Abstract: A method for conveying material wherein a conveyor belt is guided over head drums so as to form a forward traveling and returning stretch. The conveyor belt is guided in such a way that the forward traveling and returning stretches intersect each other as seen in the horizontal projection, i.e., as seen in the direction of the drum axes, and the conveyor belt travels over both head drums from the top toward the bottom.

Abstract: According to the invention, the loose coal is displaced from the peaks to the valleys of the waves on the narrow, long coal cake and is beaten down on the coal cake. The inventive device comprises at least one scraper (12) and at least one vertically movable impact plate (13) that are disposed one behind another and are fitted with a connection (7) to a holder. Furthermore, means are provided for generating a relative movement between the scraper (12) and the impact plate (13) and between the scraper (12) and a stamping form. The scraper (12) and the impact plate (13) are interconnected by means of a device frame (14) so as to form a structural unit (6) that is connected to the holder. Preferably, the structural unit (6) can be moved along the stamping form and is equipped with a drive unit. For this purpose, the holder encompasses a guide that extends along the stamping form as well as a carriage or a car which can be slid or moved on said guide and to which the unit (6) is connected with the aid of a boom.

Abstract: The invention rates to a method and apparatus for producing a coal cake for coking, in which a bed (3) of coal is compacted in a mould (2) by pulses of hammers (19) which act on the bed, and is solidified to form a block. In accordance with the invention the bed (3) is not only worked on in pulses by the hammers (19) but is also subjected to compression.
