High Flow Agitator Bead Mill WMS400 400L 132kW For South America Agrochemical Slurry

The WMS400 agitator bead mill is the largest chamber in the WMS series, combining a 400-litre grinding volume with a 132kW main motor for high-flow circulation grinding in the 400 to 3500 kg/h range. It was specified with agrochemical formulators and pigment paste producers in Brazil, Argentina, Chile, Colombia and Peru in mind, where suspension concentrate and oil dispersion formulations demand a narrow particle size distribution, a high recirculation rate and very stable product temperature across long campaigns. The agitator shaft accelerates a large bead charge while the screen and discharge area use a wide open flow path, keeping circulation rates high without building back pressure; the four-point cooling jacket is rated for warm inlet water and humid plant conditions. Hardened alloy discs and replaceable wear sections protect the grinding zone when abrasive technical material and crystalline active ingredients pass through, and the double-end seal includes a flush port so that water-based and solvent-based campaigns can be separated by a documented cleaning cycle.

• Agitator Bead Mill High-Flow Path: an enlarged screen open area and short discharge route support high recirculation rates, which is what agrochemical SC milling needs for a tight D90
• 132kW Grinding Power: the largest agitator drive in the range sustains production-scale campaigns without falling back on longer milling times that widen the particle size curve
• Tropical Climate Cooling: the cooling jacket is sized for inlet water above 30 degrees Celsius and high humidity, holding viscosity and preventing thermal degradation of sensitive actives
• Wear-Protected Grinding Zone: hardened alloy discs and replaceable liner sections absorb the abrasion of crystalline technical material and mineral pigments
• Campaign Changeover Control: the seal flush port and drain arrangement allow a documented wash sequence between water-based and solvent-based products, limiting cross contamination
• Mechanical Reliability At Scale: a rigid frame, oversized bearings and dynamically balanced agitator shaft keep vibration low so the mill can run continuously through a full campaign season

The WMS400 agitator bead mill is normally installed as the central mill in agrochemical formulation plants producing suspension concentrate, oil dispersion and suspoemulsion, and in pigment paste or industrial coating plants that need very high output from a single machine. It works well in a multi-pass loop with a large holding tank, where the circulation rate determines how fast the batch reaches target fineness, and it can be combined with a high-shear pre-mixer and an in-line filter before filling. Because South American formulators often run several active ingredients through the same agitator bead mill in one season, the discharge arrangement and cleaning procedure are designed around campaign changeover, and cooling can be tied to a chiller loop or an evaporative system depending on site water quality and ambient conditions.

Each WMS400 agitator bead mill is built in an ISO 9001:2015 certified workshop and tested for 72 hours on a reference slurry, with vibration, bearing temperature, seal leakage, flow rate and fineness recorded in a report that ships with the machine. Chambers are hydro-tested, shafts and agitator disc stacks are dynamically balanced, and seal cartridges are bench-tested for barrier-fluid retention before assembly. Delivery documentation includes electrical schematics, a cooling and flush piping diagram, an English operation and maintenance manual, a recommended spare-part list and material certificates for wetted parts, with CE-compliant electricals available on request. The complete machine carries a 12-month warranty excluding media and wear parts, wear parts are stocked for ten years, and remote commissioning covers alignment checks, media charging, first-batch fineness validation and operator training so that a new line reaches rated output quickly.
