Description
This unit of competency covers the skills and knowledge required to operate an internal mill blender and ancillary equipment that is integral to the process. Internal mill blenders, such as Intermix and Banbury machines, are typically used to prepare rubber compounds for production processes, such as calendering, extrusion and ultimately tyre building, moulding, rubber lining, roller building and conveyor belt manufacture.This unit of competency applies to operators who are required to collect materials, check materials to ensure no contamination, weigh and add materials to the mill according to recipe, operate the equipment and recognise routine and non-routine problems and take appropriate action.This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members, team leader and supervisor, as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.
