1、旋回式
1. Cycle type

旋回式破碎机是利用破碎锥在壳体内锥腔中的旋回运动,对物料产生挤压、劈裂和弯曲作用,粗碎各种硬度的矿石或岩石的大型破碎机械。装有破碎锥的主轴的上端支承在横梁中部的衬套内,其下端则置于轴套的偏心孔中。轴套转动时,破碎锥绕机器中心线作偏心旋回运动它的破碎动作是连续进行的,故工作效率高于颚式破碎机。到70年代初期,大型旋回破碎机每小时已能处理物料5000吨,最大给料直径可达2000毫米。
Cycle breaker is to use broken cone cone cavity cycle of movement within the shell, extrusion, splitting and bending effect for the material, coarse crushing of various hardness ore or rock large crushing machinery. The upper end of the spindle fitted with the broken cone is supported in the bushing in the middle of the beam, and the lower end is placed in the eccentric hole of the sleeve. When the shaft sleeve rotates, the crushing cone moves eccentrically around the center line of the machine and its crushing action is continuous, so the working efficiency is higher than that of the jaw crusher. By the early 1970s, large rotary crushers could handle 5,000 tons of materials per hour, with a maximum feeding diameter of 2,000 mm.

ca888亚洲城指出,旋回破碎机主要通过两种方式实现排料口的调整和过载保险:一是采用机械方式,其主轴上端有调整螺母,旋转调整螺帽,破碎锥即可下降或上升,使排料口随之变大或变小,超载时,靠切断传动皮带轮上的保险销以实现保险;第二种是采用液压方式的液压旋回破碎机,其主轴坐落在液压缸内的柱塞上,改变柱塞下的液压油体积就可以改变破碎锥的上下位置,从而改变排料口的大小。超载时,主轴向下的压力增大,迫使柱塞下的液压油进入液压传动系统中的蓄能器,使破碎锥随之下降以增大排料口,排出随物料进入破碎腔的非破碎物(铁器、木块等)以实现保险。
Crusher manufacturer is pointed out that the gyratory crusher mainly through two ways to realize the adjustment of the discharging mouth and overload safety: one is to use mechanical way, its upper spindle adjusting nut, rotating adjusting nut, cone can be broken down or up, make the discharging mouth then becomes large or small, overload, by cutting the latch on the drive pulley in order to realize the insurance; The second is using hydraulic hydraulic gyratory crusher, its main shaft is located inside the hydraulic cylinder column fortress, change the plunger of the hydraulic oil volume can change the broken cone upper and lower position, so as to change the size of the discharging mouth. Overload, the downward pressure on the spindle, the force under the plunger of the hydraulic oil into the accumulator in hydraulic transmission system, make broken cone down in order to increase the discharge port, discharge with the material into the crushing cavity of the broken material (iron, wood, etc.) in order to realize the insurance.

2、圆锥式
2. Cone type

圆锥破碎机,根据ca888亚洲城的多年出售经验来讲,圆锥破碎机主要应用于金属与非金属矿、水泥厂,砂石冶金等行业。适用中细碎普氏硬度≤5~16的各种矿石和岩石,如铁矿石、有色金属矿石、花岗岩、石灰岩、石英岩、沙岩、鹅卵石等
Cone crusher, according to the years of experience of crusher manufacturers, cone crusher is mainly used in metal and non-metal mining, cement plant, sand and stone metallurgy industries. Suitable for all kinds of ores and rocks whose hardness is no more than 5 ~ 16, such as iron ore, non-ferrous metal ore, granite, limestone, quartzite, sandstone, pebbles, etc

北京鑫众威矿ca888亚洲城认为,圆锥式破碎机的工作原理与旋回破碎机相同,但仅适用于中碎或细碎作业的破碎机械。中、细碎作业的排料粒度的均匀性一般比粗碎作业要求的高,因此,在破碎腔的下部须设置一段平行区,同时,还须加快破碎锥的旋回速度,以便物料在平行区内受到一次以上的挤压。
Beijing xinzhongwei mine crusher factory believes that the working principle of the cone crusher is the same as the rotary crusher, but only applicable to the crushing machinery of medium or fine crushing. , finely homework of the uniformity of discharging granularity, generally higher than coarse crushing requirements, therefore, at the bottom of the crushing cavity shall set up a parallel region, at the same time, still must speed up the cycle of broken cone, so that the material in the parallel zone extruded by more than once.

中细碎作业的破碎比较粗碎作业的大,故其破碎后的松散体积就有较大的增加。为防止破碎腔可能因此引起阻塞,ca888亚洲城建议在不增大排料口以保证所需的排料粒度的前提下,必须通过增大破碎锥下部的直径来增大总的排料截面。
The crushing of medium and fine crushing is larger than that of coarse crushing, so the loose volume after crushing has a greater increase. To prevent crushing cavity may cause obstruction, crusher manufacturer recommendations without increasing the discharge port in order to assure the required under the premise of discharging granularity, must by crushing the diameter of the cone bottom to increase the total discharge section.

圆锥破碎机的排料口较小,混入给料中的非破碎物更易导致事故,且因中、细碎作业对排料粒度要求严格,必须在衬板磨损后及时调整排料口,因而圆锥破碎机的保险和调整装置较之粗碎作业更为必要。
The discharging mouth of the cone crusher is lesser, mixed with feeding are more likely to lead to the broken in the accident, and because of the strict in discharging granularity, finely homework, must be timely adjust the discharging mouth after liner wear, so the insurance and the adjustment device of the cone crusher more necessary than the coarse crushing assignments.

西蒙式弹簧保险圆锥破碎机超载时,锥形壳体迫使弹簧压缩而使其自身升高,以便增大排料口,排出非破碎物。排料口的调整靠调整套来进行,转动固装着壳体的调整套即可借助其外圆上的螺纹来带动壳体上升或下降,以改变排料口的大小。液压圆锥破碎机的保险和调整方式与液压旋回破碎机的相同。
When the Simon type spring safety cone crusher is overloaded, the cone shell forces the spring to compress and raise itself, so as to increase the discharge port and discharge non-crushing materials. The adjustment of discharge port is carried out by adjusting sleeve. By rotating the adjustment sleeve fixed on the shell, the screw on the outer circle can drive the shell up or down to change the size of discharge port. The insurance and adjustment of hydraulic cone crusher are the same as that of hydraulic rotary crusher.
