A wider treatment width allows for faster coverage of large road areas, reducing the overall time required for treatment. However, machines with wider treatment widths may be less maneuverable in narrow or confined spaces.

Blast Wheel Power

The power of each blast wheel is a significant parameter that affects the intensity of the shot - blasting process. The power of blast wheels can range from [E] kW to [F] kW. Higher - powered blast wheels can accelerate the abrasive media to higher speeds, generating a more powerful impact on the road surface. This is particularly important for removing tough contaminants and creating a deeper, more effective rough texture. The total power of all the blast wheels in the machine also contributes to the overall energy consumption and performance of the shot - blasting operation.

Abrasive Media Flow Rate

The abrasive media flow rate refers to the amount of abrasive media, such as steel shots or grits, that is fed to the blast wheels per unit of time. It is usually measured in kilograms per minute (kg/min) or cubic meters per hour (m³/h). The flow rate needs to be adjusted according to the condition of the road surface, the type of abrasive media used, and the desired treatment intensity. A higher flow rate can increase the coverage rate and the aggressiveness of the shot - blasting process, but it also requires more abrasive media and may increase the wear on the blast wheels and other components.

Machine Travel Speed

The machine travel speed is the speed at which the stone shot - blasting machine moves along the road surface during the treatment process. It is typically measured in kilometers per hour (km/h) or meters per minute (m/min).
