Abstract. The effects of ball milling processes on specific surface area, particle size distribution, and compressive strength at different curing ages of one-part alkali-activated nickel slag mortar (AATY) were investigated. Results show that the influence The optimum process parameters setting concluded that balls to powder weight ratio are 20:1, the optimum ball mill working capacity is 2 L while the optimum Comparative Study on Improving the Ball Mill Process

Effect of Grinding Media Size on Ferronickel Slag Ball

In order to simulate the industrial ball milling operation, the feed to the mill consisted of slag with natural size distribution less than 850 μm. Grinding kinetic modeling and the attainable region (AR) In general, the most significant effect of mechanical activation is to change the PSD of materials; thus, these distributions for ground steel slag are Mechanical activation of steel slag to prepare supplementary

Preparation of one-part alkali-activated nickel slag binder using an

When the ball milling time is too short, the fineness of nickel slag is too small and the activity is low. An optimal ball milling process was proposed by comparing the energy efficiency of ball milling with the compressive strength of AATY. For this optimal process, the ball loading rate is 30%, ball.• There is no fundamental restriction to the type of ball mill used for organic synthesis (planetary ball mill, mixer ball mill, vibration ball mill, ). • The scale of reaction determines the size and the type of ball mill. • Vessels for laboratory vibration ball mills are normally restricted to a volume of 50 cm3.

Ball milling: a green technology for the preparation and

Ball milling is a simple, fast, cost-effective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and the chemical modification of cellulose nanocrystals and nanofibers.

Undisturbed nickel slag with an average particle size of 3–4 mm was used. Chemical composition analysis results for the nickel slag were acquired by the X-ray fluorescence technique and shown in Table 1.A sample of undisturbed nickel slag is shown in Fig. 1 (a). During the ball milling process, a ball milling machine was used to mix The ultrafine slag slurry (UFSS) was obtained by the process of grinding the original slag in a wet ball mill, which was mixed in concrete directly. The durations of grinding were 20 min, 40 min, and 60 min which were used to replace Portland cement with different percentages, namely, 20, 35, and 50, and were Influences of Ultrafine Slag Slurry Prepared by Wet Ball Milling

Effect of Grinding Media Size on Ferronickel Slag Ball Milling

The aim of this study is to evaluate the effect that the size of grinding media exerts on ferronickel slag milling efficiency and energy savings. A series of tests were performed in a laboratory ball mill using (i) three loads of single size media, i.e., 40, 25.4, and 12.7 mm and (ii) a mixed load of balls with varying sizes. In order to simulate Coal-gasification slag (CGS) was subjected to mechanical grinding by three different methods. We studied the effects of mechanical activation on various physical and chemical characteristics of the CGS, including particle-size distribution, specific surface area, mineral composition, degree of crystallinity, particle morphology, chemical Effects of Mechanical Activation on Physical and Chemical

Effect of ball size and powder loading on the milling efficiency of

Keywords: Ball size; Particle size; Powder loading; Rotation speed; Wet ball mill 1. Introduction Wet ball mill is one of the most predominantly used method for the purpose of mixing and grinding of raw materials in laboratories and industry [1–3]. The ball mill process is very complicated process governed by many parameters, such asIn the process of ball milling, it is difficult to realize the complete dissociation of the middlings involved in this study by using steel balls in this scale range. This is because the size of the grinding medium is too large compared with the particle size of the grinding object to provide enough grinding surface to realize the dissociation of fine Recovery of Carbon and Cryolite from Spent Carbon Anode Slag

Ladle Steel Slag in Activated Systems for Construction Use

Steel slag is a residue from steel production, which can be either black slag (melting stage) or white slag (refining stage), depending on the stage at which it is obtained. In the European Union in 2016, 18.4 Mt of steel slag (black and white) were produced [ 3,4 ], of which it is estimated that more than 700,000 tons were white slag The utilization of nickel slag has attracted much attention due to its high-content of valuable elements. As a part of these efforts, this work focuses on whether magnetite crystals, obtained from nickel slag via molten oxidation, magnetic separation, and ball-milling can be used as a microwave absorber.
