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.

Disclosed is a monitoring system for a conveyor belt weighing system, the monitoring system comprising: a status page displaying a plurality of calibration status displays for the conveyor belt weighting system, each of the calibration status displays including a reference calibration value and a comparison between the reference calibration value and a calibration value for the conveyor belt weighing system, wherein the reference calibration value is an ideal value for the calibration value.

An article sorting apparatus includes: a conveyance path extending in a first conveyance direction; at least one conveyance unit including a belt that forms a load surface on which an article is placed and a driving portion to drive the belt, and configured to move along the conveyance path and to convey the article placed on the load surface in a second conveyance direction that intersects the first conveyance direction; a loading portion configured to load the article onto the load surface; a sorting portion configured to sort the article received from the at least one conveyance unit; a weight information detector configured to detect weight information correlated with weight of the article transferred to the load surface; and a controller configured to control driving the driving portion in accordance with the detected weight information, to transfer the article placed on the load surface to the sorting portion.

A conveyor system comprising a conveyor and a conveyor weighing apparatus. The conveyor weighing apparatus has a load determination device for determining the load exerted the conveyor on a conveyor support. The conveyor weighing apparatus may have measurement devices for measuring the angle and speed of the conveyor. The load determination device determines the load exerted by the at least section of conveyor in both laden and unladen states, and the results are combined with the speed and angle measurements, and with known system constants, to calculate the weight of material being conveyed.

Method for weighing an object transported on a mover of an electromagnetic conveyor and electromagnetic conveyor. Method includes lifting object off the mover with a lifting device; setting down object onto at least one transport plane of a weighing station arranged at a weighing region of the track and arranged on at least one weigh cell. The transport plane extends in the direction of movement to support the object when in the weighing station. The method also includes actively driving object while lifted off from the mover and while supported on the transport plane with the mover as it moves along the track through a weighing region; weighing object with at least one weigh cell while the object is supported by the transport plane; and setting down object on the mover after weighing in the weighing station for onward movement of object along the track with the mover.
