Smart Weigh Belt (SWB) Feeders are a key component used for the weighing of a variety of bulk solids in a wide range of processes. The most typical application is for feeding / weighing into a continuous process. The process material may enter the Smart Weigh Belt directly from an upstream hopper or via a prefeed device like a screw feeder.
View Catalog Page
The Smart Weigh Belt can be used as a feeder, batcher, or meter. By utilizing different control software, the Smart Weigh Belt can be used to feed material into a batch system. For inventory control or metering, the Smart Weigh Belt can be placed into a constant speed configuration to measure or totalize the amount fed into a process.
The Smart Weigh Belt offers gentle material handling, an important benefit compared to other feed devices like a screw feeder when handling the following materials:
Flakes (e.g. corn flakes, bran flakes, and wheat flakes)
Lumpy bulk solids (e.g. vegatables and fruits)
Shear sensitive materials (e.g. corn flakes, frozen vegetables and frozen fruits)
High abrasive bulk solids - due to a low friction coefficient applied to the materials
Low melting bulk solids (e.g. fat flakes)

In gravimetric feeding, dry bulk material or liquid is fed into a process at a constant weight per unit of time since weight is a variable that can be captured by a weighing module. Consistent control and complete monitoring are possible. In principle, gravimetric feeding combines monitoring of the feeding process with a feedback loop that enables accurate material control.
Typical application:
Precise feeding and blending of materials is a critical part of the process when manufacturing reinforced thermoplastics. Typical applications require the blending of several granular materials with one or two powder materials within a compact area at the throat of an extruder. Maintaining a steady and precise level of blended material above the throat of the extruder is also a requirement.

"Better-Weigh®" Batch/Continuous Weigh Feeders are designed to provide feeding in either batch or continuous mode depending upon the arrangement of the feeder's control electronics. In batch mode, the batch controller is used to control the fast (bulk) and slow (dribble) speeds of the feeder. Accuracies of ±0.5% can be easily achieved in 2 lb. or less batches, and ±0.25% with 3 lb. or greater batches with time spans of 30 to 90 seconds. In continuous mode, the feeder's electronic controller is used to constantly monitor loss-ofweight of material per time in order to maintain a continuous loss-of-weight with an accuracy of ±0.25% to 0.50%.
Features/Benefits
Accuracy: +/- 0.25% to 0.50%

In principle, volumetric feeding is the simplest, most economical feeding solution available. Bulk material is held in a hopper and constantly fed into a process per unit of time. A gravimetric feed rate may be inferred through a calibration process where a timed sample is taken and weighed, and screw speed adjusted accordingly. Although there is no weight feedback to assure feeding accuracy over time, this may not be a concern for materials with consistent bulk density.
K-Tron offers three choices in volumetric feeders: the highly accurate bulk solids pump (BSP), single screw feeders and twin screw feeders. K-Tron volumetric feeders come in a wide variety of of sizes and configurations to meet your application requirements.
