Conveyor belt mechanism is a system that minimizes manpower in the transfer of products from one place to another. Conveyor conveyor belts are very important transfer vehicles used to transport materials over long distances horizontally or inclined and on moving belts.

If tons of material is to be transferred from one area to another in a short time, the use of belt conveyor transport system is inevitable. Conveyor belt systems are used in many areas from the industry sector to airports, as well as processes such as transporting materials from one place to another, unloading, storing or taking them from the warehouse.

For this reason, today in mines, iron - steel factories, thermal power plants, ore, coal, lime, sinter etc. The main conveyor system in the transfer of materials is belt conveyors. With these conveyors, it is possible to transport both dry and wet materials, as well as small granular materials such as ash, flour, sand, and granular materials such as agricultural products. It is also possible to transport multi-part materials such as coal or stone.

Where an inclined transport system requires it, the slope should not exceed 20 degrees. Normal conveyor belt systems operate at temperatures between -20 and 125 degrees. However, by using specially developed tapes, the tape withstand temperature can be increased up to 170 degrees. The transport distance of the conveyors is from one meter to 1000m. Band widths can be from 300mm to 3000mm. It is also possible to transport to longer distances. However, this requires special solutions. Today, there are specially designed belt systems with a length of about 100 km.

Conveyor belt systems operating using two rotating drums can consist of many hooks, gears, buckets and rubber belts depending on the desired length.

Conveyor belt systems are produced as mobile or fixed according to the needs of the enterprises. The mobile conveyor belt system is mounted on a wheeled chassis and can be easily transported to the desired location. In addition, they have an adjustable mechanism according to the ground slope of the place where they will be installed.

History of Conveyor Belts:

Conveyor belt systems from their first emergence to being usable for today's multi-purpose is basically related to the belt material used in the belt system becoming higher quality.

It is seen that belt conveyors emerged with the industrial revolution in the 1830s. It has been widely used in the world, especially after the improvement of tape quality and the use of triple rolls. Today, when compared to trucks, it is seen that the cost of transporting materials with conveyor belt systems is ten times cheaper than transporting by truck.

The material of conveyor belts can be fabric, rubber, leather, metal or thermoplastic. On the other hand, the belt dimensions and weight that the belt can weigh are very important.

Advantages of Conveyor Belt Systems:

Conveyor conveyor belt systems; They are unrivaled transport mechanisms with their low cost, ease of use, wide range of use. Benefits of conveyor conveyor belts:

- High amount of material transport,

- Less energy consumption,

- Low investment and maintenance cost,

- Ease of use,

- Labor saving and high efficiency

As a result;

Conveyor belts require a higher upfront investment compared to trucks, but are also more economical in the long run. This is because trucks and buckets have a relatively shorter economic life compared to conveyor systems, thanks to regular maintenance and spare parts supply.

Conveyor Handling Systems, truck etc. It is more economical and efficient than the transport vehicle fleet for the following reasons:

1. It can be laid up to the desired location on the entire working area. Because mines and quarries often have harsh conditions that restrict the safe movement of vehicles.

2. Conveyor belts are more environmentally friendly than trucks that consume fossil fuels. They also emit less noise and dust pollution compared to trucks.

3. Conveyor belt transport systems trucks etc. It is more economical and efficient compared to transportation vehicles. Maintenance, labor and operating costs are lower.

4. Conveyor belt systems are safer

5. The conveyor belt is in continuous operation and much less number of workers are required during operation, which prevents work accidents to a large extent.

Structure of Conveyor Belt System

These conveying systems basically consist of a belt equipped with rollers, which is constantly in motion between two drums.

Major Elements of Conveyor Belt Systems:

-Conveyor belt


-Drive drum,

-Tail drum,


-Loading bunker,

-Dump shot,

-Tension equipment,

-Scraper assembly,

Conveyor Belt

An ideal conveyor belt should have the following features:

-Withstand high tension and weight,

-Do not stretch too much,

- Moisture-proof feature,

-Resistance to the winding movement of the drums,

- Resistance to abrasive material and long life,

-In special cases, resistance to extreme heat, cold, climatic factors, oil, oxidation, ozone, etc.


Rolls have two functions:

1- To facilitate the rotation of the band,

2-To shape the tape into a groove if necessary.

