Rod Pin Sand Mill HSS30 30L 37kW Horizontal Grinding For Indian Agrochemical Paste

The HSS80 horizontal sand mill is an 80-litre closed grinding unit built around a rod pin rotor, a configuration that concentrates energy in a small volume and is therefore well suited to agrochemical suspension concentrate where a tight D90 decides both suspension stability and biological efficacy. The 45kW drive runs 0.8 to 1.5 mm zirconia or glass media, and the pin geometry keeps the media charge moving even at higher solids loading, so formulators can reach three to five micron D90 in fewer passes. Output ranges from 120 to 1000 kg/h, which matches the batch sizes of mid-size formulation plants in India, Bangladesh and Sri Lanka. Electricals accept 380 to 415V with a tolerance band wide enough for common site fluctuation, the cabinet is dust-filtered for humid formulation halls, and the rotor and chamber wear surfaces can be hardened or coated for abrasive technical material. The integrated double mechanical seal with barrier fluid keeps active ingredient out of the bearing housing and keeps leakage away from the product stream. In the workshop it runs as a horizontal agitator bead mill, and every sand mill duty from pre-dispersion to fine grinding passes through the same closed chamber.

• Rod Pin Rotor Geometry: pins on the rotor and chamber wall create a high energy density zone, so suspension concentrate reaches target D90 in fewer passes than a plain disc rotor
• Built for Abrasive Actives: hardened or coated pins, replaceable wear sleeves and a thick chamber wall handle crystalline technical material without rapid grooving
• Voltage Tolerance: drive and controls accept 380-415V with a wide tolerance band, which suits plants running on mixed grid and captive power
• Dust and Humidity Protection: IP55 motor and filtered cabinet ventilation protect the drive train in humid formulation halls with heavy powder charging
• High-Flow Separation: a large open-area screen supports high circulation rates so the loop reaches fineness quickly without excessive back pressure
• Simple Media Changeover: the chamber drain and quick-release screen let operators swap media size between campaigns in under an hour, with no special tools

The HSS80 horizontal agitator bead mill is used mainly for agrochemical suspension concentrate and suspoemulsion, and also for pigment paste, textile dye dispersion and leather finishing compounds across India, Bangladesh, Sri Lanka and Nepal. In a typical installation the mill works in a circulation loop with a 2 to 5 m³ holding tank and a high-shear pre-mixer, and the batch is milled until the laser diffraction D90 falls inside the specification window. Because plants in the region often run ten or more active ingredients in a season, the quick-release screen and drain arrangement matter as much as grinding performance: a documented clean-out between campaigns prevents cross contamination that would otherwise fail a customer's residue check.

Each HSS80 horizontal sand mill is assembled in an ISO 9001:2015 certified plant and run for 72 hours on a reference suspension concentrate before dispatch; test data covers vibration, bearing temperature, seal leakage, flow rate and fineness. Chambers are pressure tested at 1.5 times working pressure, rotors are balanced, and pin wear surfaces are dimensionally checked against a drawing-based checklist. The shipment includes an electrical schematic, cooling and flush piping diagram, English operation and maintenance manual, spare-part list and material certificates. The machine carries a 12-month warranty excluding media and wear parts, wear parts are stocked for ten years, and remote commissioning supports alignment checks, media charging, first-batch validation and operator training, with an optional on-site visit for plants starting a new formulation line.
