High Viscosity Agitator Bead Mill WMS60 60L 45kW For Southeast Asia Paint Grinding

The WMS60 agitator bead mill is a 60-litre horizontal wet grinding machine built for coating factories in Vietnam, Indonesia, Thailand, Malaysia and the Philippines that mill high-viscosity solvent-based and water-based paints in repeatable batches. A 45kW main motor drives a stack of slotted agitator discs that transfer kinetic energy to the grinding media, converting it into intense shear, collision and friction between beads, so pigment agglomerates break down quickly and the product leaves the chamber at a controlled fineness of 20 microns or finer. Production capacity ranges from 100 to 900 kg/h depending on formulation and target fineness, which suits both continuous line feeding and batch circulation through a let-down tank. The grinding chamber, shaft and discs are machined from SS304 and wear-resistant alloy steel, and the seal package uses a double-end mechanical seal with a flushing chamber, so solvent loss, air ingress and leakage stay under control during long runs in a humid tropical workshop.

• Agitator Bead Mill Grinding Principle: rotating slotted discs agitate the bead charge inside a horizontal chamber, so energy is transferred to the media rather than to the chamber wall, giving efficient dispersion at moderate tip speed
• High-Viscosity Capability: the chamber accepts material up to 15 Pa.s, so thickened primer, putty paste and high-PVC wood coating can be milled without pre-dilution and without stalling the agitator
• Forced Spiral Cooling: a spiral guide groove in the cylinder wall directs cooling water along the full grinding length, removing heat before it changes viscosity, gloss or colour strength
• Double-End Mechanical Seal: the seal face runs in a flushed chamber with a low-pressure barrier fluid, keeping leakage minimal even after thousands of operating hours
• Slotted Wear-Resistant Discs: multiple slots and contours create local turbulence that accelerates media collision while the hardened alloy surface resists grooving in abrasive pigment systems
• Repeatable Fineness Control: grinding time, media size and flow rate can be tuned per formulation, giving the same Hegman reading batch after batch for colour matching work
• Service-Friendly Layout: the chamber cover, seal cartridge and screen are accessible from the front of the frame, so routine inspection fits into a normal shift change rather than a full production stop

Typical installations are architectural paint lines, wood coating plants and pigment paste departments that supply local construction and furniture markets across Southeast Asia. The agitator bead mill handles solvent-based alkyd and acrylic systems, water-based emulsion paints, primers, fillers and colour concentrates, and it can be combined with a high-speed disperser for pre-mixing and a let-down tank for circulation grinding. Because ambient temperatures in the region stay high all year, the cooling circuit is sized with margin and can be tied into an existing chilled water loop or a small plate heat exchanger. Plants that run several colours per week usually keep two 60L chambers and swap product by flushing with solvent and a short media clean-out, which keeps changeover under one hour.

Every WMS60 agitator bead mill leaves the factory after a 72-hour loaded running test that records vibration, seal leakage, bearing temperature and outlet fineness; those records travel with the machine as part of the delivery documentation. Shafts and discs are dynamically balanced, chambers are hydrostatically tested, and electrical panels are wired to IEC conventions with a wiring diagram, operation manual and spare-part list supplied in English. The machine is built under an ISO 9001:2015 quality management system, and CE-compliant electricals with guarded drives are available for buyers who need them. The warranty covers 12 months on the complete machine excluding grinding media and normal wear parts, spare parts remain available for at least ten years after delivery, and remote commissioning support over video is included so that a new line can be started without waiting for an engineer to fly in.
