An apparatus for dispensing measured quantities of particulate material includes a tubular duct arranged so that an air stream in the duct carries material along the duct and a row of hoppers each for containing the material to be dispensed; the hoppers being connected to the duct so that material can be dispensed from the hopper to the duct. A separator container is provided in the duct such that the material in the duct carried by the air flow passes to the separator container. A centrifugal separator section is provided in the container for separating the material from the air flow to deposit the material into the container while the air flow is discharged from the container. The container is mounted on legs with load cells for weighing the deposited material while the material is maintained in the separator container and the air lock valve are controlled so as to continue to discharge the material up to a predetermined weight and to halt the discharge when the predetermined weight is reached.
