Cement spiral conveyor spare parts introduction

Main spare parts of the cement screw conveyor are screw blade, reducer, intermediate bearing, tailstock, flange plate, universal joint and so on.
Continuouscold rolling of the screw blade makes the surface hardening, so the hardness and wear resistance of the surface is improved, smooth and neatsurface,highoverall accuracy , the smallresistance, and the transmission efficiency is improved as well.

 

 

The universal joint is used to realize the shaft power output of different directions. According to the universal joint, it can be divided into rigid universal joint and flexible universal joint.

 

Advantages of reducer are: new hard tooth surface, high precision, small volume, light weight, strong bearing capacity, high transmission efficiency, convenient installation etc. 

 

The intermediate bearing mainly bears the weight of the shaft, the deformation of the shaft and the radial load generated by the rotation. The intermediate bearing is divided into two kinds:sliding bearing and rolling bearingaccording to the basic structure of the bearing and the friction form of the contact part.

 

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.
