A large cement factory as an example, according to the requirements of process and control parameters of production line of raw mill, this paper researches and designs the automatic control system of cement raw mill production line based on PCS7 and PROFIBUS. The design of the whole system consists of three levels: field layer, control layer and operation layer which are connected by Ethernet
Sep 23, 2018· This is the practical demonstration of how a raw mill operator puts the raw mill of a cement mill in operation by using Siemens PCS7 DCS OS panel. This raw m...
This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, 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. This is achieved in a cement raw mill.

know-how in the field of cement production, established together with many cement manufacturers worldwide. The engineers who develop and support CEMAT can fall back on more than 35 years of experience in the cement industry. CEMAT is now based on the mainstream process control system of Siemens, SIMATIC ® PCS 7, and
a PC, including the resulting development of raw material homogeneity. This ensures individual project. Whether a given deposit is a suitable supplier of raw materials for the cement production process is decided on the basis of precise examination and analysis data. As a first provide the raw mill with the feed size range it requires.

Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

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.
Raw mill has features such as high capacity, high efficiency, energy saving and environmental protection. Raw mill usually is used for grinding various ores and other materials in cement, electric power, metallurgy, chemical industry and other industry. Our products special features: 1. Product fineness is adjustable and uniform. 2.
