Mesh belt shot blasting machine

Types of mesh belt shot blasting machines

Mesh belt shot blasting machines, which are also called mesh belt shot peening machines, are a type of shot blasting machine with a flexible and durable steel belt. It can change the surface treatment of various types of workpieces. They are usually used to clean, strip, or decarburize the surface of metallic workpieces like castings, forgings, welds, and more. Generally speaking, mesh belt shot blasting machines can be divided into three main types: standard type, super turbine type, and combination type.

• Standard mesh belt shot blasting machine:

Standard mesh belt shot blasting machines are the most common types. They usually have a standardized machine frame. Inside the frame, there is a heavy-duty mesh belt that can withstand high temperatures and weights. It is usually made of metal plates and is specially designed to hold workpieces like metal parts, castings, and car wheels. Steel shots or grits are blasted onto the surface of the workpieces by the impellers through the blasting nozzles. The blasted residue and abrasives will fall onto the lower hopper through the vibrating screen on top, and the workpieces will be removed from the machine through the mesh belt.

Super turbine mesh belt shot blasting machines are equipped with special turbines. They usually consist of an impeller hub, a disc, and several blades. The blades are made of high-strength alloy materials, and their design and angle can be adjusted according to customers' unique needs. The special turbine in this kind of shot blasting machine can increase the cleaning speed by about ten times. The efficient energy conversion increases the speed at which steel shots or grits strike the surface of workpieces. Therefore, it shortens processing time. Super turbines can eliminate the same level of oxide scales and rust faster than regular turbines, making them a great improvement in productivity.

Super turbine mesh belt shot blasting machines are generally used in large-scale industrial production lines and intense surface treatment tasks.

Combination mesh belt shot blasting machines are versatile pieces of equipment. They usually integrate different functions and features by combining various components. For example, the combination may include a standard mesh belt shot blasting machine and a conveyor system. The transportation speed of the conveyor system can be adjusted to meet the requirements for different surface treatment tasks. Additionally, other facilities, such as dust collection systems, can also be integrated into the machine to collect and filter dust and other hazardous waste during the blasting process, helping improve work safety and environmental protection.

Combination mesh belt shot blasting machines are always custom-made to meet specific industrial requirements. They are suitable for large-scale production, complex processing, and multi-functional industrial applications.

Specifications and maintenance of mesh belt shot blasting machines

Here are some key specifications of the machine and a brief summary of its maintenance requirements.

• Payload: The payload is the maximum weight the belt can carry. It typically ranges from 50 kg to 500 kg, but it may be higher or lower, depending on the specific machine model.
• Blast wheel: This refers to the number and size of the machines' wheels that shoot abrasive at the object. Machines usually have between 1 to 6 blast wheels, with each wheel measuring about 150 to 400 mm in diameter.
• Surface Coverage: This describes the amount of area an abrasive wheel can cover per minute. The surface coverage depends on the number, size, and rotational speed of the blasting wheels. It typically ranges between 2,000 to 5,000 square mm/min.
• Abrasive Flow: This refers to the quantity of abrasive material that flows through the machine per minute, typically measured in kilograms per minute. The abrasive flow may range from 50 to 500 kg/min, depending on the machine type and adjustment settings.
• Power: The power rating of an average mesh belt shot blasting machine is between 5.5 KW to 50 KW. This is for the induction motor driving the abrasive delivery system.

Maintenance

Users of the machine must perform regular checks to ensure it works properly. Focus on the following parts with maintenance requirements:

• Blast wheels: Inspect the wheels and their connecting parts at least twice weekly. Look out for signs of damage, wear, or loose connections. If users discover any issues, they should immediately carry out repairs or replacements to avoid more serious machine breakdowns.
• Abrasive separator: This part of the machine requires more frequent maintenance visits. The abrasive separator should be checked every day before the machine is put to use. Ensure it is not obstructed by abrasive build-ups. If there is a blockage, clear it immediately to allow for proper abrasive recycling and separator functioning.
• Dust collector: While the dust collector must be inspected weekly, it may require more frequent visits if the meshes of the workpieces being processed are fine. During inspections, ensure the dust collector filter is clean and not blocked. Users should carry out filter cleaning or replacement whenever necessary to maintain optimal dust extraction efficiency.

Uses of mesh belt shot blasting machines

Because of their effectiveness and flexibility, mesh belt shot blasting devices are employed in a very wide range of sectors and applications.

• Automobile production facilities utilize machine models to clean the body and car components. The surfaces of the vehicle's bodies and components are descaled, buffed, and cleaned with the help of these machines. They help prepare for superior paint adhesion after getting rid of the impurities and oxidation on the surface.
• Steel production, where large and solid steel materials and structures are present, uses a heavy-duty steel shot blasting machine. This machine ensures a uniform and smooth surface for all parts. It also enhances the steel's ability to bond with other materials at the same time.
• The aviation industry can also use the steel shot blasting machine for steel. Components like the frames of aircraft are easily handled by this machine. It smoothens and polishes the surfaces of complicated metal parts, which improves both their structural integrity and their weight-to-strength ratio.
• The steel tube mesh belt shot blasting machine is made specifically for handling steel tubes. It efficiently treats the surfaces of steel pipes, removing scale, rust, and burrs. It also improves the adhesion of coatings. Basically, it significantly ensures that the steel pipes are in good condition whenever they are used or taken care of.
• General metal surfaces can be treated with the help of the special-purpose metal shot blasting machine. No matter how intricate the metal piece or material is, this kind of machine can easily reach and treat it. It gets rid of the dirt, oxidation, and other contaminants from the metal surfaces. The parts get through blasting, which improves surface features like grip or roughness. Machines of this type are ideal for precision cleaning and surface preparation.
