Mixers
The PSK Multi-Function Dispersing Kettle (Platform Triple Shaft Mixer) by POLYC integrates low-speed strong stirring, high-speed dispersion, and high-shear emulsification into a single vessel. Designed for medium to ultra-high viscosity materials including acrylic plasters, silicone plasters, wall putty, pastes, gels, and slurries, the PSK handles capacities from 1 m3 to 15 m3 with three independently controlled shafts eliminating the need for multiple separate machines. High-wear PTFE scrapers ensure complete discharge with zero batch residue, while optional vacuum defoaming and jacketed heating/cooling provide precise process control.

Description
The PSK Multi-Function Dispersing Kettle (Platform Triple Shaft Mixer) by POLYC professional chemical equipment manufacturer integrates low-speed strong stirring, high-speed dispersion, and high-shear emulsification into a single vessel. Designed for medium to ultra-high viscosity materials including acrylic plasters, silicone plasters, wall putty, pastes, gels, and slurries, the PSK handles capacities from 1 m3 to 15 m3 with three independently controlled shafts eliminating the need for multiple separate machines.
Three-in-One Processing: Combines low-speed strong stirring, high-speed dispersion, and high-shear emulsification. Each shaft can be activated independently or simultaneously based on your material requirements, replacing three separate machines with one versatile system.
PTFE Scraper System: Adopts high-wear PTFE scrapers that continuously remove sticky or high-viscosity formulations from the vessel internal surfaces. Secures complete discharge metrics with zero batch residue, critical for high-value formulations and color change operations.
High-Viscosity Capability: Specifically designed for medium to high viscosity and thixotropic materials including paste, gel, and slurry with poor fluidity that standard mixers cannot handle effectively. The triple-shaft configuration ensures uniform mixing even at the highest viscosities.
Versatile Agitator Configurations: Choose from frame, anchor, butterfly, ribbon, high-speed dispersing disc, or emulsifying head configurations matched to your specific material characteristics and process requirements.
Vacuum & Temperature Control: Optional vacuum defoaming system eliminates bubbles for bubble-free products; configurable jacket for heating or cooling enables precise temperature control throughout the process.

Typical reference values only. Actual results depend on formulation, bead material, and process conditions. Material testing is recommended before final selection.
Equipment Selection
Select model based on required batch capacity: PSK-1 (1m3) through PSK-15 (15m3), with stirring power from 4kW to 22kW and dispersing power from 11kW to 75kW.
Evaluate material viscosity and thixotropy: the triple-shaft configuration is specifically designed for medium to ultra-high viscosity materials that standard dual-shaft mixers cannot handle effectively.
Determine whether vacuum defoaming is required for bubble-free products, and whether jacketed heating/cooling is needed for temperature-sensitive formulations.
Select appropriate agitator configurations (frame, anchor, butterfly, ribbon, dispersing disc, emulsifying head) based on material characteristics and process requirements.
Consider discharge method: PTFE scraper system ensures complete discharge, but hydraulic discharge or other methods may be preferred for certain applications.
Process Engineering
The low-speed stirring shaft drives a frame or anchor agitator that slowly sweeps the vessel walls, moving material toward the high-speed dispersing zone.
The high-speed dispersion shaft drives a toothed disc that creates intense shear and turbulence, breaking down agglomerates and dispersing pigments and fillers.
The high-shear emulsification shaft (when equipped) generates extreme shear through a rotor-stator configuration, emulsifying immiscible phases and reducing particle size.
PTFE scrapers attached to the low-speed agitator continuously wipe material from vessel walls, preventing buildup and ensuring complete discharge with zero residue.
All three shafts operate independently, allowing operators to activate only the shafts needed for each processing stage, optimizing energy consumption and processing time.
Equipment Benefits
Three-in-one processing replaces three separate machines (stirrer, disperser, emulsifier) with one versatile system, reducing capital investment and floor space.
PTFE scraper system ensures complete discharge with zero batch residue, critical for high-value formulations and minimizing material loss during color changes.
Specifically designed for medium to ultra-high viscosity and thixotropic materials that standard mixers cannot handle effectively.
Three independently controlled shafts provide flexible processing strategies, optimizing energy consumption and processing time for each stage.
Optional vacuum defoaming and jacketed heating/cooling enable precise process control for bubble-free products and temperature-sensitive formulations.
Direct manufacturing in POLYC 9,000 m2 facility ensures quality control, competitive pricing, and rapid delivery for export.
