The JS Series twin shaft compulsory mixer features dual-shaft counter-rotation, where two horizontally parallel shafts are driven by a motor and rotate in opposite directions at identical speeds through synchronous gears. This design ensures stable and consistent stirring action across the entire mixing chamber. The opposing rotation creates intense material flow, forcing aggregates, cement, and water to interact thoroughly for complete homogenization. No dead zones remain, and every particle receives equal mixing energy.

Product Detail
Product Display
The JS Series twin-shaft mixer’s core feature is that two bladed mixing shafts rotate synchronously in opposite directions within a horizontal cylinder. This configuration forces convection and shearing of the material rather than relying on free fall. The counter-rotating action creates intense mechanical agitation that thoroughly breaks down agglomerates and coats every particle with cement paste. This forced mixing principle delivers superior homogenization in shorter cycle times compared to gravity-based mixers. The result is consistent concrete quality with uniform strength and workability, making the mixer essential for precast and ready-mix applications requiring reliable batch-to-batch performance.
Exhibition Experience
The JS Series twin-shaft compulsory mixer delivers high efficiency and excellent uniformity through intense convection and shearing action on materials. This powerful mixing process typically completes a full batch in only forty to sixty seconds, significantly reducing cycle times compared to conventional mixers. The rapid yet thorough blending ensures every particle is uniformly coated and distributed, producing consistent concrete quality for every batch. This fast mixing capability increases overall production output, lowers energy consumption per batch, and supports continuous operation in commercial plants, precast yards, and construction sites where speed and reliability are essential.
| 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. |
