How To Choose A Suitable Screw Conveyor?

First, let's talk about the type of screw conveyor

What types of screw conveyors are there?

Screw conveyors can be classified from three aspects: conveying angle, material, and the central axis.

Type 1: Conveying angle of screw conveyor

1) Horizontal-screw conveyor

It is suitable for horizontal or slightly inclined (below 20º) continuous and uniform conveying of loose materials. It is mainly used for horizontal or small inclined angle conveying of materials.

2) Vertical-screw conveyor

The added material generates friction with the casing under the action of centrifugal force. This friction prevents the material from rotating with the spiral blade and overcomes the gravity of the material falling. From the structural point of view, it conveys materials vertically 90° to the ground, which saves a lot of space and space compared with other screw conveyors. It is suitable for conveying powdery and granular materials with good fluidity. It is mainly used for lifting materials. The lifting height is generally not greater than 8 meters.

Type 2: Material of screw conveyor

1) Stainless steel-screw conveyor

Stainless steel screw conveyors are mostly used in industries or companies that require high sanitary conditions such as food and medicine. The stainless steel material is acid-resistant, corrosion-resistant, and abrasion-resistant. The surface of the spiral pipe diameter is flat without depressions or undulating wavy surfaces, and no distortion. It is also more convenient to clean up after use, and its life span will be longer than that of carbon steel.

2) Carbon steel-screw conveyor

Carbon steel screw conveyor is a commonly used material for screw conveyors, and it is also a screw conveyor that many industries will choose to use. Carbon steel material has low cost, large conveying capacity, good insulation effect, no cooling device, and power consumption Less, but the effect of anti-corrosion and anti-rust will be a little bit worse.

Type 3: Central shaft of screw conveyor

1) Shaft-screw conveyor

The shafted screw conveyor is a central shaft added to the spiral blades. This central shaft can help the conveyor improve efficiency and prevent materials from stacking and slipping. This kind of central shaft design is also the design of most conventional screw conveyors, which is suitable for a variety of loose powder, granular materials that are easy to convey (such as: flour, coal ash, dry mortar, etc.).

2) Shaftless-screw conveyor

Compared with the traditional shafted screw conveyor, the shaftless screw conveyor adopts a design without a central shaft. It uses a flexible integral steel screw to push materials without interference from the central shaft. It has special features for conveying belt-shaped and easy-to-wind materials. Superiority. It is more suitable for conveying materials with high viscosity and easy entanglement (such as: kitchen waste, sludge, etc.).

You can choose horizontal or vertical screw conveyors, stainless steel or carbon steel screw conveyors, shaft or shaftless screw conveyors according to your needs (materials, materials, central shafts, etc.).

In addition, we can also choose the screw conveyor according to the model.

What are the specifications of the screw conveyor?

Screw conveyor is a common type of conveying equipment, there are many models, so let's talk about the common models?

Common specifications and models are GX and LS screw conveyors:

1) GX type screw conveyor is an older screw conveying equipment. There are two types of single pipe and double pipe. It is suitable for horizontal conveying and the inclination angle cannot exceed 20°. It can transport some lumpy (small lumpy materials) such as wheat, corn, soybeans and other grains. Models are: GX200, GX250, GX300, GX400, GX500, GX600

2) LS type screw conveyor is a substitute for GX type screw conveyor. LS type screw conveyor is divided into tube type and U type screw conveyor. At the same time, it is conveyed by LS type screw conveyor on the basis of GX type. The materials are more extensive. Suitable for: material transportation in building materials, electric power, chemical industry, metallurgy, aluminum magnesium, machinery and other industries. The conveying length of LS screw conveyor can reach 70 meters.

Model: LS screw conveyor takes pipe diameter as model: 100mm, 200mm, 250mm, 315mm, 400mm, 500mm, 600mm, etc.

Finally, let's talk about the price of the screw conveyor?

With the increasing demand of the cement market, cement screw conveyors are widely used in concrete mixing plants and dry mortar mixing plants and are very popular. So as a buyer, how should you choose a high-quality and inexpensive screw conveyor? The following suggestions are for reference only when you purchase a screw conveyor.

1. Price trend of screw conveyor

Prices are generally a concern of buyers. On the whole, the price of screw conveyors has not changed much. On the one hand, the requirements for screw conveyors in various industries are getting higher and higher. Conveyor manufacturers improve the quality of equipment through continuous technological updates. , But the overall quotation of the screw conveyor has not changed significantly; on the other hand, with the gradual replacement of traditional raw materials by new energy-efficient and environmentally friendly materials, the screw conveyor’s low energy consumption and environmental protection effect are better, but in view of the national policy With the strong support of the company, the cost of the conveyor equipment produced by the screw conveyor manufacturer has not increased much, so the price of the screw conveyor is not high.

2. Cement screw conveyor price consultation

What is the price of a screw conveyor? Due to different screw conveyor manufacturers, the manpower, material and financial costs invested in the production of screw conveyors are different. Therefore, there is no unified quotation for screw conveyors on the market. How much is a cement screw conveyor requires users Consult the specific conveyor equipment manufacturer. In addition, due to the different types of screw conveyors, the price of screw conveyors is not different. For some users who are not familiar with the selection, you can first explain your own production situation to the screw conveyor manufacturer, and the customer service will help you choose the type. Blind purchase not only increases production costs, but also leads to waste of resources.

There are many types of cement screw conveyors. Different types of screw conveyors may be selected for different production requirements. Our company produces many types and models of screw conveyors. If necessary, please contact us in time.
