Reliable feeding solution for free-flowing bulk materials

The single-screw feeder is suitable for granular materials and powders with good fluidity, and the single-screw volumetric feeder can be used for feeding large and small particles and powders with good fluidity. Volumetric screw feeders are the most common and economical feeders on the market. Zhengzhou Batte provides a variety of single and twin screw volumetric and gravimetric feeders to meet your various feeding requirements and solve your material conveying problems. Some models are suitable for quick material changeover and can be configured to accommodate different material properties. Other models have specially designed cleaning properties to meet the hygienic needs of the food and pharmaceutical industries.

The volumetric feeder provides a low-cost and simple feeding solution for continuous and intermittent feeding applications where the bulk density of the material is uniform and the quality of the final product is not critical to feeding accuracy. Volumetric feeders are often used for batch weight gain applications, which allow for higher feeding accuracy. When the production process requires very high precision, the screw feeder with load cell and loss-in-weight controller can increase the precision to a new level. Single-screw volumetric feeders are the choice for materials with good fluidity, while twin-screw volumetric feeders are the choice for solid materials with poor fluidity and difficult to feed.

Volumetric screw feeders

Depending on the material, the single-screw volumetric feeder has many different forms of interchangeable screws to choose from. The feeder is installed on a painted steel base, and all parts in contact with the material are stainless steel parts. The feeder is easy to disassemble for cleaning or replacing parts. The unique spherical hopper design makes the material flow into the screw evenly from all directions in the spherical hopper, effectively preventing the accumulation of the material, and the horizontal stirring further improves the flow of the material to the screw propeller, making the feeding more accurate.

The feeding screw is selected according to the material characteristics. The table above is the empirical value of the feeding range (applicable to materials with better fluidity). For those at both ends of the feeding range, it is recommended to select the appropriate screw after testing.
