Screw Conveyor

A screw conveyor is a material handling device that is among the most popular devices found in both the shot blasting and the manufacturing industries. It is a mechanical system that employs a rotating helical screw blade (also known as flighting) to move a solid, dry, or even powdery bulk material either horizontally, at an incline, or even vertically. Shot blasting industries make use of screw conveyors to transport abrasives like steel shots, steel grit, garnet, aluminum oxide, and copper slag from one part of the machine to another, which is, in most cases, going from the blasting chamber to the bucket elevator or storage hopper.

At Shot Blaster, our screw conveyors are specially made with heavy-duty construction, wear-resistant materials, and precision engineering to cater to brutal abrasive materials while still performing efficiently and effectively. Among airless shot blasting machines, blast rooms, roller conveyor machines, or hanger-type shot blasting machines, the screw conveyor is the one that facilitates easy media recovery and circulation; albeit, it is the main injection system of blasting installations that ensures continuous operations.

Working of Screw Conveyor

Screw conveyor's working principle is based on the rotation of the helical screw blade inside a trough or a tubular casing. As the screw turns, it moves the abrasive or bulk material ahead by the friction force between the material and the rotating flights. This movement enables the abrasives to be collected, transported, and discharged at the desired point.

Basically, in the case of a shot blasting machine, the screw conveyor gathers the abrasives falling into the blasting chamber and transports them to the bucket elevator. There, the abrasives are lifted, cleaned, and returned to the blasting cycle. The closed-loop system allows the use of steel shots, grit, garnet, and aluminum oxide to the maximum extent, as a result of which the wastage is reduced and the efficiency is improved.

Additionally, screw conveyors are heavily used in cement plants, steel industries, mining, chemical processing, and food industries to carry powders, granules, and bulk materials apart from the blasting systems. Their efficient yet simple working mechanism makes them one of the most versatile and cost-efficient conveying solutions.

Applications of Screw Conveyor

The screw conveyor finds application in diverse industries. Some of the typical usages are:

• Airless Shot Blasting Machines: Abrasives are transported to elevators and separators via the screw conveyor.
• Blast Room Systems: As a result of the efficient abrasive recovery and reuse, the system provides.
• Tumble Blast & Hanger Type Machine: The devices return the abrasives to the recovery system.
• Roller Conveyor Shot Blasting Machine: They are designed to keep a continuous abrasive flow.
• Sand Blasting Machine: The sand or any other abrasive material is moved without any jerk or stoppage.
• Industrial Applications: The screw conveyor is used for bulk material handling in the cement, fertilizer, chemical, food, and steel industries.
• Mining Industry: The ores, minerals, and bulk raw materials are carried by the screw conveyor.

Advantages of the Screw Conveyor

When a screw conveyor is used in blasting and industrial applications, it essentially delivers the following benefits to the users:

• Efficient Abrasive Handling: The operation allows a smooth, uninterrupted transport of the medium.
• Versatility: The equipment is capable of managing a variety of abrasive materials, as well as the rest of the industrial materials.
• Space Saving: The compact design allows the user to save horizontal or inclined installation space.
• Integration Friendly: The conveyor can be easily installed together with the bucket elevator, gearbox, and geared motor without any issues.
• Customizable Design: Diameter, length, and even material can be changed to suit the customer's needs.
• Durability: The product is constructed with heavy-duty and wear-resistant materials, thus suitable for the abrasive industries.
• Cost-Effective: The machine helps in reducing manual labor work and thus assures the efficient recovery of the media in the blasting system.

Screw Conveyor Price

As a leading manufacturer and supplier, we offer an affordable screw conveyor price in India with superior quality. For a screw conveyor, prices vary depending on the size, the material, the capacity, and the level of customization, among other things. Normally, a compact screw conveyor in a tumble blast machine will be more affordable than a heavy-duty conveyor in an industrial blast room or roller conveyor blasting machine. Shot Blaster is proud to offer the most competitive prices on excellent quality screw conveyors that will last a long time and are easy to maintain. Our range is suitable for shot blasting, sand blasting, or industrial bulk handling, and we deliver the best value for the money with various customization options to fit your specific needs.
