The SWR FlowJam detects various kinds of bulk solids flow and distinguishes between material flow and material jam or standstill. The FlowJam is a non-contact blocked chute detector utilising microwave technology. Material movement is detected by means of the Doppler principle, offering a reliable solution for flow/no flow detection in various processes.
The benefit of FlowJam’s non-contact sensor is that it eliminates contamination. Highly effective and reliable, the FlowJam’s use of its microwaves guarantees a penetration of any material build-up on the sensor, and therefore can detect the material flow behind it. Likewise it is possible to detect through non-metallic box walls, casings or conduits. Even in difficult conditions like high process temperatures, pressure or dust EX-zones, the FlowJam can be used by means of a process adapter. For applications requiring high sensitivity eg, detecting a small amount of dust, the FlowJam-H is available. FlowJam is also available in an S-version for installation in places where space is constrained.
Practical applications include:
* Monitoring of plastic injection in steel plants
Plastic as fuel is injected via several lances in the blast furnace. It is very important for a constant quality of the burning process that the fuel distribution around the blast furnace is guaranteed. It is for this reason that every lance is monitored by FlowJam, so that every jam can be detected instantly, by which the process can be stopped automatically and the concerned lances cleared by the injecting of nitrogen.
* Monitoring of raw meal cyclones in cement plants
The FlowJam monitors the cyclone through special ceramic fittings, used for high temperature isolation, in order to prevent jams inside the cyclone. Temperature inside the cyclone: 600°C. Mass flow rate: ca. 50 t/h.
* Monitoring of screw-conveyors in gypsum plants
The FlowJam is installed in the discharge part of the screw to monitor the continuity of the material flow. As soon as the material flow gets interrupted, the FlowJam signals it by switching the relays, so that the operator can react appropriately.
