Despite the long history of successful slurry pumping operations covering a wide range of slurries, limited published data is available to estimate Hf accurately, for every possible duty. A high degree of accuracy is normally required only if Hf represents a high proportion of the Total Dynamic Head, H, for a proposed application so that large errors in estimating Hf would be reflected in correspondingly large errors in estimating H. Continue reading “SLURRY FRICTION HEAD LOSSES IN PIPELINES”



The main components of Total Dynamic Head are:

a) Total Discharge Head, and

b) Total Suction Head.

The equation is:

Total Dynamic Head = Total Discharge Head – Total Suction Head

Algebraically, H = (Hd) – (Hs) (m)

or, H = (Hgd + Hvd) – (Hgs + Hvs) (m)

The values Hvd and Hvs are always positive (+ve)

Hd is usually positive (+ve), (above pump centreline)

Hs may be positive (+ve), (above pump centreline) or negative (-ve), (below pump centreline).

When Hs is positive (+ve): H = (Hd) – (Hs) ie: H = Hd – Hs

When Hs is negative (-ve): H = (Hd) – (Hs) ie: H = Hd + Hs

a) Total Discharge Head, Hd

Basic Simple Formula: Hd = Zd + Hfd + Hve (m)

Zd may be positive (+ve) or negative (-ve)

If applicable, additional terms must be included in the formula to account for increased value of Hd, due to any contractions (for example, nozzle friction loss) and enlargements; friction loss in a flow-measuring device and exit into pressure-fed equipment, for example, a hydraulic cyclone.

b) Total Suction Head, Hs

Basic Simple Formula: (Hs) = (Zs) – Hi – Hfs (m)

(Hs) and (Zs) may each be positive, (+ve) or negative (-ve).

If applicable, additional or substitute terms must be included in the formula to account for increased or decreased values of Hs due to any contractions, enlargements, flow measuring device. These are as follows:

  1. liquid supply surface being under pressure, Hpr, or under vacuum, Hvac;
  2. ii) differential column head loss, Zc, and
  3. iii) substitution of effective mixture static suction head Zsm in lieu of Zs.

NOTE: Values of Hs are directly applicable in NPSHa calculations and in selection of shaft-sealing arrangements.

The term “Total Dynamic Head” correctly describes the driving force developed by a centrifugal pump, regardless of the Specific Gravity of the liquid or slurry pumped. The head (+ve) or (-ve) at any point in the system may be converted to pressure or vacuum, respectively, by the application of conversion formulae.

Total Dynamic Head, H, is the head which is required by a given system to maintain a given flow rate, Q, through the system.

H varies as the flow rate through the system, Q, varies. The relationship of H with Q is known as the System Resistance and may be expressed algebraically or graphically.

a) Total Dynamic Head: With Positive (+ve) Suction Head

Figure A4-1 illustrates a pump discharging a flow rate, Q, with discharge and suction gauge pressure heads, both relative to atmosphere and both corrected to pump centreline, measured at the pumps discharge flange and at the pump suction flange, respectively. All heads are expressed in metres of actual mixture being pumped.

The Total Dynamic Head, H, required to maintain flow rate Q through the system is the algebraic difference between the Total Discharge Head and the Total Suction Head.

H = Hd – (Hs)

= (Hgd + Hvd) – (Hgs + Hvs)


These velocities represent the actual values for average velocity at the pump discharge flange (Vd), and at the pump suction flange (Vs), respectively.



b) Total Dynamic Head: With Negative (-ve) Suction Head

When Hs is negative (-ve) that is, a vacuum head is indicated by the gauge, as in Figure A4-2, the substitution of the negative value in the formula serves to positively increase the value of H with respect to Hd



As H = (Hd) – (Hs) and as the suction and discharge pipes are often of different internal diameter, it is advisable to estimate values of Hd and Hs separately. The formulae used should be the Basic Simple Formulae, but amended where necessary to allow for any additional or substitute terms specific to the proposed duty as follows:

a) Total Discharge Head: Hd

Basic Simple Formula: Hd = (Zd) + Hfd + Hve

Typical possible additional terms are as follows:

i) Head Loss on conical enlargement (see Figure A4-4);

ii) Head Loss on contraction (see Figure A4-4);

iii) Head Loss on Exit into Pressure-Fed Equipment (refer to Head Loss at Exit into Pressure-Fed Equipment).

