Screw conveyor

September 14, 2021

Screw conveyor is a commonly used conveying equipment in grease projects, usually used to convey oil. It is a spiral revolving structure, which is driven by a motor to move the material forward to achieve the purpose of conveying. According to the specific plant design, the screw conveyor can transport oil from one point to another horizontally, inclinedly or vertically.

1. Product Type

Screw conveyors are divided into two types: shafted and shaftless. In grease projects, screw conveyors with shafts are generally used. Among them, a special screw conveyor is also used, called a feeder auger. The one-in-two-out type is more used, and is used to transport the oil to two machines for feeding.

2. Working principle

When the screw conveyor works, with the rotation of the screw shaft, the gravity of the oil and the friction generated by the tank wall enable the oil to move forward along the bottom of the conveyor groove under the push of the blades. The oil in the middle is driven by the thrust of the oil behind.

3. Equipment characteristics

(1) The structure of the screw conveyor is relatively simple and the cost is low.

(2) Compact size, small cross-sectional area, and small footprint.

(3) Convenient operation and simple maintenance and management.

(4) Sealed transportation can be realized, which can reduce environmental pollution.

(5) It can convey in the reverse direction, and it can also make a conveyor convey materials in two directions at the same time, that is, away from the center or the collection center.

(6) Convenient loading and unloading. The horizontal screw conveyor can be loaded and unloaded at any point on the conveying line; the vertical screw conveyor can be equipped with a relatively screw-type reclaiming device to have excellent reclaiming performance.

The selection of the size and model of the screw conveyor is generally determined by the overall design of the grease project.
