TECHNICAL BROCHURE Tumble Belt Cleaning Machines with one and two turbines Tumble belt shot blasting machines are the most universal among all shot blasters as their design makes them suitable for processing parts of different sizes in bulk loads. Cym Materiales SA manufactures two groups of tumble belt machines. The blasting units belonging to the first group are rather small with one turbine and a shot capacity range of 20 to 60 liters while the second group has two turbines and a shot capacity from 130 to 900 liters. These types of tumble belt shot blasting machines are very easy to operate. The process starts with the loading of the parts on the belt either manually or through an automatic loading system. Once the door is closed the blasting cycle initiates. The wheels and the belt start spinning producing a continuous rotation of the parts ensuring that all components are exposed to the shot blasting stream for consistent cleaning. When the blasting process finishes, the machine stops automatically allowing the unloading of the parts to take place. Then, the operator moves the belt in the reverse direction to prepare the machine for a new load. CYM MATERIALES SA www.cymmateriales.com.ar // info@cymmateriales.com.ar

Lower production costs by using 2 turbines Usually, complaints such as blasting times not being able to be reduced are often heard from those who operate tumble belt cleaning machines, specially from those whose equipment's size is big and have only one wheel for blasting . On the other hand, when time is reduced the quality of blasting is not homogeneous. Eventhough in the center of the cargo the components are successfully blasted, those, which are set in the extremes next to the discs, are not. The distribution in the blasting stream that is propelled by a turbine is not even, since most...

Obtained results With the results from this test we came to the following conclusions: The best option to improve the rubber belt machines is to use two turbines. If both turbines have the same installed power as those machines that have only one, a better distribution of blast can be obtained. Moreover, another positive aspect is the effect achieved by treating the parts from different impact angles, improving the uniformity of the blasting that could not be achieved with the old one-turbine model.

Conclusion Every model needs the appropriate placement of the turbines to prevent the streams from crushing against each other and to achieve the best performance possible. Some of the advantages of working with two turbine tumble belt machines are listed below: • Blasting time reduced between 40% and 50% with similar installed power. Maintenance costs reduced by better exploitation of the equipment. Amount of blast consumption reduced by finished part. Electric consumption reduced by blasted part. Working costs reduced. More homogeneus quality of the parts. Modifications for old tumble...
