Have you ever wondered how the goods are easily sent from one place to another on the conveyor belt? An important part behind this is the Troughing Idler. Today we will talk about this.
What is an idler?
First of all, let us know what an idler is. In simple words, an idler is a small roller that is installed under the conveyor belt. These rollers help the belt to rotate and help in moving the goods from one place to another.
What is the function of Troughing Idler?
Troughing idlers are a special type of conveyor belt idler. Which is a major component in conveyor systems used in industries like mining, power plants and manufacturing. Its job is to keep the belt slightly pressed in the middle, so that the goods moving on the belt remain in a channel. This is necessary so that the goods do not fall off the belt.
Angle angle of troughing idler
The angle angle of troughing idler indicates the angle at which the troughing idler presses the belt.
The value of this angle usually ranges between 20 and 45 degrees. However, this exact value depends on several factors, such as:
- Width of the conveyor belt
- Type and quantity of material moving on the belt
- Speed ​​of the conveyor
- Length of the conveyor
- Coefficient of friction of the material
For maximum efficiency and proper flow of material, selection of the correct angle code is crucial. If the angle code is too low, the material may spill and fall on the belt. On the other hand, if the angle code is too high, it may exert excessive pressure on the belt and impede the flow of material.
Therefore, while selecting a troughing idler, it is necessary to take these factors into consideration and it is advisable to seek advice from an engineer or expert.
Troughing Carrying Idler (3 rollers)
It is supporting the conveyor’s upper belt.
Flat Carrying Idler (1 roller)
A flat carrying idler is like a small wheel on a conveyor belt. It helps the belt move smoothly by supporting its weight. This wheel has only one part that rolls, making it simple but effective in keeping the belt running without any trouble.
V-type Carrying Idler (2 rollers)
A V-type carrying idler is like a pair of small wheels shaped like a V on a conveyor belt. These wheels help the belt carry heavy things by supporting it from both sides. The V-shape helps keep the belt centered and prevents it from moving sideways, making sure things travel smoothly on the conveyor.
Detailed Conveyor Idler Features (Roller Idlers)
Description: These are the most common type of conveyor idler and are used to support the conveyor belt and its load. They consist of a steel tube, shaft, bearings, and seals.
Key Features:
- Diameter: 50mm – 219mm (2″ – 8 5/8″) – This range caters to various conveyor belt widths and load capacities.
- Length: 190mm – 3400mm (7.5″ – 13.4 ft) – Allows for customization based on conveyor system requirements.
- Applications: Steel industry, harbor, coal industry, power industry, cement industry, etc. – Suitable for a wide range of industries handling bulk materials.
- Tube Material: Q235 – A high-strength, low-alloy steel commonly used in conveyor idlers due to its durability and cost-effectiveness.
- Shaft Material: 45# Steel – A medium carbon steel known for its strength and good wear resistance, ideal for supporting the roller and bearing assembly.
- Bearings: Single & Double Row Deep Groove Ball Bearing 2RZ&2Z with C3 clearance – These bearings offer smooth operation, high load capacity, and C3 clearance provides better performance at higher operating temperatures.
- Seals: Grease retaining inner seal with Multi-stage Labyrinth and Retention Cap with Outboard Rubbing Flinger Seal – This multi-layered sealing system protects the bearings from dust, dirt, and moisture, extending lifespan.
- Lubrication: Lithium soap type grease with Rust Inhibitors – This type of grease offers good lubrication performance and rust protection, extending the life of the idler.
- Welding: Mixed gas shielded arc welding end – This welding method provides a strong and clean weld for a secure connection between the tube and shaft.
- Painting: Multiple options are available:
- Ordinary Painting – Affordable choice for applications with minimal environmental exposure.
- Hot Galvanized Painting – Provides excellent corrosion resistance for harsh environments.
- Electric Static Spraying Painting – Creates a smooth, even finish with good durability.
- Baked Painting – High-quality finish with excellent adhesion and weather resistance.
- Customization: The manufacturer can produce idlers according to specific customer requirements, allowing for adaptation to unique applications.
Additional Considerations:
- Capacity: The load capacity of the idler depends on factors like roller diameter, bearing type, and spacing between rollers.
- Speed: Idlers are designed for specific conveyor belt speeds to ensure proper operation and minimize wear.
- Material Handling: The choice of roller material and coating might be influenced by the type of material being conveyed (e.g., abrasive materials).
**By understanding these features, you can select the right roller idler for your specific conveyor system needs.
