OPERATIONAL/WORKING OF BATCHING PLANT.

 Usually a stationary type concrete batching plant is bigger in size. Its operation is more or less
similar to the mobile version. Stationary version is preferred by customers who want to
product concrete at a single place and portable version is preferred by people who want to
shift sites more often.

 Working principle of concrete batching plant is dependent on five primary functions as below:

 Aggregate feeding – Aggregates and sand have to be fed into the individual feeder bins.
 Powder feeding – Powder here refers to cement, fly ash and additives. These are important
components for binding of material.
 Water – Water will help cement bind evenly with aggregates. Specific quantity of water is
must for any ready mix.
 P a g e | 14

 Storage and conveyance – Storage and conveyance here refer to storage of cement, fly ash,
etc. They have to hold up quantity in bulk and transfer small quantity by screw conveyor to
the weighing hoppers.
 Control system – Control system is very critical for any advanced machine. It makes operation
fast and accurate.

 Concrete batching plant process flow will start from the feeding of aggregates into individual
bins. Size wise aggregates have to be fed into individual bins. These aggregates will be
weighed individually as per the design set in the control panel. After weighing they will be
transferred to the mixing unit. Above the mixing unit there are weigh hoppers for cement,
additive and water. The job of the weigh hopper is to weigh and then transfer the contents
into the following mixing unit . Cement is transferred to the weigh hopper by means of screw
conveyor. Water is pumped up into the weigh hopper. After mixing for a specific time as set in
the mixing unit, the mixer will discharge the contents into transit mixer or a concrete pump.

 All the above processes are carried out carefully and systematically. Each process is carried
out for a specific time frame. The time frame starting from the weighing of aggregates to the
discharge of the ready mix material is known as a batch time.

A. A concrete batch mix  It has a number of parts and accessories that combine and work
plant  together to produce quality concrete. Some of the major
components are as below:

B. Aggregate feeders   Feeding unit is one of the important components. There are bins
located side by side to facilitate feeding of coarse aggregates and
sand. The different number of bins is there which will hold
different sized aggregates / sand into different compartment. The
reason behind putting each material (size wise) into separate bins
is that each material will be weighed separately as per designated
mix ratio.

C. Aggregate weigh  Weigh conveyor usually sits below the aggregate feeders. It is
conveyor . suspended and hanging on load cells. It is to weigh aggregates one
by one and then transfer the same to charging conveyor of skip.
Aggregates are discharged to the weigh conveyor by opening and
closing of pneumatic cylinders.

D. Charging conveyor / Skip   Charging conveyor or a skip is to carry the weighed aggregates to
 P a g e | 17

the mixing unit.

E. Cement weigh scale   Water weigh scale receives water from water pump. It will hold
water and weigh the water as per the recipe set in the control
panel and then add the same into the mixing unit.

F. Water weigh scale   Water weigh scale receives water from water pump. It will hold
water and weigh the water as per the recipe set in the control
panel and then add the same into the mixing unit.

G. Additive weigh scales   Additive weigh scales are suspended on load cells and they will
weigh the additive material prior to dispatch into the mixer.

H. Cement silo / hopper with  – Cement silo is to hold large volumes of cement that comes in
screw conveyor  bulk trucks. It is usually provided with safety accessories. A screw
conveyor of suitable diameter and length is at the bottom enabling
transfer of cement into the cement weigh hopper. Many small
capacity machines are equipped with a cement hopper. The
opening of the hopper is big and it facilitates adding of cement
that comes in bags. Bags have to be placed on top of the hopper
and once they are torn, cement will fall into the hopper. Cement
hoppers are also provided with screw conveyor for transfer of
cement into the weigh hopper. Usually a weigh hopper has 2
openings on top for inlet of 2 screw conveyors.

I. Mixing unit   This is the most critical part and heart of the concrete batch mixing
plant. The job of the mixer is to receive all the ingredients and mix
them thoroughly for a fixed time. Then it will discharge the
contents into a transit mixer or a concrete pump.

J. Air compressor   Air compressor is one of the important components here. It is used
to control all the pneumatic operations of the concrete batch
mixer like opening and closing of cylinders that control the feeder
gates, opening and closing of butterfly valves fitted with weigh
hoppers, opening and closing of the mixing unit gate, etc.

K. Control panel   Control panel will control the working of the machine. Latest
machines are equipped with PLC panel for ease of usage. It is also
possible to save and print mix material recipes in the latest
equipment. Control panel assist in fast and accurate
measurements of the ingredients. With growing demand for high
quality and accurate concrete it becomes important to produce
quality material without any wastage. This is where control panel
helps to control all components of the batching plant.
