Product Description

Product Parameters

There are several different types of pulleys used in conveyor belt systems, each with its own function to keep the system running smoothly.

Drive Pulleys (Head Pulleys)

• Driving the belt: In systems where the drive unit is in the head section, the belt conveyor head pulley is powered and is used as the driving pulley that turns the entire belt.
• Redirecting the belt: Conveyor head pulleys change the direction of the belt, typically 180 degrees, so the belt can return for another cycle.
• Providing tension: Drive pulleys are typically adjustable, allowing for tension to be placed on the conveyor belt. Proper belt tension is required to prevent slippage.
• Tracking the belt: A key role of belt conveyor drive pulleys is to keep the belt centered. Proper alignment prevents the belt from drifting or running off-track

Snub Pulleys

• Belt Traction: Snub pulleys are used to increase the wrap angle (belt wrap) around the driving pulley, improving belt traction and reducing belt tension. By reducing tension your belted conveyor system can be better optimized for less wear and tear.
• Belt Tracking: Snubbing pulleys can also be used to keep the conveyor belt centered and reduce belt wandering.

Idler Pulleys ( Return Pulley or Return Roller)

• Belt Support: A conveyor idler pulley may also be called a return roller and is used to provide support for the conveyor belt. When positioned at intervals along the conveyor belt, return pulleys will prevent the belt from sagging which could cause misalignment or damage.
• Reducing Friction: By providing additional rolling surface area for the belt, idlers reduce the friction between the conveyor belt and the structure. This also reduces the power needed from drive pulleys to move the belt providing smoother overall operation of the equipment.

Bend pulleys

• Changing Direction: The main function of a conveyor bend pulley is changing the direction of the belt. These pulleys are typically used to make a 180-degree bend in the tail section of the conveyor belt near the take-up.
• Bend pulleys can be designed to accommodate different belt types such as flat, cleated or modular plastic belts helping to provide smooth belt travel around curves.

Tail Pulleys

• Belt Redirection: A conveyor tail pulley provides transition from the carrying run (moving materials) to the return run (belt traveling back to head pulley), usually through a 180-degree belt change in direction
• Belt Tension: Conveyor tail pulleys work together with the take-up section to maintain the correct amount of tension on the conveyor belt. Typically, a tail pulley can be adjusted to increase or decrease tension as needed.
• Belt Tracking: Similar to drive pulleys, tail pulleys help keep the conveyor belt aligned and properly centered to avoid misalignment and premature wear.

Take-up pulleys

• Belt Tensioning: The most important function of a take-up pulley is to apply or adjust tension on a conveyor belt. Having the correct amount of tension on the conveyor belt is required for efficient operation and prevents belt slip, sagging and premature wear.
• Taking-up Belt Stretch: Due to load tensions and prolonged usage, conveyor belts can stretch over their useful lifetime. Take-up pulleys can be adjusted to take up the stretch, preventing belts from becoming too loose.
• Accommodating Belt Installation / Removal: Conveyor take-up pulleys can be adjusted to create slack in the belt allowing for easier removal and installation of new conveyor belts during maintenance.

Conveyor belt systems rely on various types of pulleys to operate efficiently. Each pulley type plays a critical role in ensuring proper operation of the conveyor system while used in material handling systems.

	Drive/Head Pulley - A conveyor pulley used for the purpose of driving a conveyor belt. Typically mounted in external bearings and driven by an external drive source.
	Return/Tail Pulley - A conveyor pulley used for the purpose of redirecting a conveyor belt back to the drive pulley. Tail pulleys can utilize internal bearings or can be mounted in external bearings and are typically located at the end of the conveyor bed. Tail pulleys commonly serve the purpose of a Take-Up pulley on conveyors of shorter lengths.
	Snub Pulley - A conveyor pulley used to increase belt wrap around a drive pulley, typically for the purpose of improving traction.
	Take-Up Pulley - A conveyor pulley used to remove slack and provide tension to a conveyor belt. Take-Up pulleys are more common to conveyors of longer lengths.
	Bend Pulley - A conveyor pulley used to redirect the belt and provide belt tension where bends occur in the conveyor system.

