    The global demand for animal feedshas never been higher, fuelled

    by increasing heavy consump-

    tion of meat in China and wealthy

    countries in the ASEAN block.

    This demand means that continuity of

    supply is all important, placing stress all along

    the supply chain from processing and trans-

    ferring of raw materials and finished product

    in animal feed plants, to handling, conveying

    and storing the product at ports for onward

    shipping.

    Handling solid and liquid ingredients

    together with binding agents makes the

    whole process of producing animal feed

    an activity where success depends on theequipment remaining reliable, 24-hours a

    day.

    However, militating against this is the

    nature of animal feeds themselves.

    The operations of processing, mixing,

    blending, conveying and transferring bring

    large volumes of semi-aggressive media into

    contact with a variety of plant surfaces. This

    media has the capability to wear out hop-

    pers, feeders, chutes and mixing equipment

    very quickly, resulting in lost production and

    excessive maintenance costs.

    Whether the feed is conveyed as dried,

    mixed or packaged, the process c reates wear

    problems.

    Depending on the volumes and the oper-ational regime, these will significantly reduce

    the value of the processing companys capital

    equipment if the plant is not wear protected

    for continual operation.

    Constant wear, leading to frequent

    repairs and maintenance can be avoided if

    the correct wear protection is applied. The

    result is drastically reduced cost of repairs

    on worn-out chutes, ruptured pipelines,

    crumbling silos and conveyors.

    Eliminating these on-going wear and

    repair concerns enables the process to

    operate as designed, maximising its efficiency

    ment and improved ROI in the animal feed

    processing business.

    Operational factorsIn common with other bulk materials han-

    dling industries, the equipment for processing

    and conveying animal feeds needs to cater

    for many operational factors. If considered

    from the onset, these factors can be catered

    for and a design element introduced to com-

    pensate for potential wear problems.

    Factors such as volumes, loadings, par-

    ticle size and shape, viscosity and moisture

    content are typical criteria that must be

    addressed in order to eliminate potentialproblem wear areas.

    Selecting the right liner materials, hopper

    design and pipe installation can prevent the

    need for replacement and maintenance for

    up to 20 years.

    No maintenance requirements over

    the lifetime of an installation means

    reduced risk, reduced cost and more pro-

    duction uptime over longer periods all of

    which are critically important to improve

    the efficiencies of companies that operate

    24/7, said John Connolly, managing direc-

    tor of the UK wear protection specialist,

    Kingfisher Industrial.

    Complex and multi-layeredIn quantitative terms the benefits to the

    plant user are huge, because maintenance of

    process plant and equipment is a complex

    and multi-layered operation.

    Avoided are the ongoing cost problems

    of interruptions to production as a result of

    breaking down pipework; the requirement

    for specialist labour, and the safety risks

    involved with personnel working at height,

    performing hot work and lifting operations.

    In addition, the tasks of organising access

    platforms and plant hire, with their attendant

    costs and risks are no longer necessary;

    nor are procedures devised for the cleaning-up of spillages that may occur when process

    pipework is perforated, thus creating an

    environmental issue or potential breach of

    legislation.

    As a result, the system user benefits from

    continuous operational gains, which defray

    the cost of the protection system, guarantee-

    ing a prompt return on investment.

    Using a combination of ceramic, metallic

    and polymer lining systems, Kingfisher has

    had overwhelming success in protecting

    equipment and extending the service life of

    bulk materials handling plant.

    In many instances, the benefits of protect-

    ing plant are threefold: in addition to protect-

    ing against wear, the low friction nature of

    the lining material reduces energy usage and

    increases production by allowing a greater

    volume of material to be throughput.

    A major benefit of wear protection is

    that it can be employed at any time in the

    life of a process system, so users do not have

    to throw away their existing plant and start

    again, says John Connolly.

    In addition, because high conveying

    speeds and abrasive mate-

    rials cause wear of varying

    intensity at different points

    in process plant systems,it is often the case that

    protection need only be applied to areas that

    are most vulnerable to wear, further reduc-

    ing upfront costs and improving ROI for the

    system user.

    Protection from inceptionIf a process sy stem is designed with wear

    protection from its inception, then overall

    equipment costs can often be reduced

    because the system chosen to protect the

    equipment can often remove the require-

    ment to manufacture components using

    heavier grades of material.

    the pipework for the Kingfisher solution

    was manufactured and lined with K-BAS

    at Kingfishers purpose- built factory in the

    West Midlands, and then delivered to site

    for final assembly. Assembly of the pipework

    was carried out, in this instance, because of

    timing, by the feed suppliers own mainte-

    nance personnel. However, Kingfisher gener-

    ally takes full turnkey responsibility in the

    wear protection projects that the company

    handles.

