Design of impact stone crusher machine
Impact stone crusher involves the use of impact rather than pressure to crush materials. The material is held within a cage, with openings of the desired size at the bottom, end or at sides to allow crushed material to escape through them. Impact stone crusher is used with soft materials, medium to hard stones and medium hard metallic ores.
