Description

Patented Dec. 23, 1924.
HNITED STATES PATENT OFFICE,
CRUSHIN'G MILL.
Application filed June 9,
To all whom it may concern.
Be it known that I, EMIL BnirrHnLMEss, a citizen of the German Republic, of Dusseldorf-()berkassel, Germany, have invented certain Improvements in Crushing Mills, of which the following is a specification.
This invention relates to a crushing-mill of the ring-and-roller type, and its object is so to construct the mill that the crushing mechanism can be assembled outside the casing and treated, in respect of its application to and removal from the casing, as a separate, complete structure. Vith this object in view, the invention consists in the provision of a casing fitted with a detachable hood and slotted side walls into which the bearings of the roller shafts can be slid radially together with all the assembled elements of the crushing-mechanism.
Figs. 1 and 2 of the accompanying drawings represent elevations at right angles of the complete apparatus,
Figs. 3 and 4;, elevations at right angles of the assembled crushing-mechanism, and
Figs. 5 and 6, corresponding views of the casing without the hood.
The crushing-mechanism of the mill comprises a crushing-ring 0 and three crushingrollers (Z. The latter work against the inside of the ring, rotation being imparted to the crushing-elements by means of the shaft 6 of one of the rollers which is arranged centrally above the other rollers. A driving pulley 2' is secured to the shaft e. Bearings m are mounted on the shaft 0 and bear ings n are mounted on the shafts 0 of the lower rollers. Buffer springs h are arranged between adjacent bearings so as to force the rollers d resiliently against the crushingring. All these elements can be assembled, as shown in Figs. 3 and 4t, and introduced into the milling-casing a as a separate, complete structure. The casing is divided on level with the driving shaft 6, the upper, hood-part 5 being detachable to admit the crushing-mechanism. Semi-circular notches (I in the side walls of the hood and casing 1924. Serial No. 718,994.
accommodate the shaft 6, and the side walls of the casing have open-ended slots p through which the shafts 0 are admitted in a transverse direction. The bearings m are fitted with brackets 1 whereby they are supported on shoulders 8 formed on the reinforcement ribs of the casing, and hooked lugs t on the brackets 0, drop into engage ment with screw-bolts f whereby the entire crushing-mechanism can be firmly secured in position. All that is required for the removal of the crushing-mechanism from the casing, therefore, is the detachment of the hood I) and a loosening of the screws f.
Vertical slides Z (Fig. 1) may be used for covering the slots 79 after the introduction of the mechanism. The feed chute Z: of the mill is connected to the casing a. so as to leave a free passage for the admittance and the removal of the crushing-mechanism.
I claim 1. In a crushing-mill, the combination with a cruslung-mechanism comprising a crushing-ring, crushing-rollers fitted on shafts and arranged inside said ring, bearings mounted on the roller shafts, and buffer springs abutting against adjacent bearings so as to force the rollers against the rings, of a casing which is slotted so as to admit said crushing-mechanism transversely of the roller shafts as a complete, assembled structure.
2. In a crushing-mill. the combination with a crushing-mechanism comprising a crushing-ring, crushing-rollers fitted on shafts and arranged inside said ring, bearings mounted on the roller shafts, and buffer springs abutting against adjacent bearings so as to force the rollers against the ring, of a casing which is slotted so as to admit said crushing-mechanism transversely of the roller shafts as a complete. assembled structure, and means for securing the crushingmechanism in position through the medium of the bearings of one of the roller shafts.
