3/1/2012· More than 65 of the mills are producing high-grade cements in energy-efficient combi-grinding systems all around the world. The main characteristic of such a combi-grinding system is the pre-grinding of cement clinker in the POLYCOM®, which works in closed circuit with the static-dynamic separator SEPOL® PC, and afterwards finish grinding in a subsequent ball mill.
12/19/2016· nace slag or cement grinding, the SEPOL ® QM or RM high-efficiency separator is integrated into the mill housing of our roller mills. SEPOL® QM and RM: the compact one for roller mills Layout of a QUADROPOL ® plant configuration Construction of the SEPOL® LM Layout of an air-swept mill/SEPOL ® LM plant configuration SEPOL® LM: the specialist
10/23/2015· They are used in grinding of cement raw materials (raw meal) (i.e. limestone, clay, iron ore), cement clinker and cement additive materials (i.e. limestone, slag, pozzolan) and coal. Multi-compartment ball mills are relatively inefficient at size reduction and have high specific energy consumption (kWh/t).
9/1/2014· High efficiency separators are demanded mostly by cement industry and some of the studies reported that it was achievable to decrease the bypass percentage of the classification process down to 5–10% and increase the overall production rate of the grinding circuit by 15–35% at the same cement quality . High efficiency separators are also found applications in integrated grinding systems such as vertical roller mill,air classifier mill and air jet mills
potential. Compared to a roller mill, it is thus able to save up to 20 percent of the energy required for grinding; compared to a conven-tional ball mill, it can even save up to 50 percent. Maximum energy savings are achieved by combining the polycom ® with a static-dynamic sepol ®
4/1/2010· Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %.
Cement grinding will take place in two ball mills with SEPOL high-efficiency separators. The plant will also have a 6000t cement silo as well as cement packing and loading facilities. Published under Cement

Efficient prevention is the key in oral care, to keep the mouth of the patient healthy and free of caries. Next to the elimination of risk factors, adjuvant products help in preventing, stabilising and remineralising the initial carious lesions (white spot lesions).
SEPOL®-RM high-efficiency separator In Polysius roller mills, including the QUA-DROPOL ®, the SEPOL -RM high-efficiency separator is a standard component for all grinding applications, whether coal, lime-stone, granulated blast furnace slag or cement. The SEPOL®-RM is integrated into the mill housing. SEPOL®-LM Housing area, rotor [m2] Separating air
SEPOL® high-efficiency separators are installed in grinding plants equipped with tube mills, roller mills and high-pressure grinding rolls. The fact that over 500 SEPOL® separators are installed all around the world confirms the universal acceptance of this separator concept.
SEPOL® high-efficiency separator For separating the ground material into finished product and oversize, Polysius roller mills include a SEPOL® dynamic high-efficiency separator, which can be adjusted in accordance with various parameters. Due to its excellent selectivi-ty, this separator drastically reduces the specific power requirement for the grind-
11/1/2001· E = C exp(a) ~ exp(a.X ) +exp(a) 2 ] The separator performance can be modelled in terms of ds0,, C, a. and ss. Zhang et al. (1988) sucessfully applied this approach to older types of air separators. A third generation dynamic separator, the Polysius Sepol, is widely used in cement grinding circuits in Turkey.

Ball mills for fine grinding cement clinker and additives are widely used around the world. To improve the efficiency of a ball grinding the ball mills are transferred in closed circuit with air
One of the principal reasons for the outstanding success of the POLYCOM® High Pressure Grinding Roll (HPGR) in the cement industry is its low power requirement. Today, this mill is employed all around the world for the grinding of cement raw material, cement clinker and

12/1/2009· Another characteristic feature which can be observed in the second compartments of cement mills is the progressive fineness decrease towards the last meter of the compartment due to the coarse particle accumulation and probable blockage at the discharge diaphragm as the size distribution at the 5.2 m was found to be coarser than the one at the 4.1 m.
10/21/2014· Cement grinding will take place in two ball mills with SEPOL high-efficiency separators. The plant will be rounded off with a 6000t cement silo as well as cement packing and loading facilities.
