What Are The Concrete Mixer Types?

Concrete mixers are primarily categorized into three types: free-fall type, forced type and continuous type. Core models boast a mixing capacity of 350L or more and are suitable for applications such as construction projects and precast component plants.

The following is a detailed description of the specific types of concrete mixer and typical models:
1. Free-fall Concrete Mixer
The rotating drum drives the blades to lift the material, and gravity achieves mixing. This type is suitable for plastic concrete.
- Conical Reversing Discharge (JZC Series)
Working Principle: The drum rotates forward for mixing and reverses for discharging. The double-cone structure enhances axial material movement.
Representative Models:
JZC500: 500L discharge capacity, 800L feed capacity, 14-18m³/h productivity, equipped with tires for mobility, and a maximum towing speed of 20km/h.
JZC750: 750L discharge capacity, fixed installation, suitable for simple concrete mixing plants in conjunction with a batching machine. Maximum aggregate size is 80mm. Features: Simple structure, low maintenance, suitable for small and medium-sized projects, but mixing efficiency is lower than forced mixers.

2. Forced Concrete Mixer
Uses high-speed rotating blades to forcibly shear the material. Suitable for dry, hard, high-strength concrete and special materials.
- Twin-Shaft Forced Mixer (JS Series)
Working Principle: Two horizontal shafts rotate in opposite directions, with cross-arranged blades, achieving three-dimensional mixing.
Representative Models:
JS500: 500L discharge capacity, theoretical output of 25m³/h, can be used in an HZS25 concrete mixing plant with a mixing time of only 60 seconds.
JS750: 750L discharge capacity, 1200L feed capacity, equipped with a conical agitator disc, suitable for 35-inch concrete mixing plants, with a power of 30kW.
Sicoma Twin-Shaft Mixer: The 2.5m³ model has a feed capacity of 3750L and utilizes multi-stage sealing technology to prevent slurry leakage. Suitable for large commercial concrete plants. Features: High mixing quality and high efficiency. This is the current mainstream model, widely used in highway, bridge, and other projects.

- Single horizontal shaft forced concrete mixer (JDC Series)
Working Principle: A single-shaft spiral blade propels the material axially, while a scraper prevents sticking to the wall.
Representative Models:
JDC500: Discharge capacity 500L, feed capacity 800L, productivity 25-30m³/h, mechanical door unloading to avoid hydraulic system failure.
JDC350: Discharge capacity 350L (near critical value), suitable for lightweight aggregate concrete and mortar, with a towing speed of 15km/h.
Features: Compact structure, low energy consumption, commonly used in small and medium-sized precast component plants.
- Vertical shaft planetary concrete mixer (CMP/DMP Series)
Working Principle: The mixing shaft both orbits and rotates, and the blades shear the material at multiple angles, achieving a mixing uniformity exceeding 95%.
Representative Models:
CMP500: 500L discharge capacity, 18.5kW power, 180° reusable blades, suitable for cement pipe and permeable brick production.
DMP1000: 1000L discharge capacity, suitable for medium- and large-scale production lines, capable of mixing fiber-reinforced concrete and high-grade concrete.
Features: High mixing intensity, suitable for complex materials such as UHPC (ultra-high performance concrete), but equipment cost is relatively high.

- Vertical shaft vortex mixer (JW Series)
Working Principle: A vertical shaft drives the vortex blades to rotate, creating a strong vortex mixing process.
Representative Models:
JW500: 500L discharge capacity, 800L feed capacity, equipped with an automatic water supply system, suitable for precast plants and unfired brick production lines.
Features: Simple structure, easy operation, commonly used on small and medium-sized construction sites.

3. Continuous Concrete Mixer
Capable of continuous feeding and discharging, suitable for large-scale continuous production, commonly found in large-scale batching plants.
- Single-Shaft Continuous Mixer (WAH Series)
Working Principle: A horizontal single-shaft screw propels the material while simultaneously spraying water for mixing. With a processing capacity of 2-1000 m³/h and a maximum capacity of 25,000 L, suitable for mixing dry materials with liquids.
- Dual-Shaft Continuous Mixer (SL Series)
Representative Model: SL20B, with a production rate of 20 m³/h, a discharge height of 1100 mm, and equipped with remote control and mobile wheels, suitable for on-site mixing.
Features: Extremely high production capacity, but the equipment is large and requires an automated control system.

4. Mobile and Stationary Concrete Mixers
- Mobile concrete mixer:
JZC500: A tire-mounted design allows for easy towing and is suitable for multi-site movement.
Continuous Mobile Mixer: For example, the 2.4-cubic-meter model integrates mixing and transport functions, has a discharge capacity of 2400 L, and a maximum speed of 30 km/h.
- Stationary concrete mixer:
JS2000: 2000L discharge capacity, dual motor drive, for 120 concrete mixing plants, 1500mm discharge height.
Large Twin-Shaft Mixer: Models with a rated capacity of 4.5m³ offer a 6750L discharge capacity and utilize an intelligent monitoring system to ensure stable operation.

Concrete mixer types selection recommendations
- Project Scale:
Small and medium-sized projects (such as rural infrastructure): Prefer the JZC500 mobile mixer or the JS500 forced-type concrete mixer for flexibility and efficiency.
Large commercial concrete plants: Choose a twin-shaft JS1500 or higher model or a continuous mixer, compatible with automated production lines.
- Concrete Type:
Dry hard concrete: Forced twin-shaft or planetary concrete mixers.
Plastic concrete: Free-fall JZC series mixers or single-shaft JDC mixers. Special Requirements:
High-grade concrete (e.g., C60 and above): The vertical-shaft planetary mixer offers superior mixing homogeneity.
Environmental Requirements: A continuous mixer with a dust recovery system reduces pollution.

Types of concrete mixers must strictly comply with GB/T 9142 standards, such as discharge time ≤ 15 seconds and residual volume ≤ 5%. When selecting a mixer, consider production volume, budget, and ease of maintenance. Brands such as Haomei Machinery are preferred for their reliability and after-sales service.
