• Vertical roller mill (VRM) • Ring roller mill or Horo mill Even though there are various types of systems available for cement grinding, ball mills are predominantly used machines for cement grinding in large number of cement plants. In this paper authors are covering the process diagnostic study of Ball mill for cement grinding. 2.
Vertical Roller Mill is a new type advanced pulverizing equipment featuring good performance and drying function. Integrated with drying, pulverizing and powderselection, Vertical Roller Mill is widely applied in cement, chemical, coal and electric power industries. It has become the mainstream equipment in the pulverizing industry.
In 1954 a Jet Pulverizer was developed in which operates like a Vertical Pulverizer only the item is pulverized by the high speed air action. For example, forcing coal against coal. Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed
• Rapid process dynamics are a challenge to operating a vertical roller mill (VRM) • Surpasses the classic methods if the controlled process demonstrates significant disturbances • A high degree of attention to the process states is required in order to make punctual corrections • Process states are displayed and controlled continu
Improvement of cement performances through the use of grinding aids in vertical roller mill ''Arcangelo, – Mapei SpA, Milan, Italy Abstract Due to the stringent requirement of energy saving, the use of vertical roller mills for cement grinding is now common. Even though the reliability and operation stability of modern VRM is very
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Vertical roller mill wear parts. The vertical roller mill by the separator, roll grinding, grinding, pressure device, reducer, motor, shell etc.. The separator is an important component for ensuring product fineness, it consists of the drive system, rotor, guide vanes, a shell, a coarse powder blanking cone outlet, etc..
The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
