Combining domestic and foreign technologies, it is a cleaning equipment with good cleaning effect, compact structure, low noise, and is used for surface rust removal or shot blasting strengthening in large and medium-volume production. It has the following characteristics:
1. It adopts cantilever centrifugal shot blasting machine, which has the characteristics of long service life and simple structure;
2. Three projectile speeds of 75 m/s, 80 m/s, and 85 m/s are used.
3. The pulley adopts the internationally advanced quick-change structure, which is beneficial to improving production efficiency and reducing labor intensity.
4. The BE type separator is used, which has good separation effect and high productivity, and has a positive effect on improving the blade life;
5. Using bag dust collector, the dust emission concentration is lower than the national standard, which improves the working environment of workers;
6. This model adds some special mechanisms such as manual pill splitting gate and discharging door.
7. This type of crawler shot blasting machine can be used as a stand-alone machine or with wiring.

Structure and principle
This machine is a small cleaning equipment, mainly composed of a cleaning room, shot blaster assembly, elevator, separator, electrical system and other parts.
Working principle: Add a specified number of workpieces to the cleaning room. After the machine is started, the pellets thrown away at high speed form pill-lines, and hit on the surface of the workpiece evenly, thereby cleaning and strengthening them. The thrown projectiles and sand particles flow into the elevator and are lifted by the elevator to the separator for separation. The dust is sucked by the fan to the dust collector for filtration, and the clean air is discharged into the atmosphere. The dust on the cloth bag is mechanically vibrated and falls into the dust collecting box at the bottom of the dust collector. The user can clean it regularly. The waste sand flows out from the waste pipe, and the user Can be reused. The shot-sand mixture is taken back into the chamber through the recycling pipe, and is reused after being separated by the separator. The clean shot enters the shot blaster through the electromagnetic shot supply gate to hit the workpiece.

Crawler-type shot blast cleaning machine is suitable for surface cleaning of various parts. It can be used to clean the sand on the surface of various metal castings, remove rust from the surface of ferrous metal parts, blunt the surface and burrs of stamping parts, surface treatment of forgings and burr heat treatment workpieces, remove oxide scale on the surface of springs and refine the surface grains, etc. This is achieved through the shot blasting strengthening process of this series of equipment. Its application range is extremely wide, mainly including foundries, heat treatment plants, motor factories, machine tool parts factories, bicycle parts factories, power machine factories, auto parts factories, motorcycle parts factories, non-ferrous metal die-casting factories, etc. The workpiece after shot blasting can obtain a good material quality, and can also be a precursor to blackening, bluing, passivation and other processes on the surface of metal parts. At the same time, it can provide a good base surface for electroplating and paint coating. After the workpiece is shot blasted by this machine, the tensile stress can be reduced and the surface grains can be refined, thereby strengthening the surface of the workpiece and increasing its service life.
