MARS Tramp Metal Removal System
The MARS™ Tramp Metal Removal System is designed to remove tramp metal without having to stop production or put staff in harm’s way. It removes the need to climb onto conveyor belts and to physically handle material.
With no limitations of belt size, speed or construction the MARS™ will increase production uptime and reduce costly maintenance caused by damage to plant further on in the process. The MARS™ can be operated by any metal detector with a trip facility.
Unlike magnets, using MARS guarantees 100% removal of the tramp metal. Magnets may miss deeply buried or weakly magnetic tramp metal.
The primary assemblies of the MARS™ include the upper structure and the flattening/slider bed.
The MARS™ upper structure includes the control box, the air tank, the air cylinder, the splash shields and other components. It also includes the plow blade and its supporting structure. This assembly spans the conveyor above the belt, with the plow blade facing the tail pulley end of the conveyor.
The plow blade will discharge material either to the left or to the right of the conveyor (looking from the tail pulley toward the head pulley). The right-hand or left-hand configuration of the plow blade is specified when the MARS™ is ordered and is permanently set at the factory.
The MARS™ flattening/slider bed is a rectangular assembly that replaces the idlers underneath the plow blade and continuously supports the belt. The plow blade flattens the belt against this bed to divert tramp metal off the conveyor. The bed is specially equipped with UHMW to protect the belt and to ensure proper flow of material.
In general, the MARS™ is a few inches wider than the belt and is approximately twelve feet long. Its exact dimensions depend on the width of the conveyor.
The Counter-Balance Option. The MARS™ uses compressed air (either from the plant’s air supply or from a separate compressor) to control its plow blade. Without proper air supply, the blade will remain in the down position, continuously diverting material off the belt. Therefore, if there are concerns about the consistency of the air supply to the MARS™, a counter-balance option is offered which will prevent the blade from lowering onto the belt during a loss of air pressure.
