Raw Meal fineness x kiln output Page 1 of 3
Re: Raw Meal fineness x kiln output. Hello Rodrigo, Raw meal fineness directly influences product quality rather than production rate. However if raw meal finess is excessively coarse, or excessively fine, it can indirectly effect production rate.. Very coarse raw meal, especially containing substantial amounts of coarse quartz (>40 microns) and coarse calcite (>100 microns) will invariably

Manufacturing process Lafarge in Kenya Cement
The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
