Product Detail

This twin shaft compulsory mixer JS 750 delivers premium quality mixing for construction projects. It ensures uniform and efficient blending of concrete, dry materials, and aggregates. Ideal for brick making, highways, bridges, water conservancy, and docks, it handles both industrial and civil applications. The forced mixing action guarantees consistency, durability, and high productivity. Easy to operate and maintain, it reduces cycle time while improving output quality.
The JS 750 twin-shaft compulsory mixer ensures high-efficiency mixing for medium and small precast component factories. Its dual-shaft design creates a powerful counter-current mixing action, delivering uniform concrete in short cycle times. The unit handles dry, semi-dry, and plastic concrete mixes with ease. A durable discharge door and wear-resistant liners reduce maintenance needs. Compact structure allows simple installation and integration into batching plants.
This JS 750 mixer adapts well to various construction projects. As a standalone unit, it suits medium-scale concrete production. Combined with a PL1200 batcher, it forms a simple, mobile plant for road or building sites. As the main unit of an HZS250 plant, it supports large-scale industrial or infrastructure projects. Its twin-shaft compulsory design ensures high mixing efficiency and uniformity, handling dry, plastic, or semi-dry concrete.

Product Display

This JS 750 compulsory mixer is well suited for construction projects requiring consistent concrete quality. Its twin horizontal shafts rotate oppositely at equal speeds, driven by a motor through synchronous gears. This design delivers stable, uniform mixing even for dry or harsh mixes. The mixer handles up to 750 liters per batch, ideal for medium-to-large sites. Reliable gear synchronization reduces maintenance and supports continuous operation, meeting the demands of precast, road, or dam projects.

Professional Shipping

The JS 750 mixer’s specially angled blades create a dual-action mix, ideal for construction projects. By throwing material toward the cylinder center, they form a “boiling” convection layer for fast, homogeneous blending. Simultaneously, the blades push material from one end to the other, enabling continuous flow. This design suits large-scale applications like precast concrete or road works, reducing cycle times while ensuring uniform quality, even with stiff or dry mixes.

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.
