Screw conveyor is continuous conveyor machinery with no flexible traction component. Its working principle is: screw axis rotates in a closed feeding hopper, which makes material not rotate along with the screw because of its own weight and friction with feeding hopper, so can only do lateral movement along the feeding hopper. Some of its type was often used as feeding equipment, measurement equipment, mixing equipment, drying equipment, the kernel and shell separation equipment, unloading equipment and continuous pressure equipment. Screw conveyor is widely used to fishmeal processing industry. Having the following features:
The structure is simple, tight, small size in cross section. Using in other conveying equipment if it is difficult to install or operate.
Reliable working, easy maintenance, low cost, is only a half cost compare with lift machine
Along the entire screw conveyor, the cover can be better sealed, so when in the conveying, the input material can isolate to the outside world, reducing pollution to the environment.
When in the conveying, can put in more feed, also can do more unloading, so it will be flexible to arrange the technology.
In the materials conveying, mixing, tumbling, loosing, heating and cooling etc process operation can be do at the same time.
