TDG Speed Adjustable Conveyor Belt Scale, Speed Adjustable Quantitative Feeder Conveyor Belt Scale

The TDG Speed Adjustable Conveyor Belt Scale is an industrial weighing and feeding system designed for continuous measurement and controlled transportation of bulk materials. By combining a conveyor belt with a weighing mechanism and adjustable-speed drive, the equipment can help users monitor material flow while maintaining a stable and controllable feeding rate.

The Speed Adjustable Quantitative Feeder Conveyor Belt Scale is suitable for production lines where accurate material feeding, continuous weighing, and automatic flow control are important. Typical applications include coal handling, mining, mineral processing, cement manufacturing, power plants, chemical processing, metallurgy, building materials, grain handling, and other bulk material industries.

Unlike a conventional conveyor used only for transportation, a belt scale or weigh feeder provides measurement information during material movement. The speed-adjustable design also allows the feeding rate to be changed according to production requirements.

What Is a TDG Conveyor Belt Scale?

A conveyor belt scale is a continuous weighing system installed on a belt conveyor. It measures the weight of material traveling across the weighing section and combines this information with belt speed to calculate the material flow rate.

The TDG Speed Adjustable Conveyor Belt Scale is designed for applications where transportation and quantitative feeding need to work together. Depending on the configuration, the system can continuously monitor material throughput and provide signals to a control system.

A typical system may include a weighing frame, load cells, belt speed sensor, conveyor belt, drive motor, speed control system, feeding hopper, and electronic weighing controller.

What Is a Speed Adjustable Quantitative Feeder?

A Speed Adjustable Quantitative Feeder is designed to deliver bulk materials at a controlled and adjustable rate. By changing belt speed, the operator or automatic control system can regulate the amount of material transported per unit of time.

This function is especially useful in batching, blending, proportioning, dosing, and continuous production processes.

For example, if a cement production line requires a specific raw material flow rate, the feeder can be configured to provide controlled material delivery while the weighing system monitors the actual throughput.

How Does the Belt Weigh Feeder Work?

Bulk material enters the belt through a hopper, chute, or upstream feeding device. As the material travels over the weighing section, load cells detect the material load on the belt.

At the same time, a speed sensor monitors belt velocity. The weighing controller combines belt loading and belt speed information to calculate the instantaneous material flow rate.

The control system can then display parameters such as:

Belt speed
Material flow rate
Accumulated material quantity
Belt load
Feeding rate
Total production quantity

When the equipment is used as a quantitative feeder, the control system can adjust the belt speed to maintain the desired feeding rate.

Main Components

A TDG Speed Adjustable Conveyor Belt Scale can include several key components:

Conveyor belt
Weighing frame
Load cells
Belt speed sensor
Drive motor
Speed reducer
Variable-speed drive
Feeding hopper
Belt support rollers
Electronic weighing controller
Control cabinet
Discharge chute
Safety protection components

The weighing frame and load cells are important for detecting the material load. The speed sensor provides belt velocity information, while the controller processes the signals and calculates the material flow.

Continuous Weighing and Quantitative Feeding

One of the major advantages of this equipment is the ability to combine continuous weighing with material feeding.

A conventional conveyor transports material but does not necessarily provide real-time production measurement. A conveyor belt scale adds weighing functionality, allowing users to monitor throughput during transportation.

A quantitative belt feeder adds another level of control by adjusting belt speed according to the target feeding rate.

This combination is useful in processes that require stable material proportions, consistent production rates, or automatic feeding control.

Industrial Applications
Mining and Mineral Processing

Mining operations use belt scales and weigh feeders to monitor ore, coal, limestone, aggregates, and other bulk materials. Continuous weighing can provide production data for crushing, screening, conveying, and processing operations.

Cement Plants

Cement plants require controlled feeding of limestone, clay, gypsum, coal, and other raw materials. A quantitative belt feeder can help regulate material flow into crushers, mills, mixers, and other process equipment.

Coal Handling

Coal-fired power plants, coal preparation facilities, and bulk terminals can use conveyor belt scales to monitor coal transportation and feeding rates.

Aggregate and Quarry Plants

Sand, gravel, crushed stone, and other aggregates can be continuously weighed during transportation. The equipment can help operators monitor production output and material flow.

Chemical Industry

Powdered and granular raw materials often need controlled feeding for batching and continuous processing. A speed-adjustable belt feeder can provide controlled material delivery.

Metallurgy

Steel plants and metallurgical facilities can use quantitative feeders for ore, coke, limestone, and other bulk materials requiring controlled feeding.

Building Materials

Industrial production lines for lime, bricks, ceramics, and other construction materials can use belt weighing and quantitative feeding equipment.

Key Advantages
Adjustable Feeding Rate

The belt speed can be adjusted according to production requirements, allowing the equipment to function as a controlled quantitative feeder.

Continuous Material Weighing

The weighing system measures material flow while the belt is running, eliminating the need to stop the conveyor for every measurement.

Integrated Transportation and Feeding

The conveyor performs material transportation while the weighing and control system manages material flow.

Real-Time Production Data

The electronic control system can provide information about instantaneous flow rate and accumulated material quantity.

Automatic Control

How to Select the Right Belt Scale and Quantitative Feeder

Several parameters should be considered before selecting a TDG conveyor belt scale.

Material Type: Provide the exact bulk material, such as coal, limestone, iron ore, cement, grain, or aggregate.

Material Density: Bulk density influences the required belt loading and feeding configuration.

Required Capacity: Specify the minimum, normal, and maximum feeding rates when possible.

Belt Width: The conveyor belt width should match the required material throughput and installation conditions.

Belt Speed: Determine the desired operating speed and speed adjustment range.

Feed Size: Particle size and material characteristics influence hopper and chute design.

Weighing Accuracy: Define the required measurement accuracy according to the production process.

Installation Location: The system can be configured for different conveyor layouts and process environments.

Control System: Determine whether local control, remote control, PLC integration, or automatic flow-rate regulation is required.

Installation and Maintenance

The conveyor belt scale should be installed on a stable and properly aligned conveyor section. The weighing area should be protected from unnecessary mechanical vibration and external interference.

Before commissioning, check belt alignment, load cell installation, speed sensor positioning, conveyor tension, and electrical connections. Calibration should be performed according to the equipment manufacturer's procedures and operating conditions.

Regular maintenance should include inspection of load cells, rollers, belt condition, speed sensors, bearings, drive components, and electrical connections.

Material buildup around the weighing section should be removed because excessive accumulation can affect weighing performance. Operators should also monitor belt tracking and mechanical vibration.
