What makes a good quality screw conveyor?

Screw conveyor as a very wide range of uses of equipment, can transport bulk materials and small pieces of material, usually according to the shaft and shaftless two kinds of classification. Can also be divided into horizontal and inclined according to the angle of the two, compared to the shaftless screw conveyor is more single, mainly horizontal conveying, the angle should not exceed 20 degrees. Then in the end from what aspects to determine the degree of quality of the screw conveyor? Let’s take a look!
First, to see the thickness of the pipe wall

The so-called spiral conveyor pipe wall, that is, the spiral shell, the thickness is generally more common between 6-8mm. Spiral steel pipe wall thickness of the national standard allowable deviation is between 0.2mm-0.6mm, but individual manufacturers in the production process in order to save costs, the wall down to 3mm, the user may not have obvious abnormalities at the beginning of the use, but in the use of 3 to 6 months, the product will appear to conveyor gradual reduction in the amount of conveying low conveying efficiency and other problems, and in serious cases, will also cause the production line to stop working.
Second, the thickness of the spiral blade

Spiral blade thickness of the country has no clear standards, but the normal are in the wall thickness of about 80%, that is, 5-6mm or so, but also according to the degree of abrasion resistance of the material to thicken. Blade is a fast wearing parts, blade thickness is not enough, will be worn thin, the conveying capacity will be greatly reduced. So the quality of the screw conveyor blade must also be strictly controlled.

Third, bearing

The purpose of refueling the hanging device is to play the role of lubrication, which can effectively avoid the dry grinding of the bearing on the intermediate shaft and the hanging sleeve, and prolong the service life of the hanging sleeve and bearing.
