System is specifically designed for construction chemicals and powder gypsum plants. It is a common fact that the excess of fine particle content inside the calcite fillers affects the standard mechanical properties and cause cracking of the final product. Main target for the system is to reduce the fine particle output during the milling process. A secondary aim is to manage the particle morphology. Hence the overall quality of the final product increases by having round particles after milling process which makes the application (ex. plasters) easier. On the other hand the manufacturing cost decreases due to reduced chemical additives usage.

- Screened calcite is fed in to the system by the help of a regular or an electronic scale feeder.

- The material is ground under control by the hammer mill (CDK series). The fine particle content at the mill exit can be adjusted.

- After the mill, air classifying unit (SP series) takes place for further classifying. The coarse exit of the classifier is returned to the mill via primary vibration screen. 

- Final particle classification is done by a vibration or a tumbler screen.

- Classified particle groups are then weighed by an electronic weigh batch hopper and mixed in the powder mixer. All the process, particle ranges and proportions can be managed.

- Final product can be directed into sack, big-bag or silo truck filling station.

- Automation management is done via central processing computer with SCADA. Process flow can be managed by using a mimic diagram. Simultaneous changes can be made, reports can be obtained, manual controls can be applied. Remote connections are available via ethernet module.
