Abstract: A dosing device for the continuous, gravimetric dosing of pourable material particularly rough fuels, wherein a flow of material Is conveyed from a charging opening to an emptying opening in a housing with a rotor which is driven about a vertical rotation axis, while determining the instantaneous load over a measuring section, and with a force measuring device which detects the instantaneous toad of the flow of material guided via the rotor comprising a plurality of ribs and a peripheral ring said ribs being attached to the peripheral ring, and said ribs defining a number of chambers inside the peripheral ring for carrying material during operation wherein an elastic peripheral sealing lip is arranged on the peripheral ring and engaging an upper housing wall such that an outer peripheral volume of the inside of the housing is sealed from a central volume of the housing.

Abstract: An apparatus (1) for continuous gravimetric metering of pourable material comprises a housing (2) comprising a first and a second spaced wall (5,6), a charging port (7) through the first wall (5), and a discharging port (8) through the first wall (5) displaced from the charging port (7) and a primary air port (10) with a primary outlet opening (9) through the second wall (6) opposite to the discharging port (8). In the second wall (6) a secondary air port (12) is provided with a secondary outlet opening (11) having a substantially smaller outlet area than the primary outlet opening (9) and being displaced from the primary outlet opening in opposite direction to the rotational direction of the rotor (3) and being arranged opposite to the discharging port (8), and where the primary and secondary air ports (10,12) are connected to a compressed air supply.

CPC classification number: G01G11/08

Abstract: The invention relates to a method for continuous, gravimetric metering and mass flow determination of flowable materials, comprising:



determining with a metering device an instantaneous mass flow at an anticipatory control point located a first distance ahead of a delivery point for the flowable material;
affecting discharge of the flowable material by altering a speed of rotation of the metering device and
varying the first distance of the anticipatory control point ahead of the delivery point depending on at least one of a current actual speed and a loading of the metering device, wherein the loading of the metering device is calculated on the basis of a sectoral load measurement.
