High-Efficiency Laboratory Dispersion & Grinding in Malaysia: Exploring the QiWei FS-400D & FS-1100D Frequency Conversion High-Speed Dispersion Grinding Machines
High-Efficiency Laboratory Dispersion & Grinding in Malaysia: Exploring the QiWei FS-400D & FS-1100D Frequency Conversion High-Speed Dispersion Grinding Machines
Achieving uniform particle dispersion, stable emulsions, and fine wet-grinding results is essential across coatings, paints, inks, adhesives, cosmetics, pharmaceuticals, and chemical R&D laboratories in Malaysia.During product formulation and small-batch pilot testing, inconsistent shear forces or inadequate speed control often lead to pigment agglomeration, phase separation, and batch-to-batch quality variations.
The QiWei FS-400D and FS-1100D Frequency Conversion High-Speed Dispersion Grinding Machinesare purpose-built benchtop systems engineered to solve these formulation challenges. Combining variable-frequency high-speed drive technology with interchangeable dispersing impellers and sand-milling discs, these machines deliver intense hydraulic shear and mechanical impact—enabling rapid mixing, de-agglomeration,homogenization, and fine grinding in a single compact unit.
How Frequency Conversion High-Speed Dispersion Works
When formulating liquid-solid suspensions or viscous emulsions, conventional low-speed stirrers merely circulate bulk fluid without breaking down stubborn particle clusters. By contrast, a high-speed frequency-controlled dispersing disc generates extreme rotational tangential velocity. Under powerful centrifugal force,the surrounding fluid undergoes intense hydraulic shear and high-frequency mechanical impact thousands of times per minute.
This concentrated energy zone rapidly tears apart particle agglomerates, wets solid powders into liquid resins or solvents, and produces a smooth, homogeneous dispersion—dramatically shortening formulation development cycles from hours to minutes.
Two Power Configurations to Match Your Formulation Viscosity
QiWei offers two distinct motor power ratings within the series so laboratories and pilot plants can select the exact torque capacity required for their specific fluid viscosity:
1. QiWei FS-400D (400W Motor — Ideal for Low-to-Medium Viscosity Formulations)
Equipped with a responsive 400W variable-frequency motor, the FS-400D is optimized for formulations with viscosities below 10,000 cP. It is an ideal benchtop choice for water-based coatings, inks, dyes, personal care emulsions, agrochemical suspensions, and general chemical R&D labs seeking precise speed control and quiet, reliable daily operation.
2. QiWei FS-1100D (1.1kW Motor — Built for Higher-Viscosity & Heavy-Duty Dispersion)
Featuring an upgraded 1.1kW high-torque motor, the FS-1100D handles thicker, more demanding formulations with viscosities up to 15,000 cP. It excels in heavy-duty pigment pastes, high-solid industrial coatings, resin dispersions, battery slurry R&D, and adhesives where sustained high shear under load is critical.
Key Engineering & Operational Highlights
1. Wide Stepless Speed Range (100 – 8,000 rpm) with Digital Display Control
Both models feature an external digital display controller that allows operators to smoothly adjust rotational speed from a gentle 100 rpm (for initial powder incorporation without splashing) up to an intense 8,000 rpm for high-shear dispersion and grinding. An optional timing control instrument is also available for automated,repeatable batch runs.
2. Dual Functionality: Stirring Dispersion & Sand Milling
Supplied with both stirring dispersion impellers (50 mm and 60 mm diameter) and a dedicated sand mill disc (60 mm diameter), the unit transitions effortlessly between high-speed mixing/dispersing and bead/sand wet-grinding—giving formulators maximum versatility on one machine.
3. Jacketed / Clamped 1.2L Processing Vessel & Heavy-Duty 40 kg Frame
The included 1.2-liter ingredient vessel locks securely onto the heavy-duty base clamps to prevent shifting at maximum speed. With a solid 40 kg net weight and rigid vertical column (450 × 400 × 800 mm overall dimensions), the machine minimizes vibration and ensures mechanical stability even during sustained 8,000 rpm operation.
