Types of Double Hanger Shot Blasting Machines

A double hanger shot blasting machine, also known as the double-point shot blast machine, is a kind of shot blasting machine that has two hangers to increase the efficiency of the production line of the shot blasting process. The double hanger can blast two workpieces in two different areas at the same time. It consists of a blast wheel, a control cabinet, a drive motor, a separator, a blasting chamber, a hanger, a door, a blast media, etc. As a piece of highly efficient equipment in the shot peening market, it is applied to various surfaces of castings, workpieces, and steel frames.

Double hangers can be made from different materials. The commonly used materials for double hangers include carbon steel, stainless steel, and alloy steel. Carbon steel is frequently chosen because of its cost-effectiveness. Alloy steel is also sturdy, and its service life is longer. Stainless steel is corrosion-resistant.

Double hanger shot blasting machines can be made in different sizes to meet the customer's needs. They also come in different types to suit various industries.

• QL-DBH: This kind of machine has a hanger of a bucket shape. It can blast large steel or iron workpieces up to 2 tons. A special design of QL-DBH is DBH-12-2, which can blast two workpieces at the same time.
• QL-DBF: This kind of machine comes with a flat-shaped double hanger. It is mainly used to blast flat steel plates and has a lower production cost than QL-DBH.
• A-DBH: This machine has a top-loading design. It is convenient for customers to put workpieces and is usually used in on-site production lines and factories.
• B-DBH: This kind of machine has a front-loading design. Like the top-loading design, it also applies to production lines and factories.
• C-DBH: This double hanger shot blasting machine has a side-loading design. It is usually placed in a workshop to accelerate the production speed of the assembly line.

In addition to these, there are also other double hanger shot blasting machines with special specifications to meet various production needs. If buyers want a certain kind of machine but cannot find it, they can contact the sellers on the platform and ask for the required machine type.

Specifications and Maintenance of Double Hanger Shot Blasting Machines

Specifications:

• Size: These machines come in a variety of sizes, which are determined by the particular industry application. The size affects the weight and dimensions of the components that can be blasted.
• Blast Wheel Number: A double hanger typically has 2 to 4 blast wheels. More blast wheels lead to better blasting coverage and higher processing efficiency.
• Wheel Speed Control: The machine can control the speed of the blast wheels. The controlled speed affects the number of impacts, the processing efficiency, and the surface treatment level of the blasted components.
• Shot Recycling System: Double hangers usually have shot recycling systems to separate the removed contaminants and non-recycled shots. This ensures efficient use of blasting media and maintains machine performance.
• Dust Collection System: This system's specifications can be indicated in terms of the airflow volume and filtration level. A suitable dust collection system helps control environmental pollution and maintain air quality.

Maintenance:

• Regular Inspections: Conduct regular inspections to check for signs of wear, damage, or looseness of key components like the blast wheels, drive motors, and belts. Timely repairs or replacements to ensure equipment reliability and performance.
• Clean Blast Media: Remove contaminated blast media to maintain the quality of the blasting process. This can be accomplished by using the shot recovery system or manually replacing the blasted media.
• Dust Filter Maintenance: Clean or replace the dust filters of the dust collection system based on usage. This can ensure efficient filtration and dust collection, thereby maintaining air quality.
• Lubrication: Regularly lubricate moving parts like bearings and drive chains. This helps reduce abrasion and maintain smooth movement by following the equipment manual and using the proper lubricants.
• Electrical System Check: Periodically inspect the electrical system, including checking the connections and insulation. Ensure the electrical controls and protection devices operate correctly.
