What is the difference between a sandblasting machine and a shot blasting machine?

Sandblasting machine and shot blasting machine are two common surface treatment equipment, their role is to remove dirt, oxide, rust and so on on the surface of the object through impact or spraying particles, so as to achieve the effect of surface smoothing, enhancing adhesion and improving corrosion resistance. The main differences between them are in the following aspects:

1.The cleaning method is different: the sandblasting machine cleans the surface of the object by spraying the sand shot with sand particles in the high-speed jet air stream, while the shot blasting machine cleans the surface by throwing metal particles such as small iron balls onto the surface of the object by rotating the wheel disc at high speed.

The sandblasting machine is simple to operate, has a wide cleaning area, and can be used for surface treatment of objects of various sizes; The shot blasting machine is suitable for surface cleaning of large objects, but it has high requirements for operators.

2.The cleaning effect is different: because the size of the sand particles used in the sandblasting machine is different, it cannot be well guaranteed in the cleaning effect, while the shape and size of the metal particles used in the shot blasting machine are standardized and unified, so the cleaning results are more consistent and more powerful.

3.The scope of application is different: the sandblasting machine can handle a wide range of object types, and can be used for the surface treatment of steel structures, concrete, wood and other materials. The shot blasting machine is mainly suitable for the cleaning of hard materials such as steel, castings, automobile parts, and pressure vessels.

In general, sandblasting machines and shot blasting machines have their own advantages and scope of application. When choosing which equipment to use, you need to consider factors such as the material, shape, and size of the object to be cleaned up to achieve the best cleaning results.

Sandblasting machine and shot blasting machine are two different types of surface rust removal equipment. Sandblasting is powered by compressed air, which carries sand (corundum, corundum, etc.) to impact the surface of the workpiece; The shot blasting machine uses an electric high-speed impeller to throw steel shot to impact the surface of the workpiece; The materials used on the surface of the two impact workpieces are different, the sandblasting is made of high-hardness wear-resistant materials such as corundum and emery, and the shot blasting is made of various special materials and shapes of metal particles (called shot blasting).

The sandblasting machine needs to use gas, and the air consumption is relatively large! The shot blasting machine uses a motor, no gas! There are differences in use, so choose the right way according to the requirements!

The differences between sandblasting and shot blasting are as follows:

1. Different forms: shot blasting is obtained by mechanical methods to obtain high-speed and long-distance projection onto the surface of parts, and sandblasting is a method of using compressed air to blow out quartz sand at high speed to clean the surface of parts.

2. Different functions: shot blasting is mostly used in the pretreatment of steel plate (rust removal before painting), and the effect of sandblasting is to remove the old paint and rust on the steel plate and re-coat.

3. Shot peening has a strengthening effect on the workpiece, and the sandblasting is not obvious.

4. The substances used are different: generally shot blasting is a small steel ball, and sandblasting is quartz sand.

The role of sandblasting:

Sandblasting is powered by compressed air to form a high-speed jet beam to spray the sprayed material (copper ore, quartz sand, emery, iron sand, sea sand) to the surface of the workpiece to be treated at high speed, so that the appearance or shape of the surface of the workpiece changes.

Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, so the fatigue resistance of the workpiece is improved, the adhesion between it and the coating is increased, the durability of the coating film is prolonged, and it is also conducive to the leveling and decoration of the clear rock of the coating. <>

Main Differences Between Shot Blasting and Sandblasting:

1.Shot blasting is the use of a high-speed rotating impeller to throw a small steel shot or a small iron shot out to hit the surface of the part at high speed, so the oxide layer on the surface of the part can be removed. Sandblasting is a method of using compressed air to blow quartz sand out at high speed to clean the surface of parts.

2.Generally, shot blasting is used for regular shapes, etc., and several throwing heads are up and down, left and right together, with high efficiency and low pollution. Sandblasting is used for complex shapes, easy to remove rust by hand, the efficiency is not high, the site environment is not good, and the rust removal is uneven.

3.In the repair and shipbuilding industry, shot blasting (small steel shot) is mostly used in steel plate pretreatment (rust removal before painting). Sandblasting (ore used in repair and shipbuilding industries) is mostly used in forming ships or sections, and the role is to remove the old paint and rust on the steel plate and recoat it.

4.Shot blasting is to use a motor to drive the impeller body to rotate, relying on the action of centrifugal force, the diameter of the pill (there are cast shots, cut shots, stainless steel shots, etc.) to the surface of the workpiece, so that the workpiece becomes beautiful, or change the welding tensile stress of the workpiece to compressive stress, improve the service life of the workpiece. Sandblasting is in the steel structure, the application of high-strength bolts for connection is a relatively advanced method, because the high-strength connection is the use of friction between the joint surface to transmit force, so the quality of the joint surface is very high, then the joint surface must be treated with sandblasting.

Throwing the ant Kai holding pill machine.

It is a small steel shot that uses a high-speed rotating impeller.

Or the small iron shot is thrown out to hit the surface of the part at high speed, so it can be muffled to remove the oxide layer on the surface of the part.

Shot blasting machine is a method of using compressed air to blow out quartz sand at high speed to clean the surface of parts.
