Sand Blasting Machine Supplier in India

Surface International is a leading manufacturer of sand blasting machines in India. Surface offers a wide range of sand blasting machines, including portable sand blasting machines, sand blasting cabinets, vacuum type shot blasting machines, and airless shot blasting machines.

Working Process of a Sand Blasting Machine

Sand blasting machines are commonly used for rust removal, paint removal, surface cleaning, and surface preparation. These machines utilize abrasive media such as garnet, glass beads, steel shot, or steel grit. The specific abrasive media used may vary depending on the application and the required surface finish.

Sand blasting machines can generally be classified into air-operated and airless systems. Air-operated sand blasting machines use compressed air to propel the abrasive material onto the surface, whereas airless shot blasting machines use a blast wheel to propel the abrasive material against the components.

General Working Process

First, the components are placed inside a blasting chamber or in a suitable open blasting area. Next, the sand blasting machine is loaded with the appropriate abrasive media. The blasting process then begins according to the machine type, with the abrasive being propelled against the components.

After blasting, the abrasive may be recovered and recycled, while the dust collection system collects dust and fine particles generated during the process.

Shot Blasting Machine Manufacturing Process

A sand blasting machine is constructed by integrating several systems, including a blasting chamber, dust collection system, abrasive handling system, and media recovery system.

The blasting chamber is designed according to the specific component and application requirements. It may be constructed using MS (Mild Steel) or SS (Stainless Steel) sheets, depending on the type of machine and application.

SS cabinets are commonly used for wet blasting applications. The cost of the machine can vary significantly depending on the material, thickness, size, and construction of the blasting chamber.

A dust collection system is used to collect dust and fine particles generated during blasting. Different types of dust collectors are available, including fabric bag dust collectors, reverse pulse-jet dust collectors, and cyclone-type dust collectors.

How a Dust Collection System Works

Fabric Bag Dust Collector – In this system, dust is collected using filter bags. The accumulated dust can be removed through manual shaking or mechanical, motor-driven shaking, depending on the design of the dust collector.

Reverse Pulse Jet Dust Collector – In this system, the dust collection process is automated. Filter bags or cartridges trap the dust, while compressed-air pulses periodically clean the filters and remove the accumulated dust.

Cyclone-Type Dust Collector – This type of dust collector uses centrifugal force to separate and collect dust particles from the air stream.

Media Recovery System

The media recovery system depends on the type and design of the blasting machine. Airless shot blasting machines may utilize components such as a screw conveyor, bucket elevator, and rotary screen for abrasive recovery and separation.

Air-operated sand blasting machines may use a reclaimer to separate reusable abrasive media from dust and contaminants, allowing the abrasive to be reused during the blasting process.

Sand Blasting Machine Spare Parts

A sand blasting machine consists of several important components and spare parts, such as nozzles, which are used to direct abrasive material onto the components.

A pinch valve is used to control and regulate the abrasive flow. A moisture separator removes moisture from the compressed air, while a control valve regulates the flow of abrasive material.

A remote control system can be used to automatically start or shut off the air and abrasive supply during operation, improving operator safety and process control.

Sand Blasting Machine Price

The price of a sandblasting machine depends on its model and configuration. For instance, the cost of a portable sandblasting machine differs from that of a sandblasting cabinet or an automatic shot blasting machine.

Prices can range from ₹50,000 to ₹1,00,00,000 or more, depending on the machine type, capacity, automation level, spare parts, dust collector, chamber size, and other technical requirements.

Standard models may have fixed prices, while customized machines can have different prices depending on the required specifications. For example, a portable sandblasting machine may cost around ₹70,000, while adding accessories such as a wet head tool may increase the overall cost depending on the configuration.
