Vertical screw conveyer is a continuous conveyer equipment ，it uses feeding serew to convey materials,it is suitable for Powder, massive, granular materials, such as flour, grains, cement, chemical fertilizer, ash, sand, gravel, coal, coal, etc. It is suitable for building, metallurgy, chemical industry, mining, machinery manufacturing, coal ash, tobacco, food, medicine and other industries.

The working principle and application scope

Vertical screw conveyer is suitable to transport powder, granular, inviscid drying materials that density ≤1.3t/m3 in vertical or large slope Angle. Such as grain, oil bran, feed, chemical raw materials, cement, etc. The temperature of material does not generally exceed 80 ° C. it is not suitable to convey the materials that perishable, viscous and easy to agglomerate.

selection calculation
1、
We can caculate according to the empirical formula: Q=8.007·D·3n （m3/n）Q means delivery value（m3/n）D means screw diameter （m）,n means Spiral Speed （r/min ）.

2、
We can caculate motor power according to the empirical formula：N=0.015258856Q·r·H （Kw），N means motor power（Kw ），Q means delivery value m3/n），r means volume-weight（t/m3）,H means the distance between feed port and discharge port （m ）.

3、
combination length: The height of Vertical screw conveyer is the distance from feed port and discharging port,the range is from 2.5 meters to 15 meters,o.5 is a grade,the customers choose it according to requirements.

 
4、
Vertical screw conveyer  usually adopts  driving device, the motor is installed on head of the machine,
power transmission is from belt to spindle,so it can drive the screw.

200 and 250 type is Single drive, Maximum motor power is 15Kw, 315 type is Single drive and dual drive.
The motor power is equal to or less than 15 kw,we can choose Single drive; the motor power is more than 15Kw,we choose the dual drive. The users should be responsible for the its own design.
