The 520,000 tonne/year ethylene plant that Maruzen Petrochemical shut down after the earthquake restarted on April 4. The company's 115,000 tonne/year ethylene glycol plant in Chiba Prefecture was restarted on April 10, and the current operation of the plant is basically the same. Smooth, the starting load of the equipment is gradually increasing.
The spring cone crusher has a perfect combination of high-performance crushing chamber and high crushing frequency, which greatly improves the crushing capacity. At the same time, it also absorbs the principle of laminated crushing, which to a certain extent reduces needle like materials. The spring safety system is an overload protection device that provides "spring type" over iron release protection for foreign objects (iron blocks). Under normal use, the equipment has a fault free operation rate of over 95%.
Operational Principle:
The spring cone crusher uses a working surface between a movable cone and a stationary cone to crush ore. The moving cone is supported on a spherical bearing and fixed on a suspended vertical axis, which is placed inside an eccentric sleeve, which in turn is placed on a thrust bearing. The moving cone and the vertical shaft are driven by an eccentric shaft sleeve, which is driven by a horizontal shaft and a belt pulley, and transmitted through an bevel gear. The pulley is driven by an electric motor through a V-belt. The lower part of the vertical axis is installed into the eccentric sleeve, and when the eccentric sleeve rotates, a conical surface is drawn with the axis. Therefore, when the moving cone approaches the stationary cone, the ore is crushed. The casing consists of two parts, upper and lower, connected by bolts. A strong spring is installed on the bolt to prevent damage to the crusher (such as the spindle) when metal or other hard objects fall into the crushing chamber. If a metal block or other hard object (nut, drill head, etc.) enters the crushing chamber together with the ore, the stationary cone is lifted and the ore discharge port increases to discharge it.
