Basket Mill for Pigment
PZM Series Hydraulic Immersion Basket Mill with Ceramic Grinding Pins (Integrated Batch Wet Bead Milling & Dispersing System)
Product Overview & Operating Principle
The PZM series Hydraulic Immersion Basket Mill is an advanced all-in-one wet grinding and dispersion machine purpose-built for multi-color batch production, pilot plant trials, and industrial chemical manufacturing. By performing pre-dispersion and sub-micron bead milling within a single vessel, it eliminates the need for auxiliary feed pumps, external hoses, valves, and mechanical transfer manifolds — preventing product hold-up and cutting batch changeover downtime by over 60%.
Self-Recirculating High-Shear Immersion Dynamics
During operation, the top suction impeller pulls liquid and agglomerated powders downward into the double-walled grinding basket. Inside the chamber, high-wear-resistant ceramic grinding pins energize micro zirconia beads ($\Phi$ 1.0 – 2.5 mm), generating intense collision and hydraulic shear. The dispersed slurry exits through the bottom dynamic separation screen, where a lower Cowles dispersing disc propels the material outward to maintain full-tank axial circulation. This continuous turnover cycle efficiently processes formulations with viscosities up to 8,000 cps.
Key Technical Highlights
- High Wear-Resistant Ceramic Grinding Pins: Fitted with high-purity zirconia/alumina ceramic grinding pins that withstand severe abrasive friction, completely eliminating metallic contamination and color graying in electronic pastes, white coatings, and pharmaceutical suspensions.
- All-in-One Process Integration: Pre-dispersion, fine wet grinding, and final blending take place in a single container, eliminating product waste in external piping circuits.
- 5-Minute Fast Color Changeovers: The electro-hydraulic lift column raises the basket out of the batch tank within seconds, allowing rapid immersion in an auxiliary solvent bucket for thorough, residue-free cleaning.
- Double-Walled Cooling Basket & Tank: Dual cooling jackets around both the milling basket and the mobile vessel dissipate mechanical heat efficiently, maintaining batch temperatures within safe limits for thermal-sensitive formulations.
- Protected Electrical Junction & Ex-Proof Console: Features an integrated terminal junction box for clean, vibration-free cable routing and an aluminum alloy explosion-proof operator console compliant with international safety directives.
