摘要： A vertical shaft impact crusher is provided com­prising a housing (14), a rotor (24) mounted within the housing for rotation about a vertical axis and propell­ing incoming rock outwardly against a crusher ring (70), wherein the crusher ring is comprised of segments (289) each capable of autogenous, impact or semi-­autogenous crushing or combinations thereof in order to precisely control the size and shape of crushed prod­ucts.

摘要： A conical crusher having a rigidly supported outer frustoconically shaped crushing member (18) and an inner conical crushing member (20) supported on a wobble mechanism (32, 34, 38) which is in turn supported by air bellows (58). The air pressure in the air bellows is regulated to adjust the spacing between the inner and outer crushing members, and therefore the particle size of the crushed material. The inner and outer crushing members are readily replaceable.

摘要： A method of conical crushing to achieve the grinding of feed material includes narrowing the crusher setting beyond the specified minimum limit to enable the head (20) to periodically exert high levels of compressive crushing force, interspersed with low pressure relief periods for mixing of the particles (70), the cycle of crushing periods corresponding with the gyrational cycle of the head (20). The method also includes increasing the releasing force exerted upon the crusher bowl (26) to promote the grinding action of the crusher at its narrowed setting.

摘要： A crusher head (108) wobbles due to rotation of an eccentric (182) within a corresponding bore of the crusher head. Material, such as rocks, to be crushed enters by gravity in a crushing gap (102) between the crusher head and a crusher stator (124), whereafter the crushed material exits through the lower end (110) of the crushing gap (102).
An anti-spin mechanism preventing spinning of the crusher head (108) includes fingers (130, 134) disposed at a bottom portion of the crushing gap (102). The fingers alternate with free openings for exit of the material.
The anti-spin mechanism does not interfere with the crushing apparatus as do clutch-based, anti-spin mechanisms. The anti-spin mechanism relies on mechanical prohibition of rotation of the crusher head (108) with respect to the bowl (124) due to finger-on-finger engagement. The fingers can be mounted on mantles (62), bowl liners (66), bowls (72), housing, or crushing heads (63) to achieve anti-spin functions.

摘要翻译： 破碎机头（108）由于偏心轮（182）在破碎机头部的对应孔内的旋转而摆动。 要粉碎的材料，例如岩石，通过重力在破碎机头和破碎机定子（124）之间的破碎间隙（102）中进入，然后破碎的材料通过破碎间隙（102）的下端（110）离开， 。 防止破碎头（108）旋转的防旋转机构包括设置在破碎间隙（102）的底部的指状物（130,134）。 手指与自由开口交替排出材料。 防旋转机构不会像离心式，抗自旋机制那样干扰破碎装置。 防旋转机构依赖于机械禁止由于手指接合而使破碎机头（108）相对于碗（124）旋转。 手指可以安装在外壳（62），碗衬（66），碗（72），外壳或破碎头（63）上以实现抗自旋功能。

摘要： A conical gyratory mill (10) for regrinding, milling or fine pulverization of materials, having a milling media (74), such as milling balls, located in a milling space (72) between a milling bowl (18) and milling head (20). The material to be milled is introduced into the top of the milling space and is milled as it descends through the milling space by interaction with the milling balls, milling bowl and head. A fluid is introduced at the bottom of the milling space and is discharged at the top of the milling space, carrying with it material which has been milled to the desired degree of fineness.
Useful for providing a reduced energy consumption, a simpler construction, an easier maintenance and a more uniform production.

摘要： A method and apparatus of comminuting ore-like ma­terial to produce a disproportionately large volume of flakier product which is easily and more efficiently ground in a mill, wherein the method includes the appli­cation of a stream of liquid all around the inlet of a conical crusher (120), increasing the speed and reducing the throw of the crusher to produce a generally flaky product, crushing the ore in the presence of the liquid and passing the ore and liquid slurry directly to a grin­ding mill (114).
