FLYASH BRICK MAKING MACHINE

Fly Ash bricks are made of fly ash, lime, gypsum and sand. Fly ash, lime sand and gypsum are manually fed into a pan mixer where water is added in the required proportion for intimate mixing. The proportion of the raw material is generally in the ratio 60-80% of fly ash 10-20% lime, 10% Gypsum and 10% sand, depending upon the quality of raw materials. The mixture is slow setting pozzalona cement mix. After mixing, the mixture is shifted to the hydraulic/mechanical presses. The specially designed machine to give high pressure load at the slow rate in mould designed for customer requirements in the order of 280 to 350 kg/ inch. Holding the pressure at specific time gives the more strength of the finished product. The moulded the bricks then transfer to hydraulic operated wooden pellets manually and store in covered space for three days (minimum) for setting.

Then the bricks taken to yard for water curing for 15 to 20 days. Then it sorted and tested before despatch.

These can be extensively used in all building constructional activities similar to that of common burnt clay bricks. The fly ash bricks are comparatively lighter in weight and stronger than common clay bricks.

Technical particulars of Fly ash bricks

Compression strength	: 60 to 250 kg/Cm Sq.
Water absorption	: 5 to 12 %
Density	: 1.5 gms/cc
Co efficient of softening ( depending upon water consistency factor)

We in Agni Engg . & Industreis in making fly ash brick making machine with semi and fully automatic version with capacity ranges from 1000 to 2000 brick per hour. Fly Ash bricks are made of fly ash, lime, gypsum and sand. These can be extensively used in all building constructional activities similar to that of common burnt clay bricks. The fly ash bricks are comparatively lighter in weight and stronger than common clay bricks. Since fly ash is being accumulated as waste material in large quantity near thermal power plants and creating serious environmental pollution problems, its utilization as main raw material in the manufacture of bricks will not only create ample opportunities for its proper and useful disposal but also help in environmental pollution control to a greater extent in the surrounding areas of power plants.

Fly ash brick has numerous advantages

1.compressive strength is more than conventional clay bricks
2.More resistant to salinity and water than conventional bricks
3.More lighten than conventional bricks
4.Uniform in shape & size and more durable as strength increases with passage of time
5.Less mortar consumption in masonry & saving in plastering cost.

The Process

Fly ash, lime sand and gypsum are manually fed into a pan mixer where water is added in the required proportion for intimate mixing. The proportion of the raw material is generally in the ratio 60-80% of fly ash 10-20% lime, 5 to 10% Gypsum and 10 to 15% sand, depending upon the quality of raw materials. The mixture is slow setting pozzalona cement mix. The process of mixing is same as mixing cement in cement industries where clay and lime stones are burnt with coal, gypsum is mixed and ground to make cement.
The fly ash mix with gypsum and lime powder and ground in a pan mixture gives slow setting cement. Sand is added to bring down the cost of mix of brick and also get finishing of bricks in our process.
After mixing, the mixture is shifted to the hydraulic/mechanical presses. The specially designed machine to give high pressure load at the slow rate in mould designed for customer requirements in the order of 280 to 350 kg/ inch. Holding the pressure at specific time gives the more strength of the finished product. The moulded the bricks then transfer to hydraulic operated wooden pellets manually and store in covered space for three days (minimum) for setting.
Then the bricks taken to yard for water curing for 15 to 20 days. Then it sorted and tested before dispatch

Models

The technology consist of regular mechanical type and hydraulic version.
The hydraulic version is latest and gives higher production output with minimal inputs like in labour and power. The strength of bricks in hydraulic version is better than the others. It gives the pressure of 25 to 50 Ton in lieu of 15 ton in mechanical versions. Embossing the monogram of company on the bricks is easy. Production is high. Continuous operation is possible. The machine consist of following

1.Fly ash Brick making machine, vibrator, hydraulic power pack motor and Control panel

It is hydraulically operated automatic machine. The structure is capable of handling load up to 100 bar. Different size of mould can be fitted with machine. Embossing on brick is easy. It give high production at minimal power loads. Circulated water cooling ensure longer operation.

2.Pan mixing machine with gear box and motor
A mechanical sturdy constructed with heavy rollers to grind the raw materials efficiently. Drive by worm reduction gear box. Easy unloading mechanism with proper door arrangements.

3.Belt conveyer system

A fabricated belt conveyer to take the raw materials of 1.5 tiem more than the capacity of machines. The raw materials can regulated according to the requirements. Rubber with nylon coated belts.

4.Hydraulic pallot trolley

The trolley capable of transporting maximum bricks to stocking area operated hydraulically, which reduce the manpower and cracks of bricks.
