To minimize the production of dust when using a shot blasting machine, the following measures can be adopted:

Firstly, optimize the selection of shot materials. Use high-quality and regularly-shaped shot materials to reduce the dust resulting from the fragmentation of shot.

Secondly, improve the shot blasting process. Adjust parameters such as the shot speed, angle, and distance to make the collision between the shot and the workpiece more reasonable and reduce the dust flying.

Thirdly, install an efficient ventilation system. Set up proper ventilation outlets and exhaust devices in the working area of the shot blasting machine to promptly discharge the generated dust and treat it through filtering equipment.

Fourthly, conduct sealing treatments. Ensure that all components of the shot blasting machine are tightly connected, especially at the inlets and outlets for materials and observation windows, to minimize dust leakage.

Fifthly, adopt wet shot blasting. Spray an appropriate amount of water during the shot blasting process to increase the humidity of the dust and make it easier to settle.

Sixthly, equip with high-quality filtering devices, such as efficient bag filters or electrostatic precipitators, to enhance the filtering efficiency of the dust.

Seventhly, conduct regular cleaning and maintenance. Promptly remove the accumulated dust and debris inside the equipment to maintain its good operating condition and reduce the increase of dust caused by blockages and other issues.

Eighthly, pre-treat the workpieces. Remove large debris and loose attachments on the surface of the workpieces to reduce the amount of dust generated during the shot blasting process.

Ninthly, arrange the working time and workload reasonably. Avoid long-term continuous and high-intensity operations to reduce the accumulation and generation of dust.
