Screw Conveyor

Product Details:

Introduction:

Flexible screw conveyors, also known as auger conveyors, are a type of mechanical conveying system used to move bulk materials horizontally or at an incline. They are widely used in various industries such as food processing, agriculture, pharmaceuticals, chemicals, and plastics manufacturing. These conveyors are popular due to their versatility, cost-effectiveness, and ability to handle a wide range of materials, including powders, granules, pellets, etc.

Information:

Design: Flexible screw conveyors typically consist of three main components: a flexible or semi-flexible tube, a rotating helical screw (auger), and a drive mechanism. The tube is usually made of rubber, PVC, or polyurethane, while the screw is made of metal or durable polymer materials. The drive mechanism, often an electric motor, powers the rotation of the screw.

Versatility: Flexible screw conveyors can be designed to suit various applications and space constraints. They can be straight, curved, or inclined, allowing for flexible routing within processing plants or facilities. Additionally, they can be easily integrated with other equipment such as feeders, hoppers, and bins.

Material Handling: These conveyors are capable of handling a wide range of materials, including powders, grains, saw dust, wood chips, cement, or any dry material.

Low Maintenance: Flexible screw conveyors require minimal maintenance compared to other types of conveying systems. The absence of complex moving parts reduces the likelihood of mechanical failures, and the flexible tube can be easily removed for cleaning or replacement.

Cost-Effectiveness: These conveyors are often more cost-effective than alternative conveying systems, especially for short to medium distances and lower capacity requirements. They offer a simple and efficient solution for bulk material handling needs.

Working Principle:

A flexible screw conveyor operates on a straightforward principle: it uses a helical screw enclosed in a flexible or semi-flexible tube to move materials from one point to another. Here's a breakdown of its working principle:

Material Loading: The material to be conveyed is loaded into the inlet of the flexible screw conveyor. This could be done manually, or by using feeders or other equipment depending on the specific application.

Screw Rotation: Inside the flexible tube, there's a rotating screw or auger. This screw is typically made of metal or a durable polymer. When the motor is activated, it rotates the screw within the tube.

Material Conveyance: As the screw rotates, it effectively pushes the material along the length of the tube. The helical shape of the screw creates a continuous flow path for the material, preventing backflow and ensuring smooth conveyance.

Tube Flexibility: The tube enclosing the screw is usually made of a flexible material such as rubber or PVC. This flexibility allows the conveyor to bend and curve around obstacles or to reach different points within the processing or storage area.

Discharge: At the discharge end of the conveyor, the material exits the tube. Depending on the application, there may be additional equipment such as valves or chutes to control the flow of material at the discharge point.

Control: The speed of the screw rotation can be adjusted to control the rate of material flow through the conveyor. This allows for precise control over the feeding or conveying process.

Cleaning and Maintenance: Flexible screw conveyors are relatively easy to clean and maintain. The flexible tube can be easily removed for cleaning or replacement, and the screw can be accessed for inspection or maintenance as needed.
