Grain Screw Conveyors

Introduction of Grain Screw Conveyors

Grain Screw Conveyors is a screw conveyor used for horizontal, inclined or vertical conveying of various bulk grains in the grain industry. The whole machine is preferably made of 304 stainless steel, which is not easy to rust and meets the hygienic requirements of the grain industry. The diameter is 100mm-1250mm, and the conveying length It can reach 70 meters, and the conveying capacity can reach 458 cubic meters per hour.

Different Types of Grain Screw Conveyors for Sale

As a direct selling manufacturer of spiral conveyors, we provide different types of grain spiral conveyors:

Grain spiral conveyors: Traditional grain spiral conveyors are usually composed of hard spiral blades and pipes, suitable for linear conveying of granular materials such as grains, and are widely used in grain processing, warehousing, food processing and other industries for conveying grains, feed and other materials.

Hose grain spiral conveyor: Compared with traditional hard tube spiral conveyors, it uses soft pipes and is suitable for occasions where grains need to be conveyed in different directions and heights, such as agricultural fields, food processing industries, etc.

Grain Screw Conveyors Features

Body material: selected 304 stainless steel material, anti-corrosion, anti-rust, in line with food production hygiene standards.

Large conveying capacity: all kinds of powder and granular grain conveying, the output can reach 458 cubic meters per hour.

Conveying distance: The conveying length of a single machine can reach 30m, and the segmented installation can reach 100m.

Sealing structure: The fully enclosed and easy-to-clean spiral surface can ensure that the food will not be polluted or leaked.

How do Grain Screw Conveyors work?

When Grain Screw Conveyors work, they rely on the rotating helical blades to push and transport the grain. The force that makes the grain rotate with the helical blades is the weight of the grain itself and the frictional resistance of the screw conveyor casing to the material. The movement of the grain in the middle bearing depends on the thrust of the grain moving forward in the back. Therefore, the transportation of grain in the screw conveyor is completely a sliding movement.

Grain Screw Conveyors Structure

The grain screw conveyor is composed of multiple components, each of which has a specific function and works together to complete the material conveying task. The following are the main components of the grain screw conveyor:

Screw body (screw shaft): The screw body is the core part of the grain screw conveyor, which is composed of a screw shaft and is responsible for rotating and conveying the material along the screw shaft.

Feed port: The feed port is the starting point for material loading, and the grain or granular material to be conveyed is loaded into the conveyor.

Discharge port: The discharge port is the outlet of the material. After the material is conveyed, the grain or granular material leaves the conveyor through the discharge port.

Bearing support: The bearing support plays the role of supporting and fixing the screw shaft to ensure the stable rotation of the screw shaft.

Transmission device: The transmission device provides power through a motor or other power source to drive the screw shaft to rotate and push the material for conveying.

Casing (pipeline): The casing or pipeline is the outer shell of the screw conveyor, which wraps the screw shaft to prevent material from spilling or splashing.
