Title: Improvements in or relating to grinding mills
IPC: B02C4/22
Filed: 1926-09-08
Abstract: 261,322. Ehrhardt, J. Sept. 8, 1926. Roller - and - breast mills; hollow cylinder and internal guided roller. - In a finegrinding mill for treating graphite, colouring-substances, chalk, &c. in which the pasty material is fed by pressure through the fixed grinding-stone, a central rotary grinding disc or wheel is used in conjunction with a number of fixed grinding-blocks which are arranged in more or less radial formation and pressed automatically against the circumference of the rotary disc by means of counterweighted levers. As shown, Figs. 1.2, and 4, the guiding-wheel 5 is carried at the upper end of a shaft 2 housed within a standard 1 carrying a casing 6 having a number of projecting tubular members 8 and surmounted by a pan 9 into which the pasty material to be treated is fed by a pipe 11. The tubes 8 and the axiallyadjustable grinding-blocks 12 therein are arranged so that their axes are somewhat oblique to the radius of the wheel 5. Each block 12 is screwed upon the head 28<1> of a hollow shaft 28 which is screwed at the outer end for the reception of a screw cap 29 to which the mouthpiece 30 of a flexible supply pipe 10 is fixed. The enlarged head of a casing 20 surrounding the shaft 28 is pressed against the block 12 by a sleeve 26 held in position by a nut 27. A screwed sleeve 21 surrounding the sleeve 26 engages the threaded rear end of the casing 20, and is fitted at its end with a ratchet wheel 22 and a lever 23 provided with a counterweight 24. When the lever 23 drops, due to the wear of the block 12, a spring- pressed latch 25 thereon engages the teeth of the wheel 22 and rotates the wheel 22 and sleeve 21, thereby maintaining the block at a constantly uniform pressure against the wheel 5. A feather 19 is inserted in the casing 8 by means of an auxiliary sleeve 8<1> and engages in a longitudinal slot in the casing 20. The inlet channels 18 open as close as possible to the front edges of the grinding-blocks 12, and have slot-shaped openings lying parallel to the axis of the wheel 5. The material in the vessel 9 is conveyed by air pressure in the pipe 11 to the flexible pipes 10 connected to the mouthpieces 30. The shaft 2 runs in bearings 4 and at its lower end has a splined connection with a worm 15 held against endwise displacement. The worm 15 drives a wheel 14 on a cross-spindle in the bearing-box 13, and an eccentric on the spindle operates a pivoted rocking-arm 16 which supports the shaft 2 at its lower end and imparts endwise movement thereto. The grinding-wheel may be mounted on an horizontal axis.
