A method for cleaning of a roller screen transporting and screening particles by means of at least three rotating rollers. The rollers are installed in succession at given clearances and arranged transversally in relation to the transport direction of the particles to screen a desired range of particle sizes. At least one roller changes its circumferential velocity and/or its rotational direction over time at defined time intervals for defined time periods such that for this defined time period for at least one pair of neighbored rollers one roller has a higher circumferential velocity than the other and/or both rollers roll in opposite rotational directions.

Self-cleaning roller screen

A method and its related plant for the thermal treatment of iron containing oxide, in which fine-grained solids are heated in a preheating calcining stage and exposed to a reduction gas in a subsequent reduction stage. Off-gas from the reduction stage is guided through a separation device wherein water originating from the reduction stage is separated. The water separated in the separation device is recycled into a water treatment section, from which the recycled water is supplied to a water electrolysis plant and/or a steam reforming plant producing hydrogen, and the produced hydrogen is supplied to the reduction stage as reductant and/or to the preheating calcining stage as fuel and/or to the gas heater as fuel and/or from which the recycled water is supplied to the separation device.

Plant and method for the thermal treatment of solids

A method for charging pallet cars of a traveling grate for the thermal treatment of bulk material includes in a first step a first layer is applied as a hearth layer on a grate surface of the pallet car. In at least one second step a second layer at the same time or successively is applied as a side layer on two opposed side walls of the pallet car and a third layer is applied as green pellet layer between the side layers and on the hearth layer. The pellets used for the grate and the side layer differ in terms of their diameter and size distribution.
