Abstract: A truck dumper including a material receiving hopper, a tilt table configured to dump a load from the truck or truck trailer into the material receiving hopper. The invention includes a stilling shed positioned above the material receiving hopper and at least one curtain baffle suspended below the roof of the stilling shed. The curtain baffles are positioned such that there is a gap located near the roof and an upper margin of the at least one curtain baffle through which air can flow. The invention further includes an air exhaust structure configured to exhaust dust laden air from the interior of the stilling shed.

Abstract: A method and apparatus that reduce release of dust generated during rotary dumping of rail cars in a dumping facility. The method includes removing dust laden air from a space bounded by a backside airflow diverter, a rotational frame, a first baffle and a second baffle while the rotational frame is rotating with a rail car by drawing the dust laden air through a secondary air intake that passes through the backside airflow diverter into a backside hood. A dust control apparatus includes a diverter, overlying a backside hood having a concave curved upper surface; and at least one secondary air intake positioned to pass through the diverter being located approximately where pressure in the backside hood remains neutral or negative relative to a pressure even there is a transient increase in air pressure in a lower portion of the backside hood.

Abstract: An apparatus for rotary dumping of rail cars, including a material receiving pit. A rotary rail car dumper includes a rotational frame supporting at least one baffle. The rotational frame is configured to dump a load from a rail car during rotational motion of the rotational frame between an upright position wherein the entire load is in the rail car and a dumping position wherein the load can exit the rail car. A backside airflow diverter is located beneath the rotational frame and includes a curved upper surface. A lower margin of the at least one baffle contacts the curved upper surface during at least part of the rotational motion of the rotational frame.
