Condition: new, functionality: fully functional, Year of construction: 2026, The wobbler feeder is a feeding system that delivers superior performance, especially when handling large, sticky, and moist materials. Its structure, consisting of rotating elliptical rods, creates a vibrating motion during material flow. This motion separates fine materials from larger particles and provides consistent feeding to crushers and screens. As a result, clogging is prevented and the overall efficiency of the plant is increased. Widely used in the mining, aggregate, and recycling industries, wobbler feeders are typically placed in front of primary crushers. This ensures that the material undergoes pre-screening in the initial stage. Its ability to operate without clogging, even with sticky and clayey materials, makes it an ideal solution for demanding conditions. Its mechanically simple design, ease of maintenance, and long-lasting performance keep operating costs to a minimum. With these features, wobbler feeders are a reliable choice for all plants requiring a continuous and balanced material flow.

The control system also managed the separations of the screws and controlled the screwdriver itself. The vibratory bowl is fully functional even without the PLC, the built-in vibratory bowl controller does not require PLC control. Process: Fasteners are filled into the bowl in bulk and conveyed upward by mechanical vibration (micro-throw principle). The vibratory bowl is automatically switched on or off depending on the fill level of the screw magazine. The screw is then conveyed by compressed air through a plastic hose to the downstream device. The feed impulse for each individual screw is triggered externally by the downstream device.
