Meijun 600 type rust blasting machine：
Subdivided into two categories: general pressure open sandblasting machine and pressurized open sandblasting machine.
The working principle of general pressure open sandblasting machine and the working principle of suction dry sandblasting machine similar.
It uses compressed air as the driving force of the open-type sandblasting machine, and the negative pressure formed in the spray gun through the high-speed movement of the air flow, the abrasive is sucked into the spray gun through the sand conveying pipe, and then After the acceleration of the compressed air, the abrasive is ejected from the nozzle and sprayed onto the surface to be processed to achieve the desired processing purpose.
In the suction type dry sandblasting machine, the compressed air is both the feeding power and the acceleration power of the jet.

The working principle of the pressurized open sandblaster is similar to that of the press-in dry sandblaster.
It is powered by compressed air, and the working pressure established by the compressed air in the pressure tank makes the The abrasive in the pressure tank and the compressed air are fully mixed and pressurized, and the abrasive is pressed into the sand conveying pipe through the sand discharge valve, and then accelerated by the compressed air, so that the abrasive is ejected from the nozzle and sprayed onto the surface to be processed to achieve the desired processing purpose.。
In the press-in dry blasting machine, the compressed air is both the feeding power and the acceleration power of the jet.
Pressurized open sand blasting machine adopts pressure feeding sand blasting (shot blasting) mechanism, namely The high-speed flow of compressed air in the high-pressure tank is used to form a high-pressure effect, and the sand in the high-pressure tank is pressed into the sand control valve. At the same time, another compressed air flow also enters the sand control valve, and accelerates the sand material entering the sand control valve, so that the sand material is ejected through the sand conveying pipe, and then sprayed to the workpiece surface at a high speed from the gun nozzle with the compressed air flow. , to achieve the purpose of cleaning the surface of metal workpieces and non-metal workpieces by sandblasting.

600 type pressure type rust blasting machine application：

When the Meijun open sandblasting machine is working, the compressed air and abrasive in the container are mixed and sprayed at the same time, so that the compressed air can be fully utilized, the air flow and the abrasive flow are easy to adjust, and the ideal mixing ratio can be obtained. It has low consumption of and abrasives, and high grinding and sweeping efficiency. It is suitable for large-scale cleaning and derusting of metal surfaces in shipbuilding, aircraft, rolling stock, machinery, bridges, chemical and other industries. Any need for metal surface cleaning and rust removal, mainly with this equipment and compressed air, can obtain satisfactory results.

600 type rust blasting machine application range:

一, Pretreatment: electroplating, painting, spraying, etc. are all covered by sandblasting before processing, the surface is absolutely clean, and at the same time, the adhesion and corrosion resistance of the covering layer are greatly improved.

二、Cleaning: removal of oxide skin, residue and dirt from metal workpieces such as castings, stamping parts, welding parts, and heat-treated parts; surface cleaning of non-metallic products, removal of black spots on the surface of ceramic blanks and restoration of paint patterns, etc.
3. Refurbishment of old parts: refurbishment and cleaning of all moving parts such as automobiles, motorcycles, and electromechanical equipment. At the same time, the fatigue stress is eliminated and the service life is prolonged.
4. The surface traces of all metal products and non-metal products (plastic, crystal, glass, etc.) are eliminated, and the surface of the product is treated with argon light to improve the grade of the product surface.
5. Mold treatment: Argon light matte treatment on the mold surface, graphic production, and mold cleaning, do not damage the mold surface and ensure mold accuracy.
Sixth, burr processing machined parts to remove tiny burrs, injection molding parts to eliminate plastic overflow burrs.
7. Rework of defective products: Removal of defective covering layers of products, removal of poor surface coloring and printing.
8. Strengthen the surface hardness of metal parts and eliminate stress, such as surface treatment of aircraft blades, springs, machining tools and weapons.

九、Etching and anti-skid processing: metal products, non-metal products surface etching patterns, text and anti-skid treatment, such as: marble, anti-skid handles, seals, stone inscriptions, etc. Scrub, whitish and whiskering effects on denim are achieved.
