Weigh feeder
Efficient material feeding is essential for stable production, reduced waste, and optimized performance. Our weigh feeders deliver accurate, consistent, and automated dosing, ensuring that bulk materials are fed at the right rate, every time. Designed for demanding industrial environments, our solutions integrate real-time weight monitoring, adaptive belt control, and intelligent automation, making them the preferred choice for cement plants, mining operations, power generation, and chemical processing.What is a weigh feeder?
In short, a weigh feeder is an automated weighing system that helps to streamline the production process in your facility. A weigh feeder consists of a conveyor belt with a weighing section supported by rollers coupled to one or more load cells. It is used to measure the weight of the product conveyed on the belt conveyor. The weight of the product is determined by weighing the belt load and measuring the belt speed. In most applications, the belt speed is constant while the feed rate to the belt weigher is regulated.How does a weigh feeder work?
There are different types of weigh feeders, but the basic principle involves measuring the weight of the material as it passes through the weigh feeder system. Weigh feeders operate by continuously weighing a moving bed of material on its conveyor and controlling belt speed to result in the desired flow rate at discharge.What are the different types of weigh feeders?
Jesma offers a variety of weigh feeders for different applications and to ensure that we have a solution that meets our customer’s needs. For example, the JesBelt®A for approved weighing, the JesBelt®S for optimum lifetime non-approved weighing and the JesBelt®F1 for heavy duty application industries and easy belt change and cleaningThe benefits of a weigh feeder
A weigh feeder from Jesma will benefit you by providing precise control, optimum reliability, and a long lifetime with high accuracy. Our weigh feeders feature an incremental encoder (tacho) mounted on the idle roller to improve continuous monitoring of the belt and ensure an immediate alarm signal for any belt drive irregularities. Over-dimensioned load cells secure high accuracy, even with uneven material flow. Additionally, a weigh feeder is also customizable, with options for individual design, such as ATEX-compliant components, manual or automatic dust trays, flexible rims to eliminate product spills, and belt tracking switches, depending on the model you choose.The difference between belt weighers and weigh feeders
While the two share similarities in measuring material weight on a conveyor belt, the key difference between a belt weigher and a weigh feeder lies in their purposes. A belt weigher provides a cumulative measurement of the total material weight passing a designated point, while a weigh feeder offers dynamic control by continuously adjusting belt speed to maintain the desired material flow rate. For more information, we also have an article about understanding the distinction between the two.Why accuracy matters in bulk material feeding
Feeding bulk materials might seem straightforward, but even minor variations in feed rate can cause major production issues. Poorly controlled feeding can lead to:- Overfeeding – Wastes raw materials and increases costs
- Underfeeding – Causes product inconsistencies and production delays
- Unstable flow – Leads to blockages, fluctuations, and inefficiencies
- Frequent recalibration – Increases downtime and maintenance costs
Industry-specific weighing solutions
Each industry has unique feeding challenges, and one-size-fits-all solutions don’t work. That’s why our weigh feeders are customized for specific applications.Industries We Serve:
