Cone crushers have been developed to crush feed materials into desired end products efficiency reliably and economically. Continuous research and product development has taken advantage of the simple concept of the floating shaft type design to ensure reliability. The exceptionally large diameter of the main shaft and the heavy-duty mainframe ensure robustness. Cone crushers are designed to give maximum performance in a wide variety of crushing. Self-contained oil reservoir and externally-mounted oil pump and motor provide lubrication under pressure to all moving parts.
