Welcome To Maroon Engineers & Consultant Pvt Ltd, We Are Professional & Established Company.
Iron ore is the main source of iron and steel and our world is made of it. The computers we use, the chairs we are sitting on, the cars we are driving with, the buildings we are working in, the schools, we are learning in and the cell phones we are communicating with – everything contains iron ore. Iron ore is so present in our everyday lives that it is practically impossible to imagine a world without this mineral resource.
All modern methods of energy generation and transmitting consist of iron and steel. Thus, we cannot renounce iron ore mineral processing, even though iron and steelmaking sector is one of the largest energy consumers in the world. It is our duty to improve the iron ore beneficiation in order to implement sustainable solutions to minimize CO2 emissions and to improve resource efficiency by better process and product performance.
As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions by passing it over sieves through which undersized material falls. In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres). If the lump ore is of the appropriate quality,
Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick to larger ones, and then the appropriate amount of coke is added. Initially, coke on the upper surface of the bed is ignited when the mixture passes under burners in an ignition hood.
