From quarry to finished product
Crushed stone 5–25 mm goes through the following stages on its way from the quarry to the customer.
Stage 1
Drilling and blasting
Rock at the quarry is loosened by drilling and blasting, using two modern drilling rigs purchased by Uzbekistan Railways JSC.
Stage 2
Excavation and haulage
The blasted rock is loaded by excavators and hauled by dump trucks to the crushing and screening plant.
Stage 3
Primary crushing
Raw rock is fed into a jaw crusher and broken into large pieces.
Stage 4
Secondary crushing
A cone crusher reduces the stone to fine fractions and evens out the grain shape.
Stage 5
Screening
Screens grade the crushed stone into fractions from 25×60 down to 5×10.
Stage 6
Laboratory control
In the company's testing laboratory the density, strength and grading of every batch are tested to GOST standards.
Stage 7
Loading and delivery
Finished product is loaded into dump trucks by front-end loaders and delivered to the agreed address.
