Description of a Automax

The Pegson Automax is a ‘cone’ type

rock crusher. The crushing action is

 provided by an eccentric sleeve that is

mounted on heavy-duty roller bearings.

Stone is feed into the machine, and 

crushed between two replaceable liners.

The inner liner is free to rotate above theeccentric.

The outer liner is held stationary by six

hydraulic cylinders working in

conjunction with a wedge ring assembly.These cylinders also act as a overload 

release. The cone is lubricated by a

separate oil tank with a air blast oil cooler.

Introduction

This Safety Instruction (SI) is issued to assist Employees of BL PEGSON LTD to understand the requirements for the wearingof Personal Protective Equipment at Work 

1/ Application of the Regulations

1.1 The Health and Safety at Work etc Act 1974 (HSWA) requires employers to ensure the health

safety and welfare of their employees and persons not in their employment who may be affected 

 by work activities.1.2 Regulation 3(1) of the Management of Health and Safety at Work Regulations 1999 requires

employers to identify and assess the risks to health and safety present in the workplace. This

general risk assessment should identify whether there is a risk of injury to persons from working

 processes, procedures and practices. Where there is a risk identified, all practical measures shall be

taken to eliminate or reduce so far as is reasonably practicable exposure of the individual to those

risks. There is in effect a hierarchy of control measures and Personal Protective Equipment (PPE)

should always be regarded as the 'last resort'

1.3 The Personal Protective Equipment recommended for each group of people will be commensuratewith their experience and knowledge of the risks to which they are being exposed in any particular 

working area.

1.4 This document details the ways in which BL PEGSON LTD discharges its duties and obligations

to its employees, contractors & sub-contractors, customers, suppliers and visitors under this

requirement.

2/ Personal Protective Equipment

'All equipment designed to be worn or held by a person at work to protect against one or more risks and any addition or 

accessory designed to meet this objective'

2.1 Both protective equipment and clothing are within the scope of the definitions and therefore:

8/16/2019 Cone Build Manual Manutenção

http://slidepdf.com/reader/full/cone-build-manual-manutencao 53/131

 Advanced Crushing Technology 53

2.1.1 For the sake of this Safety Instruction 15/01/01 protective clothing such as overalls (when they

are Proban Treated or Pyrovatec) aprons, protective clothing for adverse weather conditions,

gloves, safety footwear, safety helmets, high visibility waistcoats etc; and 2.1.2 Protective equipment such as eye protectors, hearing protectors, respiratory protectors, face

 protectors and safety harnesses

2.1.3 Overalls other than Proban Treated or Pyrovatec will not be regarded as PPE as they are for 

welfare purposes and do not provide health and safety protection.

2.2 Selection of appropriate PPE will always be the factor that proves the item to be adequate or not

for example: when working with equipment i.e. hammer and chisel, that produces fragments and 

splinters impact protection safety glasses with side protection or wrap-round. When operatingequipment that produces fine grit or offshoot i.e. grinder or cutting disc face mask with safety

glasses or box goggles. When working with hazardous substances or splashes invariably box

goggles should be selected.

2.3 With consideration given to the advice above anyone that feels they have insufficient knowledge

or experience in the selection of appropriate PPE they should consult their supervisor or Health

and Safety Officer for a risk assessment and necessary training.

3/ Contractors and Sub-ContractorsWhen contractors and sub-contractors are employed to carry out work that comes within the scope of this Safety

Instruction SI 15/01/01 they will be expected to comply in all factors as though they are direct employees of BL-Pegson Ltd.

(See section 5/ Personal Protective Equipment for employees)

4/ Personal protective Equipment for Customers, Suppliers and Visitors

4.1 When customers, suppliers and visitors to BL-Pegson are introduced to production areas theymust be equipped with adequate and appropriate Personal Protective Equipment (PPE).

It shall be the responsibility of the host responsible for the customer, supplier or visitor to ensure that PPE is

readily available prior to any entry to production areas.