b) Total Discharge Head: Hs

Basic Simple Formula: Hs = (Zs) + Hi + Hfs

Typical possible additional terms are as follows:

i) Head GAIN in supply from Pressure Vessel, Hpr;

ii) Head Loss in supply from Vacuum Vessel, Hvac

iii) Head Loss on Differential Column (applicable in dredge applications, Zc – refer to Differential Column Head Loss)

a) Pipeline Friction Head Loss, Hf

The friction head loss in a given pipeline is estimated for the Total Equivalent Length of Pipe, L(m), which is the sum of the Total Actual Length of Pipe, La(m) and the Aggregate of Equivalent Lengths for all valves, bends and like fittings, Lf(m) (see Figure A4-3) contributing to friction head loss in the pipeline.



Generally L = La + Lf.


i) For Suction Side: Ls = Las + Lfs (Friction Head Loss = Hfs)

ii) For Discharge Side: Ld = Lad + Lfd (Friction Head Loss = Hfd)

Values of Hfs and Hfd should be estimated separately, for example, during the preparation of the respective separate sets of calculations leading to the estimates of Hs and Hd. By separately estimating Hs, its value is readily available for use in NPSHa CALCULATIONS, (refer to APPENDIX 6 – NET POSITIVE SUCTION HEAD (NPSH)), and in the selection of Shaft-Sealing arrangements (refer to Shaft Sealing).

b) Inlet Head Loss, Hi: Exit Velocity Head Loss, Hve

Separate provision is always made in the standard formulae for the terms:

i) Hi, the Inlet Head Loss (Suction side only), and

ii) Hve, the Exit Velocity Head Loss (Discharge side only).

That is, the terms Hi and Hve are included in the standard formulae for Hs and Hd respectively.

c) Head Losses due to Contractions and Enlargements

These additional head losses are calculated by use of the formulae provided in Figure A4-4. As no separate provisions are made in the standard Hs and Hd formulae for individual symbols or terms anticipating these friction head losses, any such estimated head losses, if applicable, should properly be added to the values calculated for Hfs or Hfd respectively.

Friction losses in jet nozzles (Hn) may be treated as for conical contractions unless more reliable head loss data is available.



d) Sundry Additional Causes of Effects on Hfs or Hfd

The calculated values for Hfs and Hfd must be corrected to allow for permanent friction head losses when any in-line restrictions, such as flowmeasuring devices, are intended to be installed (for example, quarter-circle orifice plates).

e) Differential Column Head Loss

Figure A4-5 depicts a mixture of Specific Gravity, Sm, flowing upwards and drawn from a supply of settled solids and overlying liquid, Sl. As the liquid of the same vertical height, Zl. The resulting effective static head loss is known as the differential Column Head loss, Zc:


Sm is greater than Sl, the vertical height Zl, of mixture in the submerged portion of the suction pipe is not completely balanced by the surrounding

Where this condition exists, Zc must be included as an additional head loss in the pipe system. This would effect both total head and NPSHa (refer to APPENDIX 6 – NET POSITIVE SUCTION HEAD (NPSH)).





Digitalisation opens the door to enhanced plant performance

Depletion of mineral deposits creates a profitability and productivity challenge, forcing industry leaders to develop innovative solutions.

Digitalization itself cannot mine the ores, but digging into data and using new technologies is the opportunity to mine smarter and increase productivity.

E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Process Optimisation\161213-digitalmine.jpg

Take advantage of digitalisation and optimise your mine performance

We are at the brink of a new standard for enhancing productivity in mining operations, and its arrival comes not a second too soon.

With the world’s increasing hunger for minerals alongside resource scarcity, you must dig deeper and in more remote areas to meet this need.

Optimising your process has never been more crucial to the productivity and bottom line of your mining operation.

