Compound Spring Cone Crusher for Rock Ore Mineral

The compound spring cone crusher as one rock 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 a 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. The Compound Spring Cone Crusher is suitable for crushing various ore and rock in mining industry such as iron ore, non-ferrous metal ore, basalt, granite, limestone, quartzite, sand stone, pebbles, etc.
