Abstract. The main objective of the paper herein presented is to analyze an equipment failure in a cement production line, namely the existence of cracking of the concrete inside the cyclone towers (with the fall of this coating). The observed failures are recurrent and responsible for reducing the period between stops of the production line.

Abstract-Shree Cement / Suratgarh are operating a semi-finish grinding system type "S" which consists of a roller press below the V-Separator. The Static- Separator is directly connected to the air inlet spiral of the SKS- Separator. The ball mill discharge is feed to the top of the SKS-Separator.
Hydraulic Roller Press
A dynamic separator, which maintains the desired quality of the final product is paired with a static separator that ensures effective deagglomeration and aids in drying the feed material. Upgrading a conventional ball mill with the Hydraulic Roller Press for semi-finish setups can increase production by up to 100 per cent or more, while also ...
Christian Pfeiffer FIX and QDK-F · Christian Pfeiffer
The dymanic separator QDK-F is combined with the static separator FIX to match the requirements of combi-grinding, systems which consist of roller press and ball mill. The material enters the QDK-F through two feeding points: an airflow and two feeding chutes above the separator. The QDK-F provides a top cut of up to 20 µm.

Numerical investigation of the vortex breaker for a dynamic …
A high-efficiency dynamic separator is used to control the final product fineness of the grinding circuit. This equipment was developed mainly for the high demands of the minerals, food, pharmaceutical, and cement industries. In this study, we focused on the dynamic separator used in cement industry plants.
Christian Pfeiffer QDK-M Separator · Christian Pfeiffer
The separator classifies the material stream into two partial streams depending on the particle size. The separator is charged with powdered material, consisting of particles of different sizes, in a continuous process. It defines the finer particles as the finish product by selecting them from the feed material.
Holderbank Cement engineering book
HOLDERBANK: 2.3.4 Operation. The separator is operated with constant airflow, fineness is controlled by the speed of the separator cage. Only in extraordinary cases where motor power or gearbox reduction ratio. pose limits to separator speed, the airflow may be decreased to obtain the desired fineness.
