Steel shot blasting

The main difference between aluminum shot blasting and aluminum sand blasting

The main difference between aluminum shot blasting and aluminum sand blasting

The main difference between shot blasting machine and sand blasting machine is the working principle

1. Blasting medium

The shot blasting machine shot the steel shot by the centrifugal force of impellers in high-speed rotation. 

But the sand blasting machine blasts the glass bead through the compressed air.

2. Energy consumption

Shot blasting machine feature is small energy consumption, and high working efficiency.

For the same working pieces, the energy consumption of shot blasting machine is only one-tenth of sand blasting machine and the shot blasting quantity of one set of 15KW shot blasting machine is equivalent to the sand blasting quantity of eight pieces 8mm caliber sand blasting machine.

3. Application

For the application fields, the shot blasting is in general fixed and it is not good to process the complex bore working pieces.

Sand blasting machine is flexible and it is convenient for the sand blasting machine to process the big working pieces or complex surface working pieces.

4. Processing

The sand blasting processing is sparing the abrasive at high speed to the surface of working pieces.

The purpose is to clean the surface oxidized layer and rust ETC to improve the quality of surface appearance. 

Shot blasting processing is shot blast the metalworking piece surface by hard particles (in general steel shot) at high speed, the purpose is to improve the fatigue strength of the metal surface.

5. Tools

The tools for both treatment processes are different and the medium is also different. 

The medium for both treatment processes can be recycled and reused. 

The above is the main difference between aluminum shot blasting and aluminum sand blasting.

    Thanks for making us understand the difference aluminum shot blasting and aluminum sand blasting machine. Useful blog it is. Keep sharing these posts.

  2. Comment *
    We need a line for shot blasting of aluminum profiles (maximum dimension 100x100mm, length 2750mm), using round stainless steel shot CHRONITAL with a fraction of S0.1-S0.2.
    Shot blasting allows you to get a matte surface on the aluminum profile and completely eliminate extrusion stripes on the surface of the anodized profile. Processing speed from 4 m.p. per minute
    Processing is needed only on the front side or L-shaped processing on 2 sides.
    360 degree machining is not required.
    Thanks in advance
