Belt Conveyor Contaminant Removal Systems

Non-Metallic's

When relatively large pieces of non-metallic foreign material within a belt conveyor process stream disrupt downstream process, the modified Multotec hammer removal system provides a unique solution.

Benefits

• The primary hammer (swing-arm) unit has adjustable "fingers" for selective removal of belt material.
• Electronic sensors utilising contaminant physical properties initiate the sweeping cycle.
• The controlled amount of displace material (with contaminant) now screened to allow separation of two components.
• Screen undersize and oversize routed back to process or to a road transport container for final handling.

Metallic (Ferrous and non-ferrous)

The Multotec TrampmasterTM, is a modular system for automatically sensing and removing tramp metal from moving conveyor belts. The system consists of a Multotec hammer sampler (adapted to remove tramp metal) and ancillary equipment for separating the tramp metal and recycling product removed from the conveyor.

Benefits

• Protects expensive equipment e.g. ceramic lined chutes and cyclones, crushers, etc. from damage caused by tramp iron. Downtime and operational costs associated with equipment failure now significantly reduced.
• Penalties are often imposed by customers where tramp is detected in a product supplied e.g. coal. The TrampmasterTM can substantially reduce this cost.
• In many conventional tramp systems, the conveyor is tripped when tramp is detected. Removal tramp is done manually. Stopping a conveyor has no production and therefore cost implications. Manual removal or tramp can also be unreliable and unsafe. The TrampmasterTM addresses both these issues.

Advantages over conventional systems

• Removes both magnetic and non-magnetic metal from moving conveyor belts.
• Mechanically removes and clean cut of material systems often fail to remove tramp metal from under the conveyor burden.
• Readily retro fitted to an existing conveyor installation.

Operating Philosophy

An electrical control system manages the detection of tramp metal, the removal action, the discharge of the tramp metal to a waste skip and the operation of ancillary equipment. An eddy current detector senses the tramp metal on the main product conveyor. The detector signal to the control system provides information on the tramp position, size and type. A hammer traversing the belt across the material flow removes a cut product including the tramp metal. This cut is fed onto a recycle conveyor belt by a vibrating feeder.

A secondary eddy current detector senses the position of the tramp metal on the recycle belt. A flapper gate is activated to discharge the tramp metal to a waste skip. Product in the recycle stream is returned to the main product conveyor. A backup eddy current detector checks that all product passing the hammer position is tramp free.

Key components of the systems are the electronic control systems, the eddy current detector preceding the hammer tramp remover and the hammer tramp remover itself. Many applications will not require a detector for final checking and a chute feeds all removed material to a road container. (e.g. 6t capacity).
