Structure and characteristics of single screw volume feeder

Single screw volume feeder according to the different materials, single screw volume feeder has many different forms of interchangeable screw for selection, feeder installed on the painted steel base, all the contact parts with the material are stainless steel parts, the feeder is easy to disassemble and clean up or replace parts. The unique patented design of the spherical hopper enables the material to flow uniformly into the screw from all directions in the spherical hopper, effectively preventing the accumulation of the material, while the horizontal stirring further improves the material flow to the screw propeller and makes the feeding more accurate. The feed screw is selected according to the material characteristics. The following table is the empirical value of the feed range (suitable for fluidity). For both ends of the feeding range, it is recommended to select suitable screws after testing.

The weightless feeder is composed of hopper, feeder (single and double axis screw feeder), weighing system and regulator. In operation, the hopper, material and feeder are weighed continuously together. As the material is delivered, the true weight loss rate is measured and compared with the desired weight loss rate (set value). The weightless feeder automatically corrects deviations from the set point by mediating the feed rate. Thus, materials can be fed continuously and accurately.
