Deflection drum, idler drum and drive drum

So that Material is picked up and transported in the best possible way the drum coating of the surface plays a crucial role.

Drive rollers, deflection rollers and idler pulleys can painted, galvanized or with sheet rubber or Baytec coated .

Paint is usually used as drum coating to protect / prevent against moisture or corrosion Paint is cheaper than other drum coatings, but often has lower friction properties and is therefore less suitable for systems with high loads.

Galvanized Drum coating is used for Increased corrosion resistance of the conveyor drums and thus offer a longer service life. However, galvanized conveyor belt drums are more expensive and have a smooth surface which can make grip difficult.

Sheet rubber and Baytec coatings are particularly popular with a conveyor drum, as they provide high abrasion resistance have and a long lifetime of the deflection pulleys, drive pulleys and idler pulleys. Rubber drum coating can be applied to create a additional friction between the conveyor belt drum and the conveyor belt. This will Increases adhesion and prevents material slippagewhat the Operational safety and Efficiency the system improved.

Drum coating, especially plate rubber coatings, can smooth or diamond-shaped The choice of coating depends on various factors, such as the material being conveyed, the speed of the conveyor belt, and the application conditions.

Smooth drum coatings are generally better suited for Use at higher belt speeds, she reduce friction and enable one improved gliding ability of the material being conveyed, which is particularly advantageous for materials such as sand or gravel. Furthermore, smooth coatings are easier to clean and offer less space for dirt and deposits to accumulate on and in the conveyor drums.

Diamond-patterned drum coatings However, they prove to be particularly at lower belt speeds or steeper conveyor belt systems extremely advantageous. Due to profiled vertical and horizontal lines as well as a higher friction, which helps to better pick up and hold the material being conveyed. This ensures that the Material neither slips nor falls off, which increases operational reliability. However, diamond-patterned coatings can be more difficult to clean and may require additional maintenance of the conveyor belt drive pulley or deflection pulley.

Overall, choosing the right surface coating for a conveyor belt pulley is crucial for a safe, efficient, and cost-effective conveyor system.

Over time, due to wear and tear or other influences Problems arise, such as Deformation or irregularities in concentricity the conveyor belt drum. This can lead to reduced performance and even to Damage to the conveyor system .

Therefore, a Over-rotation of the conveyor belt drum necessary, so that Geometry and functionality restored and the System performance assured is.

The Over-rotation a deflection drum, idler drum and drive drum is a special procedure, which contributes to optimal concentricity. Basically, there are two types the overturn: cylindrical and crowned (conical):

• While at the cylindrical overturn the drum surface is removed parallel to the drum diameter, thus creating a precise cylindrical shape…
• … will be at the crowned over-rotation Material is specifically removed from the drum surface to create a spherical or conical shape.

The conveyor drums should generally be overturned from a wall thickness of 5 mmin order to achieve better concentricity and thus improve the smooth running of the system.

It is crucial to mention that not every conveyor drum is suitable for over-rotation is the Diameter and wall thickness are decisive factors in determining whether a conveyor belt drum can be over-rotated or not.

Conveyor belt drive pulleys with a thin wall thickness often cannot be over-twisted, as this can result in the wall thickness falling below the recommended minimum. Therefore, it is essential to carefully inspect the conveyor belt pulley and, if necessary, consult a drive pulley manufacturer such as FMG to ensure that the over-twist meets the necessary requirements and that the conveyor belt drive pulley maintains optimal geometry and correct concentricity.

To ensure that the drive pulley, deflection pulley, or idler pulley is manufactured in optimal condition, overwinding should always be performed by experienced professionals. Improper overwinding can lead to uneven concentricity, irregular wear, and other problems related to the overwinding process. Rely on experts like the knowledgeable staff at FMG Förderelemente Mecklenburg GmbHto get a professional assessment and implementation of the over-rotation sure.

Professional overwinding can help extend the service life of your conveyor belt drive pulleys and idler pulleys. By eliminating unevenness and deformation on the conveyor pulley, wear is reduced and further wear of the pulley surface is slowed. Additionally, optimal overwinding can lead to increased conveyor capacity by improving concentricity, which in turn leads to higher system performance.

We always use the latest technology to ensure that your conveyor pulleys precisely machined and function optimally. Contact us and we will create a transparent and non-binding cost estimate.

Various Drum diameter enable better adaptation of the conveying speed to the needs of the system. Due to the physical laws of the conveyor belt drive drum, a change in the drum diameter is directly transferred to the conveyor speed. Thus, a faster rotation of the drum leads to a higher conveyor belt speed. A larger diameter provides additional support for these effects.

Increasing the speed of the conveyor belt in turn enables higher throughput of materials. This means that larger quantities of material can be transported from A to B in a shorter time. Measurably increases productivity.

A larger diameter the drive drum offers numerous Advantages, especially in situations where a faster and more effective material conveying A higher belt speed can reduce the Increase production capacity and thus the Rentabilität of companies. In addition, the increased conveyor speed can help to avoid bottlenecks in material processing and enable faster Transport of large quantities of material to allow.

However, when deciding on a change in drum diameter, all relevant factors be taken into account to ensure that the change is actually necessary and implemented sensibly. A thorough review of the aspects, including the System requirements, the type of material, the capacity and the Costs, is of great importance to achieve the best possible results.

However, there are also factors that can impair the positive effect of a larger drive pulley diameter on conveyor speed. One of these is the performance of the system. Before commissioning larger drive pulleys, as well as deflection pulleys and idler pulleys, you should ensure that your system is capable of achieving higher speeds. Inadequate power supply or instability of the conveyor system can lead to difficulties in increasing conveyor speed, which can result in a loss of performance.

Another important factor is the type of material being conveyed. Depending on the type and composition of the material, the drum thickness can also play a decisive role. Thicker or heavier material increases the load on the conveyor belt drive drum, so a thicker or stronger drum may be necessary. In such cases, it is important to conduct a thorough analysis of the materials and the performance characteristics of the system to ensure that a change in the drum diameter is actually necessary.

Our experts at FMG will be happy to assist you in reviewing the adjustment needs of your drive and idler pulleys by Comprehensive assessment of the requirements of your conveyor system In addition to the technical and operational requirements, safety factors, operational key figures and possible economic effects in the assessment.

As part of the analysis, the conveyor pulleys themselves are also examined to determine what changes are necessary. If a change in the pulley diameter is proposed, we offer recommendations for selecting the optimal size and thickness of the drive pulley or deflector pulley. Factors such as the type of material and the impact on transport speed and capacity play a crucial role here. A thorough and expert analysis of the pulley dimensions and performance parameters provides an optimal basis for informed decisions. Potential impacts on equipment lifespan, maintenance, and repair costs can also be considered.

It is also important to note that changing the drum diameter may not always be the best solution. There are often other factors that affect conveyor speed, such as machine power control. In some cases, minor adjustments, such as over-spinning the drum surface or adjusting the drive settings, may be enough to achieve the desired conveyor speed.
