When cement became glamorous, we lost the comfort

Somewhere along the way, we decided that the cement industry needed to become glamorous.

And that, perhaps, was our first mistake. 

Cement was never meant to be glamorous.

It was meant to be reliable, predictable and profitable.

A cement plant was a simple place once.

You had a crusher, raw mill, kiln, cooler, coal mill, cement mill and packing plant.

The job was also simple.

Keep the plant running. Keep the quality right. Keep the cost under control. Go home.

Then came technology.

Digitalisation.

Automation.

AI.

Industry 4.0.

Big Data.

Dashboards.

KPIs.

OEE.

Predictive analytics.

The funny part is that the basic equipment is still sitting there looking almost exactly the same.

A kiln is still a kiln.

A mill is still a mill.

A fan still has to move air.

A bearing still doesn't care whether the plant has Industry 4.0 certification.

And a gearbox still has only one objective: Please don't kill me.

Technology can help. But cement remains M-sensitive.

Cement manufacturing is still heavily M-sensitive.

Man.

Machine.

Material.

Method.

Measurement.

Mother Nature.

Change just one of them and the plant starts behaving differently.

Change two or three together and the plant develops its own personality.

Change all six and congratulations. You are no longer running a cement plant.

You are conducting an orchestra where every musician has decided to play a different song.

That is why two identical plants, with identical equipment, can behave completely differently.

Even two parallel kilns in the same plant can have different personalities.

One says, "I am stable." The other says, "Let's see what happens today."

And both have the same OEM manual.

So, why do we compare everything?

We love KPIs.

TPH.

kWh/t.

kcal/kg clinker.

OEE.

Availability.

Specific power.

Specific heat.

Cost per tonne.

And then we put two plants next to each other and declare one better than the other.

Really?

How do you compare a plant in Rajasthan with one in Meghalaya?

One may have dry limestone. The other may have wet limestone.

One may have favourable ambient conditions. The other may be fighting humidity, rain, material characteristics and logistics.

One may have abundant good-quality coal. The other may be asking the pyro system to perform miracles with whatever fuel arrived on the truck.

And then someone sitting in a conference room says: "Why is your specific heat higher by 15 kcal/kg?"

Because...Mother Nature was not copied in the benchmarking spreadsheet.

The cement plant doesn't need a fashion show.

Of course, technology is useful.

Automation is useful.

Digitalisation is useful.

Advanced instrumentation is useful.

Data is useful.

But technology cannot replace fundamentals.

You cannot digitally transform your way out of a bad bearing.

You cannot use AI to compensate indefinitely for poor housekeeping.

You cannot dashboard your way out of wrong coal.

And no amount of PowerPoint can make a badly maintained fan reliable.

At the end of the day, somebody still has to inspect the equipment.

Somebody has to listen to the sound of a mill.

Somebody has to look at the flame.

Somebody has to check the bearing.

Somebody has to understand why the process has changed.

And somebody has to take responsibility.

That somebody is still Man.

The first "M".

Maybe we should bring back the boring days.

I sometimes miss those good old days.

There were fewer dashboards.

Fewer meetings about meetings.

Fewer colourful graphs.

Fewer acronyms.

The KPI was quite simple.

Is the plant running?

If yes, good.

If no, find out why.

Fix it. Start it. Keep it running. Go home.

And perhaps, most importantly... Make some money.

Because somewhere in our attempt to make the cement industry glamorous, sophisticated and technologically fashionable, we may have forgotten something very basic.

Cement is still a basic industry.

And perhaps the most sophisticated way of running a cement plant is still to understand its basics better than everyone else.

No glamour. No drama. No unnecessary complications.

Just Man, Machine, Material, Method, Measurement and Mother Nature working together.

Keep the plant running. Keep people safe. Make good cement. Control the cost. And go home with a smile.
