Crusher/Grinder/Shredder Motor Interlocks
The performance of size reduction equipment like crushers or grinders can be optimized by controlling the in-feed in order to:
- Help prevent jamming
- Improve the uniformity of the resultant product
- Enhance overall production efficiency
By installing an NK Technologies’ Current Transducer or Power Transducer to monitor the in-feed to a crushing process, the speed of the in feed drive can be slowed when the crushing motor is working too hard, or the speed can be increased when the crusher is under worked. The analog 4-20mA proportional signal is fed directly into a VFD, and the drive does the rest of the control.
Additionally, NK Technologies’ Current Operated Switches installed on other conveying motors can be used to signal malfunction (for example over-load or motor failure) to help prevent costly equipment damage.
NK technologies current sensors come in a variety of configurations for quick and simple installation either for the OEM or End-User.
