Cement Roller Press. The cement roller press is a new kind of cement mill. It is usually used as a pre-grinding system to replace some functions of the ball mill so that the output of the ball mill can be increased by 30-50%. At the same time, it can also be singularly used in cement plant as a clinker grinding machine.
The most noticeable feature of the roller press cement pre-grinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required. The finished product cement from this system has all been ...

Designed for granulated blastfurnace slag (GBS), this roller press remains in operation. However, roller press design has been adapted to grind raw materials, cement and slag as part of a continuous process to improve and extend its use. Today it remains the most cost-efficient comminution method.
In 1996, the first HEXADUR® roller was installed at a Norwegian cement plant onto a Köppern HPGR for testing under real service conditions compared to a conventional welded (hard faced) roller [6]. The thickness of the HEXADUR® layer was 10 mm. The wear protection of the counter roller consisted of a
Abstract-Shree Cement / Suratgarh are operating a semi-finish grinding system type "S" which consists of a roller press below the V-Separator. The Static- Separator is directly connected to the air inlet spiral of the SKS- Separator. The ball mill discharge is feed to the top of the SKS-Separator.
The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.. The …
Vertical roller mills and ball mills represent two clearly distinct technologies. However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved …
The roller press is used for crushing minerals like clinker, limestone, slag, and trass in the cement industry. It crushes minerals between two counter-rotating cylinders under high pressure, forming a thin band or "cake" of crushed material. This crushing reduces energy consumption in grinding mills and extends the life of mill components. The roller press …
