JS500 Concrete Mixer

JS500 is a very classic and commonly used piece of construction machinery, belonging to the twin-shaft compulsory concrete mixer. The JS500 mixer features stable performance and mature technology, making it a dominant mixing unit in small and medium-sized concrete production.

The number "500" in JS500 concrete mixer indicates a discharge capacity of 500 L (0.5 cubic meters) per batch, making it a commonly used medium-sized mixing device in construction projects.

With its high efficiency, stability, and versatility, the JS500 concrete mixer is an ideal choice for small and medium-sized construction projects and precast component production. It not only delivers excellent mixing quality but also offers good reliability and cost-effectiveness to meet diverse construction needs. If a larger output is required, other models in the JS series can be considered. If the budget is limited and the output requirement is not high, the JS350 is also a good alternative.

JS500 Concrete Mixer Specifications

JS500 Concrete Mixer Features

Forced Mixing:

Through two counter-rotating mixing shafts and the staggered mixing blades arranged on the shafts, the materials are subjected to strong shearing, squeezing, and overturning.

Advantage: Strong mixing action, high efficiency, and excellent mixing quality (high homogeneity), especially suitable for mixing dry-hard concrete, semi-dry-hard concrete, various mortars, and lightweight concrete.

Twin-Shaft Structure:

Compact structure and fast mixing speed; a mixing cycle can typically be completed within 30–45 seconds.

Fast and clean discharge with almost no residue.

Wide Application Range:

An ideal choice for small and medium-sized construction projects, bridges, roads, and precast component factories.

High Reliability:

Uses mature mechanical or hydraulic transmission technology; robust structure, good durability, and easy maintenance.

Typical Equipment Configuration Scheme for JS500 Mixer

JS500 is usually not used as a standalone machine but as the core part of a concrete batching plant or mixing station. According to the level of automation, there are mainly two configurations:

HZS25 Concrete Batching Plant

This is the most classic configuration for JS500. In the model HZS25, the number “25” represents its theoretical production capacity of 25 m³/h.

Main components:

• JS500 mixing host: the core component.
• PLD800 concrete batching machine: automatically measures sand, stone, cement, and other materials, and conveys them to the mixer.
• Screw conveyor: used for conveying cement/fly ash.
• Cement silo: used for cement storage.
• Control system: manual, semi-automatic, or fully automatic control.

Standalone Use (less common)

Requires manual feeding or a small loader; labor-intensive and low production efficiency; mainly used for temporary or very small-scale projects.

JS500 Concrete Mixer Advantages and Disadvantages

Advantages of the JS500 Concrete Mixer

• Good mixing quality: forced mixing ensures concrete homogeneity and strength.
• High efficiency: short mixing cycle and fast discharge.
• Strong adaptability: capable of mixing various concrete and mortar types and proportions.
• Mature market: proven technology, easily available spare parts, and convenient maintenance.

Disadvantages of the JS500 Concrete Mixer

• Higher energy consumption: compared with drum-type mixers, it requires more power.
• Wear on liners and blades: due to forced mixing, wear parts need regular inspection and replacement.
• Initial investment: as part of a batching plant, the overall investment is higher than a single drum mixer.

JS500 Concrete Mixer Working Principle

• Two horizontally arranged mixing shafts rotate in opposite directions, with spiral mixing blades and scrapers mounted on the shafts.
• During mixing, materials are forced to convect, shear, and tumble under the strong action of the blades, achieving rapid and uniform mixing.
• The mixing efficiency is far higher than that of self-falling mixers, especially suitable for dry-hard concrete and lightweight aggregate concrete.

JS500 Concrete Mixer Applications

• Small and medium-sized commercial concrete plants: supplying ready-mix concrete for urban construction.
• Precast component factories: producing cement pipes, cement bricks, precast stairs, etc.
• Highway, railway, and other infrastructure construction: used for small bridges, retaining slopes, and similar projects.
• Rural self-built houses and small construction sites: when configured as a simple batching plant, it can fully meet concrete needs.

JS500 Concrete Mixer Purchasing Suggestions

If you are considering purchasing a JS500 mixer or a batching plant that includes it, please note:

• Based on production needs: JS500 is suitable for small and medium-sized projects; if daily production exceeds 500 m³, consider JS750 or larger models.
• Consider compatibility: if forming a batching plant, ensure compatibility with PLD batching machines.
• After-sales service: prioritize suppliers offering installation, commissioning, operator training, and timely maintenance services.
