sales@china-cfc.ccWobbler Feeder is used in aggregate and mining applications to sort the run-of-mine material before the primary crusher. This scalping of the feed reduces unnecessary wear on the primary crusher. Since scalping the feed reduces the amount of material going into the primary crusher, it also reduces the required size and capacity of the crusher needed. Depending on the application, they can be fed by an apron feeder or directly via trucks or loaders. They can also be used in secondary applications to separate already crushed feed material. CFTC Wobbler Feeder is available as a one or multi-stage device. Due to a modularization of the wobbler feeder length almost any sizes of separation surfaces may be realized. Plants of this type are suited for different operations in limestone, clay stone, coal, natural stone, salt, gypsum and other materials.
Especially with difficult to screen bulk feed such as moist material with loamy shales or clay Screening effect is enhanced by use of triangular rollers which are arranged on the shafts in a staggered configuration Achieves spiral transportation of the material Separation surface is formed by discs fitted to rotating rollers Rollers transport the material fed in, circulate and loosen it Separation of the fines effected by the gaps between individual rollers Coarse material is transported via the screen into the overflow.
The Wobbler Feeder consists of a frame, elliptical bars and a chain drive system used to rotate the bars. The bars are elliptical in shape and are timed at 90 degrees to the adjoining bar. The drive system connects all the bars with a double- or triple-strand chain that attaches to sprockets on each bar, maintaining the 90 degree timing. This maintains the gap, or opening, between the bars at the same dimension throughout the bar rotation. As material is moved from the feed end to the discharge end, the large lumps of material are forced up and down within the load, scrubbing against each other. This action forces any sticky material, such as clay, to be dislodged and enables it to pass through the openings between the bars. The rotation of the bars also moves the material from the feed end to the discharge end with continuous scrubbing the full distance.
Note: The capacity may vary with different materials and feeding sizes.
