and tyre industry.

7. Make in India is an initiative launched by the Government
of India in 2014 to encourage multi-national and national
companies to manufacture their products in India. While
this initiative has garnered significant international
attention and keenly watched, some Indian machinery
companies have been steadily building up their repute with
global approach and right technology.
In this special edition of Know Your Supplier’s cover story,
we feature one such company Bharaj Machineries Pvt. Ltd.,
through an interactive conversation with Amardeep Singh,
Director - Sales Projects.
Established in 1982 with a vision, to always produce most
advanced and quality machineries for the rubber industry,

Things You Should

This section is bought to you in association with our brand display partners

If you have seen or used an Internal Mixer,
Bale Cutter, Press, or any Hydraulic
machinery then you have witnessed a
Hydraulic Power Pack in operation.
Here are 13 things you should know about
Hydraulic Power Pack.
Image Source: RMF
Know Your Supplier | JUNE 2016

30. | INSIGHT |
1.By definition, hydraulic power packs are
self-contained power-units used instead
of a built-in power supply, to transmit
power from one location to another and
thus run your rubber machinery. A
hydraulic system employs enclosed fluid
to transfer energy from one source to
another, and subsequently create rotary
motion, linear motion, or force.
2.Hydraulic power packs come in different
shapes and sizes; some are very large and
stationary whereas others are smaller
and compact. The mechanical
characteristics and specifications of a
hydraulic power pack dictate the type of
applications for which it can be effective.
3.You can identify hydraulic power packs
through its main components. Because
irrespective of the size of the unit, all
power packs will have the following;
▪ A hydraulic reservoir (or tank) which holds
the enclosed oil. This is a storage unit
designed with enough volume for the oil in
the pipes to drain into it. They also ensure
this oil is stored and maintained in the best
possible condition. Reservoirs will come in
different sizes. Common auxiliaries for a
reservoir include filler/breathers and drain
ports, level gauge, level switches and
inspection covers.
▪ Regulators that control and maintain the
amount of pressure that the hydraulic
power pack delivers. These are very vital.
▪ Pressure Supply lines and Relief lines. The
supply line supplies fluid under pressure to
the pump and the relief lines relieve
pressure between the pump and the valves.
The relief lines also control the direction of
flow through the system.
▪ Motor to power a pump
▪ A pump to perform two actions. Firstly, it
creates a vacuum at the pump inlet and
with the help of atmospheric pressure,
forces fluid from the reservoir into the inlet
line. This fluid is then fed to the pump. The
pump then delivers this fluid to the pump
outlet and force feeds it into the hydraulic
system.
4.Some of the important factors that
influence a hydraulic power unit's
performance are pressure limits, power
capacity, and reservoir volume. In
addition, its physical characteristics
including size, power supply, and
pumping strength are also significant
considerations. Reputed suppliers take
great care to ensure that a large, durable
hydraulic power unit is built for
functioning under a range of
environmental conditions.

5.Hydraulic power packs have other
components like
▪ Filters: Filtration is a critical part of a
hydraulic power pack, ensuring wear is
minimised and efficiencies are
maintained. Basic suction strainers do
not allow large contaminants to enter the
pump. Pressure filters are normally
configured at the pump outlet and ensure
only filtered oil enters the hydraulic
system. Contamination within the system
is filtered out by the return filter before it
enters the hydraulic reservoir.
▪ Pressure Control valves that limit or
control the hydraulic pressure within the
hydraulic system.
▪ Directional Control hydraulic valves
(manual, electrical, pneumatic or
hydraulic operated) direct the oil flow
around the system to operate actuators,
motors or other functions.
▪ Cooling is another other key
consideration, where efficiencies within a
system or machine will produce heat in the
oil; this must be cooled to ensure long life
and high-efficiency.
▪ Accumulators: These are containers that
can be attached to the hydraulic actuators.
They collect oil from the pump and are
intended to build and maintain fluid
pressure to supplement the pumping system.
▪ Coolers and Heaters: As part of the
temperature regulation process, an air
cooler can be installed near or behind the
filter unit to prevent temperatures from
rising above operational parameters.
Likewise, a heating system, such as an oil-
based heater, can be used to elevate
temperatures when necessary.
▪ Power Unit Controllers: The hydraulic
controller unit is the operator interface
containing power switches, displays, and
monitoring features. It is necessary for
installing and integrating a power unit into
a hydraulic systems, and can usually be
found wired into the power unit. Oil level
and temperature protection switch,
Pressure switches and filter clogging
switches are quite common.
6.Hydraulic power packs come with a
variety of valve connections. This means
that you can power a variety of rubber and
tyre machinery by using the appropriate
valves. Most manufacturers segregate their
models into a 'standard', 'mini', 'micro' or
'bespoke' power pack categories.
7.When picking a hydraulic power pack
there are a variety of pumps and options to
pick from. Hence, it is important to pick the
right power pack to meet your machines
needs. It is also important to consider a
power pack that will help maximise
productivity and minimise cost.

