Chain hanger shot blasting machine

Types of chain hanger shot blasting machines

A chain hanger shot blasting machine comes in different variants, each tailored to specific needs. The hopper type is the most common design. It has a blast wheel positioned in a horizontal cabinet before an intake hopper. The blast wheel is fed by a hanger and roller conveyor combination. The pendulum hangers travel horizontally through the intake hopper. Once the pendulum bypasses the hopper's vertical section, the items are blasted by the rotating wheel. Another option is to use tumbling boxes or barrels. Instead of a conveyor chain, items are blasted by Ballistics blasters in enclosed boxes or barrels that tumble during the blasting process.

The vertical belt shot blasting machine has its blasting wheel vertically aligned. Belts are used as cargo carriers. It is also referred to as the conveyor approach. Vertical belt machines are more compact than horizontal belt machine variants, saving a lot of floor space. Apart from requiring less space, vertical belt ones have the added advantages of blasting bigger workpieces and better cleaning efficiency. Nonetheless, they may incur higher maintenance costs. The chain plate blasting machine is similar to the belt one. However, instead of a belt, it uses plates to carry workpieces. The plates are used to convey irregularly shaped workpieces.

Cross-rail shot blasting machines are used to clean the underside and other parts typically not accessible by other machines. The cross rails blast steel shots horizontally. They are perfect for cleaning small parts. A table blast machine has a turntable in place of the hanger to hold the workpiece. It rotates, exposing the workpiece to the steel shots from the blast wheel. The machine is mostly used to clean flat workpieces.

Specification and maintenance of chain hanger shot blasting machines

Specifications for chain hanger shot blast machines vary depending on design and architecture. Down is a list of some key specifications for blasting machines.

• Hanger Size

  The size of the machine depends on the size of the workpiece to be blasted. Larger machines can handle bigger workpieces. For example, a 2,000 mm micron workpiece requires a machine that is just about this dimension.

• Media Handling System

  A machine with 30,000 to 40,000 kg of steel shot will have a media handling system that can efficiently transport this volume of steel shot to and from the blasting cabinet.

• Dust Extraction System

  This system is important for collecting the dust from the blast operation. The power and efficiency of the dust extraction system will impact the size of the dust that can be collected from the chain hanger. The filter must be able to cope with the fine dust that results when blasting with various media.

• Control System

  The control system determines how many stations there are and what the automation level is. In a machine with two blasting stations, there will be one loading/unloading station and two shot blast pressure and exposure zones.

Maintenance

When well taken care of, chain hanger shot blast machines offer many years of solid performance and reduce workpiece preparation costs per unit. Regular machine inspection helps to keep it in top shape. During inspections, look for any signs of wear or damage. Do this for all major parts: the steel structure or hanger, the conveyor chain, the blasting wheel, the impeller, the separator and dust collector, the filtration system, the hopper, and the blasting guns. Replace faulty parts immediately to maintain machine efficiency and work safety.

With part inspections, it is easier to find areas that require lubrication or adjustment, which is vital to the smooth working of the machine. Cleaning is also crucial. An efficient filtration system will prevent dust from accumulating in the machine. This helps to maintain the blast media's integrity and the purity of the air within the machine.

Do routine cleaning of all exposed and internal parts of the chain hanger. This keeps the machine free from any dust or debris build-up that could reduce its performance or pose a fire hazard. Waste material build-up near parts that get very hot can become a fire hazard. Use the operation manual as a guide during the cleaning process. It will specify the required cleaning process and the most important parts to prevent contamination from transferring blasting media.

Scenarios of chain hanger shot blasting machines

Industry/application scenarios of chain hanger shot blasting machines:

• Aerospace industry: The aerospace industry uses chain hanger shot blasting devices for surface cleaning and polishing of aircraft components such as landing gears and engine housings. This ensures components are free of impurities, promoting stronger and more reliable aircraft structures. Equally important, the surfaces of these components can be improved to increase the adhesion of coatings and enhance their performance.
• Shipbuilding industry: In the shipbuilding industry, chain hanger shot blasting machines are used for cleaning the surfaces of steel plates, sections, and pipes and for derusting and roughening of hull structures, decks, and ocean-going pipes. This ensures the ship's hull and other structures are free from rust and oxide layers, making for better quality welding and coatings.
• Automotive manufacturing: Chain hanger shot blasting machines are commonly used for body and chassis components in automotive manufacturing. They clean and remove burrs from alloy wheels, improve the quality of welding points, and enhance the adhesion of coatings on the body and chassis components. This improves the overall quality and durability of the automotive products.
• Machinery manufacturing: In machinery manufacturing, chain hanger shot blasting machines are used for cleaning and repairing casting and forging parts such as gear boxes, brackets, and pumps. The blasting process removes sand, oxide scales, and surface defects, which improves the accuracy and performance of machine components.
• Oil and gas industry: The oil and gas industry uses chain hanger shot blasting machines to treat the surfaces of pipelines, valve parts, and pump housings. The equipment removes rust, scale, and impurities, ensuring the reliability and leak-proof performance of oil and gas transport and equipment.
• Tool manufacturing: In tool manufacturing, chain hanger shot blasting machines are used for surface hardening and cleaning of tools such as punches, drills, and saw blades. The blasting treatment improves tool wear resistance and extends tool life, ensuring precision and durability of the tools.

How to Choose Chain Hanger Shot Blasting Machines
