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

Provided is a pallet car for the transport of bulk material for a thermal treatment thereof. The pallet car comprises a frame with at least two opposed cross-beams on which grate bars rest and two end pieces each connecting the cross-beams with each other, which each include at least two rollers and at least one side wall. In the pallet car, the grate bars and/or the side walls and/or the insulating plates are made of a ceramic fiber composite, wherein the fibers are metallic and high-temperature resistant.

Pallet car for the transport of bulk material for a thermal treatment

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.
