Screw Conveyors

1. screw conveyor – The basics

Screw conveyor is a device widely used in the industry to transport solid materials in the direction of torsion and in horizontal, vertical, and inclined directions. It consists of three main parts: screw chute, screw shaft and screw blade.

– Screw trough: there are 2 types of U-shaped trough and round screw trough, made of steel plate with a common thickness of 2 -10 (mm) or heat-resistant steel plate if the material temperature is high, steel must be used.

– Screw: is made from steel pipe to ensure the standards of thickness and hardness, the end of each pipe segment is welded with a flange to install an intermediate bearing.

– Impeller: made from steel plate, or stainless steel welded to the screw to form a spiral blade.

2. Working principle

The operating principle of the screw conveyor is based on the combination of the gravity of the material and the frictional force between the material and the machine wall. As the screw rotates, the blade generates thrust, pushing the material to move reciprocally along the bottom of the conveyor.

The material at the mid-axis point is pushed by the material from behind, while the non-rotating nut moves in the direction of the screw. The screw propels the material and ensures uniform distribution over the entire conveyor.

3. Application of screw conveyor

Screw conveyor has many applications in different industries. Here are some common applications of screw conveyors:

Wastewater treatment: With the ability to effectively transport sludge. Sludge conveyor screws are widely used in wastewater treatment systems to transport sludge in the best way.

Food industry: In the food industry, equipment is used to transport wastes and scraps, making production and handling processes more efficient.

Agriculture: In the agricultural industry, equipment also plays an important role in handling organic fertilizers and other organic materials. It helps to transport and distribute fertilizers evenly across the gardens, ensuring an efficient supply of nutrients to the plants.

Construction industry: In the handling and transportation of construction materials such as sand, stone, cement, and screw conveyor has an important role. It helps to ensure a smooth production and construction process, reducing labor time and effort.

4. Benefits of screw conveyor

High efficiency: With a simple design structure and effective operating principle, the screw conveyor allows the conveying and handling of materials quickly and efficiently.

High reliability: Sludge conveyors are usually made from high-quality materials such as sheet steel and stainless steel, ensuring durability and rigidity during use.

Cost savings: Using a screw conveyor can help save production and operating costs. With efficient material handling and distribution, it reduces labor time and effort, as well as saves materials and energy.

Flexibility: Can be customized and tailored to suit the specific requirements of each application. This makes it suitable for many different industries and sizes.
