This paper is concerned with a comparative analysis of modern cement grinding systems, namely, combined grinding (Comflex (R)), high-pressure roll mill (HPRM) grinding, and horizontal roller mill (Horomill (R)) grinding. Cement production trials were run with these grinding systems in the same cement plant by using the same clinker/gypsum feed to produce cements of almost identical chemical compositions and similar Blaine fineness values of about 3600 cm(2)/g. The grinding systems were compared in terms of specific energy consumption and mortar properties of the produced cements. The specific energy consumption and the cement setting times increased in the order of combined grinding, HPRM grinding, and horizontal roller mill grinding. No significant difference was detectable among the water demands of the cements from the three grinding systems. The HPRM cement was superior in strength development, particularly at early ages.

Active compliance control structure design for a robotic-grinding machine Dönder, Abdülhamit; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2017) Grinding operation has an advantage of precise form shaping in machining processes. However, if the surface profile is not known before the machining process, it is hard to obtain an accurate surface profile using a grinding operation. In this work, a novel method to compensate the form shaping errors in grinding operations due to the lack of a priori knowledge of the surface profile will be presented. Grinding operation on a workpiece with an unknown surface profile is aimed. Compliance force control is im...
A comparative analysis of the recent cement grinding systems with particle-based influences on cement properties Fidan, Berkan; Hoşten, Çetin; Kuleli, Ömer; Department of Cement Engineering (2011) The conventional cement grinding system, the ball mill, has very poor efficiencies in spite of innovative improvements. For this purpose, development of new techniques, which allow proper size reduction and uniform particle size distribution with less specific energy consumptions, have become a necessity. The aim of this study is to make a comparative analysis of the fairly new cement grinding technologies, COMFLEX® Grinding System, Roller Press and HOROMILL®, at the same cement production plant with the sa...
An Experimental Study of Cutting Performances of Worn Picks Dogruoz, Cihan; Bolukbasi, Naci; Rostami, Jamal; Acar, Cemil (2016-01-01) The best means to assess rock cuttability and efficiency of cutting process for using mechanical excavation is specific energy (SE), measured in full-scale rock cutting test. This is especially true for the application of roadheaders, often fitted with drag-type cutting tools. Radial picks or drag bits are changed during the operation as they reach a certain amount of wear and become blunt. In this study, full-scale cutting tests in different sedimentary rock types with bits having various degree of wear we...
Influence of high-pressure grinding rolls on physical properties and impact breakage behavior of coarsely sized cement clinker Camalan, Mahmut; Onal, Mehmet Ali Recai (2016-01-01) High-pressure grinding rolls (HPGR) are widely used in cement clinker grinding prior to ball milling. The efficiency of HPGR was previously related to two capabilities: (a) efficient stressing mechanism and (b) weakening of particles which lead to finer product sizes after subsequent ball milling. This study aimed to investigate the influence of HPGR on the impact breakage behavior of coarsely sized cement clinker. Drop weight tests were conducted on three single-size samples from both feed and product stre...
Comparative assessment of the efficiency of seismic isolation for seismic retrofitting of highway bridges in regions of low-to-moderate seismicity Karalar, Memduh; Dicleli, Murat (null; 2019-07-06) In this paper, the economical and structural efficiency of friction pendulum bearings (FPB) for retrofitting typical seismically vulnerable bridges in the State of Illinois is studied. For this purpose, a bridge was selected by the Illinois Department of Transportation (IDOT) to represent typical seismically vulnerable bridges commonly used in the State of Illinois. A comprehensive structural model of the bridge was first constructed for seismic analysis. An iterative multi-mode response spectrum (MMRS) ana...
