NA RMC batching plant and cement silos at Darakahara
The Darakahara Plant · N.H.31

From stockpile to
site, in one yard.

Eight steps separate a stockpile of our own crushed aggregate from concrete discharging on your site. All eight happen inside our own gate at Darakahara, Kamrup (R) — nothing is subcontracted.

Third-Party Steps
Walk the yard

Eight stages, in the order your concrete moves through them.

Stage 01

Covered aggregate stockyard

Graded stone and sand arrive from NA Stone Crusher and Screening Plant and are stockpiled by size under a covered bay, so rain never changes the moisture content we batch against. A backhoe loader feeds the bins from the pile.

Stage 02

Feed hopper & belt conveyor

Aggregate is loaded into the feed hopper and carried up an enclosed belt conveyor into the plant's weigh bins. The enclosure keeps material dry and dust down on the way up.

Stage 03

Admixture & water dosing

Admixture drums and water sit at the foot of the conveyor, dosed into the mix by the plant's controller rather than by hand — so workability and water-cement ratio hold from the first batch of the day to the last.

Stage 04

Cement silos

Premium TOPCEM and UltraTech cement is stored in our silos — 100 MT (72 m³) of capacity — and screw-conveyed straight into the mixer. Sealed storage means no bag handling, no moisture pickup, and no pause between batches.

Stage 05

Schwing Stetter M1T batching

The M1T weighs every constituent to the mix design and mixes one cubic metre a minute. Batching is computerised, so the M25 you order in March is the same M25 you order in November.

Stage 06

Charging the transit mixer

The mixer pulls in under the discharge chute and takes its load in a single charge. Seven mixers rotate through the bay, which is what lets us hold a pour schedule instead of a rough delivery window.

Stage 07

Weighbridge & site office

Loaded mixers cross our own 100 MT weighbridge — 16 m × 3 m — before leaving the gate. The weighbridge, site office and laboratory share one building, so weighment, docket and cube sampling all happen at the same desk.

Stage 08

Cube sampling & curing

Cubes are cast from the batch, marked with the party name and date, and cured in our temperature-maintained vat until their 7 and 28-day tests. Every cube in the vat belongs to a specific client's pour — that is your strength record, on request.
