Steel crawler belt shot blasting machine for pakistani customer

Recently, QGMA Machinery has a set of steel crawler belt shot blasting machine delivery to Pakistan. Customer used the machine to clean some small castings, which after heat treatment with high temperature. The steel crawler belt shot blasting machine can not only remove the rust, oxide scale, sand after casting on the surface of the workpiece, but also reduce the internal stress of the workpiece and improve the fatigue strength of the workpiece. This machine can be used as a stand-alone machine or wired. The crawler-type shot blasting machine has a larger shot blasting volume and better sealing performance than previous cleaning equipment. The cleaning effect, production efficiency and dust removal effect are greatly improved, and the maintenance cost is reduced about 60%.

The brief introduction of steel crawler belt shot blasting machine.

The steel crawler belt shot blasting machine used to remove the sand, rust, oxide scale, burr on casting, forging, stamping surface. The machine suitable to clean the workpiece surface, which easy to rolling, not afraid to collision and the core not to deep. Some of tools plants, automobile plants, textile plants, heat treatment plants, casting plants and stamping plants are the mainly users of the machine. This kind of machine have the good protective measures, good shot blasting performance, the reasonable abrasive recycle system. It also have the good effective for the workpiece which are difficult to clean.

The steel crawler belt shot blasting machine has automatic fault detection device and adopts advanced Swiss GF technology, so that this machine has the characteristics of advanced structure, reasonable design, reliable operation and high production efficiency. The welding structure of the chamber system is composed of the chamber shell, the roof and the indoor protection. There is a screw conveyor at the bottom of the chamber shell, the inner part is equipped with a crawler belt and its transmission mechanism, the end is equipped with an end disc, the inner part is protected by a wear-resistant protective plate, and the top of the chamber is fixed with a shot blasting device.

In order to further develop the shot blasting device of the crawler shot blasting machine, it is necessary to analyze the shot blasting flow from the beginning of entering the feed system to the exit of the directional sleeve and then thrown by the impeller blades. As a leader in shot blasting technology, DISA has optimized the shot flow through the shot blasting machine and opened the way for a new next-generation shot blasting machine. It is the first company in the world to use high-speed photography technology to achieve such results. On the one hand, this uniform distribution significantly improves the energy utilization during the acceleration of the pellets. On the other hand, it also significantly improves the effectiveness of the abrasive flow on the surface of the workpiece. In the expanded area, density and coverage have also increased considerably.

The shot blasting device of the crawler shot blasting machine has a four-pole motor, a pulley, a belt, and a belt tensioning mechanism. The transmission belt adopts a conventional V-belt, which is convenient for maintenance and replacement. The blade of the shot blasting machine is fixed to the shot blasting machine through the shoulder on the blade. The shot blasting speed on the impeller disk can reach 83 m/min, and the speed of the impeller disk can reach 3000 rpm, which is 15-20% higher than that of ordinary linear blades.

The feature of the steel crawler belt shot blasting machine:

  1. Torsion-resistant, high-rigidity body shell.
  2. Reasonable chain drive system and geometric movement principle, which ensure that the sturdy, overlapping track shoes always maintain a smooth connection.
  3. High-quality cast chain links have undergone precise machining and partial carburization.
  4. The hardened and ground chain pins still have the smallest tolerance gap after long-term load operation.
  5. Advanced man-machine environment, easy to maintain:
  6. All bearings are installed outside the shot blasting chamber.
  7. All protective plates are installed in a modular manner, which is easy to disassemble and replace and ensures that the shell is not worn by the pill stream.
  8. The upper and lower positions of the material door are controlled by limit switches, and safety limit switches are monitored.
  9. The material door adopts an electric opening and closing door with a compact structure. It is lifted and lowered by the steel wire rope hoisted by the reducer, which is convenient to use, safe and reliable.
