Raw mill is generally called cement raw mill, raw mill in cement plant, it refers to a common type of cement equipment in the cement the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.
Raw Mill In Cement Plant,Cement Making Plant. This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (28%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder.
Overall vertical roller mill sales in 2016 were above the longterm market trend, highlighting the importance of FLs position as a lead supplier for VRMs in the cement industry. The strong market for VRMs is mostly driven by ongoing emphasis on energy efficiency in the global cement industry and continuing growth in developing markets.
Cement plants normally have sufficient silo space for 120 weeks production, depending upon local demand cycles. The cement is delivered to endusers either in bags or as bulk powder blown from a pressure vehicle into the customer''s silo. In industrial countries, 80% or more of cement is delivered in bulk. Our raw mill has been widely used in

We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.
The contract includes two raw cement mills and three clinker mills for the plant at Biskra. With these mills raw cement meal can be ground to a fineness of 12% sieving residue with 90m at a processing capacity of 500t/hr and the cement clinker to a fineness of 3,400 Blaine.
VRMs are installed in new cement plants with dry systems, and also often replace ball mills during plant modernization, where the raw material moisture content is less than 25%. As of 2010, VRMs for raw material preparation had a penetration rate of 45% in Chinese market.
