China Conveyor Trough-Type Idler Rollers Manufacturer, Manufacturers

The conveyor drum is a key component in the conveyor system, used to support and guide the conveyor belt or chain, ensuring the smooth movement of materials during the conveying process. According to different driving methods, conveyor rollers can be divided into powered roller conveyors and unpowered roller conveyors.

The power drum conveyor drives the drum to rotate through an electric motor, thereby driving the conveyor belt or chain to move. It is suitable for situations that require high conveying speed and large load-bearing capacity. Its advantages include high conveying efficiency, stable operation, and strong adaptability.

Non powered drum conveyors rely on the weight of the material itself or external thrust to drive the drum to rotate, making them suitable for conveying lightweight materials or situations that require energy savings. Its advantages include simple structure, easy maintenance, and low cost.

Product Description

Introduction to Drum

Conveyor drum is a cylindrical conveying accessory, divided into driving drum (transmission drum) and driven drum. These rollers play a crucial role in various mechanical equipment, including circular screen printing machines, digital printers, conveying equipment, papermaking and packaging machinery, etc.
Rollers are usually made of seamless steel pipes, but other materials such as aluminum alloy 6061T5, 304L/316L stainless steel, 2205 duplex stainless steel, cast steel parts, or solid forged alloy steel cores can also be used according to different process requirements. The selection of these materials depends on the specific application environment and performance requirements.

Key Selection Points

The key points for selecting conveyor rollers mainly include the following aspects:
  • Frame Material Selection: Common rack materials include carbon steel, aluminum profiles, and stainless steel. For the food industry, it is recommended to prioritize choosing a fully stainless steel body to ensure hygiene and corrosion resistance.
  • Drum Material Configuration: Optional materials include carbon steel galvanized, chrome plated, nickel plated, cast adhesive (encapsulated), stainless steel, and steel plastic steel, depending on specific working environments and material characteristics.
  • Surface Treatment: Carbon steel body can be treated with spraying, plastic spraying, or baking paint. Stainless steel body can be treated with mirror polishing, matte, sandblasting, or wire drawing to meet aesthetic and protective requirements.
  • Load Capacity: The material and model of the drum should be determined primarily based on the load capacity to ensure stability and safety during conveyor operation.
  • Food Industry Standard: In addition to choosing a fully stainless steel body, stainless steel rollers should be prioritized to further ensure food safety and equipment cleanliness.
  • Height & Safeguard Configuration: Normally, the top height of the drum is slightly lower than the side height of the machine body. Special settings can raise the side height or add side shields, edges, or guardrails.
  • Requirement Details: Users should provide detailed information including material name, properties, packaging size, machine material, approximate size, speed, and conveying capacity when inquiring.

Frequently Asked Questions

Q1: What are the main applications of conveyor drums?
Conveyor drums are crucial accessories used in mechanical equipment such as circular screen printing machines, digital printers, conveying equipment, and papermaking or packaging machinery.
Q2: What materials can be used to make conveyor rollers?
While seamless steel pipes are standard, other options include aluminum alloy 6061T5, 304L/316L stainless steel, 2205 duplex stainless steel, cast steel parts, or solid forged alloy steel cores, depending on process needs.
Q3: Which frame and roller materials are best for the food industry?
For food-grade environments, it is highly recommended to select a fully stainless steel body frame and prioritize stainless steel rollers to guarantee optimal hygiene, cleanliness, and corrosion resistance.
Q4: What surface treatments are available for conveyor drums?
Carbon steel bodies can undergo spraying, plastic spraying, or baking paint. Stainless steel bodies can be mirror polished, matte, sandblasted, or wire drawn.
Q5: Can the side height of the conveyor frame be adjusted relative to the drum?
Yes. While the top height of the drum is normally slightly lower than the frame side, the sides can be customized to be higher or at equal height, and accessories like side shields or guardrails can be added.
Q6: What details should be provided to get the most suitable conveyor drum solution?
You should provide specific requirements including material name, material properties, packaging size, machine material, approximate overall size, speed, and conveying capacity.
