Fly ash bricks and semi-automatic machines: the future of eco-friendly and sustainable construction

At present, the use of environmentally friendly and sustainable materials in the construction industry is increasing day by day. In the past, red bricks were the mainstay, but in the modern era, fly ash bricks have emerged as an alternative, which are made from industrial waste called fly ash from thermal power plants. It not only reduces environmental damage, but is also stronger and longer-lasting than red brick. 

Fly ash bricks are commonly manufactured from fly ash blended with sand or stone dust, along with cement or lime and a little water. These materials are mixed in a mixer and pressed through a mould in a hydraulic press machine to make bricks. The brick is then dried and hardened with carbonation over a period of time. The whole process does not require any kind of burning or high heat application, so it is considered to be a cold process based construction material.

The most widely used technology in the production of fly ash bricks in the present era is the PLC controlled semi-automatic machine. One of the features of this machine is that it is operated with a programmable control system. It does not require a more skilled operator to operate the machine. Only when the program is set, the machine automatically mixes, presses and makes bricks in the prescribed proportions. It makes the production accurate, fast and stable.

PLC controlled semi-automatic machine greatly reduces the labour cost. Because here many things are done automatically, such as raw material mixing, brick moulding, brick ejection, etc. As a result, it is possible to complete the work with fewer workers at each step. At the same time, the cost of production per unit also decreases as more bricks are produced in a given time. If there is a problem inside the machine, the PLC displays an error message on the display, which can be easily solved and reduces the time of stopping production.

The semi-automatic machine of the new model has an auto batching and mixing system, which helps to mix the materials in the right proportions in each batch. In addition, the auto-ejection and stacker technology removes the brick from the mould and piles it in a specific place on its own. This reduces the physical work of people and at the same time increases the speed of production. It also reduces the chances of worker dependency and accidents.

Fly ash brick machine is environmentally friendly because it does not need to burn wood, coal or gas. It makes bricks in a cold process and does not emit any smoke. Most importantly, the waste material of the power plant is used here, i.e. fly ash, which increases pollution when thrown into nature. In this method waste is converted into resources. Also, the soil of the cultivated land does not have to be cut for making these bricks, thereby saving agricultural land.

Brick is not only environmentally friendly, but also very durable. The pressure tolerance of this brick is much higher, due to which it does not crack or corrode easily. In addition, these bricks absorb less water, which makes the building less prone to dampness. Because of the precision of its measurement, it takes less plaster to build walls and reduces the cost of construction. At the same time, the internal environment of the building remains comfortable as fly ash brick is effective in resisting heat and sound.

At present, there are several companies in Kolkata that are making fly ash brick machines in kolkata with modern technology. Laxmi Narayan Engineering Works is actively working in the industrial areas of Eastern Part of India. They not only sell machines, but also provide installation, training and after-sales service. Laxmi Narayan Engineering Works  manufacturing their own brand machines using international quality parts, which are being supplied to different districts of West Bengal and Eastern India apart from Kolkata. Many people are providing machines in easy installments under MSME schemes and startup ventures, which is very helpful for new entrepreneurs.

Fly ash bricks and these modern semi-automatic machines are becoming one of the components of sustainable construction of the future. To increase the use of environmentally friendly materials in construction, this type of technology needs to be spread further. The government is also encouraging the use of fly ash bricks in various construction projects such as Smart City Mission, PMAY scheme, etc. So for those who want to enter the construction industry or are interested in starting a new venture, the PLC Controlled Semi-Automatic Fly Ash Bricks Machine can be a profitable and future-oriented investment.
