A method determines the bulk density of bulk material (2) in a mobile crusher, in which the bulk material volume of bulk material (2) delivered onto a conveyor belt (1) is determined. The method is configured such that the bulk material weight can be determined reliably over a relatively prolonged operating period of a mobile crusher, even with varying bulk material density. Both the bulk material volume and the bulk material weight of a conveyor belt section (3) are sensed in successive time steps, and the bulk density is determined from the quotient of the bulk material weight and the bulk material volume.

The present invention relates to a method for characterizing a coating, in which method a mass and/or a volume of a basic body is/are measured prior to coating; a mass and a volume of the basic body with the applied coating are measured; for characterizing the coating, a density of the coating is determined from the volume and mass measurements; wherein the volume is optically measured.

A device for measuring powder bed density (PBD) (powder density for a layer) in additive manufacturing (AM) during operation. The device comprises means for determining a mass of the powder and means for determining a volume of the powder during spreading, thereby allowing determination of the powder bed density (powder density for the layer). The means for determining a volume of the powder comprises a laser assembly adapted to move a laser across a powder layer surface in both left and right directions for scanning. The device further allows for the determination of the layer surface profile as well as static and dynamic powder characteristics of the processes involved in the AM operation.
