The sword-like structure of the JS Series twin shaft mixer enhances cutting action and material flow. It generates high shear force to break down agglomerates and ensure uniform cement paste consistency. This design accelerates mixing cycles, reduces dead zones, and improves discharge efficiency. By creating intense turbulence and particle dispersion, it supports rapid, homogeneous batches for demanding applications. The structure also minimizes residue buildup, lowering cleaning time and maintenance costs while extending component life.

Product Detail

The JS Series mixer features dual-shaft counter-rotation, where two horizontally placed shafts rotate in opposite directions. This creates a vigorous, multi-directional mixing motion that forces materials to cross and collide repeatedly. The result is rapid, uniform cement blending without dead zones or segregation. This high-efficiency mechanism significantly reduces mixing cycles while delivering consistent concrete quality. Ideal for demanding construction sites, the twin-shaft design also minimizes material buildup on blades, lowering maintenance needs and ensuring durable, reliable performance for large-scale continuous operation.
.The JS Series high efficiency automatic twin shaft compulsory cement mixer features two horizontally parallel shafts driven by a single motor. Through a pair of synchronous gears, the shafts rotate in opposite directions at identical speed. This balanced counter-rotation ensures that the mixing tools continuously intersect, creating a fluidized vortex zone. As a result, the mixer delivers exceptionally stable and uniform stirring action, eliminating material segregation and improving batch consistency. Ideal for demanding concrete production, it guarantees reliable performance and high homogeneity with every cycle.
The JS Series mixer uses dual opposed rotating shafts with layered spiral blades to create a forced agitation zone. This design eliminates dead corners, ensuring every particle of cement, sand, and aggregate is uniformly blended within 30–40 seconds. The blade angle and speed generate high shear force, rapidly breaking down agglomerates for consistent micro-mortar distribution. Ideal for high-strength concrete production, this mechanical agitation system reduces mix time compared to gravity mixers, improves batch uniformity, and maintains stable output quality in precast or construction site applications.

Product Display

The JS Series twin shaft compulsory mixer features segmented functional design for enhanced maintainability and longevity. Key components are divided into independent modules, including mixing arms, liners, and discharge mechanisms. This allows quick replacement of worn sections without dismantling the entire machine. Each segment is engineered for specific force zones, optimizing mixing uniformity and reducing energy loss. Separate lubrication and inspection ports further simplify routine checks.

Customers Access

The JS Series twin shaft mixer features high-end axial zoning for optimized concrete preparation. The front section employs spiral blades to enable rapid material conveying, reducing feed time. The middle section integrates large-angle blades that generate vigorous, high-intensity mixing for uniform paste consistency. This sequential design eliminates material buildup and ensures thorough dispersion of binders and aggregates, boosting overall efficiency for demanding construction projects.

FAQ

1. How uniform is the mix, and what materials can it handle?

The twin shaft design ensures a high mixing uniformity coefficient above 95% within 30 to 60 seconds. It handles dry concrete, semi-dry concrete, and plastic concrete, as well as lightweight aggregate mixes. It also works well with mortar and some fibrous materials.

2. Can this mixer be integrated with batching plants and automation systems?

Yes.The JS Series comes with a control interface ready for PLC integration. It supports automatic feeding, water metering, and discharge cycle control. We provide wiring diagrams and protocol support (Modbus RTU or Profibus optional) to connect with most existing batching plant systems.

3. How do you maintain the shaft seals to prevent concrete from leaking into the bearings?

The JS Series features a multi-layer seal system including an oil-lubricated double lip seal and an air purge cavity. This prevents slurry ingress. Daily visual checks and greasing every 40 hours of operation are recommended. The bearing housing is separate from the mixing chamber, so if a seal fails, the bearing is not instantly damaged.

4. What is the power requirement and energy consumption per batch?

Power varies from 25.3 kW for the JS500 up to 38.8 kW for the JS1500. Energy consumption per cubic meter of finished concrete averages 1.2 to 1.8 kWh, depending on material consistency.

5.What is the wear life of the lining plates and mixing blades？

Our high standard version uses alloy steel liners and blades. Under normal operating conditions with abrasive materials like standard concrete, the lining plates typically last 5,000 to 8,000 hours, and blades last 4,000 to 6,000 hours. For highly abrasive mixes, we offer extended wear parts.
