For complex construction work, special equipment is often used. So, sandblasting machine is necessary for abrasive processing and grinding of various materials. Some models are excellent at removing old rust or used to polish some surfaces. Before buying such equipment, pay attention to the following types of sandblasting machines. In addition to the technical characteristics, you should not forget about the goal.
Suction technology
In such a machine, air is used not only as a basis for an abrasive water jet. In some cases, the air flow will push material from the container directly to the nozzle. This whole procedure takes place without additional pressure. This technique is used for grinding and matting glass, removing paint, stubborn dirt.
Vacuum equipment
Such a sandblasting machine to buy is quite real. It is often used for cleaning floor coverings or areas where important installations or devices are located. The essence of this technology is to feed the abrasive to the working surface. Grains of sand or other material fall onto the coating and are then swept up by the air blast. Thus, grains of sand are in constant circulation. This method allows you to delicately handle large areas without damaging important equipment.
Pneumatic plants
Such equipment is powerful enough. Pneumatic sandblasting is needed for removing chemically resistant formations, as well as grinding difficult metal parts. They are often used for cleaning roads, bridges and supporting structures.
