Cement Plants

From the raw meal silo to the cooler — every choke point in the line, cleared from outside the shell.

Cement is where we do most of our work, and where the cost of a blockage is easiest to calculate: a preheater choke or a kiln ring stops the line, and every hour it stays stopped is production you cannot make up.

Where we work in your plant

Area	What we clear
Preheater tower	Cyclone jams and chokes, stage build-up — at operating temperature
Kiln inlet & riser ducts	The classic choke points, in hours rather than days of chipping
Rotary kiln	Ring build-up in the burning zone, without cooling the kiln
Precalciner & cooler	Snowmen and accumulations removed from outside
Feed pipes & inlet chambers	Choked pipework cleared without dismantling it
Silos	Cement, clinker, raw meal & blending, gypsum, fly ash
Extraction & conveying	Gates, chutes, air slides and conveying line blockages

Why plants call us instead of clearing it manually

Manual ring removal means shutting the kiln, waiting for it to cool, and putting a gang inside — up to 8 days and as many as 30 workers. The Cardox CO₂ System works at full operating temperature with one or two operators, so the cool-down and heat-up disappear.

Where sockets are fitted permanently to the vessel wall, blockages clear during production — no outage to schedule at all.

We work for ten of India's largest cement producers — UltraTech, ACC, Ambuja, Dalmia, Shree, Ramco, JK, India Cements, Heidelberg and Chettinad — 55+ plants and 500+ vessels over 30+ years.

Where the line chokes

Ten places we are called to, on every cement line

Cement production has no shortage of places prone to rings, chokes and build-ups. Every point marked below is cleared from outside the shell, at operating temperature — no cool-down, no entry.

1 Cyclone stages
Material bakes onto the cone and the vessel walls. Cleared through wall sockets without waiting for the tower to cool.
2 Cyclone cones & dip tubes
The classic choke point. A tube fired through a socket breaks the build-up in milliseconds.
3 Lower-stage cyclones
Hotter, stickier material and the heaviest coating in the tower.
4 Feed pipes
Choked pipework between stages cleared without dismantling it.
5 Bottom stage & riser duct
Where meal is hottest and most prone to bonding on its way to the kiln.
6 Kiln inlet chamber
Accumulations at the inlet, cleared from outside the shell while the line stays hot.
7 Rotary kiln — ring build-up
Rings in the burning zone broken out without cooling the kiln or sending anyone in.
8 Cooler & snowmen
Build-up and snowmen in the cooler section removed safely from outside.
9 Clinker extraction
Blocked outlets, gates and chutes opened without a person entering.
10 Clinker & cement silos
Wall coating, ratholes and deadstock — full storage capacity restored.
