Introduction to Cement Screw Conveyor

► Brief Introduction
Cement screw conveyor is bulk material handling equipment, which usually consists of a tube containing either a spiral blade coiled around a shaft (sometimes called an auger), driven at one end and held at the other. The main parts include tube, shaft with spiral blades, inlet and outlet chutes, as well as driving device.

► Working principle
Within a tube, the LSY screw conveyor uses a rotating helical screw blade, to move granular and powdery materials. Cement screw feeder is usually installed at a incline in many industries, such as concrete mixing station, bulk material transit storage, etc.

► Main Features
1.Simple structure, good sealing, easy operation and low power invest cost.
2.It has the features of small screw diameter, high rotation speed and large capacity, specially suitable for inclined transport. The angle is up to 60 degree.
3.Widely used in chemical, metallurgy, paper making, and construction industries, etc.
4.Axle head and conveying spiral adopt spline connection, with features of convenient mounting&disassembling, large load capacity and stability.
5.All sections of screw conveyor are connected with flange. Also screw blades are integral connection.
6.Inlet and outlet chutes have many kinds of connections, such as flange, sack, universal joint, etc.

► Selection condition
Primary considerations for the selection of a screw conveyor are as follow:    1.Type and condition of the materials to be handled, including maximum particle size, and, if available, the specific bulk density of the material to be conveyed.

2.Quantity of transported material, expressed in pounds or tons per hour.

3.The distance for which the material is to be conveyed.

Below is the necessary information for the selection of a screw conveyor system, presented in a series of five steps. These steps are arranged in logical order, and are divided into separate sections for simplicity. The five steps are:    1.Establishing the characteristics of the material to be conveyed.

2.Locating conveyor capacity (conveyor size and speed) on capacity tables.

3.Selection of conveyor components.

4.Calculation of required horsepower.

5.Checking of components torque capacities (including selection of shaft types and sizes)
