Shaftless, tubular, U-shaped shafted screw conveyors - Jiahe

Product Analysis Report of Jiahe Conveying Equipment Technology Co., Ltd. (Focus: Shaftless Screw Conveyor, Tubular Screw Conveyor, U-Shaped Screw Conveyor)

I. Introduction

Jiahe Conveying Equipment Technology Co., Ltd. (hereinafter referred to as "Jiahe") possesses extensive experience in the field of material conveying and offers a comprehensive range of screw conveyor products, including shaftless screw conveyors, tubular screw conveyors, and U-shaped screw conveyors. Different types of screw conveyors are suitable for different materials and application scenarios. This report aims to provide a detailed analysis of the differences between these three types of screw conveyors, their respective industry applications, technical parameters, application scenarios, and precautions, to provide professional guidance for customers in selecting the appropriate equipment.

II. Analysis of Screw Conveyor Types

1. Shaftless Screw Conveyor

• Structural Characteristics: A shaftless screw conveyor eliminates the traditional spiral shaft; the spiral blades are directly welded to the conveying tube, forming an integral whole. This design allows it to convey materials with larger diameters and allows for slight changes in conveying direction.

• Advantages: Strong conveying capacity, wide adaptability, can convey large-diameter materials, simple structure, and easy maintenance.

• Disadvantages: Relatively short conveying distance, higher requirements for the uniformity of the material.

2. Tubular Screw Conveyor

• Structural Characteristics: A tubular screw conveyor utilizes a traditional spiral shaft and spiral blades, with the spiral blades welded to the spiral shaft. The conveying tube is sealed, preventing material leakage and suitable for powdery, granular, or slurry materials.

• Advantages: Long conveying distance, good sealing performance, prevents material leakage, and high conveying efficiency.

• Disadvantages: Relatively small conveying capacity and higher requirements for the particle size of the material.

3. U-Shaped Screw Conveyor

• Structural Characteristics: A U-shaped screw conveyor is a special type of tubular screw conveyor, with the conveying tube shaped like a "U," and the spiral shaft located at the bottom of the U-shaped tube. This design allows for better control of the conveying direction and prevents material from tipping during the conveying process.

• Advantages: Controllable conveying direction, prevents material tipping, and high conveying efficiency.

• Disadvantages: Relatively complex structure and higher cost.

• Typical Parameters: Conveying capacity: 20-80 t/h, Conveying distance: 20-80 m.

• Precautions: Ensure the conveying tube is clean to prevent food contamination.

• Typical Parameters: Conveying capacity: 15-60 t/h, Conveying distance: 30-100 m.

• Precautions: Select corrosion-resistant materials to prevent chemical materials from corroding the equipment.

• Typical Parameters: Conveying capacity: 5-20 t/h, Conveying distance: 10-40 m.

• Precautions: Strictly control the temperature and humidity during the conveying process to prevent deterioration of medicinal materials.

• Application Scenarios:

3. U-Shaped Screw Conveyor

• Cement Plant: Used to transfer cement from the grinding machine to the storage silo.

• Power Plant: Used to transfer ash from the ash remover to the ash yard.

• Port: Used to transfer coal, ore, and other materials from the ship's hold to the pier.

• Typical Parameters: Conveying capacity: 100-300 t/h, Conveying distance: 50-150 m.

• Precautions: Ensure the slope of the conveying tube is appropriate to prevent cement accumulation.

• Typical Parameters: Conveying capacity: 80-200 t/h, Conveying distance: 30-80 m.

• Precautions: Ash often contains corrosive substances; select corrosion-resistant materials.

• Typical Parameters: Conveying capacity: 150-400 t/h, Conveying distance: 100-200 m.

• Precautions: Pay attention to moisture prevention to prevent equipment corrosion.
