Dual-head shot blasting design: Improves cleaning efficiency per unit time while ensuring uniform surface texture, avoiding missed areas or over-blasting.

Variable frequency speed control walking system: Allows flexible adjustment of travel speed according to the substrate condition, and, in conjunction with the gate alarm function, maintains stable operation on slopes or complex terrain.

High-efficiency shot separation system: Effectively separates steel shot and dust using airflow and gravity principles, achieving high recovery rates and reducing material loss and construction costs.

Wear-resistant construction: The entire machine is constructed from high-strength wear-resistant materials, and core vulnerable parts undergo special processing to extend service life and reduce downtime for maintenance.

Typical application scenarios:

Substrate cleaning before bridge deck waterproofing layer construction;

Texture restoration of cement and asphalt pavements;

Removal of old coatings and surface roughening of industrial floors;

Pre-treatment for corrosion protection of metal surfaces such as steel structures, ships, and storage tanks;

Substrate preparation before colored paving or landscape pavement construction. This machine is easy to operate and maintain, and is one of the mainstream medium-sized shot blasting equipment on the market. It is especially suitable for projects with high requirements for construction quality and environmental protection.
