AGTOS Rubber belt tumble blast machine

The AGTOS Product Range

Our standard program of rubber mill tumble blast machines (MG) is filling volumes ranging from 50 to 550 liters.

The choice of machine depends on the volume and the batch weight of the work pieces to be blasted. In addition, other parameters such as a work piece’s geometry, material and temperature should be considered when selecting a rubber mill tumble blast machine.

In the event that a standard model does not meet your surface preparation needs, we will develop a tailor-made blast machine concept for you.

Our team of experts welcomes your detailed questions and looks forward to helping you!

Operation

The loading device loads work pieces directly into the blast machine from containers, pallets or so-called charging baskets. The work pieces slide through the open loading door and onto the advancing caterpillar tread.

The loader subsequently returns to its initial position. The blasting process begins after the loading door is automatically closed and then locked. After the blasting period ends, the door opens automatically. The freshly blasted work pieces are removed in sequence by a take-off conveyor, or by emptying them directly into containers provided by the customer.

The blasting abrasive is continuously cleaned, recirculated and reused. An abrasive metering device feeds the cleaned abrasive from the abrasive storage bunker to the high-performance turbines.

A fan unit creates the partial vacuum necessary to maintain dust-free operation of the blasting unit. Extracted air is cleaned in a special filter unit.

Capabilities and applications

The tumble blast design has been recognized for decades as the most effective blasting process for removing scale, rust and burrs from mass production parts that require the rubber mill design found in our Model MG tumble blast machines. The tumble blast machine’s endless rubber mill continuously turns the work pieces and exposes them to the abrasive stream for the entire blasting time. The use of a rubber mill ensures a relatively gentle tumbling motion. Because clearances are kept small, it is also possible to blast extremely tiny work pieces.

Machines of this kind can be filled and emptied in a variety of ways. These include an automated loading device and take-off conveyor, manual loading and unloading in semi-automatic mode, hoisting equipment or direct unloading into containers provided by the customer.
