Opis:
Several optimization studies were made to increase metal recovery and reduce operational costs of the concentrator in Siirt Madenköy copper mine. In consequence of these studies, effects of the changes in operating parameters, cost and plant recovery will be examined at this article. In this article, we will discuss two important revision studies, which are (i) replacement of 500 mm hydrocyclone set used in ball mills with 350 mm of hydrocyclone set, (ii) replacing the present Ball Mill with a SAG mill. Correspondingly elimination of the crushing and screening plant, (iii) increasing the scavenger cells from 4 to 6 by the addition of 2 more cells. In consequence with this feeding the middling tail to the increased scavenger cells which was treated as a part of final tail before this change. We will examine the effect of all these changes to the final recovery, concentrate grade and final cost.

Opis:
The recovery of spent carbon anode (SCA) materials plays important roles in environment protection and resources recycling, while this cannot be efficiently achieved without liberation. In this study, grinding characteristics of spent carbon anode from aluminum electrolysis in both ball mill and rod mill were analyzed, and compared based on the utilization of the selective Fuerstenau upgrading curves. In addition, the different grinding mechanisms of ball and rod milling were evaluated by analyzing the shape factor and surface roughness of the ground samples. Results of mineralogical characterizations indicated that carbon particles (d50 = 46.86 μm) presented in the SCA were closely associated with cryolite particles. At 5 min grinding time, the maximum selective comminution factor (β) values of ball milling and rod milling were 2.00 and 1.63, respectively, indicating a higher degree of selective comminution of SCA was achieved from ball milling. Comparisons of the valuable component content (cv, cum) of -125 μm ground particles and the shape characterizations of 74–125 μm ground particles generated from ball and rod milling manifest that a direct relationship exists between the degree of selective comminution and the grinding mechanism.

The efficiency of talc mechanical activation by means of two different mechano-activators - centrifugal and attrition mill is investigated in this study and the comparative analysis of the characteristics of obtained talc powders is presented. A new approach for obtaining high-grade talc concentrate with low Fe2O3 content is achieved through effect of mechanical activation of talc accompanied by hydrometallurgical process. The applied mechanical activation process conditions of ultra-centrifugal mill were defined by number of rotor revolutions, sieve mesh size, and current intensity. These operating parameters of the ultra-centrifugal mill were variable. Ultra fine grinding of talc in attrition mill (attritor) was carried out in various time intervals - from 5 to 15 min. The following technological parameters of the mechanical activation were monitored: time of mechanical activation, circumferential rotor speed, capacity of ultra-centrifugal mill, and specific energy consumption. The investigation was based on a kinetic model. The structure and behavior of activated samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, and differential thermal analysis (DTA).

