KR100244003B1 Cement clinker grinding method using vertical

The present application provides a cement clinker grinder with an orthogonal roller mill and a cement clinker grinding method. In this method the feed material is ground by a table and a roller. Subsequently, all of the resulting grounds are obtained from the table bottom and passed to the separator by a bucket elevator for sorting the grounds.The selected type of rheometer eliminates the influence of grain segregation on the measurements, occurring at high water to cement ratios. The procedure is mainly used for well cementing materials (acc. to PN-EN ISO 10426-1:2009 ). The compatibility of the system: cement—grinding aids—acrylate-based superplasticizer The Effect of Various Grinding Aids on the Properties of Cement

Analysis of high clinker ratio of Portland Composite Cement (PCC)

According to Indonesian Standard SNI 15-7064-2004, Portland Composite Cement (PCC) or blended cement is defined as a hydraulic binder which consists of clinker, gypsum and one or more inorganic materials where their contents range from 6% to 35% of the total mass of PCC. However, some factories still have their clinker levels in cement ratio values, coarser cements can be 20% by pre-crushing the clinker using the Barmac crusher.

Investigation of glycerol polymerization in the clinker grinding

In order to investigate the influence of bio-glycerol mixing with the clinker, samples were prepared and analyzed by FT-IR spectroscopy.The simple physical mixing of the clinkers with bio-glycerol does not induce any important chemical transformations in the structure of the cement precursor, as indicated for clinker B ().Similar results were observed for the US6193176B1 US09/020,417 US2041798A US6193176B1 US 6193176 B1 US6193176 B1 US 6193176B1 US 2041798 A US2041798 A US 2041798A US 6193176 B1 US6193176 B1 US 6193176B1 Authority US UUS6193176B1 Cement clinker grinding method using vertical
