If you’ve searched “concrete mixer” and landed on a wall of product listings with no real explanation of what separates a 350L drum from a 500L drum — or why some mixers cost five times as much as others — this guide is for you.At the same time, welcome to the official CNWH website.
CNWH has been building and exporting concrete mixers from China since 2008. We’ve shipped to Southeast Asia, Africa, the Middle East, and Latin America, so we’ve seen every use case. Below is a no-fluff breakdown of what actually matters when you’re picking a machine.
1. Types of concrete mixers
Not every site needs the same machine. Here’s a quick split:
Tilting Drum Concrete Mixer
- Most common for small to mid projects
- Good for general concrete and mortar
- Easy to maintain, widely serviced
- Typical drum: 350L – 700L
Skip-Hopper Drum Mixer
- High-intensity mixing — used in precast & RMC plants
- Better output consistency
- Higher upfront cost
- Capacity: 150L – 750L
Hand-pushed Mixer
- Light construction, renovation, rural jobs
- Single-phase or three-phase power
- Low noise, low maintenance
- Best for 1–5 m³/day output
Self-loading mixer truck
- Loads, mixes, transports, discharges
- Ideal for remote sites without RMC access
- Diesel-powered, 4WD available
- Capacity: 1.2 – 6.5 m³
2. Drum capacity: don’t over-buy
A common mistake is calculating drum size only by daily concrete volume. You also need to think about batch cycle time, your crew size, and whether you’re mixing by hand or pumping directly into formwork.
Rule of thumb: a 350L drum produces roughly 0.25 m³ of mixed concrete per batch. At 20 batches/hour, that’s around 5 m³/hour — enough for a mid-size house slab pour without waiting.
| Drum capacity | Output per batch | Typical use | Motor (electric) |
|---|---|---|---|
| 180 – 250L | 0.10 – 0.18 m³ | Garden, repair, small masonry | 1.1 – 1.5 kW |
| 300 – 400L | 0.20 – 0.28 m³ | Housing, columns, beams | 2.2 – 3.0 kW |
| 500 – 750L | 0.35 – 0.55 m³ | Roads, bridges, commercial slabs | 4.0 – 7.5 kW |
| 1,000L+ | 0.70 m³+ | Precast yards, batching plants | 11 – 22 kW |
3. Electric vs. diesel concrete mixer
This is the question CNWH gets most often. The honest answer depends entirely on your site conditions, not brand preference.
Electric wins when you have a stable grid connection. Lower noise, zero exhaust, easier maintenance, and significantly lower running cost per hour. Most urban and semi-urban construction sites in Asia and Africa can run a three-phase electric mixer without problems.
Diesel makes sense the moment you’re more than a few hundred meters from grid power — road construction, rural housing programs, mining support, disaster relief. A diesel concrete mixer with a 186F or Loncin engine will run all day in 40°C heat without complaining. CNWH’s diesel drum mixers use Weichai and Yanmar-compatible engines for easy local servicing.
4. Specs buyers always miss
You’d be surprised how often buyers compare drum size and price, then overlook the specs that actually affect job performance:
Mixing blade angle and pitch. Blade geometry determines how well the concrete folds. Cheap mixers use simple straight blades that leave dry pockets. CNWH drums use helical blade design for even distribution without increasing cycle time.
Drum material and thickness. A 4mm manganese steel drum lasts far longer than a 2.5mm mild steel one, especially in abrasive aggregate environments. Always ask for drum plate specs before buying.
Discharge height. If you’re loading a wheelbarrow, 0.8m discharge height is fine. If you need to fill a concrete pump hopper or a truck bed, you want 1.1m or more.
Water supply system. A built-in metered water tank saves time and improves w/c ratio consistency. Not all mixers include this — it’s worth asking about as an option.
After-sales parts availability. A mixer that’s cheap upfront but uses proprietary parts you can’t source locally will cost you more in downtime. CNWH uses standard components (bearings, seals, gearboxes) available in most markets.

Frequently asked questions
What size concrete mixer do I need for a house construction?
For a typical single-family house (slabs, columns, beams), a 350L–500L drum mixer is the most practical choice. You get enough batch volume to keep a crew of 4–6 working continuously without waiting for the next batch. If you have a concrete pump on site, move up to 500L+ to keep the pump fed.
How long does a concrete mixer last?
A quality drum mixer with proper maintenance typically runs 8–15 years. The main wear parts are blades, bearings, and the drum lining. CNWH uses manganese steel drums and sealed bearings to extend service intervals. Replacing blades every 500–800 operating hours is normal in high-abrasion aggregate environments.
What is the difference between a cement mixer and a concrete mixer?
In everyday use, the terms are interchangeable. Technically, a cement mixer refers to a machine used for mixing cement paste or mortar (no coarse aggregate), while a concrete mixer handles the full mix: cement, sand, gravel, and water. Most machines on the market today handle both.
Can I export a concrete mixer from China directly?
Yes. CNWH exports to 60+ countries and handles all documentation including CO, packing list, and CE/ISO certificates where required. We support FOB, CIF, and DAP terms. Most orders ship in 25–40 days. Contact our export team for shipping cost estimates to your port.
What’s the minimum order quantity for CNWH concrete mixers?
MOQ is 1 unit for most models. We also accept mixed-model LCL shipments if you want to test a few different machines. For bulk orders (10+ units), factory pricing and priority production slots are available.
How does a self-loading concrete mixer work?
A self-loading concrete mixer uses a front-mounted hydraulic shovel to scoop raw materials (aggregate, sand) into the rotating drum. Cement and water are added via metered systems. The drum mixes during transit to the pour point, then tilts to discharge. One operator can complete the full load-mix-transport-discharge cycle in about 10–15 minutes per batch.