E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Process Optimisation\Capture10.JPG

The interconnectivity of technologies enabled by Internet as well as data collection and analysis are rapidly developing across the world and across industries. Born from a necessity to improve the mining processes, these technological tools are now ready to benefit the mining industry as well. As of yet, an estimation of only 5% of mining operations make use of the IoT, as well as only a 1% usage of all data collected in the mining industry. Our understanding of for example the resource base then comes from only applying 1% of the knowledge available to us. Imagine the strides we could make if we made use of all the valuable data.E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Process Optimisation\Capture2.JPG

How Internet of Things can optimise your productivity 

The interconnectivity can be used to affect three factors in your mining operation: process optimisation (quality and throughput), maintenance strategies and utility consumption. Understanding the advanced sensing and the data analytics allows plant managers to make good decisions about balancing operations. Equipment may need to be pushed harder in order to meet quotas, but can also be slowed down if necessary.

E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Process Optimisation\Capture3.JPG

As an example, you might have a crusher where the sensor data indicates that the mantle has been worn down to a certain level. The system could then adjust the opening and operation of the crusher to maintain the desired particle size, despite the machine being somewhat worn.

Simply put, a process control system can measure and assess a large number of parameters and their interdependencies within mere seconds, far superior to anything that could be done manually. Adjustments and optimisations done in real time allows for the increase in production, lower energy consumption, reduced wear and tear to name a few. The system also allows for predictive maintenance, meaning you can avoid unexpected downtime and maintenance costs. If implemented properly, the whole mining operation can be optimised creating a big potential for you and your bottom line.

Data – the resource with the highest potential? 

If it does not already, proper data analysis will play a crucial role for your mining operation and its productivity in the future. With increasing resource demands, as well as scarcity of minerals, players in the mining industry are forced to adopt new solutions, if they wish to survive and continue to meet demands. Digital innovations, providing knowledge about everything from the resource base to real-time performance of equipment, will increase your productivity.

An example of how to reap the benefits of data analysis is the PlantLine™ Service Agreement, which is a partnership between you as our customer and us. With the agreement, plant performance is proactively optimised through remote, continuous monitoring and adjustments to various parameters on the equipment.

E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Process Optimisation\Capture12.JPG

PlantLine is a combination of online support, on site support and training of personnel. Issues can be resolved quickly and for the most part remotely. If a solution requires on site support, the problem can almost always be diagnosed online, meaning shorter wait times for a person to show up with the right equipment.

At FLSmidth, we work hard to lead this technological innovation and constantly seek new ways to enhance your productivity through digitalisation of equipment across the flow-sheet. Together, we can create the most possible value from digitalisation and your mining operations.

Improving flotation efficiency, Innovation in flotation

You need to make sure that your design criteria meet the specific demands of your mine. Yet, bottlenecks still occur, and undersized dewatering circuits are extremely unforgiving. So how can you make a flotation device more efficient without making it consume more energy? Our flotation team was pretty sure that they could improve the energy efficiency of flotation by rethinking the rotor/stator technology. It just required a change in the hydrodynamics of the flotation system.E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Upgrade Process Automation\Capture1.JPG

Reduce energy consumption, improve performance 

The answer they came up with was the nextSTEP™ rotor/stator. But the longer story about how that technology was developed shows how cooperation across industries and academia can help save energy and improve productivity in your mine.

A step change in both metallurgical performance and energy efficiency

The nextSTEP™ Rotor is designed to produce ideal flow streams. It also produces strong enough turbulence to enhance bubble-particle attachment. This improves recovery rates and concentration grades while lowering energy requirements.

Improved performance

FLSmidth is the world’s largest supplier of flotation equipment offering lower energy consumption, improved recovery and increased operational efficiency.

For the initial technology developmental phase, we teamed up with aerospace researchers, surface chemistry researchers and the Center for Advanced Separation Technologies at Virginia Tech. The combination of mining industry academics and experts from the aerospace industry allowed the team to come up with an innovative design concept for the rotor/stator.