    We provide a full turnkey service with

    our wear protection systems, including com-

    plete installation and commissioning, said

    John Connolly. Our customers generally like

    this approach, as it keeps everything under

    one roof, giving them the security of a single

    source supply from a partner company theycan trust.

    About Kingfisher IndustrialKingfisher Industrial provides wear solu-

    tions for process plant used to convey, proc-

    ess or store bulk solid materials, in either

    dry or hydraulic states. With its range of

    ceramic, metallic and polymer protection sys-

    tems, Kingfisher can overcome wear problems;

    engineering suitable protection systems that

    can add many years of life to a plant, and in

    some cases outlast the design life of a process

    completely.

    These solutions cater for the operat-

    ing criteria, budget and life cycle of either

    new equipment - particularly when initially

    installed - or existing equipment, which can

    be retrofitted with a protection system to

    add to its current asset value.

    equipment against unplanned main-

    tenance and costly downtime are

    evidenced by a 2003 application of

    the technology at a major animal feed

    supplier in Shropshire.

    The company was experiencing

    constant problems of perforation in

    pipes, along which abrasive animal

    feedstuffs were conveyed pneumatically at

    high speed. A number of solutions were

    tried, but the frequency of replacements

    and downtime resulting from these led to

    an approach to Kingfisher Industrial, which

    advised another approach, based upon the

    companys ceramic K-Bas Cast Basalt Lining

    System.

    With a hardness rating of approximately

    eight on the MOHS hardness scale, K-BASoffers key benefits, such as resistance

    to friction-

    induced

    abrasion

    and ero-

    sion in

    plant

    where bulk

    solids are

    conveyed,

    stored

    and proc-

    essed by

    mechanical,

    pneumatic

    or hydraulic means. In addition, K-BAS

    is a relatively inexpensive form of wear

    protection, which is corrosion resistance,

    and offers the additional advantage ofpromoting material flow.

    K-BAS is one of the many liners we offer,

    said John Connolly. There is no one-size-fits-all

    philosophy in respect of wear protection, thats

    why we always carefully analyse all aspects of

    the equipment, site and surrounding environ-

    ment before we put a firm solution proposal

    before our customer. What we are aiming

    to achieve is the longest possible operating

    life from an installation, to payback the initial

    investment many times over. Our success is

    evidenced by installations such as the one in

    Shropshire, which is now in its eighth year of

    operation, with no problems to report.

    In the case of the Shropshire installation,

    In addition, involving a wear specialist

    such as Kingfisher at the design stage of proc-

    ess conveying equipment can streamline the

    design, optimising process efficiency through

    reduced turbulence and improved material

    flow, at the same time ultimately delivering

    improved service life.

    Kingfisher has produced a graphic to

    highlight the benefits of its whole life cost

    argument (see Table 1). The graphic com-pares the ongoing costs associated with

    equipment and installations that do not ben-

    efit from wear protection, with the one-off

    (i.e. purchase) costs of enhanced protection,

    highlighting the continuous operational gainsof the latter investment strategy.

    The thrust of the argument is clear

    when considering the typical example of an

    enclosed pipework system for conveying

    bulk materials. The system is wear protected,

    and so is able to provide up to 20-years of

    life. With this one-off approach, the system

    user has little or no maintenance require-

    ments over the lifetime of the installation.

    He does not have the ongoing cost prob-

    lem say every 4-years - of breaking the

    pipework system down - and of interrupting

    production in the process.

    tion as a safeguard for animal feed processing

    Topical liquids used in the extrusion process of pet food

    manufacturing are sticky and particularly hard to clean, especially

    when they congeal in colder weather.

    Before changing to Tapco urethane

    buckets, wed sometimes have to

    stop production and clean twice a

    day, Jeff Bowman, Extrusion Plant

    Manager, Spectrum Feed Services,Ltd. says. That meant allocating

    2-3 hours for two staff members to

    hand scrape every bucket on our 60-foot-tall legs, each time.

    Trust me, nobody liked THAT job.

    Cross-contamination was also a constant concern and led to

    more rework to maintain product quality.

    After consulting with Tapco, Spectrum had Proactive Industrial

    Maintenance replace the existing buckets with FDA-compliant

    urethane resin CC-HD buckets. Tapco urethane buckets resist

    product adhesion and flex to release caked-on build-up.

    Now sticky extruded pellets and kibble slide right out of Tapco

    urethane buckets, Bowman says. We went from scraping buckets

    twice a day, to cleaning on a weekly schedule, without concerns

    of cross-contamination, Bowman says. The cleaning process isfaster and easier, too, which is important when youre

    processing 140 tons a week.