4.2 The needs of paragraph 4.1 above may require the host to make pre-visit arrangements for some

customers, suppliers & visitors to provide their own PPE or provide sufficient information as may be necessary

to enable BL-Pegson ltd to obtain the appropriate clothing and or equipment.

8/16/2019 Cone Build Manual Manutenção

http://slidepdf.com/reader/full/cone-build-manual-manutencao 54/131

 Advanced Crushing Technology 54

4.3 Adequate and appropriate Personal Protective Equipment for all customers, suppliers and visitors

consists of;4.3.1 High visibility vest

4.3.2 Safety footwear with internal steel toe cap

4.3.3 Grade 2 impact eye protection

4.3.4 Hearing protection (all customers, suppliers and visitors will be advised to wear the hearing

 protection, as, during production hours the background noise levels in production departments is

above the first action level of 85dB(a) whereby hearing protection must be provided.

4.4 Hosts escorting suppliers, customers and visitors to production areas who are not in compliance

with the above guidelines will be asked to leave the production area until appropriate remedial

action has been taken.

4.5 Persistent failure by an hosts to establish his customers, suppliers and visitors with the above

requirements will result in the instigation of the BL-Pegson Ltd progressive disciplinary procedures

against him/her.

5/ Personal Protective Equipment for Employees

5.1 Guidelines With due regard to the section 2.2 of this document, the following guidelines are set out

for PPE to be used by all BL-Pegson personnel when performing tasks in all production,

maintenance and testing areas.

5.1.1 When any employee is travelling through or working in a production, maintenance or test area (as

outlined in section 5.2 of this Safety Instruction), other than his/her normal working area, s/he will

 be regarded as a visitor to the area. In these circumstances, as a visitor to an area s/he will be

required to adopt PPE (foot and eye protection) as a minimum basic requirement. Persistent failure

 by any employee to conform with the designated requirements, for the use of personal protective

equipment within any production, maintenance or test area will result in the instigation of the BL-

Pegson Ltd progressive disciplinary procedures against him/her.

 Advanced Crushing Technology 55

5.2 Application of S.I. For the purpose of this Safety Instruction a production, maintenance or testing

area, is anywhere on the Mammoth Street Site inside or outside of buildings, that;

5.2.1 machining, fitting, welding, burning attaching and/or removing, adjusting or testing of units or components to any item of equipment that goes to make up a crushing or pumping plant; or 

5.2.2 any item of equipment used in the production, testing, adjustment or maintenance of crushing or 

 pumping plant; or 

5.2.3 any location other than BL-Pegson Ltd Mammoth Street Site, where BL-Pegson personnel are

involved in the repairs, maintenance, adjusting or testing of any BL-Pegson manufactured plant and 

or equipment.

5.3 Minimum/Recommended Requirements5.3.1 Foot Protection - Basic safety footwear protects the feet / lower leg of individuals, assessment has

indicated that the primary protection required at BL-Pegson ltd is Toe Protection (200 joule toecap

 protection), Oil and Water Resistant with anti-slip soles with steel mid-sole (100 Newtons

 penetration resistance) for protection against penetrating objects.

Safety shoes or Safety Boots shall be worn at all times inside production and maintenance areas.

5.3.2 Leg Protection -

Gaiters or knee-high boots shall be worn when pouring molten metals.

5.3.3 Thigh Protection -Leather apron should be worn when disc cutters and grinders are being operated at or below waist

level.

 Nitrile coated or rubber apron should be worn when decanting or using hazardous liquids.

5.3.4 Whole Body Protection -

Proban overalls (flame retardant coating) should be worn when general welding and grinding

 processes are carried out by an individual.Operators performing high intensity welding processes shall wear Pyrovatec overalls (heavy-duty

cotton with tight knit fabric and flame-retardant coating).

 Advanced Crushing Technology 56

5.3.5 Hand Protection - Gloves giving a level of 

Cut and puncture protection gloves should be worn when performing tasks employing sharp

 bladed and pointed tools.