The rolls on which the material is carried are called "carrier rolls", and the reels that carry only the empty tape at the bottom are called "return rolls".


In belt conveyors, the elements that move the belt are rollers and drums. Two types of drums are used in conveyor belt systems as drive and tail drums. The drum that provides the movement of the band with the rotational movement it receives from the motor and thus the transfer of the material is called the "drive drum". Tail drums are used to adjust the tension of the belt.


All the equipment of the conveyor is placed on a chassis.

loading hopper

The material must be loaded properly and proportionally on the belt conveyors. Thus, empty or overloaded areas will not be formed on the belt, and there will be no loss of capacity and spillage of the material outside the belt.

unloading bunker

The material carried on the belt must be transferred from the belt to another area at the discharge site. For this, an unloading bunker is used.

Cleaning scheme

If the material carried on the belt is wet and sticky, this material will not separate from the belt and will damage the drum, rollers and operating equipment on the return path. For this reason, during the transportation of the material that clings to this type of belt, a sheet metal plate should be laid at the bottom of the carrier rolls to prevent the material spilled from the band edges from falling into the return path.



During the production process, a significant amount of dust is released during the crushing, screening, transport, drying, mixing and loading processes that must be done in asphalt plants. Outdoor aggregate storage areas, conveyor belts and aggregate transfer points can also be a source of high amounts of dust due to wind effect in open areas.

In dryers where the aggregate is heated, undesirable gases such as sulfur dioxide, carbon monoxide and nitrogen oxides originating from combustion, along with dust, and harmful organic substances that may arise by heating the bitumen material are also formed.

Depending on the fuel type, dust and gaseous pollutants originating from combustion are formed from the hot oil boilers used while heating the bituminous material.

Dust will be released as a result of crushing-sieving processes in integrated facilities where aggregate production is also carried out. In other words, drilling, blasting operations, loading-unloading, crushing-sieving operations in the quarry and open transport and storage of materials are also sources of dust emission.


The main pollutant for both integrated asphalt plants and non-integrated plants is dust. Dust emission can be reduced by collecting dust with dust collection systems and passing it through a dust filtering system. The most preferred filtration system is bag filters. Apart from this, electrostatic filters and aqueous dust control systems can also be used.

Apart from this, dust emissions that will occur on the aggregate conveyor belts can be reduced by using closed belt systems. The dust retained in the dust filtering system is reused as filler material in production and provides an economic contribution.

In order to reduce gas emission, drying and heating processes in dryer rotary kilns should be done with quality fuels and combustion systems. The heat energy of the waste gases must be recovered and used in the drying system. Dust emissions that will occur in these furnaces should also be filtered with the existing dust collection system or an independent dust control system should be established.

In mixers where aggregate, bitumen and other additives are mixed, it is recommended to collect and treat the organic compounds that evaporate during loading on the truck and during the bitumen filling.

Organic harmful substances will be formed as a result of heating the bituminous material in drum mix (continuous mix) asphalt plant dryers and facilities using recycled asphalt. Depending on the amount of oscillations, control techniques can be applied.

In addition, in-plant roads should be covered, cleaned and dust suppression applied in order to reduce dust emission in production areas. In addition, windbreak curtains and dust suppression systems should be used in storage areas. Thin materials should be stored indoors as much as possible.

It is recommended to carry out crushing-screening activities in completely closed areas in order to reduce dust emission and to be easily controlled.

Electrical energy may be preferred as an option for heating insulated bitumen tanks.



Asphalt (bitumen); It is obtained by precipitation of crude oil in nature in natural processes or by human distillation. This substance has a hydrocarbon composition and a color ranging from dark brown to black. Sometimes bitumen is modified with polymers to improve performance.

Asphalt, which is used as a superstructure material especially in road construction works; It is an adhesive bituminous binder mixture produced by including minerals and aggregates. Aggregates in asphalt mixtures to be used in asphalt road construction are hard minerals selected according to the characteristics of the superstructure to be produced. These are materials such as crushed stone, gravel and sand.

The most produced asphalt road types are divided into three as hot mix asphalt, cold asphalt and surface coating.

1-Hot mix asphalt: Aggregate at 145-160°C and bitumen liquefied by heating at almost the same temperature are mixed at the desired rates. Aggregate and bitumen ratios in the mixture vary according to the characteristics of the product to be produced. However, almost 95 % of the mixture is aggregate and 5 % is bitumen.

