls, commissioning, and first-year critical spares.
How to avoid low-price traps
Ask every supplier to quote against the same feed assumptions, operating hours, and delivered boundaries. Then compare cost per delivered ton and expected wear budget, not only ex-works equipment price.
FAQ
Why can one 300 t/h quote be much lower than another?
Usually because scope is not equivalent. Lower quotes often exclude electrical/control systems, structural steel, installation support, or critical spare parts.
Should I buy exactly 300 t/h nameplate capacity?
Usually no. Keep around 20-30% design margin to absorb feed variation, wear progression, and seasonal instability.
What information should I prepare before requesting a quote?
Prepare max feed size, rock type/hardness, target products, operating hours, site power standard, and required automation boundary. This is the minimum set for comparable proposals.
