High quality screw conveyor

As the essential part of concrete batching plant, the screw conveyor plays a significant role. LS is the screw conveyor code, and L is a spiral, S is horizontal. LS-type screw conveyor diameter is including 100,160,200,250,315,400,500,630,800,1000,1250mm, etc. The single-driver is 35m, which can be at a temperature of -20 ° C to 50 ° C. The material at a temperature of less than 200 ° C is fed in unidirectional at an inclination angle of less than 20 ° C.

1. The advantages of LS-type screw conveyor:

(1) Simple structure, small cross-sectional size, low manufacturing costs.

(2) Facilitates intermediate loading and unloading in a number of locations.

(3) Safe and convenient operation.

(4)Along the entire screw conveyor, and the cover can be better sealed. So in the transport process, the input material and the outside can be isolated.

2. The disadvantages of LS-type screw conveyor:

(1) In the transfer of materials, to overcome the material and the chassis and the friction of the spiral, so the unit power consumption is large.

(2) In the process of moving, due to the role of the screw, the material has a very serious crushing.

(3) Spiral and the shell will wear.

Due to the above advantages and disadvantages, the scope of the use of the screw conveyor in the delivery of various powder, granular and small pieces of materials such as coal, flour, cement, sand, cereals, lumps and stones in the various industries. Because these materials will be wrapped in the spiral, and attached to the rotation without moving forward, or in the bearing at the formation of material accumulation. The screw machine is almost impossible to work.

Spiral machine due to the use of spiral rotation to promote the effective flow of materials cross section is small, it is not appropriate to transport large pieces of material. The screw machine needs a uniform feeding, otherwise it’s easy to cause the accumulation of the machine caused by overload, screw machine crane bearings.
