Vacuum Hydraulic Lifting Double Shaft Dispersing Mixer

The Double Shaft Mixer is equipped with two mixing systems: an Anchor Agitator with PTFE Scrapers and a High-Speed Disperser. These two agitators operate through a concentric shaft arrangement, allowing different mixing actions to work simultaneously.

The centrally positioned dispersing disc generates strong shear forces at high rotational speeds, helping break down powder particles, accelerate their incorporation into liquids, and reduce agglomeration during processing. Meanwhile, the outer anchor agitator continuously moves the material toward the dispersing zone, maintaining circulation throughout the vessel. Its PTFE scrapers also remove material adhering to the tank's inner walls, helping achieve more uniform mixing and reduce material residue.

Both agitators feature independently adjustable speeds, allowing operators to configure the mixing process according to different material properties and production requirements.

Key Features

• Dual Agitator Configuration: Concentric shaft structure with two independently driven mixing units, combining a high-speed disperser and a low-speed anchor frame agitator equipped with PTFE wall scrapers.

• Hydraulic Lifting System: An oil hydraulic mechanism raises and lowers the mixing assembly, providing convenient positioning for operation and maintenance.

• Variable Speed Control: Frequency converter control enables flexible adjustment of agitator speeds to accommodate different processing requirements.

• Jacketed Mixing Tank: The tank jacket supports the circulation of heating or cooling media for temperature control during production.

• Stainless Steel Construction: Standard wetted parts are manufactured from SS304 stainless steel, with SS316L available as an optional material.

• Vacuum and Inert Gas Capability: The sealed vessel can operate under vacuum conditions or with inert gas protection, depending on process requirements.

• Heating and Cooling Options: Compatible with external heating or chilling systems to regulate material temperature during mixing.

• Floor-Mounted Structure: A floor-standing configuration provides a stable installation for industrial production environments.

Applications

The Double Shaft Mixer is designed for medium- to large-batch manufacturing processes that require material dissolution, mixing, blending, or reaction.

It is suitable for processing a wide range of industrial materials, including putty, paints, printing inks, pigments, gels, and resins. The combination of high-speed dispersion and low-speed anchor mixing makes it particularly suitable for production processes involving materials with different viscosities and mixing characteristics.

Competitive Advantages

1. Enhanced Mixing and Dispersion Performance

The machine combines a centrally located high-speed dispersing impeller with an outer anchor-frame agitator fitted with PTFE scrapers. During operation, the anchor agitator continuously moves materials toward the dispersing disc, while the high-speed unit provides intensive dispersion. The scrapers remove material buildup from the vessel's inner walls, promoting more effective material circulation.

Compared with conventional single-agitator mixers, this dual-system configuration provides more comprehensive mixing action and improves processing efficiency. The jacketed vessel also allows heating or cooling media to circulate around the tank, supporting temperature regulation and more efficient processing, particularly when handling high-viscosity materials.

2. Convenient Operation and Speed Control

The equipment features a digital speed display for monitoring operating conditions. An optional PLC touchscreen control system is available for more centralized operation.

The hydraulic lifting mechanism enables smooth raising and lowering of the mixing assembly through control buttons or the optional touchscreen interface. In addition, the frequency converter allows operators to adjust the agitator speed to match specific material characteristics and production processes.

3. Reliable Construction for Continuous Industrial Use

The Double Shaft Mixer is driven by an industrial three-phase asynchronous motor designed for long-duration operation in manufacturing environments.

SS304 stainless steel is used for standard material-contact components, while SS316L is available as an optional upgrade to meet different material compatibility and production requirements. This robust construction supports reliable equipment operation across a variety of industrial mixing applications.
