Challenge: Material blockage can occur at chute and other transfer points resulting in loss of material due to overflow, damage to the conveyors, plant downtime, wastage of materials, expenses and delays.

To prevent and detect blockages, it is essential that every chute/hopper installs instruments for detecting blockages. The instrument measures material build-up and provides warning. The feeding process can then be stopped to prevent the build-up.

Solution: Toshbro Controls offers many solutions for reliably and accurately detecting a jam in the chute/hopper, thereby eliminating plant downtime, minimizing losses and improving productivity.

A. RF Capacitance Level Switch

The Nivolarm series of RF Capacitance Level works on the field proven RF Technology. It is available in several configurations, for sensing presence of material or level.

Benefits

# Can be mounted from top as well as from sides
# Probes with ceramic insulation for high temperature, and
# Suitable for detecting powder, granular or lumpy solids.

B. FlowJam

The FlowJam detects material movement of Bulk solid flows. The system works contactless using microwaves. The material movement is detected by means of the Doppler’s principle. When the material flow is interrupted the FlowJam signals it by switching the relays.

Benefits

# Can be installed on the hopper/chute and also at the discharge point, and
# Being non-contact, the instrument is not subject to wear and tear.
