The resulting hard material is called "clinker", and then a certain amount of clinker is used to grind the clinker with gypsum into powder to make ordinary Portland cement (OPC) [1], [2]. Grinding consumes about 40% of the total electric energy, most of which is converted into heat, waste and serious environmental problems such as ...
Figure 1. Comparison between grinding of cement clinker with and without grinding aid (after Fuerstenau, 1990) Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill. As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding.
Abstract. Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on ...
This paper investigates the effect of various polyols, used as grinding additives, on selected properties of cement. The polyols investigated include ethylene glycol, …
Under-burning or over-burning typically results in too much fine clinker and can often be associated with lower quality. It is usual to target a mid-range for both free lime (1-2%) and granulometry (less than 25% passing 1mm and less than 25% above 25mm). For most mill systems, manufacturers recommend the following raw material size:
content of the ground sample is 2.1%. Grinding property of clinker: The clinker was crushed to the particle about φ3 mm in size. The clinker particle (weight: 50g) was ground at the ... 73.8% in the clinker and the mineral C 2S is 1.2%. The content of the mineral C 3A and C 4AF is approximately equal to the designed content
Grinding aids to increase grinding efficiency in cement production are materials that can produce large amounts of high-quality cement in a short time by reducing surface energy by preventing particle agglomeration and improving fluidity. In the paper, a grinding aid using glycerol-waste antifreeze(GAP) is prepared and its effect on the grinding properties of …
Here's an exploration of the role of clinker grinding in the cement manufacturing process: Particle Size Reduction: The primary purpose of clinker grinding is to reduce the particle size of the clinker. The raw clinker typically consists of clumps or nodules with varying sizes, which are not suitable for direct use in cement production.
combining clinker and gypsum - mon-plaisir-gourmand.fr. Raw materials (clinker, gypsum and anhydrite) sieved (1.18 mm) individually by crusher. After this, in the lab mill, the cement samples is the mixture of various ratio of clinker, and gypsum and anhydrite and have 3650±50 cm2/g fineness. During the grinding process, chemical grinding aid ...
The clinker production process requires high temperatures. Clinker is an essential component in the production of cement. The clinker is then mixed with gypsum to create cement. Transporting clinker can be a challenge due to its weight and fragility. Excessive amounts of clinker can lead to quality issues in cement production.
The results of this investigation points to surface tension modification of the clinker particles as one of the main effects of bio-glycerol addition during the grinding process. …

Clearly, such effects must be considered when designing grinding aid formulations [2-4]. This paper investigates the effect of various polyols, used as grinding additives, on selected properties of cement. The polyols investigated include ethylene glycol, propylene glycol and several derivatives or analogues of these glycols [1]. 2.
The relative hardness of the clinker, slag, and gypsum. Repeatability of testing. Several cement mixtures were ground 2 to 3 times in order to evaluate repeatability of testing determined following clinker grinding. Typical responses determined on cement ground with 0.11% amine-based GA at Ec of 35.7 kWh/ton are given in Table 2. The ...
By. admin. Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started …
Theisen, Kirsten, "Estimation of Cement Clinker Grindability", Proceedings of the International Conference on Cement Microscopy (1993), 15th, p. 1-14. In our laboratory the grindability of cement clinker is determined by grinding clinker plus gypsum while measuring the power consumption necessary for obtaining a certain fineness.
Figure 4-26 shows a typical comparison between the grinding of cement clinker with and without a grinding aid. Grachyan and Tavlinova (1973) report that 0.1% of dior tri-ethanolamine increases the rate of clinker grinding by 22-29X, with glycerol and lower alcohols being less effective.
presence of the polyol, we decided to investigate if indeed the positive effect of bio-glycerol addition during clinker grinding originates from its catalytic activity.
Some applications use crude glycerol, for example, Rossi and coworkers have proposed adding such glycerol to cement since it eases its grinding and handling while considerably enhancing the ...
The results indicated that the TIPA-0.11 (Triisopropylamine compound at a dosage level of 0.11%), with a Blaine value of 4069 cm2/g, and grinding efficiency of 19%, had the most significant effect ...
