RELIABILITY CENTRED MAINTENANCE STRATEGY 2
Reliability Centred Maintenance Strategy
This is a report paper concerning the reliability centred maintenance strategy for a
factory equipment used in the processing of dust. The dust being fed into this equipment is
from another factory and is then loaded by the use of wheeled shovel into the hopper and then
elevated by bucket elevator and conveyor to the system’s apex. The dust is then disseminated
to the hoppers for storage by a huge conveyor of scraper chain. This report paper focuses on
the maintenance strategy of the dust equipment. The strategy will be contributing to a factory
reliability centred maintenance strategy. The figure below shows the reliability centred
maintenance strategy which should be implemented by the factory for effective maintenance
of the dust equipment (Abdulrohim, 2011).

The maintenance is eyed to the identification of the equipment in question, seeking to
maximize the strategies of maintenance to reduce the failure of the equipment and maximize
the availability and reliability of the equipment. The steps involved in the implementation of

RELIABILITY CENTRED MAINTENANCE STRATEGY 3
the reliability centred maintenance above are seven as shown in figure 1 above. These seven
steps have been explained below in regard to the dust equipment (Dixey, 2010).
Step 1: Equipment selection for the purposes of maintenance
The initial step of maintenance in this strategy is the process of equipment selection
that is to be maintained. The selected equipment should be critical in terms of its previous
cost, previous costs of repair, and effects on the general operation of the machine. The parts
of the equipment that can be selected for the purposes of maintenance include making
machine extruder, making machine mixer, machine feed hopper, extract conveyor, dust
hopper, scraper chain conveyor, bucket elevator, and large wheeled loading shovel (Kumar,
2013).
Step 2: Defining the function and boundaries of the systems containing the equipment
selected
The equipment that is to be maintained belongs to a section of the machine which
performs a critical function. The following are the systems in the dust equipment together
with their boundaries and their functions. The inclined conveyor is a system made up of belt
conveyor with idlers that are toughing and is driven using shaft mounted gearbox. Its function
is to raise dust beneath the ground hopper (Shayer, 2010). The collection conveyor,
machine feed conveyor and collection conveyor are belt conveyor possessing toughing idlers
and are driven using shaft mounted gearbox. Their functions are to remove dust from the
hopper.
The maintenance difficulty of these belts are easy and their complexities are low. The
making machine mixer has a single shaft mixer with high blades of chrome steel. The
function of the making machine mixer is to mix lime and dust water. The complexity of this
system is very high and it is very difficult to maintain. The making machine extruder has a
