A slag slurry drum filter cleaner for a drum filter mounted for rotation about an axis of rotation (3) and comprising a mesh filter (4); the cleaner comprising at least one spray nozzle (10), a nozzle mounting (13, Fig 4); a fluid supply (34, Fig 6a), and a controller. The at least one spray nozzle is adapted for movement on the nozzle mounting along of the length of the drum; and the controller controls supply of fluid to the nozzle, or each nozzle. A slag slurry drum filter cleaner for a drum filter mounted for rotation about an axis of rotation and characterised by valves (35, 36, Fig 6a) associated with each spray nozzle, and a method of controlling operation of a slag slurry drum filter cleaner, the method characterised by detecting completion of at least one revolution of the drum filter; terminating fluid flow at the first position and causing fluid to flow to one or more nozzles at a second position relative to the drum filter, is also disclosed. Advantageously the cleaner provides a more effective cleaning mechanism that allows all or a portion of the flow available from a high pressure mesh cleaning pump to be directed over a smaller portion of the mesh and hence increases the cleaning effectiveness in that area. |
