The working principle of the quantitative feeder

A quantitative feeder is a type of feeding equipment commonly used in the industry to accurately measure and feed materials. The device is designed with a metering mechanism that ensures a precise and consistent flow of material. It is suitable for feeding various types of materials, including powders, granules, and pellets, in a wide range of industries, such as chemical, mining, and construction.

The working principle of the quantitative feeder is based on the loss-in-weight feeding system, which operates by measuring the weight of the feeder hopper and the material flowing into it. The feeder uses a load cell or strain gauge to continuously monitor the weight of the hopper and adjusts the flow rate of the material accordingly. The feeder is programmed with a target weight or flow rate and automatically adjusts the material flow to meet this target.

The quantitative feeder consists of several key components, including the feeder hopper, the metering mechanism, the load cell, the control system, and the discharge mechanism. The feeder hopper is where the material is initially placed, and the metering mechanism controls the flow rate of the material. The load cell continuously monitors the weight of the hopper and the material, and the control system adjusts the flow rate to maintain the desired weight or flow rate. The discharge mechanism is responsible for delivering the material to the downstream process.

The advantage of the quantitative feeder is its high accuracy, consistency, and reliability. It ensures a precise and consistent flow of material, which is critical in many industrial processes. The feeder can be customized to meet the specific requirements of different applications, such as high-temperature environments or corrosive materials.

In summary, the quantitative feeder is an essential piece of equipment in many industrial processes, providing precise and consistent material feeding. Its working principle is based on the loss-in-weight feeding system, which monitors the weight of the hopper and the material and adjusts the flow rate accordingly. The feeder consists of several key components, including the feeder hopper, metering mechanism, load cell, control system, and discharge mechanism.
