Munkebo Tower System

The increasing disposal costs for expendable blasting media favour the use of reusable blasting media. With our innovative tower system you bring your complete recovery and recycling system to the site.

The tower system consists of one suction unit, one abrasive cleaning unit and two vacuum/storage silos. All modules have been well proven for the on site and in house contractor.

The modules are arranged with the vacuum silo on the top, followed by the abrasive cleaning unit, the storage hopper and the blast machine on the bottom.

The suction unit is normally located near to the tower. The suction unit provides vacuum to the upper silo and abrasive media can be retrieved as in a standard vacuum system.

When the abrasive media reach its upper level in the vacuum silo, the vacuum is automatically released from the silo. This is done by directing the airflow through the abrasive cleaning unit, instead of the vacuum silo. Silo discharge through the abrasive cleaning unit is done semi-automatically.

The airflow from the suction unit is used for the air-wash system in the abrasive cleaning unit.

When the abrasive media has been discharged from the vacuum silo, through the abrasive cleaning unit into the storage hopper, the system is ready for retrieval of abrasive media again.

Munkebo Grit Recovery Unit

The Munkebo Grit Recovery Unit is designed for the retrieval and transport of abrasive media.

The Munkebo Vacuum Recovery Unit is electrically powered and designed to substantially reduce abrasive retrieval and site cleaning costs. The units are driven by a high powered electric induction motor coupled to a heavy duty vacuum pump. The cyclone filter section is fitted with safety relief valve and automatically sequenced reverse jet filter system.

The powerful Munkebo units can be used where other equipment cannot reach, as they can transport abrasive up to 75 metres (using the MB3000).

Only clean air is vented to atmosphere and the separated dust is accumulated in the waste bin for easy disposal. Various sizes of Munkebo systems are available to suit site conditions, abrasive types and different recovery rates.

Our hire fleet includes the MB2000 and MB3000 units.

The Munkebo can be used in conjunction with a Portable Site Dust Collector, and Storage Silo.

As these are large recovery machines, please refer to the power requirements as shown on the following page.

The Munkebo is available for sale or hire from the The Surface Finishing Equipment Group - Hogg Blasting and Finishing Equipment in the Northeast UK and Abraclean in the Northwest UK.
