Vertical Mills. For more than 50 years vertical mills have been the mill of choice for grinding raw materials into raw meal. More recently they have become widely used for cement production. They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body.
Vertical cement mill pressurize with a hydraulic system, the pressure acts on the material between the grinding roller and the grinding disc, so as to achieve the purpose of grinding. Vertical cement mill is applied for the processing of nonflammable and nonexplosive mineral materials with mohs hardness below grade 8 and humidity less than 10%.
Vertical Roller Mills (VRMs) have been the standard option for raw materials grinding in the cement industry for several decades. FL has supplied the global cement industry with leading VRM designs for all applications since they were first brought to market. The OKTM mill has been FL's standard cement VRM since 1993.
For the past three decades the vertical roller mill has emerged to be the preferred choice for grinding raw materials[12]. It has advantages like low power consumption, process simplifications and

A VSI mill (vertical shaft impactor mill) is a mill that comminutes particles of material into smaller (finer) particles by throwing them against a hard surface inside the mill (called the wear plate). Any hard or friable materials can be ground with low value of metal waste. This type of mill is combined with a classifier for fine tuning of a product size.
As the pregrinder, vertical roller mill is often used considering its great grinding efficiency. Fig. Raw material grinding system Results Table Effect of implementing raw material pregrinder By this production increasing, it is expected that operation in the daytime can be shortened and then power cost can be reduced. Cost estimation
The vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the benefits of simple structure and low cost of manufacture and use. Vertical roller mills have many different forms, but they work basically the same. All of these forms come with a roller (or the equivalent of roller ...
Vertical roller mill (VRM) is a largescale grinding equipment, which is used to grind raw materials from block/granule into powder. Due to harsh production environment and inconsistent raw ...
The cement roller press and cement mill are used to grind the cement raw material to the required particle size and packaging. There are two types of cement mill including a ball mill and vertical cement mill. The packing machine is used to pack the finished cement product into a bag according to a certain weight.
The vertical mill of raw material is used for grinding cement raw material or cement clinker and other industrial materials such as construction, chemical and ceramic. It has a series of advantages, such as small volume, light weight, less land occupation, low electricity consumption, long life and so on.
The energy consumption of cement vertical mill grinding system is relatively low, which is 10%30% lower than that of the cement ball mill grinding system. And the decreased value will increase with the rise of raw material moisture. Large Drying Capacity. The cement vertical grinding system can make full use of the lowtemperature exhaust gas ...
