Drum Blast Machines
The AGTOS Product Range
To find the appropriate machine concept depends, amongst others, on the work pieces’ size, the required performance and on your concept regarding an ideal production process. If there is no way to find a solution using a standard machine, we will be very pleased to offer you a tailor-made machine concept. Please do not hesitate to send us your detailed enquiry. We will provide you with every information you may need.
Operating procedure of drum blast machines
The work pieces are in a normal box, which will be placed into a feeder or is directly emptied. The feeder will be lifted and arrives in front of the machine door, which opens immediately. Arriving at the right height, the feeder swings and unloads the work pieces into the drum. According to the sensitivity of the work pieces this process can be made with caution. The control can be made by PLC or manually. Through this, damage is avoided. At that time, the drum is in the loading position. Before the blasting process the machine door closes and the drum swings into an optimal position in front of the high performance turbine. Simultaneously, it turns around its own axis.
The blasting process starts and lasts as long as the work pieces are mixed and blasted from all sides. The interior of the blasting cabin is equipped with materials that are very resistant against abrasives. The primary wearing in the direct blasting zone of the high performance turbines is made of high-resistant, replaceable steel plates. During the blasting process the door keeps closed and could only be opened after the cabin has become dust-free. That takes around 10-15 sec. A slight low-pressure exhausts the dust during the blasting process. The dust will be separated in the appropriate filter unit.
After the blasting process the drum swings into the unloading position. At this position it is also possible to determine the quantity of the work pieces and the intensity of unloading by using a dosed emptying. The treated work pieces arrive on a screen conveying trough which separates the residual abrasive and transports the pieces to forthcoming boxes.
Capabilities and applications
It’s about highly modern machines according to a well-tried principle. Because of many new technical details the new AGTOS drum blast-machines are convincing. This unit type is very capable for treating bulk material. Compared with the widely-used band belt principle there are many important advantages:
Since the drum is made of one piece, crossings from flexible and fixed machine parts are avoided. I. e. clamping of work pieces is avoided. Furthermore, drums can easily and completely be emptied, that avoids double treatment of each work piece.
Due to wear resistance perforated manganese steel is used. The size of the holes depends on the dimensions of the work pieces as well as on the graining and the quantity of the effluent abrasives. Sophisticated devices are supporting the mixing of the work pieces.
