A batching plant combines ingredients like water, cement, aggregates, and admixtures to produce concrete. There are two main types: dry batching plants, which need to be used with concrete mixer trucks, and wet batching plants, which can mix concrete on their own. The batching process involves weighing the ingredients on a mass basis for accuracy. Batching plants can be portable, stationary, or semi-portable. Modern plants use computer automation to measure ingredients accurately. Dust and water pollution are concerns that require mitigation measures like dust collection systems. Key components include bins, conveyors, scales, silos, and dispensing systems.

3. BATCHING
PLANT
A concrete plant, also known as a batch
plant or batching plant or a concrete
batching plant, is equipment that combines
various ingredients to form concrete .
Some of these inputs includes
water, air, admixtures, sand, aggregates
(rocks, gravel, etc.), fly ash, silica
fume, slag, and cement.

4. TYPES OF BATCHING
PLANT
• Dry mix plant
• Wet mix plant

5. Dry
Batching
Plant
Dry type concrete
batching plant
needs to cooperate
with concrete mixer
truck, only this can
it produce concrete
for construction
project.

6. Wet Bathing
Plant
Wet concrete plant can
produce concrete on
its own, because it has
twin shaft paddle mixer
as the mixing console.

7. Batching Process:-
1.}Volumetric batching .
 Not desirable except for small non engineered jobs
‰
2.}Weigh Batching (Mass basis, IS456:2000)

8. Volumetric Batching:-
-Batching by mass (weights) as reproducibility of loose volume is inadequate
and is not economical .
Batching Process:-
-Control and storage of materials Aggregate bins for storing aggregate. Silos for storing
cement and cementitious materials.

9. Mobile
concrete
batching plant
Batch plants can be portable, stationary, or semi-
portable. Certain batch plant designs may be
considered mobile, but not necessarily easy to
set up and tear down.
These categories typically differ in the ease of
startup and teardown and the presence of
portable features such as axles, brakes, and
lights. Mobile batching plants are typically a
single unit, made up of a cement silo, an
aggregate bin, an aggregate conveyor and the
cement and aggregate batchers, but at higher
hourly production capacities may require
numerous loads for a single plant. Typically, a
mobile batching plant can be dismantled and
reassembled in a few days time.

10. Automation
and control
Modern concrete batch plants (both
Wet mix and Dry mix) employ
computer aided control to assist in
fast and accurate measurement of
input constituents or ingredients.
With concrete performance so
dependent on accurate water
measurement, systems often use
digital scales for cementitious
materials and aggregates, and
moisture probes to measure
aggregate water content as it enters
the aggregate batcher to
automatically compensate for the
mix design water/cement ratio
target.

11. Dust and water
pollution
Municipalities, especially in urban or
residential areas, have been
concerned at the pollution by
concrete batching plants. The
absence of suitable dust collection
and filter systems in cement silos or
at the truck loading point is the major
source of particulate matter emission
in the air. The loading point is a large
emission point for dust pollution, so
many concrete producers utilize
central dust collectors to contain this
dust.

12. Components of a
Batching Plant:-
–A) Aggregate bins for various types of
aggregates.
– B) Feeding mechanisms such as
scrappers, conveyors or hoists etc. to
transfer aggregate to scales (balances).
– C) Balance and measuring system.
–D) Cement silos and a conveyor screw or
bucket conveyor .
– E) The storage tank for water and water
measuring system .
– F) Dispenser for chemical (liquid)
admixture.

13. Diagram of Batching Plant:-

16. BATCHING:-
– Plant Type can be cyclic or continuous.
– Plant Type can be automatic or manual
– Accuracy:
Recommendation of IS 456 is ±2% for the
quantity of cement measured and ±3% for
the quantity of aggregate, water and
admixture being measured.

17. Plant Capacity:-
– Capacity depends on
1) size of the job;
2) required production rate; and
3) required standard of batching
performance.
*Capacity of the material handling system,
bin size, batcher size and; mixture size
and number controls the capacity
