Title: Improved gyratory crusher
Inventor: WINTER HEINZ WALTER
IPC: B02C2/04
Filed: 1967-04-17
Abstract: 1,118,956. Gyratory crushers. ALLISCHALMERS MFG. CO. 17 April, 1967 [25 April, 1966], No. 17518/67. Heading B2A. To prevent damage caused by tramp iron to a gyratory crusher of the spiderless type, having an inner gyratory head 57 is adjustable relative to an outer bowl on a vertically-adjustable bearing unit mounted in a lubricant-retaining chamber 40. The lubricant system includes a pressure-relief valve system and circulates pressure lubricant through the chamber and returns it to a reservoir. The relief valve system comprises passages between the lubricant chamber and the reservoir closable by valve means 69, 35 mounted therein and actuable in response to pressure build up in the chamber 40. In operation, hydraulic lubricating fluid is pumped via a bore 45 into a chamber 43, to lubricate the bearing, and thence the lubricant goes through a tube 44 to lubricate a step bearing assembly 55. When sufficient fluid is collected in the chamber 40, the fluid lubricates bushings 70, 71, in contact with the eccentric 63. Lubricant in the chamber 68 lubricates the ring gear 64 and pinion 75. Excess lubricant leaves via a bore 78. Another hydraulic fluid is pumped via inlet 30 into a cylinder 28 to raise a piston 27, crusher post 25, step bearing 55, crusher head 57 and crushing mantle 60 into position. Overpressure in the lower part of cylinder 28 due to tramp iron is relieved conventionally by a check valve 32. Lubricant in chamber 40 may prevent the crusher head 57 falling, unless relieved by a valve 35, which permits lubricant to pass into the upper position of cylinder 28 behind the falling piston 27. The slow lower over-pressures caused by cold viscous lubricant are relieved by the pressure reliefvalve 69.

Title: Improvements in the manufacture of sulphate of ammonia
IPC: C01C1/24
Filed: 1919-07-21
Abstract: 152,766. Lessing, R. July 21, 1919. Ammonium sulphate.-The colouring-matter usually associated with crystals of ammonium sulphate is removed by agitating the latter, in a detached condition in a clear saturated solution of that salt, maintained slightly acid-if necessary by the addition of sulphuric acid-and floating off the suspended impurities. The agitation may be performed mechanically, or by blowing with air or steam, but preferably it is effected by means of the saturated ammonium-sulphate solution, which enters at a point near the bottom of the conical-shaped treatment vessel containing the crystals. The rapid stream on entering stirs up the crystals, but as the diameter of the vessel increases only the impurities remain suspended. Fig. 1 indicates a saturator A from which crystals are removed to the vessel C by means of steam lift B. A stream of filtered saturated ammonium sulphate enters by pipe d, and is regulated by valve r. The temperature of the liquor throughout the system is maintained at the same temperature as the crystals coming from the saturator by means of steam coils in the storage tank D and the filter F. The clean crystals are discharged periodically on to the drainer H; the liquor collecting in the sump G from which it is raised to tank D by means of an air lift. Au ordinary saturator may also be adapted for the process. Crystals having been deposited, the passage of ammonia is reduced or stopped. A filtered saturated solution of sulphate of ammonia is supplied near the bottom of the saturator, and flows straight through a launder and passes to the filter as previously described.
