MACHCON® Belt Conveyor
One of the most important means of transport is the belt conveyors which are used for the transportation of solid materials in a continuous manner to the long distances horizontally or within certain limits.
With these conveyors, it is possible to transport dry or wet materials as well as multi-part materials such as granular, coal or stone materials, such as pulverized agricultural products such as ash, flour and sand.
Fields of Use
Belt conveyorsare used in many areas such as loading, discharge, stocking and reclaiming. Commonly in coal and mine quarries; ore preparation and enrichment plants; stone crushing, screening and washing facilities; sand and mold grinding works in foundries; ports in mine ore, coal, grain etc. loading and unloading of materials; paper, sugar industry and grain silos are mainly used in belt conveyors.
Properties of Transported Materials
The materials conveyed on the belt conveyors are divided into two parts as piece and bulk materials. Part material can be counted individually, crate, sack, box, carton and so on. materials. The masonry materials are in the form of multi-part, granular and powdery materials. It is of great importance to know the physical properties of the materials especially during the transportation of bulk materials.
Conveyor Structure and Features
The belt conveyors consist essentially of a moving endless belt stretched between the two drums and supported by pulleys.
- Conveyor Belt Systems
- Steel chassis,
- Driving drum,
- Pulley groups,
- Stretching assembly
- Distortion drum,
- Loading vessel,
- Discharge vessel,
- Cleaning layout,,
- The pit where the debris is collected.
The material that conveys the material is resistant to the pulling force from the drums and the weight, temperature and wear effects of the material.
For a fault-free operation, a conveyor belt is expected to have the following characteristics:
- Less moisture absorption,
- High strength,
- Low specific gravity,
- Low lengthening,
- Resistance to bending effects caused by hugging and grooving in drums,
- Resistance to alternative stresses,
- Resistance to abrasive effect of material and long life,
- Special conditions; temperature, cold, climate effects, oil, oxidation, resistance to ozone etc.
The structure called the carcass in the middle of the belt conveys the pulling force and allows the belt to carry the load, the rubber between the carcass layers connects these layers and at the same time makes the layers waterproof. The tire on the underside prevents the belt from being crushed by impact caused by the load on the pulleys, prevents penetration of dirt into the belt and conveys the drive force taken from the drum to the carcass.
Conveyor pulleys have two tasks:
- Support to the belt carrying the material or on the empty belt on the return arm.
- When required
In belt conveyors, the elements that move the belt are pulleys and drums. In conveyors, two kinds of drums are used, which are the belt pulleys and auxiliary drums. In the simplest conveyor plant, there is a movement and a tail drum. The drum, which applies the rotational movement from an engine to the belt by friction and enables the conveying of the belt and thus the material, is called the “movement drum”. The winding angle measured on the contact surface of the belt with the movement drum is the most important factor that affects the conveyor characteristic of the conveyor. For this purpose, distortion drums are used. In addition, stretching drums are used to prevent the belt from sagging and to ensure its stretch. These drums used for deflection and stretching are also called da auxiliary drums Sap.
In order to provide the pulling force on the belt arms, a stretcher is required in the conveyor system. The stretch pattern is used for the following reasons:
- The belt does not slip on the drum where it takes action,
- The grooving of the belt does not deteriorate and does not hang more than necessary between the pulleys,
- To meet the elongation and shortening in the belt.
The small and small type of conveyors have a small, simple and inexpensive threaded stretcher, since the traction forces on the stretched and loose arms of the belt are small. Automatic stretchers should be preferred for conveyors with lengths exceeding 60 meters. These stretching devices can be weighted, hydraulic, pneumatic and electric. The simplest and most useful ones are weighted.
The fact that the belt conveyors are not loaded properly will result in empty and overloaded areas on the belt, thus reducing the capacity and causing the material to spill. Therefore, it is necessary to make the loading on belt conveyors properly. In conveyors fed by another belt conveyor, only the shape of the loading groove is sufficient. When the belt conveyors are loaded from silos or stock piles, the materials must be delivered properly.
The conveyor conveyed material must be evacuated from the belt at the transmission site. The discharge vessel is used for this purpose. These vessels may be in the form of scrapers, or in the form of unloading trolleys and discharge troughs.
If the material carried by the belt is wet and sticky, it will obviously be harmful to the drum, pulley or even the operating device on the road. It is also clear that if material is spilled on the material-free face of the belt, the material will cause wear on the drums and rollers due to the stretched belt. This material should be prevented from contacting the drum with the drum and in particular with the carrier rollers. For this reason, in the transmission of abrasive material, a sheet steel plate which is wider than the belt should be laid on the underside of the carrier roller groups and the material spilled from the belt edges should be prevented from falling into the return arm.
The conveyors and rollers of the conveyor and rollers and the power mechanism are placed on a frame. It is appropriate to use rolling profiles when designing chassis in continuous conveyors. For portable conveyors, chassis made of light profiles or pipes should be preferred.
