Version 1.0
Issue Date: April 2024


This unit of competency applies to operators who are responsible for preparing materials for grinding; grinding materials and distributing ground materials.

This competency is typically performed by operators working either independently or as part of a work team. At all times they would be liaising with other members of the team.

This unit of competency covers the grinding and size reduction of raw materials, materials in process, product and scrap/recycled material. It involves monitoring the process, ensuring a safe work environment, rectifying problems and facilitating output changes.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 studies/scenarios 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 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment

Individual enterprises may choose to add prerequisites and co-requisites 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.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

recognising process conditions which will lead to out of specification production and taking appropriate action

implementing the enterprise's 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

electrical/instrument reading variations

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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