Opis:
Vibratory mills are applied in processes of mechanical production of powders, micropowders, nanopowders and nanostructures. The paper comprises a description of tube mills operation: vibratory and rotary-vibration ones. It also presents their application and construction description including two industrial mills elaborated at the AGH University of Science and Technology in Krakow. There is also a brief analysis of existing models of mechanical vibratory mills. The main part of the paper deals with a model of mechanical vibratory mill known as a layered model. The most important element is a quantitative view of the load movement (grinding media with material) in the chamber. The model also takes into account the whole mechanical system of the mill i.e. inertial vibrator, vibro-isolation system and drive. The model was elaborated for the purposes of the mill computer simulation. During the simulation there were accepted the same technological (grinding media, ground material, grinding process) and kinematic parameters of the mill as the ones that occur in a real object i.e. the laboratory rotary-vibration LAMOW-B-5/2 mill. The paper includes results of a computer simulation of the model. The final part of the work verifies the computer simulation on the same mill and at the same kinematic and technological parameters of the mill and grinding process. Positive results of the verification indicate some possibilities of its application in designing of industrial and laboratory vibratory and rotary-vibration mills.
Młyny wibracyjne stosuje się w procesach mechanicznego wytwarzania proszków, mikroproszków oraz nanoproszków i nanostruktur. W pracy zamieszczono opis działania rurowych młynów: wibracyjnych oraz obrotowo-wibracyjnych. Podano także ich zastosowanie oraz opis budowy, w tym dwóch młynów przemysłowych opracowanych w Akademii Górniczo-Hutniczej. Podano krótką analizę znanych modeli mechanicznych młynów wibracyjnych. Zasadniczą część pracy stanowi model mechaniczny młyna wibracyjnego, zwany modelem warstwowym, którego najważniejszą częścią jest ilościowe ujęcie ruchu ładunku (mielników z materiałem) w komorze. Model ten uwzględnia także cały ustrój mechaniczny młyna, to jest wibrator bezwładnościowy, układ wibroizolacji oraz napęd. Model opracowano dla potrzeb symulacji komputerowej młyna. W symulacji przyjęto identyczne parametry technologiczne (mielników, mielonego materiału, procesu mielenia) i kinematyczne młyna które występują w rzeczywistym obiekcie, czyli laboratoryjnym młynie obrotowo-wibracyjnym LAMOW-B-5/2. Praca zawiera wyniki symulacji komputerowej tego modelu. Finalną część pracy jest weryfikacja symulacji komputerowej na tym samym młynie i przy tych samych parametrach kinematycznych i technologicznych młyna oraz procesu mielenia. Pozytywne wyniki weryfikacji modelu warstwowego wskazują na możliwość jego zastosowania w projektowaniu przemysłowych i laboratoryjnych młynów wibracyjnych i obrotowo-wibracyjnych.

Opis:
In this research, the effect of ball size distribution on the mill power draw, charge motion regime and breakage mechanism in a laboratory ball mill was studied using the discrete element method (DEM) simulation. The mill shell and crushing balls were made of Plexiglas® and compressed glass, respectively. Modeling was performed using Particle Flow Code 3D (PFC3D). Model parameters were back-calculated by comparing the power draws and images obtained from simulation and laboratory test works. After determining the model parameters, the mill was simulated in mill fillings of 15, 20, 25, 30, 35 and 40% with ball media of 2 and 2.5 cm in diameter. For every mill filling, the numbers of big and small balls were changed and 11 scenarios were chosen. The results showed that at a constant mill filling, the power draw was changed with changing the ball size distribution and for all mill fillings the maximum power draw occurred when the fraction of small balls was between 30-40%. The effect of ball size distribution increased with increasing mill filling and for the mill filling of 35%, the ball size distribution had the maximum effect on the power draw. When the mill charge contained mono-sized balls, the ball flow regime inside the mill transited to the cataracting and impact breakage was the main breakage mechanism. Increasing the fraction of big balls from 0 to 70% led the flow of balls into the cascading regime and breakage mechanism to attrition.

Opis:
Computerized milling process is widely used in product manufacturing. Although manufacturing has gradually become highly-automated, the selection of machining conditions still remains an ever-present challenge in the process. To provide some findings contributable for the process planning, this study focuses on ball and filleted end milling. After brief explanations were given to the path interval determinations in both milling processes, the experiments were conducted to verify and characterize each procedure. The results of computational procedures showed good agreement with the experimental ones. Then, material removal rate and cutting force were analytically proposed for effective selection of machining conditions. The following findings were obtained from the demonstrations with discussion. Ball end milling required relatively large cutting force in the first tool path even though the material removal rate was comparatively small. On the contrary, filleted end mill enabled us to maintain a moderate cutting force in the first tool path even if the material removal rate expanded with increasing tool radius.

Opis:
Discovery of superconductivity of MgB2 with a critical temperature of -234 °C has offered the promise of important large-scale applications. Except for the other featured synthesis methods, mechanical activation, performed by high-energy ball mills to synthesis of bulk form of MgB2 or as a first step of wire and thin film production has considered as an effective alternative production route in recent years. The aim of the present study was to determine the effect of process variables such as the ball-to-powder weight ratio (BPR), size of ball, milling time, annealing temperature and contribution of process control agent (toluene) on the product size, morphology and conversion level of precursor powders to MgB2 after subsequent heat treatment. Although, the test results revealed relatively lower weight percent of MgB2 phase formation compared with the literature, the reduced milling time, BPR and sinterability of pre-alloyed powder to MgB2 at lowered temperature (630 °C) enhanced the applicability of mechanical alloying with SPEX mill.

