Born to be the biggest cement plant in Africa

Obajana cement plant, the biggest cement factory in sub-Saharan Africa, was on Monday commissioned by President Goodluck Jonathan in honour of Aliko Dangote.

Located in Kogi State, Obajana cement is expected to produce about 10 million tonnes of cement per annum.

President Jonathan in his remark, called the plant a “quantum leap” for that nation’s construction sector.

The president noted that the success of this factory was as a result of the government’s policy on public-private partnership.

“To sustain the achievement, government is working with the private sector to launch a Cement Technology Institute, which Aliko Dangote will be the chairman” he said.

The president also revealed that a backward integration policy will soon be implemented for the automobile and garment sectors as well as sugar and rice, “so that by 2016, we not only be producing for our consumption, but also export.”

Mr Aliko Dangote, who was recently crowned, the richest man in Africa by Forbes magazine, in his speech stated that “Nigeria is the best place in the world to invest”, adding that there are immense investment opportunities in the nation’s power and infrastructural sectors.

Invest opportunities abound in various sectors of the economy, such as power, infrastructure, oil and gas. Discerning investments are aware that this is the place to invest and they screaming over each other to come and invest here.

He enjoined the government to replicate similar policies that encourage his cement factory in other sectors of the economy, saying, “if the federal government can improve on policies such as the one that allowed this cement factory, we will be there in no time. “ cement making plant:http://www.crusher-machine.com/cement-production.html

It is estimated that the Dangote group has invested about $6.5billion in the sector in recent years.

Cement production cement mill is one of the most energy intensive production processes. It involves roasting the raw materials and additives to form a clinker, which is then ground into powder in a cement mill. This process requires almost 45 percent of the plant’s total power requirement. The quality of the cement depends on the ground material being as fine and as even as possible. As part of the quality control process, samples are normally taken at regular intervals and analyzed in the laboratory. The operating parameters, i.e. the quantity of fresh material fed in and the sifter rotation speed, are continually controlled in line with the fineness of the grinding stock and the throughput of the returns.

A similar expert system for the processing of copper ores has been developed by Siemens Industry in conjunction with the researchers at Corporate Technology. The system, which has been conceived as an extension of the gearless drive solution Simine Mill GD, also combines a knowledge-based approach with a predictive rule-based system—in this case to optimize water-based grinding processes.

As the professional manufacturer of complete sets of mining machinery, such as impact crusher for sale, Henan Hongxing is always doing the best in products and service.
