Why belt conveyor is important to the mining industry?
The belt conveyor system is a piece of equipment capable of continuously conveying materials. It has the advantages of strong transportation capacity, smooth operation, and simple structure. With the rapid development of the mining industry, the heavy-duty conveyor belt is widely used for its outstanding features of high-power, large capacity, automation, intelligent and high-speed.
Belt conveyor manufacturing process
What is a belt conveyor used for?
- The belt conveyor is widely used for conveying materials like coal, salt, ores, rocks, trash, sand, etc. It can transport various materials with a density of 0.5 t/m³ to 2.5 t/m³.
- The working temperature is generally at the range of 25°C to 40°C, and you should take corresponding protective measures when beyond the proper temperature ranges.
- It can be used to transport materials horizontally, obliquely upward and obliquely downward.
- The belt width, speed, groove angle, and inclination angle depend on the granularity of the material and the frequency of occurrence of large materials.
How does a conveyor belt work? (with video of worksite)
From the video, you can see that the conveyor belt is supported by the upper and lower carrying idlers, bypassing the head and tail rollers to form a closed loop. It uses the friction between the drive roller and the conveyor belt to transmit power to achieve material conveying.
The structures of industrial belt conveyor and the importance of its components
1. Belts of the belt conveyor
Different types of belt conveyors need a different- material belt. Conveyor belts are mainly made of rubber, PVC, urethane, neoprene, nylon, polyester, leather, etc. The belts which applied for the mining industry are consist of two layers in which the lower layer is known as the body and gives it a linear strength and shape. Various rubber or plastic compounds are used to make the cover.
2. Hallow shaft speed reducer
The driving device is to rotate the driver roller at a certain speed. Sometimes the motor speed is too high, which need a reducer to reduce the speed transmitted to the roller.
Structure: The power of the motor is directly transmitted to the reducer, and the hollow shaft of the reducer will be directly sleeved on the roller shaft.
Advantages of installing the hallow-shaft speed reducer:
- Good sealing, especially suitable for dust-proof places;
- It is easy to install, saves the width of the belt conveyor, and is widely used in Europe and America;
- Common power range: 1.5–4.5 kW
3. Long-belt head pulley and drive
Long-belt head pulley and drive is very different from that of the ordinary belt. The ordinary belt driving device generally uses a single drive, a low-voltage motor and a head roller as the driving roller, and the downstream belt conveyor uses the tail roller as the driving roller.
Long-belt head pulley and drive adopts double driving or multiple driving with most of them are high-voltage motors.
Considering the layout space and convenient maintenance, you can put the driving device on the ground and make it close to the belt's head or tail.
That is convenient for the centralized power supply of the adjacent belt conveyor, which makes head roller and tail roller only reversing rollers.
4. Belt turnover device
The belt turnover device turns the conveyor belt that has bypassed the head roller so that its working surface is facing upward without contacting the lower carrying idler. In this way, you can prevent the residue on the conveyor belt from being scraped down on the ground to pollute the working environment, which reduces the workload of manual cleaning.
5. Tension device
The function of the tension device is to tighten the belt for keeping its normal tension，and compensates the elasticity of the belt. The tension device of the long belt is mainly determined by the different forces which are caused by the belt direction and the layout space of the surrounding site.
Generally, you should make a tension device close to the driving roller so that the working parts can react quickly and show the best tension effect.
6. New- type carrying roller frame
The arched-lattice roller frame reduces the weight of itself by about 40% and improves its strength by about 10%. The structure frame is beautiful and easy to install.
High-quality parts and components are the key factors to prolong the life cycle of the belt conveyors, which can effectively improve productivity and bring you huge profits. FTM Machinery belt conveyor manufacturer can speed up your success.

Eight characteristics of belt conveyor:
- Can realize long-distance conveying
- Large conveying capacity
- Simple structure, less capital investment, and low operating cost
- The production line can be arranged horizontally, obliquely or curvedly in the horizontal direction and vertical direction. So, it can break terrain conditions, height limitation, and save a lot of time
- Simple operation, safe and reliable, easy to realize automatic control
- Conveyor with automatic inclined belt can unload automatically without manual unloading
- The speed of material movement can be carefully controlled, which resolves the problems of belt broken and damaged during the handling process
- The conveyor belt can move in both directions
Cases of belt conveyors (coal and sand)
Coal belt conveyor site in India
Coal belt conveyor system mainly used in coal mining, production, transshipment and processing.
| City | Material | Production (t/h) | Belt width (m) | Belt width (m) | Conveying speed (m/s) | Motor power (kW) | Cost (Rs) |
| Bhopal | Coal | 2,000 | 2.4 | 50 | 2 | 185 | 150,307 |
The Bhopal coal mine conveying site in India needed a large transportation volume and was processed in a complicated working environment.
We have designed a large-capacity belt conveyor (50*2.4) plant for our customers, which has fast transportation speed, strong carrying capacity, and is suitable for long-distance conveying. Besides, it can effectively reduce energy consumption and provide economic benefits.
Sand belt conveyor site in Pakistan
| City | Material | Production (t/h) | Belt width (m) | Belt width (m) | Conveying speed (m/s) | Motor power (kW) | Cost (PKR) |
| Karachi | Sand | 480 | 1.2 | 20 | 1.25 | 15 | 166,121.79 |
The output of this Pakistani customer is relatively small. We recommend to him the inclined rubber belt conveyor (20*1.2) with slope 18°. This machine equipped with walking wheels can move freely and save the disassembly time.
Because sand is very easy to produce dust, it is conveyed by a closed conveyor, which not only ensures the output but also improves the efficiency.
