granumill® size reduction systems

Product catalog summary
Overview: The GRANUMILL® size reduction systems are designed for milling, grinding, and comminuting both wet and dry materials. These systems combine low-speed screening and high-speed impacting to meet diverse processing challenges efficiently.
Benefits:
  • Dust-free and easy to clean.
  • Direct Variable Speed Drive eliminates the need for belts.
  • Intuitive controls for superior operation.
  • Facilitates easier validation and scale-up.
  • Reduced maintenance and cost-effective.
  • Custom configurations available.
Particle Size Reduction: GRANUMILL® systems can reduce particle sizes from 10 to 400 mesh (2000 - 27 microns). The system includes an inlet, chamber with rotor, screen, and discharge, with tightly controlled rotor speed and feed rate for a narrow particle size distribution.
Impact and Screening Mills:
  • Impact Mills: Utilize a high-speed rotor to shatter and reduce product size, with a screen to ensure appropriate sizing.
  • Screening Mills: Use a low-speed rotor to push product through a screen, ideal for friable materials.
Maintenance and Cleaning: Features quick-release housing for easy disassembly and cleaning, with all stainless steel construction and NEMA 4X control panel.
Scale-up and Validation: Consistent rotor blade types and tip speeds between R&D and production systems simplify scale-up and validation processes.
Cost-Effectiveness: The system supports both high-speed impact milling and low-RPM screening, adhering to SUPAC guidelines.
Quiet Operation: Innovative rotor design and housing geometry ensure quiet operation with a narrow particle distribution curve.
Efficiency: Variable speed operation allows for both high-speed fine grinding and low-speed deagglomeration. Touch screen controls and machine integration meet compliance requirements.
Design Advantages:
  • GMP design with interchangeable rotor designs for particle size control.
  • Adjustable feed and discharge heights.
  • Tool-free assembly/disassembly and quick clamps for speedy product change-over.
Specifications: The document provides detailed specifications for different models, including speed, throughput, dimensions, and finished particle size.
Design Options: Options include explosion-proof construction, water jacketed housing, vacuum feeding, efficient nitrogen inerting, and wash-in-place configurations.
