General overview

The conveying equipment are designed for different transport request. diversity conveyor forms can be chosen like belt conveyor, spiral conveyor, shaftless flexible screw conveyor and pneumatic conveyor. they are widely used in the transportation and other industries.

Description

Screw conveyor is a kind of machinery that is to achieve the purpose of conveying by motor driven screw rotation. It can convey materials by horizontal, inclined or vertical direction. Its advantages like simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, convenient closed transportation and so on. The screw conveyor can be divided into shaft screw conveyor and shaft free screw conveyor in the form of transmission, and also be divided into U-shaped screw conveyor and pipe screw conveyor in shape.

Features and Applications

Screw conveyor has the following characteristics

1) The structure is relatively simple and the cost is low.

2) Reliable operation and simple maintenance and management.

3) Compact size, small section size and small floor area.

4) It can realize sealed transportation.

5) Easy loading and unloading. The horizontal screw conveyor can load and unload at any point on its conveying line; The vertical screw conveyor equipped with relative screw reclaiming device can have excellent reclaiming performance.

6) It can be transported in reverse, or one conveyor can transport materials in two directions at the same time, that is, to the center or away from the center.

7) The unit energy consumption is large.

8) Materials are easy to grind and wear during transportation, and spiral blades and material grooves are also seriously worn.

structure characteristics

1) There are three types of spiral blades of screw conveyor: solid spiral surface type, belt spiral surface type and blade spiral surface type. Solid spiral surface is called s-making method, and its spiral pitch GX type is 0.8 times of blade diameter. LS type spiral conveyor is suitable for conveying powdery and granular materials. The belt spiral surface, also known as d-system method, has the same spiral pitch and spiral blade diameter. It is suitable for conveying powdery and small materials.

2) The spiral blade of screw conveyor has two rotation directions: left rotation and right rotation.

3) The types of screw conveyor include horizontal fixed screw conveyor and vertical screw conveyor. Horizontal fixed screw conveyor is the most commonly used type. The vertical screw conveyor is used to lift materials in a short distance. The conveying height is generally no more than 8m. The spiral blade is of solid surface type. It must have horizontal spiral feeding to ensure the necessary feeding pressure.

4) At the material outlet end of LS and GX screw conveyors, 1 / 2 ~ 1 circle of reverse spiral plate shall be set to prevent powder from blocking the end.

5) The screw conveyor is composed of screw machine body, material inlet and outlet and driving device.
