Precision Conveyor Belt Weighers for Continuous Load Monitoring

On this page you will find Belt Weighing solutions for monitoring constant loads on conveyor systems. These scales are designed to constantly measure flow rate and total load of bulk products as they are transported along a conveyor belt.

Our belt weighing scales are designed to fit under conveyor belts, and can be fitted to existing installations.

FAQs

What are conveyor belt weighers and how do they work?

Conveyor belt weighers (also called belt scales or weigh frames) are precision weighing systems that fit beneath a conveyor belt to continuously measure the load passing over it. Load cells built into the weigh frame track the weight of material on a short section of belt, combine this with belt speed, and feed real-time flow rate and total load data to a digital display or control system.

What is the purpose of a belt weigh frame on a conveyor?

The weigh frame replaces a standard section of conveyor idler with a weighing platform, allowing the belt to keep running exactly as before while the load cells capture continuous, in-motion weight data. This means you get accurate throughput figures without ever stopping the belt or handling material separately.

What are the benefits of belt weighers compared to static weighing methods?

Belt weighers give you continuous, real-time weight and flow rate data rather than a single static reading, so you can monitor production as it happens. This can improve stock control, cut down on waste, support tighter quality control, and make it much easier to spot process issues before they become costly.

Where are conveyor belt weighers typically used?

They’re widely used in mining, quarrying, agriculture, food processing, manufacturing, waste management, and any industry that relies on conveyors to move bulk materials. Anywhere accurate, continuous throughput data matters, a belt weigher is a great fit.

Can belt weighers be fitted to an existing conveyor?

Absolutely! MWS belt scale weigh frames are designed to fit under conveyor belts and can be retrofitted to existing installations, so you don’t need to replace your whole conveyor system to add accurate in-motion weighing.

What civil works or installation is required for a belt weigher?

In most cases, installation is straightforward. Models such as the BS311 are designed to fit directly onto the existing conveyor frame using just four bolts, while larger systems may need some additional bracketry depending on belt width and capacity. MWS can advise on the best fit for your conveyor and support you through installation.

What capacities and belt widths are belt weighers available in?

MWS offers a range of belt scale weigh frames, from the BS311 for lighter to medium duty conveyors, up to the BS143 and BS221DB for medium to heavy capacity applications. The right option for you will depend on your belt width, conveyor speed, and the loads you need to measure.

How accurate are conveyor belt weighers?

Belt weighers are built to deliver high accuracy continuous weighing, even under demanding, heavy-duty conditions. Models like the BS143 are specifically designed for high accuracy applications, giving you dependable flow rate and total load figures you can rely on for stock control and process management.

How are belt weighers serviced and calibrated over time?

To keep your belt weigher performing accurately, it’s important to carry out regular inspections, keep the weigh frame and idlers clean, and schedule routine calibrations. MWS offers servicing and calibration support to help maintain accuracy and compliance over the lifetime of your system. Learn more about our calibration services.

Can belt weighers be customised for specific applications?

Yes, indeed! Belt scale weigh frames can be tailored to suit specific belt widths, capacities, conveyor frame dimensions, and indicator requirements, ensuring the system integrates smoothly with your existing conveyor and meets your operational needs.

What are Conveyor Belt Weighers?

Conveyor belt weighers, also known as conveyor belt scales or weigh feeders, are devices used in various industries to measure the flow rate and total amount of material being transported on a conveyor belt. They provide real-time data about the weight of the material moving along the belt, allowing for accurate monitoring and control of production processes.

Benefits of Conveyor Belt Weighers

These weighers are commonly used in industries such as mining, agriculture, food processing, manufacturing, and more. They offer several benefits, including:

  1. Accurate Material Measurement: Conveyor belt weighers provide accurate measurements of the material’s weight, allowing for precise inventory tracking and process control.
  2. Process Monitoring and Control: Industries can use the data from conveyor belt weighers to monitor the flow rate of materials and adjust production processes accordingly. This ensures that the right amount of material is being processed or transported.
  3. Quality Control: In industries where product quality is crucial, conveyor belt weighers can be used to ensure that the correct amount of material is used in each batch, leading to consistent product quality.
  4. Efficiency Improvement: By having real-time information about material flow, companies can optimize their production processes, reduce material wastage, and improve overall operational efficiency.
  5. Data Logging and Reporting: Conveyor belt weighers often come with data logging and reporting capabilities, allowing companies to generate reports on material usage, flow rates, and production trends. This data can be valuable for analysis and decision-making.
  6. Integration with Automation: Conveyor belt weighers can be integrated with other automation and control systems, enabling seamless communication between different parts of the production process.

Types of Conveyor Belt Weighers

There are different types of conveyor belt weighers, including:

  1. Belt Weighing Scales: These are systems that measure the weight of the entire conveyor belt and the material on it. They typically use load cells installed underneath the belt to measure the total weight.
  2. Weigh Feeders: Weigh feeders are used to measure and control the flow rate of material on a conveyor belt. They can adjust the conveyor speed based on the desired feed rate, ensuring a consistent flow of material.
  3. Impact Weighers: Impact weighers use the impact force of the material falling onto the conveyor belt to estimate its weight. These are commonly used when the material is abrasive or difficult to measure using traditional load cells.
  4. Nuclear Weighing Systems: Some industries use nuclear-based systems that measure the material’s weight using radiation absorption or transmission. These systems are highly accurate but require special handling and regulations due to their use of radioactive isotopes.

Overall, conveyor belt weighers play a crucial role in various industries by providing accurate and real-time data about material flow, enabling better process control, quality assurance, and operational efficiency.
