Manufacturing cement requires energy intensive processes; and consumes almost 15% of the total demand for energy in industry [3].On average, to produce one ton of cement, 3.4 GJ of thermal energy (in dry process) and 110 kWh of electrical energy are needed [4, 5].Furthermore, manufacturing a ton of cement releases 0.73–0.99 tons of CO2 [6] which …

Abstract The results of industrial comparative tests of batches of grinding balls with a diameter of 40, 60, and 80 mm from chromium–molybdenum steel of the nominal grade ShKhM and balls of the current manufacture from rail steel in the first chambers of drum mills while grinding of cement are presented. As the test results showed, total specific consumption of …

In order to achieve high efficiency absorption of CO 2 by fresh cement paste, a special CO 2 absorption device was designed. Then the influences of stirring rate (SR), water-to-cement ratio(W/C), superplasticizer type and its addition order on the CO 2 absorption rate (CO 2 AR) and CO 2 ultimate absorption amount(CO 2 UAA)were investigated. Moreover, the fluidity …

Increasing the effective volume of the ball mill can increase the efficiency of the mill production. Ordinary alloy linings are thick and heavy, which reduces the effective volume of the mill and …

There is little discussion found in literature about the efficient use of cement. In a pioneer paper, Popovics [12] presents the f eco, the compressive strength which gives the highest efficiency of strength development (f r), which is defined as the strength developed by one unit of mass of cement. On the other hand, the economic efficiency of a concrete mix design was …

Optimization of the Cement Ball Mill Operation. Optimization addresses the grinding process, maintenance and product quality. The objective is to achieve a more efficient operation and increase the production rate as well as improve …

As grinding accounts for a sizeable share in a cement plant's power consumption, optimisation of grinding equipment such as ball mills can provide significant cost and CO 2 emission benefits …

A study is conducted to evaluate the efficiency of cement companies in India in order to identify the sources of inefficiencies and formulate proposals for improving the productivity of those ...

In the cement industry, the clinker grinding step consumes about one-third of the power required to produce one ton of cement. This refers to an average specific power consumption of 57 kWh per ton [1].Such large amounts of energy justify the need to improve the energy efficiency of comminution process.

Description. A cement mill is an important component of the cement manufacturing process in a cement plant. The cement ball mill is designed to grind materials in either a dry or wet mode, and it finds widespread usage …

Japan is at the forefront of energy efficiency in the cement industry. In terms of energy efficiency, Europe averages 4.1 GJ/t of cement, which does not match Japan's more efficient 3.1 GJ/t. In comparison, the average energy consumption in the US (5.3 GJ/t) and China significantly exceeds that of Europe.

(DOI: 10.1016/J.CEMCONCOMP.2010.07.009) At present, the cement industry generates approximately 5% of the world's anthropogenic CO2 emissions. This share is expected to increase since demand for cement based products is forecast to multiply by a factor of 2.5 within the next 40 years and the traditional strategies to mitigate emissions, focused on the …

The electrostatic precipitator (ESP) is a type of modern industrial dust collecting equipment with a dust removal rate of over 99%.. Its high dust cleaning rate makes it very popular in many industries with large flue gas emissions, such as power generation, cement making, metallurgy, and chemical industry. As a kind of mechanical equipment, after working for a long time, the …

In the literature, there are many studies that measure the efficiency of the Turkish cement industry by using the DEA. However, a significant portion of these studies are focused on evaluating the financial performance (Karsak and Iscan 2000; Kayalidere and Kargin 2004; Kula and Ozdemir 2007; Elitas and Eleren 2007; Bayyurt and Sagbansua 2007; Kula et al. 2009; …

400 g cement with dopamine at a dosage of 0–0.20% by weight of cement was put into an agitator kettle and stirred 10 s at a low speed. Then, 140 g of water was added to the solids. The cement paste was stirred for 5 s at a low speed and for 15 s at a high speed.

To make the milling more efficient, we must first be acquainted with the factors. They are mainly the ball mill structure, the rotation speed, the ball mill media, the lining plate, the material fed and the feeding speed, etc.

Aqueous carbonation is a different carbonation approach that employs a bulk liquid environment to create a fully saturated pore system [20].In spite of the lack of a gas path, carbonation can proceed by aqueous diffusion of the carbonate species (CO 3 2− /HCO 3 − /H 2 CO 3) generated after CO 2 dissolution [21, 22].As such, the control of the carbonation …

The self-healing efficiency for reference concrete and concrete with empty EAs was less than 5%. The self-healing efficiency for 50 μm cracks was similar to that of the reference concrete, indicating that no healing occurred for 50 μm cracks. For PU EA concrete, the closure of cracks was above 80% for 100 μm, 250 μm, and 450 μm cracks.
