Granular mixing equipment

Imperial Chemical Industries Ltd, BelgF 636956(1964) CA 62, 7580-81 (1965) [A Blasting Explosive was prepd by mixing for 15 mins 88 parts granular AN 12 ps of a 50% aq AN soln in a rotary blender equipped with paddles. The resulting mass was spread on sheets and dried at 45° for 14 hrs. The crystal cake was crushed, forced to pass a sieve (BS No 6) and then mixed with 9 parts of fuel oil for each lOOps of sieved material]... 

In a 1 litre three-necked flask, equipped with a thermometer, glycerine-sealed mechanical stirrer (compare Fig. II, 7, 10) and calcium chloride (or cotton wool) guard tube, introduce successively 700 g. (380 ml.) of concentrated sulphuric acid, 100 g. (63 ml.) of oleum (20 per cent. SO3), 90 g. (81 -6 ml.) of chlorobenzene and 68 g. of chloral hydrate. Stir the mixture rapidly enough to keep the materials well mixed for 1 hour during this period the temperature rises to about 50° and some granular... 

TS and TOC were analyzed with a HORIBA EMI A model CS500 analyzer equipped with a resistance furnace and an ND-IR detector. For TS, about 0.2 g of sample, mixed with 1 g of granular tin, was combusted at 1350°C in the analyzer. For TOC analysis, about 0.1 g of sediment was fumed with HCl to remove carbonates. The decarbonated samples were combusted at 1350°C in the analyzer. The precision for TS and TOC analyses is better than 5%.