Cut and puncture protection gloves should be worn when performing lifting and handling tasks

on items of equipment or materials that may have rough edges or protruding wires etc.

Thermal protection gloves should be worn when processes require the

Handling of hot or cold items of equipment or materials, this is of particular significance in the

handling processes entailed in the use of liquid nitrogen.

Welding gauntlets should be worn when operating profile cutting / burning equipment and 

welding.Rubber or Nitrile coating gauntlets / gloves should be used when working with hazardous

substances.

Nitrile or latex disposable gloves are recommended when working with other non-hazardous

fluids.

5.3.6 Eye Protection - The selection of correct eye protection is the primary consideration for an

individual when performing any task, poor selection is of no benefit to the individual and in somecases can make a situation worse. The reasoning behind this being that having made their 

selection they believe themselves to be protected from any hazard. All eye protection PPE issued 

at BL-Pegson Ltd is to EN166 Category 2.

Prescription lenses impact protection glasses all individuals that are required to wear

 prescription spectacles will be issued with prescription safety glasses with grade 1 impact lenses

and side shields. There may be occasion where additional protection shall be required for 

 protection from splashes or dust particles in which case a box goggle shall be worn over the top

of the prescription lens safety glasses.

 Advanced Crushing Technology 58

Tinted glass or Speedglass (electronic polarising action)

WeldingProfile cutter operation

Oxy acetylene burning

Any other situation, not included in this list whereby a potential for eye damage from a working process or procedure is present,

should be assessed by the section Team Leader and or the Health and Safety Manager. Appropriate protection commensurate with

the level of risk assessed should then be applied and this safety instruction amended.

5.3.7 Respiratory Protection - as with eye protection, respiratory safety hazards are extremely difficult

to protect against, as poor selection can lead to individuals feeling they are adequately protected and 

yet not receiving any of the protection required for the situation. Dust, Gas and Vapour are specific

hazards and a filter protecting against mist and fume will not necessarily protect against dust

(particulate), similarly a particulate filter will not protect against gas and vapour.

Respiratory protection should only be selected as the last resort. All other sources of to control the

hazard should be considered first e.g. substitution, elimination, separation and engineering controls.

Respiratory Protection - when not in service all respiratory protective equipment must be kept in aclean dry environment where it can be protected from contaminants. Reusable equipment should be

wiped down with a mild solution of soap and water using a cloth or sponge, dried off and then

stored in a clean dry environment.

Powered air and Airfed Respirators and headtop should be worn when

High intensity welding processes (Particulate filter P(SL) filters must be fitted at the air intake. It isrecommended that in addition Organic gases and vapours with boiling point greater than 65oC;

inorganic gases and vapours and acid gases (A1B1E1) filters, should also be fitted at the air intake.

Paint spraying Plants etc. (Particulate filter P(SL) +Organic Vapour (OV) filters must be fitted at

the air intake.

Compressed Airline Feed Respirator and headtop must be worn when

Grit blasting.

 Advanced Crushing Technology 59

Half mask respirators should be worn when

Stick welding (Particulate filter P(SL) It is recommended that in addition organic gases and 

vapours with boiling point above 65oC; inorganic gases and vapours (A1B1) filters

should also be applied.

Paint spraying smaller items, short period, (Particulate filter P(SL) +Organic Vapour 

Disposable particulate Respirators

Polishing surfaces with die grinder and flap wheels (Particulate filter P(SL))

De-burring / fettling equipment (Particulate filter P(SL))

Any other situation, not included in this list whereby a potential for respiratory damage from a

working process or procedure is present, should be assessed by the section Team Leader and or theHealth and Safety Manager. Appropriate protection commensurate with the level of risk assessed 

should then be applied and this safety instruction amended.

