300L Vacuum Power Disperser Mixer Machine (QF-300) – Heavy-Duty Dispersion for High-Viscosity Materials

The 300L Vacuum Power Disperser Mixer Machine is a heavy-duty industrial dispersing and mixing system designed for processing high-viscosity pastes, sealants, adhesives, battery materials, and other demanding formulations. This Multi-Functional Vacuum Strong Power Dispersing Mixer combines low-speed stirring with high-speed dispersion under vacuum conditions, delivering efficient and consistent mixing results for manufacturers across multiple industries.

Product Overview

The 300L Vacuum Power Disperser Mixer Machine (QF-300) is a Multi-Functional Vacuum Strong Power Dispersing Mixer manufactured by Wuxi Maxwell Automation Technology Co., Ltd. This equipment is specifically engineered to handle paste-like materials, heavy slurries, and formulations with high solid content that require intense dispersion force.

Unlike standard emulsifying mixers that focus on liquid-liquid emulsification, this Multi-Functional Vacuum Strong Power Dispersing Mixer is optimized for solid-liquid dispersion and paste mixing. The equipment features a dual-motor design: a low-speed stirring system for bulk material turnover and a high-speed dispersing shaft for intense particle size reduction and uniform dispersion. The vacuum system ensures bubble-free processing, which is critical for applications such as battery paste production, sealant manufacturing, and high-quality cosmetic formulations.

The QF-300 is part of Maxwell's QF series of Multi-Functional Vacuum Strong Power Dispersing Mixers, which also includes models such as QF-500, QF-600, QF-800, QF-1000, QF-1100, and QF-5000, offering working volumes from 300L to 5000L.

Working Principle

The QF-300 Multi-Functional Vacuum Strong Power Dispersing Mixer operates on a unique multi-stirrer principle. What sets this dispersion mixer apart is that it includes 3-4 different stirrers within the tank. Of these, one low-speed stirrer rotates on the container axis while the other 2-3 high-speed stirrers rotate at different high speeds about their own axes. This way, materials inside the container undergo strong shear and kneading, completing the mixing process in one complex movement.

The low-speed stirring system, driven by an 11 KW motor at a fixed 33 rpm, provides powerful bulk material turnover, ensuring that all contents in the tank are continuously moving and preventing dead zones. This is particularly important for high-viscosity pastes that would otherwise stick to the tank walls.

Simultaneously, the high-speed dispersion system, driven by a 15 KW motor with variable speed control (0-1450 rpm), creates intense shear forces through the dispersion disc. The high-speed rotation of the disc generates strong centrifugal force, drawing materials into the dispersion zone where particles are subjected to hydraulic shear, impact, and cavitation. This combination of forces effectively breaks down agglomerates and disperses solid particles uniformly throughout the liquid phase.

The vacuum system operates during the entire mixing process, removing trapped air and volatile components. This is essential for applications where air entrapment would compromise product quality.

The hydraulic lifting system allows the mixing head and cover to be raised for easy cleaning, inspection, and material discharge.
