1 Claim. (01. 83-9) This invention relates to crushing mills and quired to pass an excessively large uncrushable has for its principal object the provision of particle. ring-roll crushers of economical and efficient de- The shaft ill besides acting as a, pivot for sign and of simple and rugged construction which are useful for crushing or grinding a wide variety of materials, the construction and operation of which, together with further objects and advantages, maybe best understood from a consideration of the following descriptiongiven in material and accordingly reduces the power rethe arms 9 operates as a drive shaft and to this end is provided with a series of sprockets l3, l4, and I5, operatively connecting the roll and the drum with a motor [6 so that both the roll and drum may be driven positively. The sprocket [3 by means of a chain l'l drives a sprocket i8 be duplicated at the other side of the drum to connection with the accompanying drawing keyed 0 & p gear 19 mounted O a S aft 0 wherein: I journaled in suitable supports 2i. The spur gear Figure I is a plan view illustrating one eml9 meshes with a second spur gear 22 and is bodiment of the invention; mounted on the rollershaft 5, and the spur gear Figure II is a side elevation, and 22 in turn meshes with a ring gear 23 aflixed Figure III is an end elevation in vertical secto the periphery of t e d111m- The Sprocket 15 tion of the embodiment illustrated in Figure I. ,thrll a chain 24, drives p c et 5 mounted Referring now particularly to the embodiment Oh roll trunnion ehdthe p et I4 is illustrated in Figures I, n, and 111, it will be ive u a chain 26 y means of a sprocket seen that the principal elements of the invenkeyed t a r c n ear mechanism 28 built tion comprise a roll I disposed within and adaptin the motel The Shaft 18 Supported by 20 ed to roll on the lowermost inner periphery of and jellrneled in the Supports 29 Whieh in tu n,
a rotatable hollow cylinder or drum 2 which is er With the supports [6 and 20, are mountmounted with its axis of rotation in a horizontal ed 011 the f ame 1. position. These two elements provide opposed Will be Seen that this Provides a u ita y crushing surfaces defined by the juxtaposed surstructure in which the Several parts a e, simply 25 faces of th 11 d t d and ruggedly associated and yet freely acces- The drum is rotatably supported in a horisible for u purposes as y be quired. zontal position by the horizontal rollers 3, which Moreover, mounting of the drum on external engage annular tracks 4 provided on the outer lellelsrwhile Providing a Suitably ug ed mount- 30 periphery and near the edges of the drum. The e r t drum. admits of removing e drum so mners 3 r mo ted n h ft 5 whi are and the roll as a unit after disconnecting the journaled in suitably rugged supports 6, which arms 9 and the Chain are in turn mounted on a suitable frame 1.. AS Previously indicated, the material to be This provides a simple and rugged construction crushed is fed into e horn angle between the capable of Sustaining heavy loads and yet roll and the inner periphery of the drum. This 35 vides for ready assembly or disassembly as des effected by the chute Projecting into the sired and easy access for inspection, cleaning, horn angle from the hopper 3L The C u e is and repair. preferably trough-shaped and open at the to The r011 is provided with axial trunnions but may, if desired,beentirely enclosed and prefi0 8, j'ournaled in the arms or links 9, adapted to era'bly 13 so constructed as to deposlt the pivot on the haft These arms are terial at or near the center of the drum so that vided with suitable journals II and I2 to prothe material deposited m horn angle W111 vide bearings for the trunnions 8 and the shaft Spread evenly over crushing surface The In. Thisarrangement provides a means for rehopPer is mounted on the support 32 .amxed to straining the roll against rocking back and forth the Journal box H of the arm a this manner on the inner surface of the drum, and yet allows advantage is taken t vibration of the the roll to rise and fall as may be required to paratus and the vert cal movement of the roll I during crushing to facilitate the feed of material pass uncrushable particles from the hopper and to minimize arching and m Preferably, the arm is disposed .at an angle jamming therein. so that its point of pivot, the shaft I0, is below As illustrated in Figure III, a discharge chute the horizontal Pl of the trunnions .This 37 is provided adapted to discharge material to Shifts the effective component t e crushing a suitable conveyor or screen. While the chute force pplied by the roll toward the incoming is shown at one side of the drum only, it may accommodate discharge of the crushed material from both sides or the drum may be partially closed on the side opposite the hopper so that dischargeoi the material is directed to one side 01' the drum only. 7
It will be understood'that the principles of the invention may be embodied in many different forms of which theembodiments illustratedand adapted to roll on the inner surface thereof and adjacent the lower-most portion thereof, means for maintaining the axis of said roll parallel with the axis of said drum, said means comprising parallel arms Journaied to the axial extremities of said roll and to points external of said drum located substantially in the common tangent plane oi! said drum and said roll, the plane of said arms being inclined to said common tangent plane, at an angleless than 45 degrees, a hopper support mounted on one of said arms above the axial extremity of said roll,'a hopper mounted on said support and arranged exteriorly of said drum and having a chute projecting into the horn angle formed between said drum and laid roll which is most remote from said external points whereby the roll, hopper and chute move as a unit about said external points.
