Where this guide applies
This guide is intended for coal mines, coal preparation plants, coal handling terminals, EPC teams, and maintenance buyers comparing equipment or spare parts for practical industrial service. It focuses on how the equipment works in a complete coal process rather than as a stand-alone catalog item.
Key specifications to compare
Buyers should compare capacity, feed size, moisture, abrasiveness, installation environment, available power, certification requirements, maintenance access, spare parts availability, and compatibility with upstream and downstream equipment. For coal projects, application context is often more important than nominal equipment size.
Common selection mistakes
Common mistakes include quoting only the equipment name without duty data, ignoring coal moisture and fines content, overlooking dust and spillage controls, underestimating wear parts consumption, and buying equipment that does not match the site voltage, safety standard, or maintenance capability.
RFQ information to prepare
A useful RFQ should include material handled, capacity, particle size distribution, moisture level, operating hours, installation location, existing equipment interfaces, drawings or photos, and required standards. The more complete the process information, the more accurate the supplier response will be.
How to compare supplier offers
Do not compare only purchase price. Compare total cost of ownership, including energy use, wear part life, downtime risk, lead time for spares, maintenance access, and whether the supplier has understood the process duty. A higher priced option can be cheaper if it reduces shutdown frequency.
