Gyratory crusher greatly improves operational reliability

The gyratory crusher upper jib bearings are in the form of spherical bearings, which evenly absorb the loads in all directions, eliminating the consumable parts of the upper jib bushing of the traditional gyratory crusher, greatly improving the operational reliability and significantly reducing operating costs. In addition, because the spindle can do a variety of movements, the boom bearing oil seal needs to be adapted, so the oil seal must be special. The gyratory crusher is equipped with a double special long tongue seal and a specially shaped scraper. This special scraper removes dust and dirt from the spindle bush. The spindle is an integral forged part, the spindle bushing can be replaced, and the spindle is not threaded. Jaw crusher manufacturers eliminate the fatigue failure of traditional threaded spindles. At the same time, the metallic contact surface between the upper region of the movable cone and the main shaft can disperse the impact force generated when breaking the large gravel.

The above ore crushing process is a three-stage, one-closed process. The open pit ore is transported from a motor vehicle to a beneficiation plant and directly discharged into a PX1200/180 gyratory crusher ore. The size of the ore is 1000 mm, and the designed production capacity is 606 tons / hour, the size of the discharge port 180 mm, product size 350 ~ 0 mm. The coarse crusher ore is fed into 2 PYB-2200 standard cone crushers by the 1250 chain feeder. The size of the crusher in the crusher is 30 mm, and the product size is 75 to 0 mm. After being crushed, an intermediate storage tank with a volume of 125 cubic meters is provided. Finely divided into 4 sets of PYD-2200 short head type cone crusher, discharge mouth size 8 mm, product size 25 ~ 0 mm. Before the crushing, there are 4 szz type 1500×3000 mm self-centering vibrating screens for pre-screening. The screen size is 14 mm. There are 7 other sieves of the same type as the sieve after the fine crushing.
