How to Choose Heavy Duty Belt Conveyor

A heavy duty belt conveyor is widely used in mining, coal, aggregate and metallurgy industries for continuous transportation of heavy and bulk materials.

When you choose heavy duty belt conveyor, you should not only focus on conveying capacity. It is necessary to confirm proper equipment configuration by combining material characteristics, conveying route, belt specifications and driving power.

How to Choose Heavy Duty Belt Conveyor for Different Materials

Materials vary in particle size, weight, moisture and temperature, which bring different requirements for the conveyor belt and equipment structure. When you choose heavy duty belt conveyor, pay close attention to whether the material will abrade the belt, bring strong impact or stick to the belt during conveying.

How to Match Conveying Capacity, Belt Width and Belt Speed

Conveying capacity is a key reference when you choose heavy duty belt conveyor. Generally speaking, higher conveying capacity requires larger belt width and running speed. These parameters cannot be determined separately, and you also need to consider material bulk density, maximum particle size and loading cross-section.

Belt width mainly determines the loading space for materials. For large lump ore, enough width should be reserved to prevent material spillage. For fine materials such as coal powder and sand, confirm the width according to bulk density and actual loading volume.

Belt speed affects the throughput per unit time. Higher speed can boost conveying capacity, yet excessive speed may lead to material spillage, dust emission and accelerated equipment wear.

Therefore, you cannot simply raise the speed to meet production targets. Belt width, speed and material load should be well matched when you choose heavy duty belt conveyor.

Differences Between Horizontal, Inclined and Long-distance Conveying

Conveying route directly determines the driving type, belt structure and tension configuration of the heavy duty belt conveyor. Different routes have different priorities for consideration when you choose heavy duty belt conveyor.

Which Conveyor Belt to Select for Different Working Conditions

When you choose heavy duty belt conveyor, the conveyor belt is in direct contact with materials. Its material and surface structure should fit the application environment. Common types and their applicable scenarios are as follows:

How to Determine the Motor Power for Heavy Duty Belt Conveyor

Motor power cannot be decided only by conveying capacity. It is also related to conveying distance, lifting height, material weight and running resistance.

For example, with the same throughput, horizontal conveying and upward inclined conveying require different motor power. Inclined conveying needs extra power to lift materials besides overcoming running resistance of the belt and materials. Higher lifting height usually means larger required driving power when you choose heavy duty belt conveyor.

Besides, take the starting mode and running cycle into account. If the equipment frequently starts under full load, check the starting torque of the motor. For long-time continuous operation, consider the motor duty cycle and heat dissipation to avoid long-term overload.

In short, the motor power of a heavy duty belt conveyor should be calculated comprehensively based on actual throughput, route conditions and operating load, instead of adopting a fixed power value simply according to conveying capacity.

To sum up, when you choose heavy duty belt conveyor, make sure the conveying capacity, belt specifications, driving power and working conditions match each other. Do not blindly pursue a wider belt or a larger motor.
