JS4000 Concrete Mixer

What is the JS4000 Concrete Mixer?

JS4000 is a large, compulsory, twin-shaft concrete mixer that plays a key role in major construction projects.

• JS: A Chinese pinyin abbreviation that stands for “twin-shaft compulsory mixer.”
• 4000: Indicates its discharge capacity of 4000 liters, which means that each batch can theoretically produce 4 cubic meters (m³) of ready-mixed concrete.

Note:

Simply put, JS4000 is a large concrete mixer capable of producing 4 cubic meters of concrete per batch.

JS4000 Concrete Mixer Specifications

JS4000 Concrete Mixer Features

• Forced Mixing: Using mixing blades fixed on two parallel shafts to apply strong shearing, squeezing, and overturning forces to the materials, resulting in powerful mixing action.
• High Mixing Efficiency and Excellent Quality: Particularly suitable for mixing dry-hard, semi-dry-hard concrete and lightweight aggregate concrete; offers high mixing uniformity and stable concrete quality.
• Twin-Shaft Design: Provides a large mixing range with no dead zones, and offers faster mixing speed compared to single-shaft mixers.
• Robust Structure: To withstand enormous mixing torque and impact loads, the frame, mixing drum, shafts, and blades are all heavy-duty and made from high-quality steel.
• Automated Control: Typically used with PLD series concrete batching machines and a fully automatic computer control system to form an HZS200 concrete batching plant, enabling automated production.

JS4000 Concrete Mixer Applications

The JS4000 belongs to large-scale engineering equipment and is mainly used for:

• Large Water Conservancy and Hydropower Projects: Such as dams and reservoir construction.
• Ready-Mix Concrete Plants: Serving as the core host of HZS200 plants to supply ready-mixed concrete for urban construction.
• Highway and Railway Construction: Such as expressways and high-speed rail projects.
• Ports, Terminals, Bridges, and Other Large Infrastructure.
• Precast Component Factories: Producing large precast concrete components.

Why Choose JS4000?

Outstanding Mixing Performance

• Mixing Quality: Capable of mixing dry-hard, plastic, fluid, lightweight aggregate concrete and various mortars.
• Mixing Uniformity: The double-spiral continuous blade design improves mixing uniformity by 15% compared to traditional shovel-type blades.
• Mixing Efficiency: With a mixing cycle of just 60 seconds, it can produce 200–240 cubic meters of concrete per hour.

Economy and Reliability

• Low Energy Consumption: The compact transmission system saves 10–15% energy compared to similar products.
• Low Noise: The optimized transmission device keeps noise at industry-leading levels, improving the working environment.
• Easy Maintenance: The structure is designed for convenient inspection; key components are easy to replace, reducing maintenance costs.
• Long Service Life: Key components are made of high-quality materials, ensuring a service life of over 10 years and a short return-on-investment period.

JS4000 Concrete Mixer Working Process

In a complete concrete batching plant, the JS4000 working process is as follows:

• Batching: The PLD batching machine weighs sand, gravel, cement, fly ash, and other aggregates and powders according to the mix ratio.
• Lifting/Conveying: The weighed aggregates are transported via belt conveyor or skip hopper to the aggregate hopper above the mixer. Powders and water are added through screw conveyors and pumps.
• Mixing: All materials enter the JS4000 mixing drum; the motor drives the two shafts to rotate in opposite directions, enabling strong mixing through the blades.
• Discharging: After mixing is complete, the pneumatic or hydraulic discharge gate opens to unload the mixed concrete into the waiting concrete mixer truck.
• Cycle: The discharge gate closes and the next mixing cycle begins.

JS4000 Concrete Mixer Advantages

• High Output: Meets the huge concrete demand of large-scale engineering projects.
• Stable Quality: Forced mixing ensures uniformity and high-strength concrete.
• High Reliability: Heavy-duty design with low failure rate; suitable for harsh working conditions.
• High Degree of Automation: Easily integrated into automated batching plants, reducing manual intervention.

JS4000 Concrete Mixer Components

Component	Image	Description
Mixing System		The JS4000 mixing system is made of high-alloy wear-resistant materials, ensuring stable mixing and uniform blending; the multi-layer shaft-end sealing technology effectively prevents slurry leakage, improving production efficiency and extending service life.
Unloading System		The discharging system offers hydraulic, pneumatic, and manual control options; the mechanism is driven by cylinders to achieve fast, stable, and reliable discharge operations.
Water Supply System		The water supply system consists of a motor, pump, throttle valve, cleaning device, and spray pipe; water is delivered through the pump and throttle valve to the spray pipe, and the valve adjusts the water flow to ensure proper concrete consistency.
Lubricating oil pump		The grease pump is equipped with a grease filtering inlet to prevent impurities from entering and affecting the sealing performance, thereby enhancing equipment precision and extending service life.
Electrical System		The electrical system features short-circuit and overload protection, uses insulated panel design, and ensures safe, reliable operation with convenient daily use and maintenance.
Gear Motor		The gear motor reduces output speed while increasing torque; by coordinating motor output with the reduction ratio, it effectively reduces load inertia and ensures smoother, more efficient operation.

JS4000 vs Other Mixer Models

The JS4000 achieves the best balance among capacity, energy consumption, and price, making it an ideal choice for large-scale projects and medium-sized batching plants. It avoids the insufficient capacity of the JS3000 and the high investment burden of the JS5000.

With its 4-cubic-meter capacity, over 200m³/h output, and twin-shaft compulsory mixing technology, the JS4000 concrete mixer has become a core device in modern large-scale construction and batching plants. It not only provides excellent mixing quality and accommodates various mix designs, but also offers low energy consumption, low noise, easy maintenance, and outstanding long-term economic performance.

JS4000 Concrete Mixer Supporting Solutions

As the main host, the JS4000 is typically paired with a series of supporting products to form a complete system (usually an HZS200 batching plant) for efficient operation.

A complete JS4000 batching plant (i.e., HZS200 plant) includes the following core components:

JS4000 Concrete Mixer Notes / Drawbacks

• High Investment Cost: Equipment and supporting batching plant require significant investment.
• High Energy Consumption: Two high-power motors operate simultaneously, consuming large amounts of electricity.
• Large Footprint: Requires a solid concrete foundation and a large installation site.
• Professional Maintenance: Needs a professional maintenance team and sufficient spare parts.

The JS4000 concrete mixer is a typical representative of large, efficient, forced-type mixing equipment. With its strong production capacity and reliable mixing quality, it provides essential support for modern large-scale infrastructure construction.
