ZGMn Crushing
As we all know, the important role of linear are: 1. Blunt. enhance the medium grinding the ball y parrafo 2, play the role of abrasive, 3, protect the grinding cylinder. When we choosing linear, the main consideration is to enhance the role of the grinding media, the average trajectory. The accessories which make linear are mainly: chrome molybdenum alloy steel, alloy steel, high chrome cast iron, manganese steel, rubber, polyurethane, etc. Horowitz shines more light on the discussion. research not as a source, but as a related topic. The shape are convex edge, corrugated, angular spiral, and so on.
When the crushing is the main factors need consider, we exigir linear s grinding body is strong, elected at the same time the lining should have good shock resistance, high manganese steel ZGMn13 sufficient impact toughness, but not wear and easy to deform, and now Most have switched to dual-medium quenching process in alloy steel or chrome molybdenum alloy steel liner. Comparing to several wear-resistant materials to the process of double quenching medium alloy steel the best performance and longest life, the major domestic manufacturers are: Zhangjiagang Hanson of the Zhumadian force wins, the superiority in the large and medium-sized mill is more evident and the price ratio is the highest. After discharging non-debris pipes, due to the spring-damper is large, spring can only move back the cone slowly towards to the original location, for avoiding the impact and reducing the wear of the linear. When the non-broken materials go through the crushing chamber, the deformation of the annular spring is the following situations: the upper curve is the crushing force curve, corresponding to the above the curve is the spring with the breaking force change. The most problem this result can tell is that when the breaking force decreased, the corresponding deformation of the spring is indeed a period of horizontal, due to this damping spring, to avoid the sense of shock and reduces wear liner.
The main parameters of the gyratory crusher structure parameters and performance parameters are. Structural parameters includes the size of the discharge opening, the nip angle, crushing chamber height, dynamic cone travel, dynamic cone bottom diameter and eccentricity of the precession angle of the moving cone suspension height of the performance parameters of the number of moving cone swing, productivity (production capacity), force, weight and power as well as breaking machines. From a structural point of view, this crusher has some innovative features: the general cone crusher machine safety device and the discharge opening width adjustment device located in a fixed cone support ring safety device is a cylindrical spring, while the Cary The safety device of the bar off the crusher and the discharge opening adjustment device located on a spherical support, which use a circular spring. The annular spring is a characteristic of large damping. When the non-broken material falling into the crushing chamber, the moving cone is forced down, the spring will deformed at the presence of strong pressure.
