Feeder breakers are primary crushers with pick mounted roll crushers combining with a chain conveyor. They are designed to act as first phase crushers of mined mineral including coal, limestone, potash, gypsum and PET coke down to a suitable size for continuous transport. They can be either mobile or static machines and employ a variety of “running gear”.
