Volumetric feeder provides low cost and easy option in batch or continuous applications, especially when the bulk density of the fed material is consistent or when precise feed accuracy is not so important for the quality of end product. Frequently volumtric feeder is used in gain-in-weight batch application since higher accuracy can be achieved. When process requirement is more demanding, volumtric feeder with gravimetric scale and loss-in-weight control can be used. Our volumetric feeder can provide reliable and stable performance. Single screw feeder is the best choice for free flowing materials, while twin screw feeder is the the best solution for difficult-handled materials. We have a full range of volumetic feeders with a number of models and different-sized hoppers to meet your specified requirements. Single screw volumtric feeder is applied for pellet, granule and free flowing powder to provide volumetric feeding. A series of interchangeable screws are availabel for our single screw feeder to meet the requirements of different materials being fed. The feeder is placed on the painted steel plate. All the feeder parts which contact fed material are made of stainless steel. The volumetric feeder can be disassembled easily for cleaning or changing parts. There are two types of hopper shape: symmtrical and asymmetrical. The hopper design can allow material from all directions to flow evenly to the screw, which can avoid material build-up and make feeding more accurate. The most suitable screw type is determined by the characteristics of fed materials. Therefore, please provide detailed information about your material when inquiring.
