Self-cleaning and requiring minimal maintenance, McLanahan’s Wobbler Feeders feed oversized material at a controlled rate and scalp out the fine from the feed material. They are especially good with wet, sticky material that have a high percentage of clay. Wobbler Feeders can be used to accomplish feeding and scalping for industries such as coal, salt, gypsum, phosphate, limestone, bauxite, coke, quartz, granite, aggregate and other mineral processing applications, while increasing crusher output by scalping material fines to let crushers handle only material that needs to be crushed.
