Jan 01, 2016· The majority of Finland's cement demand is produced at Finnsementti's plants in Pargas and Lappeenranta. The Finnsementti Lappeenranta plant does not have systems for the pre-homogenisation of raw materials. A conveyor delivers raw material from the quarry directly to the raw mill silo. No homogenisation piles are used in the operation.

I. Crush and pre-homogenization Crush. In cement production process, most of raw materials must be crushed, for example, limestone, clay, iron ore, coal, etc. In cement production, limestone is the main raw material whose amount is the largest in all the raw materials. After being mined, usually limestone is in large size and high hardness, it ...
Grinding and homogenization. The grinding process takes place in a raw mill to reduce the particle size of the components to a typical value of 10-15 % residue on a 90 um sieve. The output of the grinding process – called 'raw meal' – is transferred to a homogenization silo before the clinker manufacturing process.

Homogenization, process of reducing a substance, such as the fat globules in milk, to extremely small particles and distributing it uniformly throughout a fluid, such as milk.When milk is properly homogenized, the cream will not rise to the top. The process involves forcing the milk through small openings under high pressure, thus breaking up the fat globules.
