Loss-in-Weight Flow Feeder Continuous Dosing System

$0.00

Consistently Accurate Product Dosing

Loss-in-weight feeders are ideal dosing systems for a variety of applications from bulk, dry materials to liquids and even poorly flowing materials. Whether it’s used in food or chemical production, high temperature or ATEX environments, Rice Lake Weighing Systems has a loss-in-weight feeder to meet your requirements

Depending on the material’s behavior, agitation might have to be added. This could be a flexible wall, an agitation screw, pneumatically moving plates, or air pads. Our expertise and customer support ensure the correct system is chosen to fit your application.

Fixed Dosing Systems

This loss-in-weight system is best for easy flowing, dry products with straightforward dosing. Dosing is typically done with a vibrating unit or an screw and optional paddles to gently agitate the materials and prevent product build-up. When paired with paddles, the screw and paddles can either operate from the same motor or separate motors, giving users complete control over the output of the dosing equipment.

Flex Dosing Systems

Using a hopper with a flexible PU (polyurethane) insert, a flex dosing system is an ideal solution for products that are easily damaged or difficult to extract. Agitators move against the flexible walls of the hopper to keep product moving, ensuring there are no build-ups or compacted material. Dosing with this system is done with an screw, though the size and style of the screw is determined by the type of product and desired flow rate.

Liquid Dosing Systems

For continuous liquid dosing, a loss-in-weight feeder and pump are paired with a floor scale to precisely weigh the liquid as it fills a barrel or an IBC (intermediate bulk container). Similar to other loss-in-weight systems, the weight indicator controls the dosing speed of the pump. Because the container is connected to the pump through a flexible hose, the liquid travels straight out of the container providing greater accuracy than a standard flowmeter.
