What is fixed drum and what is its use?
The fixed drum or (drum head) is one of the conveyor drums that is designed and produced in two types, complex and simple. In the conveyor belt, there is a belt that is connected to the two ends of the drum from the end and the beginning. Basically, the first drum is called the stimulus and the second drum is called the moving one, which we will read about later. The drive drum is a type of roller that is connected to the gearbox. This device has many applications, most of which are in the group of industrial activities. The fixed drum or head drum, also known as (driving drum), is one of the parts in the conveyor belt. The coating of this structure is usually made of rubber, which increases the life of the belt. The drumhead is connected to the gearbox and the electric motor, and actually receives its rotational power from them. Another task of this drum is to create friction between the belt and its body surface, with this the belt is stretched and does not shift. The drum head also affects the tension of the belt, and its surface should not be uneven because it may damage the belt. Belt tension is also adjusted by adjusting the drum angle.
As mentioned earlier, the fixed drum is located at the beginning of the conveyor. The material of this structure is ST37 steel. Therefore, it also determines the direction of the belt movement, and prevents the belt from deviating from its original path. The diameter of the fixed drum depends on the type of load and the capacity of the conveyor belt. In relation to the application of fixed drum, we can also refer to cases such as plaster, cement and lime industries, steel, coal, sand and agricultural activities.
Checking the details of the fixed drum application
The application of fixed drum is different based on its structural type. The fixed roller drum, also known as the head drum or driving drum, is located at the beginning of the conveyor belt and performs important functions in the operation of the conveyor belt. One of the main uses of static drums is to create movement. In the following, we mention some of the most important functions of a drum.
Adjusting the belt tension and guiding the belt: By adjusting the angle of the drum head, the belt tension can be adjusted. Proper belt tension prevents premature wear and tear. The drum head determines the direction of the belt by being placed at the beginning of the conveyor belt. This prevents the belt from deflecting and coming out of the way.
Changing the direction of the belt and increasing the life of the belt: if we place the drum head at the right angle, we can also change the direction of the belt. In addition to changing the direction, the life of the part is also determined by the drum head, in fact, by stretching and adjusting the tension of the belt, it prevents premature wear and tear.
Reduction of friction and tension of the belt: in the fixed drum, by using suitable covers such as rubber, the existing friction between the drum head and the belt can be reduced and help the belt to move more easily and smoothly. Choosing a fixed roller drum according to its variety in the market, choosing the right type requires expertise and experience. The drum head puts the belt under tension by creating friction between it and its surface. This tension prevents this structure from sliding and moving the load on it.
Fixed drum application applications
Contrary to expectations, a drum has many uses, some of which we described in the above material. Unaware that the word industry has more categories than you think. So the effectiveness of this structure does not end in this section. Based on the research, a drum can be useful in processes such as material transfer, component separation, drilling and cutting, and setting the speed and direction of movement.
Material transfer
An important application of the fixed drum is material transfer, this structure is used in the conveyor belt to transfer various devices. By placing the material on the conveyor and moving it, the material is continuously transferred from one point to another. This application is used in various industries such as mining industry, construction industry and food industry.
Material separation
In the inner part of the fixed drum of the conveyor belt, different materials can be separated. By adjusting the speed and angle of the conveyor belt, materials of any weight can be separated from each other. This application can be used in industries such as mining, beverages, and recycling.
Drilling and cutting material
Another application of the fixed drum in the conveyor belt is drilling and cutting materials. By placing the appropriate tools on the conveyor and adjusting the speed and power of the drum, the material can be punched or cut. This application is useful in industries such as wood and metal. Of course, these items must have a high volume.
Setting the speed and direction of movement
Another case is the use of a fixed drum, adjusting the speed and direction of movement of the drum in the conveyor belt. It is used to adjust the speed and direction of material movement. With these changes in the drum, the speed and direction of movement of the material can be adjusted. Among the applications of fixed drums in
this case are industries such as the packaging industry and the automotive industry.
The difference between a fixed drum and a moving drum
Fixed roller drum and movable drum are both conveyor components that perform similar functions, but the application of fixed drum and movable drum are different from each other. Of course, they also differ in the way they move and control the belt tension. For your better understanding, we will describe each one below.
how to move
As mentioned, the fixed roller drum or drum head is connected to the electric motor and gearbox and rotates directly and takes its power from them. But the movable roller drum moves freely and receives its displacement force from the conveyor belt.
belt tension
In the fixed roller drum (drum head), the angle of the drum is used to adjust the tension of the conveyor belt, in this case the belt tension is precisely adjusted. But in the moving roller drum, this problem is automatically adjusted by the weight of the drum. This is why the tension of this part is more accurate in the fixed drum.
Application of fixed and moving drum
Drum head is actually used for conveyors that have high capacity and high speed. But the moving roller drum is suitable for conveyors that have less capacity and also low speed. It should be noted that the fixed drum is more complicated than the moving drum.

final word
A stationary drum is actually a part that helps to complete a structure such as a conveyor belt. This drum is connected to the engine and gearbox and gets its traction force in this way. Creating friction between the body and the belt is one of the important tasks of this structure. This product has many applications, including coal industries, agricultural activities, steel, sand, etc.
