How to calculate the transmission capacity of the screw conveyor?

1, the density of material and property of the material

2, the selection of the screw conveyor model size and delivery distance, the installation direction, etc..

Approximate calculation formula of screw conveyor:

Capacity Q = 47 D2 N TΦP C（t/h）

Formula:

Q - transport capacity (t/h);

D - conveyor diameter m;

N-- screw shaft speed r/min;

T - pitch m;

Φ - material filling coefficient, under normal circumstances, the grain by =0.25 - 0.4, =0.25 - 0.35 psi oil, wheat bran, rice bran flourψ=0.25, ψ =0.2

P - bulk density  t/m3;

C - conveyor angle coefficient;

S - helical blade pitch (m), S=0.8D of the face, with a blade of S=D.

Calculation formula for ultimate speed:

Formula: N /min - helical axis limit rotational speed (Y);

A - the coefficient of the material properties, the general desirability of grain and oil materials is A=65.

The Main Points for Maintenance the Screw Conveyor

Screw conveyor is bulk material handling equipment, which is widely used in chemical, metallurgy, paper making, and construction industries, etc. What is the main point for maintenance the screw conveyor? Here PK Machinery will show you the answers.

1.The connecting shaft, hanger bearing device and head to the tail bearing should be lubricated before operating.

2.Check the each joint, flange whether cracking and open welding or not and whether the connection bolt are loose broken off.

3. If helical blades have rubbed housing phenomenon, you must check the centerline of wear hanging tile and install whether have the deviation.

4.Check the reamer in the daily operation, shut down for inspection if there are some abnormalities.
