Roots Blowers have been a common utility in cement plants for a very long time now. Whenever a large volume of air is to be used at constant pressure, a Roots Blower is the right equipment.
India is the second largest producer of cement in the world. Further, in order to develop infrastructure projects, cement demand is going to see an upward trend. Some of the major initiatives taken by the government such as development of Smart Cities are expected to give a substantial boost to the cement sector.

A cement manufacturing plant consists of many stages and various cycles are involved. Roots Blowers (Twin/Tri Lobe Roots Blower also called Rotary Lobe Compressors) are widely used and installed in some of the important stages in cement manufacturing plants. Some of the common applications where these Blowers are used are kiln burner feeding, pre-calciner, burner Feeding, raw meal silo feed Aeropol, silo mixing bin aeration and surge bin aeration, to name a few. The quality of these Roots Blowers should be excellent so that they work in the critical conditions of a cement manufacturing plant.

Acme Air Equipments Company Pvt. Ltd., an ISO 9001-2008 certified company, manufactures high quality Roots Blowers, Vacuum Pumps, Vacuum Boosters and Pneumatic Conveying Systems like Cement/Fly Ash Conveying System, Dust Collection System and Catalyst Unloading System. The company has been manufacturing Roots Blowers since 1990 and has been supplying to some of the leading and quality cement manufacturers in India.

Charging of kiln is one of the critical stages where Roots Blowers are used. These Blowers take normal atmospheric air at suction and compress it to the required capacity and the required pressure at discharge and supply it, so as to charge the kiln for the next process. Roots Blowers are also used to convey cement and fly ash in a cement manufacturing plant. This process of conveying cement and fly ash is done pneumatically by using Roots Blowers.

A common application in cement plants is Roots Blowers installed for Kiln Feed Air Lift Pumps and Raw Mill Air Lift Pumps. We have executed installation of Roots Blower for this application requiring capacity of 8285 CMH and 0.6 kg/cm-? discharge pressure. Suction pressure being atmospheric, the design of Roots Blower is done considering differential pressure of 0.6 kg/cm-?.

Initially, the speed of Roots Blower is determined, which works out to be 1020 RPM and accordingly shaft power of Roots Blower will be 191.7 KW. The shown design is for a Twin Lobe type Roots Blower which is basically a positive displacement blower. Generally, no compression takes place inside of the Roots Blower and thus there is practically no change in the volume of the air delivered at the discharge end. Selecting the correct blower model for such critical applications in a cement plant is the responsibility of the manufacturer. A quality product will always help in attaining overall optimum performance of the plant.

Fornnax Technology Pvt. Ltd. has been honoured with the Special Export Award – Rubber Machinery for 2025–26 by the All-India Rubber Industries Association (AIRIA), in recognition of its highest exports of tyre recycling plants to the European region.

With more than a decade of experience in India’s tyre recycling industry, Fornnax has contributed to the development of advanced recycling technologies and infrastructure. The company currently holds a 90% market share in India’s domestic tyre recycling sector, while exports account for 30% of its business, spanning markets such as Europe, Australia and the GCC.

The award marks another milestone for Fornnax, whose tyre recycling lines and advanced shredding technologies are supporting the growth of the circular economy in India and international markets.

Commenting on the recognition, Mr. Jignesh Kundaria, Founder and Director of Fornnax, said:

“This honour from AIRIA is a reflection of an incredible journey we have undertaken over the years. When we started Fornnax, there was no established recycling industry in India to follow. We chose to build for the future instead. Today, when you see India’s tyre recycling sector, it has already transformed into a dynamic, high-growth industry and we are extremely proud to have played our part in building it.”

Unlike standalone equipment suppliers, Fornnax focuses on developing complete, high-capacity recycling infrastructure. Its integrated systems combine multiple stages of shredding and size reduction to enable efficient, continuous operations. This system-level engineering approach helps recycling operators improve throughput, equipment reliability and operational consistency.

The recognition reinforces Fornnax’s commitment to developing engineering technologies that contribute to a more efficient and circular recycling ecosystem.

Looking ahead, the company aims to expand its international presence while continuing to develop advanced shredding and recycling solutions to address the growing volumes and evolving requirements of the global recycling industry.
