shot blasting and sand blasting machines

Power Blast Sand blasting and Shot blasting Machines are instantly recognisable by their unique spherical shape and can be found in operation the world over.

The standard range of blasting machines comprises of six sizes which are detailed in the chart below.

An additional range of specialised blasting machines have been developed for use with such materials as plastics which require high slope angles to ensure good flow characteristics.

Sandblasting and shot blasting are two different processes used for surface preparation. Sandblasting is a process of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth, roughen, shape, or remove surface contaminants. Sand blasting is also known as abrasive blasting and is used to clean, strip, or etch a surface. The process involves using a pressurized fluid, typically compressed air, or a centrifugal wheel to propel the blasting material against the surface. The most common materials used for sandblasting are sand, glass beads, and plastic media.

Shot blasting, on the other hand, is a process of using high-pressure air to blast small metal pellets onto a surface. It is also known as mechanical surface treatment and is used in various industries, including machinery, ship repair, auto parts, aircraft parts, and more. By projecting high-speed particles onto the surface of parts, shot blasting can remove impurities, enhance surface roughness, and even change welding tensile stress to compressive stress.
