Vertical Roller Mill Cement Raw Material Grinding. Raw Material Drying-Grinding - Cement Plant Optimization. Vertical roller mills can typically handle an aggregate moisture of up to 20 in raw materials and consumes about 30 less power in grinding. Hence it is commonly preferred for grinding operation in new plants of higher capacities.
Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.

ES Processing Cement Mill Optimizer Benefits: 5-20% increased production with existing equipment. Unprecedented improvement in quality of product = higher cement strength. Enhanced cement quality while significantly reducing the Blaine and residue standard deviation. Lower energy consumption = lower electricity costs.
This separator is from KHD Humboldt Wedag AG. - The V-separator is generally used with a pregrinding system (Roller Press). - Applications mainly for raw meals, clinker and slag. - The main objective of this separator is to remove a maximum of fines particles from the Roller Press feed in order to decrease the problems of vibrations.
The separator's efficiency is determined by drawing a Tromp curve based on particle size distribution analysis. The separator's performance can be improved by changing the adjustments or replacing worn components. The operational controls are …
