Crawler vs Hook Shot Blasting Machine: Differences and Selection Guide

In the application of shot blasting machines, track type and hook type are the two most widely used types. Both types of shot blasting machines achieve rust removal, strengthening and other functions by shooting steel balls, but there are significant differences in structural design, applicable scenarios, etc., which directly affect the production efficiency and cleaning effect of users. Below, the editor will introduce the differences and distinctions between track type shot blasting machines and hook type shot blasting machines, and how to choose them.

This model mainly uses enclosed tracks as the conveying carrier, and the workpiece rolls and flips with the tracks. The pellets are evenly sprayed from multiple angles, and can be processed in all directions without manual intervention. Its compact structure and small footprint make it suitable for batch processing of small, irregular workpieces such as fasteners, stamped parts, and small castings.

This model uses a lifting and rotating hook to suspend workpieces. The workpieces rotate in a closed compartment while receiving projectile impacts, providing a larger working space and capable of handling large, heavy, or structurally complex workpieces such as machine tool beds, large castings, steel structural components, etc.

The tracked shot blasting machine has a high degree of automation, which can achieve continuous feeding and discharging, and has obvious advantages in batch processing efficiency. There are no hanging marks during the rolling process of the workpiece, and the surface treatment is more uniform.
Hook type shot blasting has stronger intelligence and activity, and can adjust the height and rotation speed of the hook according to the size of the workpiece. It is suitable for processing single batches and large-sized workpieces, and is also convenient for targeted shot blasting of specific parts of the workpiece. However, manual loading and unloading are required, and the operation rhythm is relatively slow.

Priority should be given to track type for small and medium-sized batches, as well as small irregular workpieces; For large quantities, large/heavy workpieces, the hook type is preferred.
