PHM Series Hydraulic Triple Roller Mill & Three-Roll Grinder (PHM150 – PHM400)
PHM Triple-roller mill is mainly used in paint, printing ink, pigment, plastic, etc., especially mill and disperse products with high viscosity and small granularity. Due to mutual squeezing of three horizontal alloy bowls and friction with different velocity, great milling effect can be realized. The Triple-roller mill adopts sprocket driven, the gear is immerged into lubricant, so service life of the machine is maximum prolonged, noise and energy consumption is reduced. The Triple-roller mill’s bowl adopts wear-resistant alloy steel, has a longer life.
PTM Series Hydraulic Triple Roller Mill & Three-Roll Grinder
The POLYC PTM Series Hydraulic Triple Roller Mill is an extreme-duty grinding and dispersing machine engineered specifically for ultra-high-viscosity pastes up to 3,000,000 cps. Utilizing intense hydraulic nip-shear forces generated between three horizontally aligned, differential-speed rollers, it effortlessly crushes pigment agglomerates in offset inks, electronic silver pastes, pharmaceutical ointments, and advanced sealants where traditional liquid bead mills fail.
POLYC PTM Series Hydraulic Triple Roller Mill: Automated Hydraulic Gap Control with heavy-duty cast frames, designed for continuous, perfectly uniform sub-micron dispersion.
Engineering Architecture & Core Advantages
Precision Hydraulic Tensioning
Unlike manual handwheels which rely on operator feel, the hydraulic system delivers a perfectly stable and quantifiable clamping pressure. This ensures precise micron-level gap adjustments between the rollers, resulting in highly repeatable batch fineness.
Dynamic Thermal Camber Control
Intense friction causes metal rollers to expand unevenly (thermal bowing), destroying the uniform nip gap. POLYC rollers feature continuous internal chilled water passages. This extracts heat instantly, keeping thermal rise below 10°C for UV inks and pharma gels.
Zero-Metal Contamination (Ceramics)
For pure white cosmetics, battery pastes, and electronic silver slurries, metal ion shed is catastrophic. We offer barrels crafted entirely from high-purity Zirconia (ZrO2) or Alumina (Al2O3) ceramics, guaranteeing absolutely zero metallic contamination during operation.
Operator Safety & Emergency Braking
A three roll mill exerts extreme mechanical nip pressure. POLYC mills are heavily fitted with prominent emergency brake buttons, safety nip guards, and optional trip sensors that instantly release hydraulic tension to prevent operator injury.
