Shot blasting and sand blasting have their own advantages and disadvantages, and shot blasting is usually better in terms of thoroughness.
Advantages of shot blasting rust removal Thoroughness: Shot blasting rust removal projects steel shots onto the surface of the workpiece at high speed through a high-speed rotating shot blaster, which can more thoroughly remove rust and scale, especially suitable for the dead corners of the inner cavity that are difficult to clean, and achieve a higher degree of cleanliness and roughness. Efficiency: Shot blasting rust removal has a high degree of mechanization and high efficiency, and is suitable for the rapid processing of a large number of workpieces, especially for the processing of steel structures, small hardware and other products. Environmental protection: Compared with sand blasting rust removal, shot blasting rust removal is more environmentally friendly because less dust is generated during the shot blasting process, reducing environmental pollution. Advantages of sand blasting rust removal Flexibility: Sand blasting rust removal uses compressed air as power, which is flexible to operate and suitable for workpieces of various shapes and sizes, especially those that are difficult to process mechanically. Surface treatment effect: Sand blasting rust removal can better control surface roughness and precision, and is suitable for workpieces that require fine processing. Cost: Sandblasting rust removalequipment is relatively simple and low cost, suitable for small batches or manual operations.
