Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same.
Sep 23, 2021 Pakistan Askari Cement has awarded a contract to Germany-based Gebr. Pfeiffer for the supply of three of its MVR vertical roller mills to replace the existing mills at its Nizampur cement plant. Two of the mills will be MVR 5000 C-4 cement mills with the capacity to grind 360t hr of clinker to a fineness of 3250 blaine.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Aug 30, 2012 There is a horizontal filled with steel balls. Clinker reach in this rotating drum after cooling. Here, steel balls tumble and crush the clinker into a very fine powder. This fine powder is considered as cement. During grinding gypsum is also added to the mix in small percentage that controls the setting of cement.

Subsequently, in early 2000 few big players begun to use Polycom technology in Cement grinding line. The technology is a high-pressure grinding mill to produce cement. Shortly after the introduction of the Polycom system, another system called VRM (Vertical Roller Mill) technology had grabbed the attention of big giants in the field.
Grinding Aids are used in the cement mill (Ball Mill, Vertical Roller Mill, HoroMill) to increase the productivity, save electrical energy and or to increase the fineness and improve defined cement properties, e.g. powder flowability. A typical example is SikaGrind -400.
