Large Capacity Agitator Bead Mill WMS300 300L 110kW For North America Automotive Coatings

The WMS300 agitator bead mill is the high-throughput workhorse of the WMS range, pairing a 300-litre horizontal grinding chamber with a 110kW main motor to deliver 300 to 2600 kg/h of dispersed coating or pigment paste. It is aimed at automotive OEM and refinish coating plants, industrial coating producers and pigment paste suppliers across the United States, Canada and Mexico, where a single agitator bead mill is often expected to feed several let-down tanks around the clock. The bearing housing is sized for continuous duty, and the seal is built as a cartridge so that a worn seal can be replaced from the front of the machine without pulling the chamber out of the frame. A variable frequency drive provides soft start and lets the process engineer trim agitator tip speed to match each formulation, which keeps specific energy consumption predictable and prevents over-grinding of heat-sensitive resins. Chamber and shaft are SS304, discs are hardened alloy steel, and the cooling jacket accepts a closed-loop water circuit.

• Agitator Bead Mill At Production Scale: a 300L chamber with a 110kW agitator drive moves up to 2600 kg/h, letting one mill replace several smaller units on a crowded production floor
• Cartridge Seal Changeover: the seal cartridge is removed from the front without dismantling the chamber, cutting a planned seal service from a full day to a few hours
• Continuous Duty Bearing Housing: oversized bearings and a rigid frame keep vibration low through three-shift operation, protecting agitator disc concentricity and fineness repeatability
• Predictable Specific Energy: VFD control of agitator tip speed lets engineers fix energy input per kilogram, the key variable for reproducing automotive colour matches
• Closed-Loop Cooling Ready: the jacket and piping are prepared for connection to a plant chiller loop, so product temperature is controlled by the facility instead of by municipal water
• Wear-Managed Grinding Zone: hardened discs, replaceable chamber liner sections and a quick-clean screen keep the grinding zone in tolerance across years of abrasive pigment work

North American customers typically deploy the WMS300 agitator bead mill in automotive OEM and refinish coating plants, industrial maintenance coating production, pigment paste manufacturing and high-volume ink operations. It suits circulation grinding of solvent-borne and water-borne systems, and it can be configured for a pre-mix plus mill plus let-down arrangement or for a multi-pass loop through an in-line filter. Where a plant runs several colours, two 300L mills are often installed in parallel so that one can be cleaned while the other keeps feeding the filling line. The frame accepts forklift access on all four sides, the discharge height is set for standard tote and tank connections, and electricals can be prepared for 460V / 60Hz supply with UL-listed components on request.

Every WMS300 agitator bead mill is assembled in an ISO 9001:2015 certified facility and run under load for 72 hours on a reference paste, with vibration signature, bearing temperature, seal leakage and fineness results recorded in a shipment test report. Chambers are hydro-tested at 1.5 times working pressure, shafts are dynamically balanced, and disc assemblies are checked for run-out before installation. The delivery set includes electrical schematics, a cooling circuit P&ID, an English operation and maintenance manual, a spare-part list and material certificates for wetted parts; 460V / 60Hz builds can be supplied with UL-listed electrical components. The machine carries a 12-month warranty excluding grinding media and wear parts, wear parts remain available for ten years, and startup support is offered either remotely or on site with a commissioning checklist that covers alignment, flushing, media charging and first-batch validation.
