Advantages

Superior Sealing & Environmental Protection

The equipment can be equipped with a rain-proof cover for fully enclosed conveying. This design effectively prevents dust leakage and odor emission, making it highly suitable for operations with strict environmental and hygiene requirements.

Flexible Layout & Multi-Point Operation

It supports single or multi-point feeding and discharging, allowing flexible adaptation to workshop layouts. The segmented flange connection design makes the cover easy to remove, significantly simplifying daily inspection and maintenance.

Customizable Configurations

Available with both shafted and shaftless screw designs. The shafted type is ideal for non-sticky dry powders and small granules, while the shaftless design offers superior anti-wrapping performance, specifically designed for sticky or easily tangled materials like sludge and biomass. Additionally, wear-resistant liners (HDPE or steel) can be installed at the bottom of the trough based on material abrasiveness.

Optional Materials & Bearings

The casing and screw body can be made of carbon steel or stainless steel to meet various anti-corrosion and hygiene standards. Intermediate hanger bearings are available in rolling type (for temperatures ≤80℃) and sliding type (for high-temperature or high-moisture materials) to ensure long-term stable operation.

Application Scope & Precautions

This equipment is extensively used for conveying materials such as flour, cement, fertilizers, coal powder, ash, sand, gravel, and plastic granules. Please note that the U-Type Screw Conveyor is not suitable for conveying easily deteriorated, highly viscous, easily caked, or high-moisture materials. Long-distance conveying and excessive crushing of fragile materials should also be avoided.

Frequently Asked Questions

Q1: What is the difference between a U-Type Screw Conveyor and a Tubular Screw Conveyor? How do I choose?

The U-Type Screw Conveyor features a semi-enclosed U-shaped trough, making it easy to inspect, clean, and maintain. It is ideal for horizontal or small-inclination (≤20°) conveying of powders and small granules. In contrast, the Tubular Screw Conveyor has a fully enclosed circular structure, offering superior sealing for steep inclines or applications requiring strict leak and dust prevention. If your material is highly sticky or prone to wrapping, we recommend the shaftless screw design.

Q2: What is the standard lead time for delivery? Do you support rush orders?

The standard lead time for regular models is typically within 15 working days. Customized non-standard equipment (e.g., special materials or dimensions) generally takes 20-30 working days, depending on the complexity of the process. For urgent projects, we can provide expedited services, with delivery for some smaller equipment in as fast as 15 days.

Q3: How much more expensive is stainless steel compared to carbon steel? Is it worth the investment?

Stainless steel (e.g., 304/316L) typically costs 30%-50% more than carbon steel. However, in industries with strict hygiene requirements (like food and pharmaceuticals) or corrosive environments, stainless steel prevents material contamination and equipment rust, extending the service life by 3-5 times. In the long run, it offers a much higher cost-performance ratio.

Q4: How can material blockage during operation be effectively prevented?

During the selection process, we accurately match the screw diameter, pitch, and speed based on your material characteristics (particle size, moisture, stickiness). For sticky or fibrous materials, a shaftless design or variable-pitch screw is recommended. Additionally, the equipment can be equipped with blockage sensors and variable frequency control to enable automatic reverse-clearing functions.

Q5: What are your after-sales service and warranty policies?

We provide a 1-year warranty for the entire machine (free repair or replacement for non-man-made damaged parts). Meanwhile, we have a professional after-sales support team offering remote technical guidance, video troubleshooting, and on-site installation and commissioning services to ensure the long-term stable operation of your equipment.
