An assembly for transferring solid particulate matter has a pressurized vessel for retaining a pre-determined quantity of the solid material. A transfer conduit connected to the vessel carries the solid material to a loading vessel, be it a processing tank, a storage vessel, or any other similar container. A discharge nozzle carried by a distant end of the transfer conduit is connected to a vacuum source, whereby a slight vacuum is created at the discharge opening. A separate dust removal conduit is secured immediately adjacent to the discharge nozzle for removal of the dust particles away from the discharge nozzle. The dust particles are collected in a separate vessel, which is mounted in a flow of air from the dust collection conduit and an exhaust fan. Mesh sleeves suspended in the vessel, capturing the dust particles on exterior surface thereof. Periodically, the dust particles are dislodged from the sleeves by blowing air through the sleeves. The dislodged dust particles are collected for disposal or recycling.
