Material and batch
State what will be mixed and the required amount per batch.
Capacity selection guide
How to choose small concrete mixer capacity
Separate total drum volume from stated mixing capacity, then match the batch requirement to site power, movement and transport conditions.
Direct answer
Use mixing capacity for batch planning when the manufacturer states it.
Drum capacity describes total drum volume. It should not automatically be treated as usable batch output. SHUNGONG currently lists a 112 L mixing capacity for SG140L and 280 L for SG350D. The current verified SG120S data lists 120 L drum capacity but no separate mixing-capacity figure.
- SG120S
- 120 L drum · mixing capacity not separately listed
- SG140L
- 140 L drum · 112 L mixing capacity
- SG350D
- 350 L drum · 280 L mixing capacity

Provide quantity, country, port and any packing requirements.
Capacity questions
Short, citable answers
What is the difference between drum capacity and mixing capacity?
Drum capacity is the total internal volume of the drum. Mixing capacity is the stated working batch volume and is the more useful figure for planning a batch.
Can I calculate SG120S batch output from its 120 L drum capacity?
No. The current verified SG120S data does not list a separate mixing capacity, so its 120 L drum capacity should not be presented as working batch output.
What are the stated mixing capacities of SG140L and SG350D?
SG140L is listed with 112 L mixing capacity. SG350D is listed with 280 L mixing capacity. Final configuration and working conditions still need confirmation.
What information should I provide for model selection?
Provide the material, required batch size, batches per day, worksite power, access conditions, quantity, destination country and destination port.
