In bulk material handling, efficiency and safety go hand in hand. Choosing the right conveyor equipment is critical to keeping operations running smoothly, safely, and cost-effectively. One of the most important tools for making that decision is the CEMA Rating Guide.
The CEMA rating plays a vital role in determining whether a conveyor is suitable for specific applications. In this guide, we’ll explain what CEMA is, break down its classifications, and show how Luff Industries designs conveyor systems that meet or exceed these standards.
What is CEMA? | Conveyor Equipment Manufacturers Association
CEMA stands for the Conveyor Equipment Manufacturers Association, founded in 1933. This trade group sets industry-wide standards for conveyor equipment design, manufacturing, and usage. By establishing clear and concise guidelines, CEMA ensures that conveyor systems are:
- Safe
- Reliable
- Efficient
For operators, understanding and applying the CEMA Rating Guide means choosing conveyor systems that are compatible, durable, and optimized for overall performance.
Understanding CEMA Ratings | Why They Matter
The CEMA Rating Guide is a classification system that helps identify the right conveyor system for specific applications. Ratings are based on load-carrying capacity, belt width, idler spacing, conveyor speed, and the characteristics of the material being transported.
By using these ratings, operators can ensure they select conveyors that are properly matched to their material handling needs – improving safety, efficiency, and long-term reliability.
CEMA Classifications | A to F
CEMA provides six specific classifications, from A through F. Each class is designed for a different capacity level and application:
- CEMA A – Low-capacity, low-speed conveyors with minimal impact loading.
- CEMA B – Low to medium capacity, often used in small quarries or light mining.
- CEMA C – Medium to high capacity, ideal for bulk heavy materials.
- CEMA D – Heavy-duty conveyors designed for abrasive or high-impact materials.
- CEMA E – Extra-heavy-duty conveyors for extreme conditions.
- CEMA F – Highest capacity conveyors for the most demanding applications.
Factors That Determine a CEMA Rating | Key Considerations
Several factors influence the proper CEMA rating for a conveyor system:
- Material type and density
- Conveyor speed
- Belt width and thickness
- Idler spacing
- Lump size of material
Understanding these factors ensures you choose a conveyor system that can handle the load safely while minimizing downtime and wear.
