A method for cleaning primary packaging means in pharmaceutical filling and/or packaging installations. The method includes a step of treating at least one surface of the primary packaging by means of blasting with carbon dioxide (CO2) snow, a step of using a gas flow for the suction extraction of substances cleaned off from the surface, and a step of filtering the gas flow comprising the substances contained in the cleaned-off substances. A related system includes a supply device for supplying liquid CO2 and compressed air to at least one nozzle designed to generate solid particles by means of expanding the liquid CO2 to be directed onto a surface to be treated, a holding device for primary packaging, a substance removal device to remove substances cleaned from at least one surface by means of a gas flow; and a filter device for the gas flow comprising the cleaned substances.

A shot blasting cabinet with adjustable impellers includes a cabinet, a plurality of impeller apparatuses, and a plurality of adjusting devices. A shot-blasting working line is defined between an inlet and an outlet of the cabinet. The impeller apparatuses are symmetrically disposed on upper and lower sides of the cabinet. Each impeller apparatus has a protective housing, a driving device, a pair of rotary plates, and a plurality of impeller blades. The driving device connects one of the rotary plates. The protective housing covers the pair of rotary plates and the impeller blades, and defines a shot-blasting exit surface. The shot-blasting exit surface communicates with an interior of the cabinet. The adjusting devices are used to adjust an angle and a distance of the shot-blasting exit surface relative to the shot-blasting working line.

A waterjet system is provided, including a pump configured to pump fluid, an electric motor configured to drive the pump, a hopper configured to store abrasive, and a mixing chamber configured to mix abrasive from the hopper and the fluid from the pump to produce a slurry. A cutting bed is configured to receive a workpiece to be cut. A cutting head is configured to expel the slurry through the outlet nozzle as a high-velocity jet into the cutting bed.

A method for the surface treatment of workpieces by means of abrasive media, and a surface treatment composition. The method comprises the steps of providing a treatment tool, providing an abrasive medium, supplying a workpiece having a surface to be treated, surface treating the workpiece, involving removal of material and producing waste products, and processing the waste products, wherein at least one of said steps comprises adding an additive to lower a self-ignition tendency on the part of the waste products, the additive comprising a salt, composed of a carbonate and/or of a halogen anion.

An apparatus for treating a surface has a vehicle including an extensible boom. A multi-purpose hood is attached to the boom. The hood includes at least one nozzle for spraying a fluid through an outlet of the hood, the nozzle adapted for reciprocating, non-rotational movement in a generally linear direction relative to the opening in the hood. The multi-purpose hood may be adapted for rotating independently about three different axes, and may include a first actuator for controlling a roll of the hood, a second actuator for controlling a yaw of the hood, a third actuator for controlling a pitch of the hood, and a fourth actuator for controlling an extension of the boom and a second actuator for controlling a swing of the boom. The extensible boom may be connected to a telescoping conduit for communicating fluid along the boom to or from the multi-purpose hood. Related methods are also disclosed.
