According to the above-mentioned various top spindle bearings, the structure of the red star crusher is better. It has two bushes, and borrows the lower thread on the inner bushing to compress the lining. Remove the threads on the spindle that compress the lining plate to increase the strength and reduce the number of machining operations. The vertical cone of force and the vertical force of the crushing force of the hydraulic gyratory crusher spindle are supported by the spherical bearing at the bottom of the vertical shaft. Almost all crushers are like this, except that the former Soviet Union used the vertical axis of the hydraulic gyratory crusher under the main shaft. Replaced by spherical bearings, its structure is simple. The use of roller motion instead of sliding of the spherical bearing can reduce wear and prevent the piston from receiving lateral forces.
Jaw crusher main parameters are structural parameters and performance parameters. Structural parameters include feed, discharge port size, angle of engagement, height of crusher cavity, eccentricity and dynamic cone travel, dynamic cone bottom diameter, precession angle and dynamic cone suspension height; performance parameters have dynamic cone oscillation frequency, productivity (production capacity ), crushing power and power and weight. When the feed cone size B uses a movable cone near the fixed cone, one end of the two cones is expressed as the distance from the feed port level. Discharge port size b is represented by the distance between the lower end of the two truncated cones at the discharge port level. B represents the size of the crusher and b represents the minimum size of the discharge opening (closed discharge opening size). When designing the crusher, the maximum particle size of the raw materials is known, so ensure that the largest particles of the material can enter the crusher smoothly.
