Hot Mix Plant

An hot mixture plant is an assembly of mechanical and

electronic equipment where aggregates, recycled materials

or other additives are blended, heated, dried and mixed with

binder to produce asphalt mixture meeting specifiedrequirements.

In the batch-type mixing plant, hot aggregate, recycled

materials and binder are added in designated amounts to

make up one batch. After mixing, the asphalt mixture is

discharged from the pug mill in one batch.

RMC(Ready mix concrete) Plant

Ready mix concrete plant is a

centralized factory or batching plant.

concrete is mixed in the plant and then

transported through a truck or trailer tothe construction site.

Concrete with different design mixes are

prepared according to customersrequirement

Plant specifications

The plant was radial bin scraper type.

The capacity was 15m3 per hour.

The concreteproduce per batch was 5m3.
