Small drum shot blasting machine

Types of small drum shot blasting machines

Some types of small drum shot blasting machines include

• Automatic: An automatic small drum shot blasting machine has a blasting cabinet that contains media and components to discharge, contain, and recover blasting media. The machine also has a media reclaim system and separator, a parts-cleaning fixture, and a cyclone that houses the separator. Automatic drum shot-blasting machines work independently of an operator. The Separators are typically designed and operated to be fully automatic, separating media from parts and storing it until needed for further parts cleaning.
• semi-automatic: A semi-automatic machine requires the operator to load parts into the fixture and close the door. After the machine finishes blasting, the operator opens the door and removes the clean parts. The door cannot be opened while the blasting is taking place for safety reasons. A semi-automatic drum shot blasting machine is typically less expensive than an automatic one.
• Containment blast cabinet: The containment cabinet of the machine is built to contain all the blasting media, parts, and blasting equipment in one cabinet. Gun blasting is the most common method of containment blasting, although other methods exist. Parts are manually placed in the cabinet. All gloves, sleeves, and parts entry into the cabinet need to have blast holes and be of adequate size and number to contain the part blast pressure.
• Open face cabinet:An open-face cabinet has an open front, and parts are blasted from the front by pressurized air or water. The operator manually holds the spray gun to cover the part. This is the least safe cabinet, as parts can be ejected from the front of the cabinet and violently BLAM! Open-face cabinets should never be used to blast parts under pressure.
• Drag-down funnel: A drag down funnel is used when the part's configuration does not allow for its entrance into the containment cabinet. The drag funnel is used to direct the blasting media parts into the cabinet. The drag funnel is not safe for open blast cabinets when a separator is not included in the cabinet.
• Walk-in tunnel: A walk-in tunnel is an opening in the top or side of a vertical tunnel cabinet. This is typically done to blast large, flat plate parts too large to fit into the blast cabinet.
• Combination cabinet: A combination cabinet has both the opening and drag-down funnel incorporated into one unit. The combination unit is used when further combination is economically feasible.

Specifications and maintenance of small drum shot blasting machines

Specifications

• Capacity: It typically ranges from 50 to 500 kgs/ batches.
• Working diameter: It can range from 550 mm to 800 mm.
• Working height: It can range from 500 mm to 800 mm.
• Air compressor: It is critical that the correct type and size of air compressor is selected to match the small drum shot blasting machine and the application in order to ensure efficient and effective performance. The air compressor should have a capacity of at least 7.15 l/s (15 cfm) at 100 psi.
• Separator system: This is an important part of the blasting machine as it ensures that the blast media is separated from any other debris or contaminants that may be contained in the compressed air from the air compressor. There are different types of separator systems available, such as cyclones, filters, or trap buckets.
• Dust collector: The dust collector helps to remove and collect any dust that is produced during the blasting process. This is important for environmental and health reasons, as well as to maintain the performance of the blasting machine. A proper dust collector should be implemented in the setup.
• Power: The power of the blasting machine is usually expressed in terms of horsepower (HP) or kilowatts (KW), depending on the motor that drives the blasting wheel. An 8HP/5.5KW motor, for example, can have a blasting capacity of 80 to 100 kgs of iron scrap per hour.

Maintenance

• Weekly: Check the dust collector bag and clean the filter if necessary, check water trap operation, lubricate air motor, inspect blast hose, examine coupling guards.
• Monthly: Clean blast media, dust collector internal inspection, inspect power cords and cables, inspect air compressor for leaks, check drive belts.
• Yearly: Complete preventive maintenance inspection, replace blast wheel components, check sand filter, inspect housing walls, replace dehumidifier.

Scenarios

The small drum shot blasting machines are used for pre-scouring operations in many industries. Welding and metalworking workshops commonly use small drum shot blasting machines. Here are the most common industries and scenarios where the machine is used.

• Small Metal Parts: A small drum machine is well-suited to work on small metal parts. This includes locks, brackets, and fasteners. The surface blasting removes scale and oxidation from these small metal parts. It also got into every nook and cranny for a thorough clean.
• Military and Aerospace: The aerospace and military industries place high importance on the integrity and quality of materials. They use small drum machines to boost the adhesion of crucial components. This includes turbine blades, structural elements, and airframe chassis. Using the blasting machine improves the reliability of parts used in aircraft and military vehicles.
• Medical Equipment: The medical equipment industry also uses the small drum machine. The blasting machine prepares metal surfaces for optimum component fit in medical devices. These devices include surgical instruments, implants, and cathheters. A small machine is suitable for cleaning intricate medical device parts. After blasting, the parts have a smooth surface and are ready for assembly.
• Electronic Devices: The small drum machine can also clean and remove contaminants from housing and electronic device chassis. It works on small parts like circuit boards and connectors. After blasting, the electrical conductive surfaces improve connections and reduce interference.
• Jewelry Making: The small drum machine has historical and modern applications in jewelry-making industries. The machine will remove tarnish from gold, silver, and platinum alloys. It also gets into complex details of jewelry pieces to smoothen surfaces. Jewelry-making artisans get gemstone settings to be more precise and improve overall jewelry quality with the machine.

Q&A

Q1: What are the advantages of a small drum shot blasting machine?

A1: Small drum shot blasting machine have different benefits. They are small, so they fit in tight places. They use less media, saving money. They use less power and water than bigger machines. Many parts load quickly into them. They blast clean many metal parts without costing a lot.

Q2: What is the difference between shot blasting and shot peening?

A2: The main goal is what makes the two processes different. Shot blasting aims to clean and restore the surface of a workpiece. On the other hand, shot peening's goal is to enhance the fatigue life of the workpiece by imparting compressive residual stresses in its outer layer.

Q3: What is the future of shot blasting machines?

A3: The future of all blasting machines, including the small drum type, looks bright. There will be more automatic machines as people want machines that need less work. Smaller, smarter machines will be common. These will have sensors and software to control the blast better. Eco-friendly ways to recycle the blast material will be necessary too. The small machine will meet future cleaning needs economically.

Q4: What maintenance does the small drum shot blast need?

A4: Routine checks and small repairs keep the blasting machine working well. Check the door seals to make sure air does not leak. Door seals need to be looked at and fixed if they are worn. Look at the media separator and the dust filter. If they are blocked, clean them. If the hose connections are loose, tighten them. Dust collection works better when filters are clean and not worn out. Look over the blast wheel for wear or loose parts. Typical wear parts like the blast wheel blades should be checked often. If they are worn, replace them. A small amount of preventive maintenance keeps larger repairs and breakdowns away.
