Referring to the form of FIGURES l and 2, the material to be crushed is fed from above by an inlet spout 40 which, in FIGURES l and 2, is shown as a tubular curved elbow having an upper inlet 41, generally coaxial with the Crusher head,Jaw Crusher Manufacturer In India and an outlet aperture 42, which, under some circumstances, as shown in the figures, may be located radially a substantial distance from the axis of the head. It may, for example, miss the extension cap 33 altogether. As will be below described, suitable means are employed for rotating the member 40 at a suiiicient speed to impart centrifugal movement to the material fed downwardly and outwardly therethrough.

It will be understood that the crushing head of the cone Crusher is not rotated but only gyrates, and any rotation that it has is caused by a slight frictional drag with the bowl liner during operation. Segregation of feed takes place which results in non-uniform crushing around the crushing cavity. It has been customary in the past to use a feeding plate at the top of the crushing head, but, in practice, it is advantageous to avoid the use of a feeding plate in order to distribute feed and to employ an entirely separate feeding mechanism.Grinding Mill In Zimbabwe. Thus the feed member 40 is provided with an outlet 42 which is radially exterior to and completely clears the extension cap 33, and itself constitutes the sole means for feeding material outwardly and downwardly toward the crushing cavity 22 or 22a. Actually, the liner and mantle shown in FIG- URE 1 are such as will define the lower crushing cavity 22, and a modification of the form of bowl liner and mantle would be necessary in order to define a crushing cavity including the upper portion 22a. The showing will therefore be taken as diagrammatic.

As shown in FIGURE l, we provide suitable supporting bolts 48 or the like which support a cross or top platform 50, which, in turn, supports the upper part of the feed distributor generally indicated at 52. This distributor is suspended or extends downwardly from the top plate or platform 50 and is employed to discharge or distribute material in a generally horizontal direction or plane at a point within the feed cone 34, or its upper wall portion 34a. The material to be crushed is initially fed downwardly through an upper passage which may have an upper flange 54 and which may, if desirable, be removable and replaceable. The distributor and its support are shown in detail in FIGURE 2 and may include an upper ange 55 bolted or otherwise connected to the top plate 50a. A depending sleeve 56 integral with or connected to the flange 55 forms the inner frame or foundation of the distributor.