8. In rubber and tyre machinery, you would
need custom design of your hydraulic
power packs depending on the features
you select and how you select. For eg, you
could either opt for a single power pack
for your drop door and hydraulic ram
operations of a mixer; or choose separate
power packs for individual operations
depending on the circumstances at your
plant.
9. Your supplier should review the pressure
and flow data together with you. And
they should also take load profiles and
the thermal budget into account. Doing
this ensures that you get a power pack
that precisely meets your technical
requirements and operates economically.
10.It is ideal if you or your machinery
supplier get everything integrated from a
single source. Because, fewer interfaces
means your hydraulic system gets built
faster. Your costs are lower, too.
11.Experts recommend use of high-
efficiency low-noise internal gear pumps
when designing power packs. Your
supplier may consider accumulator
charging technology or variable speed
drives as may be the case for your
application. Multiple pressure circuits
are another option.
12.Hydraulic power packs require regular
maintenance to ensure they work
properly and safely for extended periods
of use. Maintaining hydraulic power
packs is relatively simple. You should
check the tubing for any noticeable
problems such as dents or cracks. You
should also inspect the reservoir to check
for any corrosion or rust. And do regularly
change the hydraulic fluid as per
recommended maintenance schedule of
your hydraulic power pack
13.Hydraulic power packs must be installed
and mounted in a clean and dry location
void of any standing water or accumulated
run-off.
Summarizing, you should opt for a power
pack that has low power consumption,
requires very little installation space, and
operates with low cooling requirements.
This would mean that your operating costs
are very low for the unit and it's easy to
integrate into your main machinery. All of
these would help you procure power packs
featuring high reliability and availability on
the one hand, and easy and cost-effective
integration into your rubber machinery on
the other.

The Biggest Problem with Heat
Transfer Efficiency in Rubber
Machinery (And How You Can Fix It)

38. Rubber processing has a bizarre energy
pattern, when seen from a layman's
perspective. Because you add heat into
your process and then you cool down!
Heat addition and removal is repeated in
each of your subsequent stages as well.
When you process rubber, energy is
consumed across the value chain – right
from transport of raw rubber, to the
various processing operations (be it rubber
mixing, rubber extrusion, rubber
calendering, moulding etc) to convert into
your suitable product and then
transportation of your product.
This implies that you need to cool down
your rubber processing machinery
regularly, which simultaneously involves
heat exchange from a hot medium to a
cooler medium.
And the most common medium to cool is
water.
But where there's water, you will face
water-related problems caused by its
mineral deposits. These deposits could give
you varying degrees of water-related
problems that affect your operating
efficiencies and/or even leading to more
costly equipment downtime issues.
This could be in your Rubber Machinery like
Mixer, Mixing Mill Rolls, Calender Rolls,
Press, Extruder, Heat Exchangers, Moulds,
and factory equipment like Boilers, Chillers,
Compressors, and TCU's or other Ancillary
Units, etc.
You would notice that the mineral deposits
accumulate quickly regardless of screens or
treatment actions adopted. Even a thin
coating of water scale will act to insulate the
water system's surface and retard the
transfer of heat.
Hence, scaling is the biggest problem
affecting the heat transfer efficiency in
rubber machinery.
Even a thin coating of water
scale will act to insulate the
water system’s surface and
retard the transfer of heat.

40. To increase heat transfer efficiency, lower
maintenance cost, conserve overall energy
consumption and thus enhance the usable
life of your machinery, removing scales in
all your water-cooled or water-heated
rubber and tyre equipment is very
important.
In a simple rubber machinery like the
mixing mill, the presence of scales on rolls
leads to localized hot spots affecting your
mixing quality. In the case of boilers, scales
can be very damaging leading to even
boiler rupture. When water scale, lime and
rust deposits accumulate on the water side
of chambers, rotors and the drop door of
the Mixer, it causes temperature of your
rubber stock to rise and gradually lead to a
loss in production.
Different machinery has different safe and
effective method to remove scales. Recently,

42. I was shown an instruction sheet, from one
of the descalers (RYDLYME), on the process
to descale a rubber mixer that I found
interesting.
Here's the process reproduced. I hope you
too find it informative.
1. Take mixer out of service.
2. Close water supply valve at header as
shown in the sketch above.
3. Drain all water from all sections of
mixer.
4. Connect Descaling Solution pump
discharge hose to water header. Header
usually supplies all circuits.
5. Connect return hoses to drain lines from
all circuits and place into the Descaling
Solution receiver.
6. Close water supply valves to gate and
jacket circuits.
7. Start pump and pump the descaling
solution into rotors to purge the water
from this circuit to sewer. When the
descaling solution begins to discharge
from this hose, return to the receiver.
8. Open water supply valve to gate and
maintain Descaling Solution circulation
through this circuit.
9. Open water supply valve to jacket and
maintain Descaling Solution circulation
through this circuit.
10. If any circuit is NOT flowing properly,
restrict Descaling Solution flow in other
circuits until flow returns to normal in
this circuit.
11. Circulate a total of 120 Litres of
Descaling Solution through all circuits of
mixer until clean. This will require
approximately four hours pumping time.
12. It is suggested to periodically rotate the
rotors during Descaling Solution cleaning
to assure that the Descaling Solution is in
contact with all of the lobes of the rotor.
13. Upon completion of cleaning, flush all
Descaling Solution from all circuits with
fresh water.
14. Disconnect the Descaling Solution pump
and all hoses. The mixer is now ready to
be returned to service.
15. Periodic descaling will keep the
temperatures of the mixer within
acceptable limits, assuring you a better
product and minimize burnt or
improperly mixed stock.
16. Clean out the Descaling Solution System
and store for future use.
Summarizing, scaling is the biggest problem
with heat transfer efficiency in your rubber
machinery. Descaling or cleaning the scales
helps you fix this issue. Hence incorporating
descaling solutions into your preventive
maintenance program is recommended to
keep your equipment running effectively
and economically.
To increase heat transfer
efficiency, lower maintenance
cost, conserve overall energy
consumption and thus
enhance the usable life of
your machinery, removing
scales in all your water-
cooled or water-heated
rubber and tyre equipment
is very important.
