As the main pollutant of paper mills, black liquor has brought great pressure to the wastewater treatment process of paper mills. Based on the coal-water slurry gasification (GS-CWS) technology, this paper designed the gasification system of black liquid coal-water slurry (GS-BLCWS) by utilizing weak black liquor of pulp mills, …
Section snippets Materials. The coal used in the experiment was gathered from Nandira mines in Odisha, India, to carry out the study. Initially, 8 kg of coal samples were collected and grounded in the ball mill followed by a Jaw crusher roll crusher to get various sizes of particles like −38 µm, −75 µm, (90–300) µm (210–300) µm. −38 µm, …
Explosion-proof and readily flowable, the slurry is easy to store. Once vaporized, it can be used as a cheap, clean, and energy-efficient alternative to petroleum,Coal-water slurry …
The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
Explosion-proof and readily flowable, the slurry is easy to store. Once vaporized, it can be used as a cheap, clean, and energy-efficient alternative to petroleum,Coal-water slurry ball mill is different from coal ball mill. Below are some basic data related to the coal-water slurry produced by our ball mill. Average Concentration: 66.31%
Coal-water slurry (CWS), a mixture of pulverized coal, water, and additives, is a clean liquid coal-based fuel for gasification. Superhydrophobic surface modification using a secondary particle-second liquid system is an effective CWS preparation method. In this study, the effect of the sphericity of the secondary particles …

A technology of ball mill and coal-water slurry, which is applied in grain processing, etc., can solve the problems of long transmission chain, large equipment footprint, and high investment cost, and achieve the effects of reducing the amount of addition, improving quality, and being convenient to use
Coal-water slurry fuel was made in a ball mill which pulverised the coal or coal sludge. This was done near a coal mine in Belovo, Siberia. The coal-water slurry fuel was transported through a pipeline to Novosibirskaya TEC-5, Novosibirsk, a distance of 262 km (163 mi). The pipeline had three intermediate pumping stations.
The coal powder was slowly mixed in a pot containing a certain known quantity of dispersant and deionized water. The contents were continuously stirred by a mixer during the addition of coal, and then the stirring of the slurry was continued for another 10 min at 1200 rpm to ensure the homogenization of CWS.The slurry so …
Dispersants, serving as an essential raw material in the formulation of coal water slurry, offer an economical and convenient solution for enhancing slurry concentration, thus stimulating significant interest in the development of novel and efficient dispersants. This paper intends to illuminate the evolution of dispersants by examining …

Coal water slurry (CWS) is a coal–water fuel of coal particles suspended in water. It maintains not only the original physical characteristics of coal but also mobility and stability same as petroleum. Coal water slurry is a kind of fuel with low cost and efficient burning. It is also a fuel protecting environment and replacing oil.

This paper presents the results of an investigation of energy requirements for grinding of coal-water slurries in conventional and high speed stirred ball mills. The high speed stirred ball mill, featuring a rotor-stator type of stirring device, has been found to outperform a tumbling ball mill for wet grinding of minus 12 mesh coal to a fineness meeting the …
The results of studies of calorific value and dynamic viscosity of coal-water slurries with addition of a pyrogenetic liquid are presented. It was found that addition of small quantities (not more than 10 wt.%) of a pyrogenetic liquid raises the calorific value of the slurries by 6%.
The Yulin coal that dried under vacuum was first crushed below 10 mm and grinded in a ball mill to obtain pulverized coal. The particle size distribution of the pulverized coal is measured using a laser particle size analyzer (Mastersizer 2000), and the result is given in Fig. 1 .