In hot mix asphalt production facilities, aggregates in 3 different sizes are generally used. The aggregates are dried in a dryer at a temperature of 145-160°C and then mixed with the bitumen heated at 155-160°C in a mixer. Additives such as fillers and stone mastic can also be added to the mixture. Each batch mixing time is approximately 45 seconds. Bitumen and aggregate must be completely homogenized with each other. Fine mineral fillers are also added to the mix and help bind the bitumen onto the aggregate. Asphalt production facilities produce asphalt at approximately 160°C. Two types of asphalt plants are used, fixed and mobile.

2-Cold asphalt: It is a mixture created with fine aggregate, asphalt emulsion, mineral fillers and water. It is used in the maintenance and repair of the asphalt pavement surface. Its cost is lower than hot asphalt and other coating applications.

Cold asphalt is very effective in eliminating ruts, bumps and potholes on the road that affect driving performance for those who drive in traffic, and in cases where surface smoothness is aimed. It is also economical and easier to manufacture.

The bitumen mixture is generally applied to the road surface with the paving machines mounted on the truck and designed accordingly. Additional additives can be added to the mixture mortar if desired.

3-Surface coating: It is the application where the binder and aggregate are laid on the surface one after the other. With the asphalt distributor, asphalt emulsions are sprayed on the road surface, then gravel is laid on top of it and the material is compacted with a roller. Surface coating can also be applied as one or more layers. It is easy to lay and the cost is low. However, since it is affected by changing climatic conditions, maintenance and repair costs are high.

Asphalt Production

The shorter the distance from the asphalt production facilities to the work area, the faster the production can be made and the completion of the work.

There are three types of asphalt plants, namely Batch plants, Drum mix (continuous mixing) plants and Integrated asphalt plants. All three types can be produced as fixed and mobile.

1-Batch Type Asphalt Plent: It is the most used facilities in the world. High quality production can be made in this type of plant. After all components are individually weighed according to the desired specifications in a production process, they are included in the production process and each production period is completed in approximately 40-50 seconds. The production amount in such plants is lower than drum mix plants.

2-Drum mix (continuous mix) asphalt plant: In this type of facilities, unlike batch plants, bitumen and other additives are added to the aggregate when leaving the dryer. Since there is no mixer, waiting times (mixing, opening and closing the mixer cover, material discharge, etc.) do not occur as in batch type plants. Therefore, production amounts are higher than batch type plants.

3-Integrated asphalt plant: They are compact plants with crushing-screening systems on them. While aggregates that are crushed and separated according to their size are used in classical facilities, the crushing-screening process is carried out on an asphalt plant in compact facilities.

Modules in Asphalt Plant and Asphalt Production Stages

asphalt plants; It consists of feeding silos, conveyor belts, dryer, automatic scale, mixer and loader modules.

Feeding silos: These are silos where aggregate is stored.

Conveyor Belts: It is the system that enables the aggregate stored in the silos to be transported to the dryer called a rotary kiln.

Dryer: It is a rotary kiln where the material coming from the feeding band is dried. Material enters from one end of the rotary kiln, and there is a burner at the other end. The burners heat and dry the aggregate in the rotary kiln to a predetermined temperature.

Sieve and hot aggregate hopper: The hot aggregate coming from the dryer is separated according to their size in the sieves and comes to the hot aggregate hopper. The material on the sieve is sent back to the crusher. The materials coming to the hot aggregate bunkers are taken to the mixer in the desired amount with the automatic weighing system according to the production recipe.

Mixer: It is the part where the aggregates coming from the hot aggregate bunkers and the hot bitumen material meet and are mixed. The hot mixture coming out of the mixer, which combines the aggregate and the binding bitumen in a homogenized manner, is transferred directly to the trucks or silos.

Dust control system: There is a dust control system in all asphalt plants since there will be a high amount of dust emission during the operations in the asphalt plants. Generally, a dry type, replaceable bag filter system is used.

Bitumen system: It consists of bitumen storage tanks and a heating system. Bituminous materials brought to the plant from the refinery by heat-insulated vehicles are stored in bitumen tanks. There is a heating system in the tanks to prevent the bituminous material from freezing. Generally, liquid or gas fueled hot oil boilers are used.
