Elements and Performance Criteria

1. Prepare to grind materials
   • Check equipment for hazards, danger and isolation tags in accordance with standard operating procedures
   • Perform checks to ensure all doors, inspection openings and guards are in position and secure
   • Make adjustments to equipment settings to ensure conformance with standard operating procedures
   • Notify appropriate personnel of intention to start equipment
   • Conduct additional pre-start checks as required in accordance with standard operating procedures
   • Ensure an adequate supply of materials is available to meet production requirements
2. Grind materials
   • Start equipment in sequence in accordance with standard operating procedures
   • Monitor instrument/control panels and adjust as necessary to remain within specified operating parameters
   • Make physical inspections of plant and equipment at specified intervals to identify any anomalies in standard operating procedures
   • Maximise product throughput and efficiency to maintain target parameters
   • Communicate with appropriate personnel regarding the status of operations in line with enterprise requirements
   • Employ safe working practices which conform with occupational health and safety (OHS) and enterprise requirements
   • Shut down equipment in accordance with procedures and complete required records
3. Rectify routine problems
   • Identify the range of faults that can occur during the operation
   • Determine and rectify faults caused by procedures
   • Identify and rectify equipment failure causes in accordance with procedures
   • Make sure appropriate records and log books of equipment operations are maintained to meet procedures
   • Identify non-routine problems and report to designated person
4. Distribute ground product
   • Distribute ground materials to their correct silo/storage area in accordance with standard operating procedures
   • Monitor silo/storage areas to ensure compliance with enterprise storage quality/quantity requirements.
5. Control hazards
   • Identify hazards in the grinding work area
   • Assess the risks arising from those hazards
   • Implement measures to control those risks in line with procedures
   • Shut down in an emergency as required

Required Skills

Required skills

Required skills include recognising process conditions which will lead to out of specification production and taking appropriate action implementing the enterprises standard procedures and work instructions and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of grinding equipment reading and numeracy is required to the level of interpreting workplace documents and technical information

Required knowledge

Required knowledge includes startup and shutdown processes construction and limitations of the grinding equipment and conditions grinding fundamentals out of specification situations physics and chemistry where appropriate of process principles of operation of process control philosophy of process distinguish between causes of faults such as raw material variations mechanical abnormalities electricalinstrument reading variations

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency
Critical aspects for assessment and evidence required to demonstrate competency in this unit	It is essential that the equipment and process be understood and that the importance of critical material properties is known Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in reporting the condition to the appropriate individual Consistent performance at the required standard should be demonstrated In particular look to see that types of materials to be ground and their additives are identified individual material feed and distribution systems are understood OHS and safe work practices are followed signage tags and isolation procedures are followed basic maintenance and inspection practices are carried out Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency
Context of and specific resources for assessment	Assessment will require access to an operating plant over an extended period of time or a suitable method of gathering evidence of operating ability over a range of situations Assessment will occur over a range of situations which will include disruptions to normal smooth operation Simulation or case studiesscenarios may be required to allow for timely assessment of parts of this unit of competency Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components A bank of scenarioscase studieswhat ifs and questions will be required to probe the reasoning behind observable actions
Method of assessment	Individual enterprises may choose to add prerequisites and corequisites relevant to their processes
Guidance information for assessment	Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Procedures	All operations are performed in accordance with standard procedures and work instructions.
Ground materials	Ground materials may include: quarried materials cement clinker lime ceramics and clay ground minerals glass concrete waste fibre cement
Equipment and unit operations	All such items of equipment and unit operations which form part of the grinding system. These may include: ball mills hammer mills roller mills pans edge mills other equipment integral to the operation of the grinding system
Typical problems	Typical problems may include: out of specification grinding media variations in temperature and moisture variations in feed product discharge problems
OHS	The identification and control of hazards and the application of OHS is to be in accordance with current, applicable legislation and regulations, and company procedures. All work is carried out at all times in accordance with these requirements
