The rock fragments are finely ground and combined with other ingredients including clay, chalk, marl, shale, slate, sand, and iron ore. Recycled industrial by-products used to supplement some or all of these components include spent pot liners, slags, and fly, bottom, or incinerator ash.

This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller. The crushed rock is combined with other ingredients such as iron ore or fly ash and ground, mixed, and fed to a cement kiln.

Geometallurgical modeling of the production benches is an attempt to estimate the geometallurgical variables of the different ore domains, which leads to a …

We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
