The basic structure and working principle of the coarse, medium and fine crusher cone crushers are roughly the same, so they are collectively referred to as cone crushers . The construction of the spring cone crusher is shown below: The spring cone crusher consists of a moving cone and a fixed cone to form a crushing chamber. The movable cone is press-fitted on the main shaft (vertical shaft). One end of the spindle is inserted into the tapered hole of the eccentric bushing. Eccentric bushing tapered hole with bronze bushings or nylon liner. When the transmission gear drives the eccentric bushing to rotate, the main shaft deep into the eccentric bushing drives the movable cone to perform the swinging motion, so that the movable cone cone surface and the fixed cone are separated from each other, and the crushing and discharging are generated. The adjusting device and the locking mechanism for the spring cone crushing are mainly composed of an adjusting ring, a supporting ring, a locking nut, a pushing cylinder and a locking cylinder. The support ring is mounted on the upper part of the frame and is attached to the frame by means of a spring around the crusher. When the crusher is working, the high-pressure oil enters the lock cylinder to raise the piston, and the lock nut and the adjusting ring are slightly jacked up, so that the zigzag threads of the two are closely attached to each other. When adjusting the discharge port, the lock cylinder should be pressed to loosen the zigzag thread, then the hydraulic system is actuated to push the cylinder to move, thereby rotating the adjustment ring to the left or right, and the fixed cone is raised by the serrated thread drive. And down, to achieve the purpose of adjusting the discharge port. The safety protection measures are the spring group installed around the frame as a safety device. When the non-crushing object enters the crushing cavity, the support ring supported on the spring and the adjusting ring are lifted up to compress the spring, thereby increasing the distance between the movable cone and the fixed cone, and increasing the size of the discharge port, Discharge non-broken objects to avoid damage to the body. The spring cone crusher is widely used due to its smooth operation, continuous operation, large productivity and crushing ratio, low power consumption, and automatic uniform feeding device. However, when dealing with wet ore with high viscosity and high mud content, the discharge port is easily blocked and affects normal work.