Smaller bubbles have better attachment properties than large ones. But if you increase the rate to improve throughput, the flotation cells produce larger, not smaller bubbles. So it’s really not a straightforward proposition.

The aim was to design a machine that enabled an increase in the the air volume and a reduction in the bubble size at the same time, while optimising the energy dissipation rate.

E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Improving Flotation Effeciency\Capture20.JPG

Saving energy and improving performance

The target was to create a new ultra low-energy flotation system. The team succeeded to the extent that the nextSTEP™ rotor/stator reduces your power requirements by 15-40 percent and has the lowest operating power of any forced-air flotation mechanism on the market.

E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Upgrade Process Automation\Capture7.JPG

To create an environment for the bubbles and particles to make contact with the least amount of power possible, the vane of the rotor was elongated and slots were cut in the stator to optimise the geometry of the rotor/stator assembly.

The design also improves your performance. The new rotor produces ideal flow streams and an energy dissipation rate that enhances the bubble-particle attachment. The patented rotor/stator makes energy dissipation more uniform which results in a higher probability of bubble to particle contact during the flotation process. This dramatically improves your attachment rates.

Froth Recovery Upgrade Package

Improve metallurgical performance with advanced froth phase control

Enjoy superior froth-level control and metallurgical performance, with the FLSmidth Froth Recovery Package. Take your flotation cell to the next level with actuators, level sensors and radial froth crowders designed to provide improved recovery and grade.

E:\MINECO\WEBSITE_MINECO\6_ENGINEERING SERVICES_02 pages\Upgrade Process Automation\Capture10.JPG

Get the most out of froth recovery with our Froth Recovery Package

Often, before you can put your valuable ore to good use for your business, you need to separate it out from the waste material. And in many cases, the answer is froth flotation. However, froth flotation is not an exact science, and small-yet-numerous particles of valuable ore may be getting thrown out with the tails. These can add up, accounting for a significant loss in potential revenue. Our Froth Recovery Package offers a solution that not only improves froth recovery, but also saves overall costs.

The Froth Recovery Package enables you to better control the froth phase, which in turn improves the performance of the flotation cell. The addition of the radial froth crowders adds a new dimension to the control strategy. It allows you to shift the grade recovery curve by allowing either deeper froth or faster froth removal.

Power Transmission products refers to various components that allow for internal parts to operate properly in machinery. These items typically include: belts, chains, couplings, pulleys, sprockets, bushings, hubs, bearings, linear actuators, slide rails, bevel gears, worm gears, and various other components.


A shaft coupling is used to join two shafts together and to ensure that the two shafts rotate together

Rigid couplings connect well-aligned shafts, while flexible shaft couplings are used to cancel out the misalignment between two shafts.

These components can also be used to absorb or reduce shock and vibrations. Some of the many different kinds of couplings include bellows couplings, flywheel couplings, jaw couplings, universal joints, fluid couplings, and torque limiters. Couplings are commonly used in power transmissions, generators, wheels, pumps, and turbines.

Essentially, a gearmotor is a pairing of gear reducer and ac or dc electrical motor. The gear and the motors are combined into one unit.

A gearmotor delivers high torque at low horsepower or low speed. The speed specifications for these motors are normal speed and stall-speed torque. These motors use gears, typically assembled as a gearbox, to reduce speed, which makes more torque available.

Gearmotors are most often used in applications that need a lot of force to move heavy objects.

E:\MINECO\WEBSITE_MINECO\5_POWER INDUSTRY_08 pages\Tranmission equipment-01page\Siemens-Gearmotors-SIMOGEAR-efficiency-example-1024x739.jpg


Speed reducers are used to redirect the output of a high-speed motor to another component at a lower speed.

Gears within the speed reducer provide the mechanism for reducing the output speed of the motor.

The size ratio of the input gear to the output gear is directly related to the speed reduction, so different sized gears can be used to achieve different speeds.

Speed reducers are know by many names and come in a variety of configurations. These include cyclo reducers, gear reducers, gearboxes, right angle gear boxes, and planetary gearboxes.
