Abstract: Ore pellets of homogeneous composition and loose consistency, free of pellet germs and having a reduced content of adhesive, are formed by dry mixing ore powder of particle size less than 90 microns (preferably about 65% less than 40 microns), with a moisture content of less than 0.1%, and powdered adhesive, e.g. bentonite, 0.05 to 1 percent by volume preferably added over a period of at least 11/2 minutes; then adding to the dry mix 8 to 9% of water at 50.degree. to 90.degree. C., and then homogenizing by a plowing action by which the mass is torn and whipped apart without being allowed to perform a strong rolling action, preferably for only 50 to 90 seconds at a temperature of 60.degree. to 70.degree., rubbing under pressure also being avoided, after which the mixture is formed into pellets with addition of 0.4 to 0.5% of water during the forming process. The formed pellets may be roasted, baked or sintered.

Abstract: A method and apparatus for the production of coke from coal by a dry distillation operation wherein the coking plant is provided with a computer unit that receives signals from the coal leveling mechanism, the door mechanism, the quenching car mechanism, and a signal value for the time required to achieve the coking of the coal. The computer prevents the opening of any given coking chamber until the minimum coking time has lapsed and the opening of the chamber and discharging and quenching of the coke is correlated to the actual operating conditions rushing at that time. If desired, the charging and emptying operations may be carried out on a completely automatic basis.
