In the ceramsite production process, the transportation of raw materials is an important part of the production process. Due to the high moisture content of the ceramsite raw materials, traditional transportation equipment has certain limitations in material adaptability and on-site location layout. Henan Zhengzhou Mining Machinery Co., Ltd will introduce a conveying equipment suitable for ceramsite raw materials-shaftless screw conveyor. Because of its non-central shaft structure, the steel spiral body is directly connected with the transmission device, and can be made into a cantilever structure, which is especially suitable for feeding materials from the kiln tail of the ceramsite rotary kiln.

1. Product Introduction:

Shaftless screw conveyor is an alternative product of shaft conveyor. Its screw body is a shaftless screw. It has the advantages of high work efficiency, simple maintenance, less pollution, and low noise. Not only can it transport light, soft, small, and ribbon-shaped floating substances that cannot be transported by old-fashioned equipment, but it can also separate sand and water and squeeze dirt. Beautiful appearance and reasonable structure.

2. Working principle:

The working principle is the same as the shaft screw conveyor, and the material is pushed forward by the rotation of the blade. The performance characteristics of the shaftless screw conveyor are: Compared with the traditional shaft screw conveyor, the shaftless screw conveyor has the above outstanding advantages due to the design of no central shaft and the use of a flexible integral steel screw to push materials. , Good environmental performance. Compared with the shaft screw conveyor, the weight and cost will be reduced a lot.

3. Product Performance Characteristics:

Shaftless screw conveyors can convey materials that traditional shaft screw conveyors and belt conveyors cannot or are difficult to convey, such as granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, easy to wind and easy to block Materials, materials with special hygiene requirements.

1) Good environmental performance. The fully enclosed and easy-to-clean spiral surface can ensure that the conveyed materials are not polluted and will not leak the conveyed materials.

2) The conveying capacity is large, and the conveying capacity is 1.5 times that of the screw conveyor with the same diameter.

3) The torque is large, the energy consumption is low, and the discharge port is not blocked.

4) The conveying distance is long, and the conveying length of a single machine can reach 60~70m.

5) Compact structure, space saving, beautiful appearance, easy operation, economical and durable.

4. Structure of Shaftless Screw Conveyor:

Shaftless screw conveyor is mainly composed of driving device, head assembly, casing, shaftless spiral body, tank liner, inlet, outlet, cover (when needed), base, etc.

Drive device: adopt cycloid pin wheel reducer or shaft-mounted hard-tooth surface gear reducer. When designing, the drive device should be located at the end of the discharge port as much as possible, so that the spiral body is in a state of tension during operation.

The head is equipped with a thrust bearing, which can bear the axial force generated when conveying materials.

Case: The case is U-shaped or O-shaped, with a rain-proof cover on the upper part, made of stainless steel, carbon steel or glass steel.

Shaftless spiral body: The material is stainless steel or carbon steel.

Tank lining board: The material is wear-resistant plastic board or rubber board or cast stone board.

Inlet and outlet: There are two kinds of square and round. Generally, the form of inlet and outlet is determined by the user.