5.3.8 Hearing Protection - The Noise at Work Regulations 1989 require hearing protection to be

 provided where noise levels are between 85dB(A) and 90dB(A). Where noise levels are in excess

of 90dB(A) hearing protection becomes a mandatory requirement.

Noise level assessments have been carried out across the site and the results illustrate that when

 production departments are in normal operation the background level of noise is in excess of 

85dB(A). The company has made provision therefore for hearing protection to be available in all

 production departments.

Fabrication Department, Quarry Plant Fitting Department and Quarry Plant Assembly

Departments results have indicated that the levels of exposure in these departments are in excess

of 90dB(A) in these departments therefore personal hearing protectors (Variphone) have been

offered to every employee. Being manufactured to suit an individual's ear canal these can be worn

for 8 hours per day with no discomfort and can be attenuated to match each individuals exposurelevels.

For those persons that have declined the offer of the above (Variphone) service a variety of styles

of hearing protection are available and the individuals selection must be worn every time they are

exposed to levels of noise in excess of 90dB(A)

Styles available:

Disposable foam Inserts - can be used alongside other PPE easy to use and provide levels of protection that can

exceed some earmuffs. Some come moulded for greater comfort. Must be disposed of after each wearing and new used each time. For effective operation the insert should be rolled between finger and thumb, the ear canal

should then be opened slightly by lifting the upper part of the ear, using the opposite hand the ear having the

insert applied to. The tightly rolled insert is then pushed into the ear canal and allowed to expand to create an

effective seal.

Corded inserts - a variety of  types, foam, some with durable cleanable coatings for extended use, re-usable

moulded plastic. Any insert that is re-usable should be cleaned in a mild solution of soapy water at least eachday. This type of insert is fitted in the same way as described above.

Banded inserts - coated foam inserts and moulded plastic inserts, hang comfortably around the neck and ideal

for intermittent protection needs. To fit effectively the ear canal should be eased open slightly by lifting the

upper part of the ear using the opposite hand to which the ear protector is being applied. The plug or shaped 

 plastic pod should then be eased into the ear canal until a good seal is formed the ear should then be released.

Ear Muff  - 3 basic styles Helmet Mounted, Overhead Band or NeckBand. For the muff to be effective a good 

seal must be established between the soft outer part of the muff and the area of the head around the ear. Long

hair, beards and spectacles can impair the seal of the muff and thereby effect the physical performance of the protection. The earmuff should always be fitted in the vertical position as any other position will seriously

impaired as an effective seal will not be achieved.

When not in service all re-usable hearing protectors must be kept in a clean dry environment where they can be

 protected from contaminants. Reusable equipment should be cleaned in a mild solution of soap and water, dried 

off and then stored in a clean dry environment.

5.3.9 Head Protection - As a general rule head protection is not required in production or maintenanceareas at BL-Pegson. However when Plants are undergoing display or test programmes in the field

Safety Helmets are a mandatory requirement for all BL-Pegson personnel when operating, testing, repairing or 

adjusting Plant and Machinery at a quarry or demolition / recycling site.

Bump caps are available for all personnel and are recommended for use when working on Plants and Machines

in production and maintenance areas at the Mammoth Street Site.

5.3.10 Fall-arrest Protection - must be worn when working at heights where adequate provision for 

guard-rails to prevent falls cannot be established.

Body Harness and attachment systems are available, that can be adjusted to fit the individual.

The attachment system must be connected to a reliable anchorage point. The vertical drop of theuser must be minimised to prevent collision with obstacles and the braking force injuring, tearing

or causing the operator to fall.

Inspections of the equipment must be carried out prior to use to check for wear and damage that

may cause the equipment to fail in operation.

The equipment should be examined every six months in accordance with the Lifting Operations

and Lifting Equipment Regulations 1998.

When not in service all fall arrest protection equipment and attachments must be kept in a clean dry environment

where they can be protected from contaminants. Reusable equipment should be cleaned in a mild solution of soap

and water, dried off and then stored in a clean dry environment.
