Rotary barrel smoothly shot blasts small
parts
A novel 'Multi-Tumbler' system to shot blast bulk work pieces ensures that the blast stream reaches all surface areas, thus producing even and consistent blast results.
Specially designed rotary barrel - the central feature of the MT machine series is the geometry of the rotating barrel The inside wall of the barrel features specially contoured ridges, while the bottom is shaped in the form of a three-sided pyramid

Vibratory bowls process various part sizes
For a vehicle components manufacturer, a customised rotary bowl finisher was devised to process various part sizes and shapes in a 'continuous batch' operation.
Overhead rail shotblast system is Europe's largest
Europe's largest overhead rail shot blast system has been installed at a German iron foundry to to clean and remove residual casting sand from wind power system components.
This unique design creates the innovative 'multitumbling' action of the different barrel elements: when the drum rotates, the ridges on the internal wall of the barrel tumble and mix the workpieces.
At the same time the pyramid causes the parts at the bottom of the barrel to move to the top of the mass.
This multi-tumbling action ensures that the blast stream reaches all surface areas, thus producing even and consistent blast results.

A highly efficient shot blasting system for deburring and surface finishing the casings and internal surfaces of transmission housings has a cycle time of 26s/component.
Shot blasting suits heavy and delicate work
Tumble belt batch system, targeted for foundries and forge shops, and a compact drag finishing system, designed for special vibratory finishing were shown at EMO.
Brightly cleaned parts surface, free of sand, rust or scale, are achieved in short cycle times with an MT system with a highly consistent finish.
* Gap-free working unit - compared to conventional tumble belt batch shot blast systems the barrels of MT systems don not have pinch points where small work pieces get caught and damaged.
They tumble freely within the rotating barrel.
This prevents damage to the parts as well as to the machine.
* High uptimes and low maintenance costs - downtimes are significantly reduced by the smoothly process of small work pieces and the highly wear resistant rotating barrel made of manganese steel.
The replacement of a worn barrel is easy to manage because the system is developed as one single barrel.
* MT machines can easily be integrated into automated processes - they can be configured as stand alone units or as part of a fully automatic system including loading of raw parts and unloading of finished parts!.
Available automation options include: lift and tip loaders, vibratory hoppers, unload conveyor belts, automatic media top-up, shot flow monitors and many others.
* Capacities ranging from 60 to 950 litres - the MT product line consists of six high-performance types with barrel capacities ranging from 100 up to 950 litres.
Capacity by weight varies from 200kg to 3100kg per batch.
* The right blast wheel for your application - the smaller models are equipped with 11kW blast wheels; and the larger models, after the choice of blast wheels with a driving power up to 56kW.
This ensures that even the most demanding cleaning and shot blast process can be handled effectively.
