PiT Indicator Mill
Suitable for vertical mills (ball and roller) and horizontal ball mills Indication of mill filling degree.
Benefits:
- Exact analysis of mill filling degree even in multi mill set-ups at the same place
- Scalable: Easy and inexpensive to scale to multiple mills
Features:
- Calibrate measured filling degree in the control room against „expected filling degree“ including graphical user interface with trending and alarming
- Two microphones per mill to allow for advanced signal processing and to eliminate influences by disturbing sounds (i. e. other mills)
- Calculation of filling degree by using advanced signal processing with pattern recognition on acoustic measurements
- Automatic feature selection and extraction (significance ranking) of existing process data
- Option: Process interface to e. g. OPC server, Modbus RTU Master, Modbus TCP Client, ProfibusDP Master, Analogue etc.
- Modularity: Possibility to upgrade to PiT Navigator Ball Mill
CONTROL:
PiT Navigator Mill
Advanced Auto-Optimiser for permanent optimisation of mill and separator. Suitable for vertical mills (ball and roller) and horizontal ball mills
Benefits:
- Reduced grinding degree deviation (Blaine) by up to 30%
- 2% and 6% less specific energy consumption
- 8 to 15 % increased throughput
- Full automatic closed-loop control
- Clinker type and recipe independent optimisation
- Elimination of lab delay through Blaine prediction by a sophisticated soft sensor
- Optimised mill start up
- Fast adaptation to process changes and changes in clinker types
Features:
- Online vibration monitoring of separator allows for Blaine prediction and quality based throughput maximisation
- Recipe independent closed-loop control by using filling degree, Blaine prediction and Advanced Process Control
- Self learning of controller parameters for different recipes
- No re-parametrisation at new recipes
- Fast and stable control for less specific energy consumption
- Intensive usage of existing process data
- Automatic feature selection and extraction (relevance ranking)
- Remote support included Integration of existing mill monitoring systems
