Transportation of minerals
In the extraction or processing of natural stones those stones (basalt and lava) in different sizes are transported to a first screening by a conveyor belt. In some cases the screen may occasionally become blocked. As soon as the screen is clogged, the stones jam in the feed chute. If this blockage reaches the previous belt, it might be damaged. The frequent consequences: costly and time-consuming production downtimes.
|Material:||Stones (basalt and lava)|
|Installation place:||Feeding chute behind conveyor belt|
|Function:||Protection of conveyor belt|
The ProGap S with filling-signal-suppresion is a universal and flexible sensor for level detection, based on proven microwave technology. In this application the ProGap S is used to detect the dumming of the stones in the discharge chute after the conveyor belt. Upon reaching a critical level monitored by the ProGap S, the transportation is (initially) stopped. Because of the continuous working screen below, normally the blockage will be dissolved automatically. If the screen is unable to remove the blockage over a period of time, an alarm is issued to the factory staff and the clogged screen can be manually cleaned.
- Protection of screen and conveyor belt against damage
- Reduction of downtime, less production downtime due to blockages
