JS1500 Concrete Mixer

What Is the JS1500 Concrete Mixer?

The JS1500 concrete mixer is a high-efficiency twin-shaft compulsory mixer. With its efficient mixing, wide adaptability, and modular design, it is widely used in various construction projects and precast component factories.

The JS1500 concrete mixer can mix a variety of concrete types: dry hard concrete, plastic concrete, flowable concrete, lightweight aggregate concrete, and various mortars.

The JS1500 concrete mixer is commonly used in concrete batching plants, especially suitable for large or medium-sized construction projects (bridges, roads, precast component factories).

• If you need large-scale production with high concrete quality consistency, the JS1500 is a good choice as it meets industrial-grade standards.
• If your construction site is smaller or requires high mobility, the JS1500 may be too large, and you might consider a smaller mixer or a mobile concrete mixing system.

JS1500 Concrete Mixer Specifications

JS1500 Concrete Mixer Features

• High mixing uniformity: Twin-shaft design with multiple blades achieves three-dimensional mixing for uniform results.
• High efficiency: Short cycle time, fast discharge, capable of efficient concrete production (especially suitable for precast factories and large projects).
• Long wear part life: Mixing blades and arms are usually made of high-chromium cast iron and heat-treated for enhanced wear resistance.
• Reasonable structure: Mature sealing, lubrication, and hydraulic discharge door systems; includes automatic lubrication and adjustable discharge door angle.
• Wide application: Can mix plastic concrete, dry hard concrete, lightweight aggregate concrete, and various mortars.
• Flexible configuration: Can serve as the main mixer for concrete batching plants (e.g., HZS75, HZS90) or be used as a standalone unit.

JS1500 Concrete Mixer Structure

Mixing System:

• Mixing drum: The core container, equipped with two parallel mixing shafts.
• Mixing shafts: Each shaft has multiple blades arranged at specific angles. The two shafts rotate in opposite directions to shear, squeeze, and overturn materials for powerful mixing.
• Liners: Installed on the inner wall of the drum to protect it from wear and are replaceable.

Drive System:

Composed of a motor, reducer, and open gears, transferring power to both mixing shafts to ensure synchronized counter-rotation.

Feeding System:

Usually paired with a PLD4800 batching machine. Aggregates (sand, gravel) are measured by the batching machine and lifted to the top of the mixer via a hoisting mechanism and feeding hopper along a track.

Discharging System:

• Hydraulic discharge: Most common method. The bottom discharge door is driven by hydraulic cylinders, allowing fast and leak-free discharge.
• Pneumatic discharge: Used in a few models, controlled by cylinders.

Lubrication System:

Large mixers are usually equipped with an automatic centralized lubrication system, providing timed and measured lubrication to key points such as shaft ends, reducing maintenance work and improving reliability.

Water Supply System:

Includes water tank, pump (or pneumatic flow meter), and flow meter to accurately control the water volume for each mixing cycle.

Control System:

Integrated with the batching plant control system to receive commands and control mixer start, stop, and discharge operations.

JS1500 Concrete Mixer Advantages

• High mixing quality: Twin-shaft compulsory mixing provides good concrete uniformity, suitable for high-standard projects.
• High production efficiency: Short mixing cycle and large discharge volume meet the needs of continuous, large-scale production.
• Strong reliability: Robust structure, with reliable design of key components such as reducers and shaft seals.
• Fast and thorough discharge: Hydraulic large-opening door allows fast discharge with low residual rate.
• Easy maintenance: Replaceable liners and blades, with centralized lubrication reducing daily maintenance workload.

JS1500 Concrete Mixer Applications

• Precast component factories (production of precast concrete)
• Large or medium concrete batching plants (HZS series)
• Roads, bridges, water conservancy, ports, and other infrastructure projects
• Projects with high concrete quality consistency requirements

• HZS75/HZS90 commercial concrete batching plants: as the core mixer.
• Large-scale water conservancy, power, highway, bridge, and port construction: as on-site mixing equipment.
• Precast component factories: providing concrete for component production.

JS1500 Concrete Mixer Supporting Equipment

• Batching machine: PLD4800 four-compartment or three-compartment batching machine.
• Cement silo: Typically equipped with 2–4 silos of 100T or 150T capacity.
• Screw conveyor: Used to transfer cement, fly ash, and other powder materials to the mixer.
• Control room: Centrally controls the entire mixing system.
• Dust removal system: Ensures environmentally friendly production.

JS1500 Concrete Mixer Purchasing Tips

• Confirm production rate: Choose the appropriate capacity (m³/h) based on your project scale.
• Motor/power configuration: Check whether the motor power of the mixer and lifting device meets your power supply and efficiency requirements.
• Sealing and wear parts: Inquire about shaft-end sealing solutions and blade materials (good wear resistance affects maintenance costs).
• Discharge height: If using cranes or trucks to receive concrete, the discharge height must match.
• Maintenance and lubrication system: It is recommended to choose a model with automatic lubrication and good sealing structure to reduce failures.
• After-sales and spare parts: Confirm whether the manufacturer provides spare parts (blades, liners) and after-sales support.
• Environmental requirements: Modern batching plants must meet higher environmental standards; consider enclosed design, efficient dust removal, and wastewater recycling systems.

The JS1500 concrete mixer is a mature, stable-performing, and widely applicable mid-sized mixer, making it an ideal choice for modern concrete production lines.
