4.3 Manufacturing Process

The manufacturing process of fibre cement product is based on classical wet Hatschek process

where in the Chrysotile Asbestos Fibre, Pulp is mixed with Portland Cement and Fly Ash in

aqueous condition.

The raw materials that are used in the manufacture of asbestos cement products are Chrysotile

Asbestos Fibre, Ordinary Portland Cement, Fly ash, Pulp & Hard Ground Waste of broken and

solid wastes.

The entire Chrysotile Asbestos Fibre requirement is imported and received in ships at Cochin

Port. Fibres are available in impervious HDPE bags of 50 / 40 kgs each in palletised form.

Pallets from the trucks are unloaded, stored in the fibre storage godown and subsequently

transferred to raw material preparation section.

___________________________________________________________________________


Chrysotile Asbestos fibre packed in HDPE bags and shrunk wrapped on pallets is mechanically

lifted and fed into a fully automatic bag opener where the bags are slit open and the contents

fed into a Fibre Blender. The empty fibre bags are automatically conveyed into bag shredder

and through Cyclone and Screw conveyor the shredded bags are fed into the Fibre Mill and

consumed along with the fibre.

In the Fibre Blender, different grades of fibre in compressed form are broken down into

smaller lumps and blended homogenously. Fixed quantity of water is sprayed to arrest dust

generation. Blending is done for a fixed duration. Thereafter, the contents of the blender are

discharged into the Fibre Mill. During the process of grinding in the Mill, fixed quantity of

water is sprayed to facilitate fibrisation and arrest dust generation.

The milled moist fibre is conveyed by a Screw Conveyor and stored in a buffer Silo mounted

on load cells with Screw Conveyor at the bottom.

From the buffer silo, the ground fibre is fed to the Fibre Mixer where it is stirred with water to

open up the fibre.

At Hydro Pulper pulp slurry is prepared and added to the Main Mixer.

Cement, flyash and hard ground waste are mixed with water in cement mixer to form a slurry.

Then this slurry is fed to the Main Mixer where already slurry mix of fibre and

pulp is present. Main Mixer agitates the slurry for homogenous mixing. This slurry is

discharged into the Agitator Tank prior to transferring in the sheeting machine.

Batching of various Raw Materials is done automatically through a high precision Batch

control system along with PLC.

Sheeting machine consists of vats for containing the slurry. Cylindrical sieves rotating in vats

for filtration, endless felt for picking up the solids as a layer, vacuum chambers for de-watering

with the help of vacuum Pumps and a metal cylinder called bole for collecting the layers.

The wet sheet formed on the bole is cut-off after required thickness is achieved. The wet sheet

is taken on to take off conveyor.

___________________________________________________________________________


The wet sheet after stamping is transferred to another belt conveyor called ‘Holding Conveyor’

for finishing operations. When the wet sheet is positioned directly under the Corrugating

Machine, the motion of the conveyor is stopped. Sizing and profile corrugating is carried out

by the corrugating machine.

The sheets are stripped off from the templates with the help of Depiling Machine and moved to

maturing section for horizontal maturing.

Manufacturing of Moulded Goods and Accessories are carried out in MG department. All these

are made out of wet sheets produced by the sheeting machine. The wet sheet cut to size is

placed on the mould for making required articles. The article is allowed to remain in the mould

for a period of 8 to 24 hours depending on the thickness and nature of articles and stripped off

from the mould after attaining the initial strength and then sent for maturing.

(c) Process Description

The raw sewage from the domestic operation is taken to the collection cum equalization tank I

& II. Then it is pumped to the aeration tank.

The Aeration tank provided with 24 hours detention time. An Air Blower is provided with 3

HP capacity to supply oxygen in the form of fine air droplets into the Aeration Tank for

reducing BOD.

___________________________________________________________________________


Mixed Liquor Suspended Solids (MLSS) level in the aeration tank will be maintained in the

range of 3000-4000 mg/l and a sludge age of 15-20 days is maintained by the regulation of

return sludge. The blower should run for nearly 24 hours per day. Nutrients like urea and

D.A.P. is to be added regularly in the aeration tank.

The overflow from the aeration tank is passed to a settling tank for separation of bio-sludge

and the settled bio-sludge is re-circulated to the aeration tank to maintain the MLSS level in

the desired range (30%). If MLSS is more than 4600 mg/l the excess bio sludge from settling

tank is pumped to the Sludge digestion tank.

The clear overflow from the settling tank is filtration tank. The outlet from the filtration tank is

collected by the final collection tank.

From this collection tank, the sewage is pumped to Dual Media Filter for removal of very fine

suspended solids, odour and turbidity. The outlet from Duel Media Filter will meet out the

standards prescribed by TNPCB and it is used for greenbelt development.

buffer zone has no forests and the agricultural land constitute 28%, which is mostly

unirrigated.

6.7 Socio-Economic Conditions

There is no habitation or settlement in the industrial area. The nearest village of Kurichi is

having a population of 125,800 with 63,033 males and 62,767 females as per 2011 census data.

The workers constitute 35%. The major source of income of the local population is from these

types of Industries only.

___________________________________________________________________________


7.0 ENVIRONMENTAL IMPACT ANALYSIS

7.1 Air Quality

The emission from the all the sources will be dispersed through bag house with adequate

height of stack has been provided. The DG Set will be operated only during power failure. So

the emission from the Dg Set will be dispersed through adequate height or stack. Hence the

impact of operating the DG Set on the ambient air quality will be minimal.

7.2 Water Resource

This expansion unit is depending on ground water drawn through Bore Well for its different

water requirements. The unit currently consumes 164 KLD of raw water for its process and

non-process uses. After expansion the water requirement will be 276 KLD.

7.3 Waste Water

The waste water from the domestic uses is sent directly to the septic tank with soak pit and

Sewage Treatment Plant and treated sewage will be utilized for green belt development inside

the factory premises. Hence the impact from the waste water will be nil.

7.4 Solid Waste Management

The solid waste will be generated from the unit Asbestos containing waste (144 T/Year) and it

will be collected, stored and reused in the process. Sludge from STP (7.5 KG/Month) will be

collected and used as manure.

7.5 Land Degradation

Since, the small quantity of wastewater will be generated from domestic usages, the chances of

contamination of soil will be nil. The vacant area in the industry will be used for tree plantation

to improve the surrounding environment of the industry.
