Trolley-type shot blasting machines are suitable for cleaning and strengthening the surfaces of large and medium-sized steel structures and castings, as well as for removing rust and scale from thick steel billets. They are widely used in industries such as casting, forging, and machinery. The trolley not only carries the workpiece but also rotates on its own, allowing for comprehensive and effective cleaning of the workpiece, requiring only a single cleaning chamber. For workpieces with complex structures, manual shot blasting can be used to clean blind spots after shot blasting, ensuring a thorough cleaning of the workpiece.
▶ Product Structure
Trolley Conveyor System
The trolley conveyor system is a core component of a trolley-type shot blasting machine. It uses a trolley to transport workpieces from the feed inlet into the cleaning chamber, rotating or translating the workpieces during the cleaning process. The trolley is typically equipped with multiple workpiece suspension devices, allowing for flexible adjustment to accommodate workpieces of varying sizes and shapes. The conveyor system ensures uniform contact of the workpieces with the shot blasting medium during the cleaning process, resulting in efficient surface cleaning.
Shot Blaster
The shot blaster is the core operating unit of a trolley-type shot blasting machine. Its high-speed impeller accelerates and ejects steel shot onto the workpiece surface. The number and layout of the shot blasters are typically adjusted based on the size of the workpiece and the cleaning requirements to ensure uniform surface cleaning. Each shot blaster can independently adjust its speed and spray angle to meet the needs of different cleaning tasks.
Cleaning Chamber
The cleaning chamber is the area where the workpiece and shot blast come into contact. It is typically sealed to prevent shot blasting from flying. The surfaces within the cleaning chamber are constructed of wear-resistant materials to withstand the impact of shot blasting from the blasters, extending the service life of the equipment. The design of the cleaning chamber ensures uniform cleaning of all parts of the workpiece, eliminating blind spots.
Shot Recovery System
During the cleaning process, shot is gradually consumed. The recovery system extracts the used shot from the cleaning chamber, cleans it, and then recycles it for reuse. This system is typically equipped with a screening device to remove unqualified shot, ensuring consistent cleaning results. This system not only effectively reduces shot consumption but also lowers production costs.
Electrical Control System
The trolley-type shot blasting machine is equipped with an advanced electrical control system that precisely controls operating parameters such as the shot blasting wheel speed, shot flow rate, and trolley transport speed. The operator can easily set different cleaning parameters through the control panel. The automated operation process reduces manual intervention and improves production efficiency.
Dust Removal System
The equipment is equipped with a highly efficient dust removal system to remove dust and impurities generated during the shot blasting process. Utilizing powerful suction and a multi-stage filtration system, the dust removal system effectively cleans the interior of the equipment, reducing environmental pollution and ensuring long-term stable operation.
▶ Advantages
Efficient Cleaning
Trolley-type shot blasting machines efficiently and thoroughly remove impurities such as oxide layers, rust, and grit from workpiece surfaces. The trolley transport system ensures that workpieces are fully exposed to the blast media during the cleaning process, ensuring that every surface is effectively treated.
High Adaptability
Trolley-type shot blasting machines are suitable for a wide variety of metal workpiece types and sizes. The trolley transport system flexibly adapts to workpieces ranging from small components to large castings and forgings. Furthermore, the number and angle of the shot blast wheels can be adjusted to meet specific workpiece requirements, meeting diverse process requirements.
Energy Saving and Environmental Protection
This machine is equipped with an efficient steel shot recovery system that cleans, screens, and recycles used steel shot for reuse, reducing steel shot consumption and lowering production costs. Furthermore, the dust removal system effectively removes dust and impurities, minimizing environmental pollution and meeting modern environmental standards.
High Automation, Minimizing Manual Intervention
The trolley-type shot blasting machine utilizes an intelligent control system, boasting a high degree of automation. Through a simple user interface, operators can easily adjust various parameters, allowing the machine to automatically complete the workpiece cleaning process, significantly improving production efficiency and reducing manual operation.
Improving Workpiece Quality
The shot blasting process significantly improves the surface roughness of workpieces, which is crucial for subsequent spraying, painting, and other processes. Furthermore, the cleaned workpiece surface removes microcracks and surface defects, improving fatigue resistance and corrosion resistance, and extending its service life.
Extending Equipment Life
The trolley-type shot blasting machine's wear-resistant design and shot recovery system effectively reduce equipment wear and failure, extending its service life. Furthermore, the well-coordinated trolley transport system and dust removal system ensure long-term stable operation.
