1. The shot blaster of shot blasting machine manufacturers is installed on the main shaft driven by an electric motor. During operation, the projectiles flow into the shot blaster through the projectile inlet pipe. The spiral plate heat exchanger and the pill distributor rotating synchronously with the blades give the projectiles an initial velocity. The projectiles fly out through the window of the directional sleeve and are thrown onto the high-speed rotating blades outside the directional sleeve. After being further accelerated by the blades, they are thrown onto the surface of the workpiece to be cleaned, so as to achieve the cleaning effect.

2. A dust collector is a vacuum cleaner used to collect waste, filter and purify air, and clean the environment in industrial production processes. It can absorb various granular dirt and liquids such as metals, non-metals, oil, water, etc., and can also absorb toxic and harmful gases.

3. A hoist is a mechanical equipment that transports materials by changing potential energy. It usually refers to large mechanical equipment with high power and strong lifting capacity.

The accessories of shot blasting machines are wearing parts with a service life of about 600 hours, which need to be replaced every 2-3 months, and the service life of dust removal filters is about 6 months.

Shot blasting machines are mainly used for shot blasting derusting before painting of bulldozers, road rollers, loaders, and structural parts, removing welding slag, oxide scales and other dirt, and obtaining a certain rough clean metal surface. Using this machine for shot blasting cleaning can bring the following benefits: improve the surface decoration and internal quality of products, bringing new business opportunities for shot blasting machine manufacturers; the workpieces after shot blasting cleaning can obtain a certain roughness and a uniform clean metal surface, improving the corrosion resistance of mechanical products and metal materials; remove the internal stress of welded structural parts, improve their fatigue strength and extend their service life; increase the adhesion of the paint film, improving the decorative quality and anti-corrosion effect of workpieces; the shot blasting machine realizes the PLC automatic cleaning mode, which greatly improves efficiency and reduces the labor intensity of cleaning work.

How to ensure the expected effect of shot blasting cleaning by shot blasting machines?

Many people may have doubts. In fact, cast iron parts are not only cleaned by shot blasting. For relatively large items, the sand must first be cleaned in a barrel. The risers of cast iron parts are removed and then rolled in the barrel.

Before shot blasting, the spare parts collide with each other in the barrel, removing most of the sand on the surface. Scientific research shows that in terms of damage, the tensile stress on the surface of metal composite materials is much easier to cause damage than the compressive stress. When the surface is under compressive stress, the fatigue life of the material is further improved. Therefore, when parts such as shafts that are prone to cracking have surface pressure, shot blasting is usually used to extend the service life of the goods. In addition, metal composite materials are very sensitive to tensile stress, which means that the tensile strength of the material is much lower than the reduced compressive strength. This is because tensile strength (compressive strength, compressive strength) is usually used to represent the performance of metal composite materials. The running surface of steel plate vehicles that people often take can significantly improve the fatigue performance of the material and extend the service life of the vehicle.

Shot blasting derusting uses an electric motor to drive the centrifugal impeller to rotate, and the projectiles are thrown under the action of centrifugal force, so that the surface of the steel parts can reach a certain surface roughness, making the steel parts firm and durable, or converting the welding tensile stress of the steel parts into compressive stress, thereby improving the service life of the steel parts.

It is basically used in general industrial fields of mechanical equipment, such as maintenance, shipbuilding, auto parts, airport parts, large guns, canned meat, ground roads, bridges, steel structures, laminated glass, thick steel pipes, etc. Shot blasting equipment can remove rust and dirt on steel parts. The purpose is to prepare for the next step in advance. It is necessary to ensure the surface roughness and surface consistency of the next process.
