Title: Reject spouts for centrifugal extraction apparatus
IPC: B02C13/18
Filed: 1965-05-19
Abstract: 1,034,90. Centrifugal classifiers. MICROCYCLOMAT CO. May 19, 1965 [June 1,1964], No. 21245/65. Heading B2P. In a pulverizer-pneumatic classifier apparatus for treating solid materials, coarser and denser materials thrown out by centrifugal force against the wall 36 of the classifier section of the apparatus are discharged through reject spouts 51 spaced about the classifier wall and each comprising a hollow housing having at one end a discharge conduit 59 and secured at the opposite end over a discharge opening 52 in the classifier wall by means of a plate 53 having a corresponding opening therein. A vertical deflector plate 60 is disposed in the opening 52 so as to deflect the air-borne stream of material, travelling within the wall 36, away from the opening 52 thereby increasing the retention time of the material in the classifier section and preventing entrainment of the finer and lighter materials with the coarser and denser materials through the opening 52. The plate 60 may be fixedly mounted or may be hinged as shown at 61 and its angular position relative to the wall 36 adjusted by a screw assembly 63-65 on which a graduated scale may be mounted. In a modification, Figs. 4-6 (not shown), the reject spout 51A has a sleeve 66 provided adjacent the intersection of its side wall 51A with the receiving plate 53A. A shaft 68 is fitted in the sleeve for limited rotation therein. A deflector plate 60A is inserted through opposed slots 67 in the sleeve and a slot 69 in the shaft 68. A knob 71 when tightened on a threaded portion 70 of the shaft 68 causes the position of the plate 60A to become fixed. Loosening of the knob permits angular adjustment of the plate by rotating the shaft 68. A graduated scale 72 on the shaft cooperates with a fixed pointer 73 on the end of the sleeve 66 to give the exact position of the blade 60A. Alternatively, the deflector plate may be mounted in the position indicated by dotted lines so as to deflect the coarser or denser particles moving along the inner surface of the housing wall 36 into the reject spout. Solid material introduced in the lower casing 10 of the apparatus is reduced in size and de -agglomerated by rotor blades 32 and air attrition between the particles. The reduced material is then carried in an upward current of air induced by a fan 46-48 into the classifier section 36 where the finer and lighter materials pass between finger-like blades or rods 42 carried by the rotor and is drawn automatically through a passage 50 between a diaphragm ring 44 and the carrier plate 40 into an annular space 45 where they are caught by the fan blades 48 and discharged. The discharge conduit 59 from each reject spout may be fitted with a resilient flapper extraction valve or may be connected to a bleeder cyclone-type separator.

Title: Process for manufacture of magnesium compounds
IPC: C01F5/24
Filed: 1946-07-22
Abstract: In a process for the manufacture of relatively pure magnesium compounds from brines, e.g. sea water, containing convertible magnesium salts, impure brine is reacted with a lime-containing material to form magnesium hydroxide, which is removed as a slurry from the mother liquor, the slurry being precarbonated to a degree sufficient to convert the dissolved calcium salts to solid phase calcium carbonate and further carbonated to form magnesium bicarbonate in solution, the latter being <PICT:0629262/III/1> removed and converted, e.g. by aeration, to solid magnesium carbonate which is then separated from the effluent.  According to Fig. 1, sea water, which may be pre-treated, e.g. by chlorinating and settling out readily-removable solids, is supplied to a precipitating operation 10 wherein brine is reacted with a precipitant such as lime or calcined dolomite from 11 and 12, in the form of a slurry or powder, the resulting precipitate of magnesium hydroxide being allowed to settle in tank 10b, from which dilute slurry is withdrawn and thickened at 13.  In order to remove dissolved calcium salts the slurry from 13 is precarbonated at 70 DEG  to 90 DEG  C. either by passing hot flue gases therethrough or by mixing with bicarbonate solution from line 14.  The slurry is then diluted at 16 with effluent 14 and carbonated at 17, insoluble impurities being separated as a sludge at 18 leaving an effluent from which neutral magnesium carbonate is precipitated by aeration at 19 by a neutral gas, e.g. air.  After settling at 20 and de-watering and washing at 21, the magnesium carbonate may be further treated to produce other magnesium compounds, e.g. it may be calcined to form magnesium oxide or it may be dried and expanded at 25 to produce basic magnesium carbonate.  While a major part of the effluent from the settling operation 20 is shown being returned to the dilution step 16, a minor part is bled off from the system at 22 to maintain the desired salt concentration. Other optional features include: returning a portion of the settled solids from 20 to the aerating step 19 (Specification 580,367), adding a coagulant, e.g. boiled starch, to the precipitant, and using a sintered precipitant (Specification 557,845). Specifications 467,543 and 554,760 also are referred to.
