Symons 4ft Cone Crusher
The Symons 4ft cone crusher is a common model of cone crusher. "4ft" usually indicates that the feed opening size or a certain key component size of this crusher is 4 feet (approximately 1.2192 meters).
This cone crusher generally consists of a frame, a transmission system, a discharge adjustment device, a lubrication system, a moving cone support system, a moving cone and a fixed cone, etc. Its working principle is as follows: The electric motor drives the bevel gear on the transmission shaft to rotate through the flexible coupling, causing the eccentric sleeve to rotate inside the central cylinder of the frame. The eccentric sleeve has a conical hole with a certain angle deviated from the rotation center line. Inside the hole is a conical bushing. The moving cone is supported by a bronze bowl-shaped spherical bearing, thus performing a swinging motion. The material falls from the feed box onto the distribution plate at the upper end of the moving cone and is evenly fed into the crushing cavity around the moving cone, where it is crushed by multiple impacts and compressions of the moving cone. The crushed material is discharged from the crusher in an open state through the discharge opening.
