Basket Mill for Emulsion Paint
PZM Series Hydraulic Immersion Basket Mill for Emulsion Paint
Product Overview & Operating Principle
The PZM series Hydraulic Immersion Basket Mill is an all-in-one wet grinding and dispersion machine designed specifically for architectural emulsion paint, water-based coatings, and high-mix colorant production. Combining high-speed pre-dispersion and intensive bead milling inside a single vessel, it eliminates the need for external slurry feed pumps, connecting hoses, valves, and piping manifolds — reducing material loss to near-zero and slashing batch changeover downtime.
Self-Recirculating High-Shear Immersion Dynamics
During operation, the upper suction impeller generates a powerful vortex that continuously draws raw paint slurry into the double-walled grinding basket. Inside the basket, high-speed milling pins energize micro ceramic grinding beads to deliver intensive impact and shear. The refined slurry exits through the bottom dynamic screen, where a lower Cowles dispersing disc propels the material outward to maintain full tank circulation. This continuous cycle delivers narrow sub-micron particle size distributions across formulations with viscosities up to 8,000 cps.

Key Engineering Highlights
All-in-One Process Integration
Pre-dispersion, fine wet milling, and final blending are completed in a single container, eliminating transfer hold-up and contamination risks for water-based paint systems.
5-Minute Fast Color Changeover
The electro-hydraulic lift column elevates the grinding basket clear of the batch tank, allowing operators to lower the basket into an auxiliary solvent container for rapid, residue-free washdowns between tint colors.
Low Grinding Media Charge
Compact basket volume requires minimal zirconia bead loading while achieving superior grinding kinetics and high energy efficiency for high-volume paint batches.
Double-Walled Cooling Jacket
Cooling water circulates through both the grinding basket jacket and the mobile vessel wall, maintaining precise temperature control for thermal-sensitive water-based polymer emulsions.
Precision Engineered Details
Wear-Resistant Ceramic Pins
High-purity zirconia pins ensure zero metallic contamination for pure white emulsion paints.
Double-Walled Grinding Basket
Jacketed milling chamber for rapid heat dissipation during continuous paint dispersion.
