Stable and reliable continuous and intermittent feeding schemes

The volumetric feeder provides a low-cost and simple feeding solution for continuous and intermittent feeding applications, provided that the bulk density of materials is uniform and the quality of the final product does not require strict feeding accuracy.

Volumetric feeders are often used in applications where batch weight is increased, resulting in higher feeding accuracy. When the precision requirements for production and processing are very high, screw feeders with weighing sensors and weight loss controllers can improve precision to a new level.

In automation systems, we provide you with reliable volumetric feeders. Single screw volumetric feeders are the best choice for materials with good flowability, while twin-screw volumetric feeders are the best choice for solid materials with poor flowability and difficult feeding. To cater to a wide range of feeding volumes, we offer a variety of different models of volumetric feeders and hopper sizes for you to choose from.

Single screw:

Single screw volumetric feeder

The single screw volumetric feeder of the automation system can be used for feeding large, small particles and powders with good flowability.

According to the different materials, the single screw volumetric feeder has many interchangeable screws to choose from. The feeder is installed on a painted steel base, and all parts in contact with the material are made of stainless steel. The feeder is easy to disassemble, clean or replace components. The unique patented design of the spherical hopper ensures that materials flow evenly from all directions into the screw, effectively preventing material accumulation. Horizontal mixing further improves the flow of materials towards the screw propulsion section, making feeding more precise.

The feeding screw is selected based on the characteristics of the material. The following table shows the empirical values of the feeding range (applicable to materials with good fluidity). For those located at both ends of the feeding range, it is recommended to test and select the appropriate screw.

Twin screw: Twin screw volumetric feeder

The twin-screw volumetric feeder of the automation system is widely applicable to various materials, including providing volumetric feeding solutions for powder, fiber, and sheet materials with poor flowability.

All components in contact with the material are made of stainless steel. This feeder is easy to clean and replace components. The unique patented design of the spherical hopper ensures that materials flow evenly from all directions into the screw, effectively preventing material accumulation. Horizontal mixing further improves the flow of materials towards the screw propulsion section, making feeding more precise. When feeding materials with poor fluidity and easy bridging, vertical mixing can also be considered.

For those located at both ends of the feeding range, it is recommended to test and select the appropriate screw.

High precision weighing sensors and control technology for weighing feeders

The automation system applies high-precision and advanced Western weighing technology to the weighing feeder. The weighing module of the feeder provides users with high-precision weighing in the milligram range, which is less than seconds, and can be used in harsh industrial environments.

The weight loss feeder of the automation system is supported by our company's R&D department's patented technology software, providing you with a continuous, accurate, reliable, and repeatable feeding solution. The weighing controller and operating interface allow for individual and comprehensive control. Each feeder has an independent control board, and the connection between the control board and the operating interface is supported by industrial protocols.
