A method and mechanism for dewatering fine coal or the like by a filtering operation including a horizontally disposed cylindrical housing defining a pressure chamber within, an intermittently movable filter belt wrapping support rolls for the belt at each end with the rolls having driving and braking devices, movable sealing devices positioned at openings to the chamber to seal the belt where it extends into and out of the chamber, a support for the belt with means for draining filtrate dewatered from the coal, and means to apply pressure to the chamber above the belt for dewatering the coal and for providing pressure beneath the support for the belt to balance forces within the housing.

Pressure/belt filter, particularly for dewatering fine coal

A wet settling machine for processing mineral mixtures, particularly fine-grained coal and other minerals, has the separating liquid energized into a pulsating motion with a basic wave and an upper harmonic superimposed on the base wave. The harmonic wave may proceed longitudinally with respect to the base wave or transversely with respect to the base wave. The base wave is pneumatically generated and the harmonic wave is mechanically generated.

Operating method and settling machine for processing coal

An apparatus is disclosed for the conveyance and/or treatment of material-laden hot gases in a furnace for the calcination and sintering of lime, magnesite, dolomite or the like. The apparatus is utilized as a ventilator or ventilator mill in the furnace and is cooled by means of a cooling liquid circulating in a closed cooling circuit. Channels are provided in the ventilating apparatus for the liquid coolant and particularly such channels are provided in portions of the apparatus such as blades which are subject to the greatest heat stresses.

Apparatus for the conveyance and/or treatment of hot gases

A mechanism and method for preheating a coarse fraction and a more fine limestone fraction in a shaft preheater including a first central vertical inlet for receiving the coarse fraction which forms a descending core in a vertical preheating chamber, and a second vertical inlet receiving the finer fraction annularly around the core, directing a first upper gas feed radially into the fractions with the gas first penetrating the outer finer fraction and then the inner fraction, and directing a second heating gas flow at a lower level into the core to bring the core up to the temperature of the outer layer, with the gases being received from a rotary kiln, and mixing the fractions and directing them to the rotary kiln from the lower end of the preheating chamber.