TD75 rubber casting pulley:

1. Conveyor parameter matching:
   1. Bandwidth adaptation: The diameter and length of the TD75 drum need to match the bandwidth of the conveyor. Generally, the wider the bandwidth, the larger the diameter of the drum should be correspondingly to ensure effective support and driving of the conveyor belt. For example, for a narrower small conveyor, a smaller diameter drum may meet the requirements; while for a large conveyor with a large conveying capacity, a larger diameter drum is needed to ensure the stable operation of the conveyor belt.
   2. Conveyor speed adaptation: Select an appropriate drum according to the designed conveyor speed. If the conveyor speed is high, the drum needs to have sufficient strength and precision to withstand the centrifugal force and friction caused by high-speed operation. At the same time, in the case of high-speed operation, the dynamic balance requirement of the drum is also higher; otherwise, vibration will occur and affect the normal operation of the conveyor.
2. Drum type selection:
   1. Drive drum: If the drum is needed to provide power to drive the conveyor belt, a drive drum should be selected. The drive drum is usually connected to a driving device such as a motor and a reducer, and transmits power to the conveyor belt through friction. When selecting a drive drum, consider its load-carrying capacity, torque transmission capacity, and connection method with the driving device.
   2. Deflection drum: The deflection drum is mainly used to change the running direction of the conveyor belt. According to the layout of the conveyor and the change of the conveying direction, reasonably select the number and position of the deflection drums. Generally, the diameter of the deflection drum is slightly smaller than that of the drive drum, but it also needs to be selected according to the specific conveying requirements.
3. Drum structure and material:
   1. Structural design:
      1. Cylinder structure: The cylinder structure of the TD75 drum has two types: steel plate welding structure and cast-welded structure. The manufacturing process of the steel plate welding structure drum is relatively simple and the cost is low, which is suitable for general conveying occasions; the cast-welded structure drum has higher strength and better integrity, and can withstand greater loads and impacts, which is suitable for heavy-duty conveying or applications in harsh working conditions.
      2. Shaft design: The shaft of the drum is a key component and needs to withstand large bending moments and torques. The material of the shaft is generally medium carbon steel or alloy steel, which is subjected to processes such as quenching and tempering to improve its mechanical properties and wear resistance. At the same time, there are also multiple installation methods for the shaft, such as integral bearing seats and split bearing seats, which need to be selected according to actual installation and maintenance requirements.
   2. Material selection:
      1. Cylinder skin material: Common cylinder skin materials include carbon steel, stainless steel, etc. The drum made of carbon steel material has a low cost and high strength, but it is easy to rust in some corrosive environments; the drum made of stainless steel material has good corrosion resistance and is suitable for industries with high requirements for hygiene and corrosion resistance such as food and chemical industries, but the price is relatively high.
      2. Rubber coating material: If it is necessary to coat the drum with rubber to increase friction, prevent the conveyor belt from slipping or reduce wear, rubber coating materials such as natural rubber, nitrile rubber, neoprene rubber, ethylene propylene diene monomer rubber, polyurethane, etc. can be selected. Different rubber coating materials have different performance characteristics such as wear resistance, oil resistance, and aging resistance, and need to be selected according to the specific use environment and characteristics of the conveyed material.
4. Load-carrying capacity requirements: Determine the load-carrying capacity of the drum according to factors such as the weight, volume, and density of the conveyed material. If the conveyed material is heavy or large in volume, a drum with strong load-carrying capacity needs to be selected to ensure its long-term stable operation. At the same time, consider the static load and dynamic load capacity of the drum and the change in load-carrying capacity under different working conditions.
5. Manufacturing process and quality:
   1. Manufacturing process: High-quality TD75 drums should adopt advanced manufacturing processes such as precise welding processes, strict control of machining accuracy, and perfect heat treatment processes. These processes can ensure the structural strength, dimensional accuracy and surface quality of the drum, thereby improving the service life and reliability of the drum.
   2. Quality inspection: Choose a manufacturer with quality assurance to ensure that the drum has undergone strict quality inspections such as static balance inspection, dynamic balance inspection, and weld flaw detection. These inspections can detect possible defects and problems in the manufacturing process of the drum and ensure the quality and safety of the product.
6. Convenience of installation and maintenance:
   1. Installation method: Consider whether the installation method of the drum is simple and convenient, and whether it can be quickly and accurately installed with the conveyor frame. Some drums may adopt special installation structures or connection methods, which need to be fully considered when selecting to ensure the smooth progress of the installation process.
   2. Maintenance requirements: Select a drum that is easy to maintain, such as a drum that is easy to disassemble and replace parts such as bearings and rubber coatings. This can reduce maintenance costs and maintenance time and improve the operating efficiency of the conveyor.
