Gentle high rate gravimetric feeding or metering of free flowing or friable products

Weigh Belt Feeders are relatively simple, extremely reliable gravimetric feeders providing high feeding precision and efficient process monitoring. They can be used as a feeder, batcher, or meter. The SWB is the perfect solution for wild flow metering, where headroom is limited, or when feeding friable material that may be damaged by other feeding methods. This compact gravimetric feeder can handle large volumes of bulk material with different flow characteristics.

Optionally, the SWB-300 and SWB-600 offer continuous online taring by using two weigh modules. This reduces costly maintenance, line shutdowns and laborious manual calibration while at the same time substantially improving long term accuracy and stability.

Benefits & Features

  • Gentle gravimetric feeding of free flowing and friable bulk material
  • Suitable for handling materials with special characteristics, e.g. materials with very low melting points, powders with wax additives, or very abrasive materials
  • Ideal for large quantities
  • Online taring option available
  • No refill device required
  • Compact height allows easy fit in low headroom situations
  • Comparatively low price for high mass flow feed rates

Areas of Application

The Smart Weigh Belt Feeder SWB is used for continuous controlled gravimetric feeding of bulk materials. The most typical application is for feeding/weighing into a continuous process. By utilizing different control software, the SWB can also be used to feed material into a batch system.

Due to their operating principle weigh belt feeders are often a good choice when feeding relatively free-flowing materials not requiring containment. The SWB offers gentle material handling, an important benefit compared to other feeding devices, such as the screw feeder, when handling certain materials:

  • Flakes (e.g. corn flakes, bran flakes, and wheat flakes)
  • Lumpy bulk solids (e.g. vegetables and fruits)
  • Shear sensitive materials (e.g. corn flakes, frozen vegetables and frozen fruit)
  • Highly abrasive bulk solids (owing to a low friction coefficient applied to the materials)
  • Low melting bulk solids (e.g. fat flakes)

Design Features

Weigh belt feeders operate by continuously weighing a moving bed of material on its short conveyor, and controlling belt speed to result in the desired flow rate at discharge. Therefore, weigh belt feeders can achieve high rates while remaining compact.

The available models are divided into two rate categories:

  • Mid-rate: SWB-300 and SWB-600
    The SWB-300 and SWB-600 are available with housing (model -N) or as open frame models (model -O)
  • Hi-rate: SWB-650, SWB-800, SWB-1000

Open frame models are typically used in food applications. They are made of stainless steel and especially easy to clean.

Available Models

SWB-300-N, mid-rate Smart Weigh Belt Feeder with housing

The SWB-300 features a 300 mm wide belt.  The stainless steel belt conveyor frame includes the primary material weigh bridge and an optional secondary continuous auto tare weigh bridge. The conveyor frame is removable on a telescopic support structure.
