Roll Crushers
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.