Opis:
It has been observed by many authors that the breakage rates of coarse particles in a ball mill slow down with increasing grinding time and deviate from the first order. In this paper it is intended to find out whether the breakage rates of coarse particles obey second-order kinetics or not. For this purpose, quartz, limestone, iron ore and a mixture of quartz/limestone (weight ratio of 1:1) were selected as a ball mill feed. The first-order breakage rate was determined for the four particle sizes of quartz, limestone, iron ore and the mixture of quartz/limestone. Results indicating good first-order kinetics were obtained with the fine-sized particles (-1.2+1 mm, -0.6+0.42 mm). However, the coarse-sized particles (-5+4 mm, -3.15+2.5 mm) showed deviations from the first order. These coarse particles were in the abnormal breakage region. The second-order breakage rate was determined for the coarse particles (-5+4 mm, -3.15+2.5 mm). It can be seen that, for both sizes and all the materials, the second-order plot had better fit than the first-order plot. Also, it can be concluded that the second-order kinetics could model the breakage of coarse particles better than the first-order kinetics, and the validity of the second-order breakage rate was increased with increasing particle size. However, it is suggested to examine the validity of the second-order breakage rate kinetics for other materials and particle sizes.

Opis:
The design of the grinding circuits and the control of the transferring load in the ore preparation plants are of great importance from a technical and economic point of view. The importance of the circulating load for grinding process is well known and stated in the literature. However, there are not many studies on the effect on the following processes. In this study, the effect of the circulating load on both the grinding capacity and the subsequent flotation process was investigated at laboratory scale. Copper ore was used in the experiments. The circulating load was adjusted by changing the residence time of the material in the mill. Then, flotation experiments were carried out with the materials obtained at different circuit loads. The results showed that the grinding capacity can be increased up to 180% by optimizing the circulating load and it will positively affect the flotation performance. It was observed that a concentrate with the highest recovery for the same Cu grade was obtained with CLR of 150 % when compared to flotation recoveries through various CLRs. It is suggested that the circulating load should not be evaluated only in terms of the grinding process, but also the subsequent processes should be considered. Future studies in this area may contribute to industrial applications.

Opis:
The first step towards condition based maintenance of the milling plant is the implementation of on- line condition monitoring of the mill. The following paper pr esents and analyses methods of monitoring the key performance factors of a vertical spindle mill that is suited for implementation on older power stations, i.e. the quantity (mass flow rate) and quality (particle fineness) of the pulverised fuel produced by the mill. It is shown herein that the mill throughput can be monitored on-line using a simple mill energy balance that successfully predicts the coal the roughput within 2.33% as compared to a calibrated coal feeder. A sensitivity analysis reveals that the coal moisture is a critical measurement for this method to be adopted as an on-line mass flow monitoring tool. A laser based particle size analyser tool was tested for use in the power plant environment as an on-line monitoring solution to measure pulverised fuel fineness. It was revealed that several factors around the set-up and operation of the instrument have an influence on the perceived results. Although the instrument showed good precision and repeatability of results, these factors must be taken into account in order to improve the accuracy of the reported results before the instrument can be commissioned as an on-line monitoring solution.

The purpose of this study was to develop an effective method for real-time detection of the state of cutting tools used in end milling of hard brittle materials. Cutting tests were performed to identify parameters that are useful in monitoring micro tool wear in glass milling. A specific component of the cutting force was found to be related to the progression of tool wear. Furthermore, using fast Fourier transform (FFT) analysis, the peak amplitudes of the cutting forces were found to occur at a specific frequency.

Opis:
The verification of the desired capacity increase in the grinding circuits is performed by simulation studies as they suggest accurate and fast alternatives compared to expensive and labor-intensive methods, particularly for the evaluation of situations that require investment. In this study, simulation was used to evaluate the alternatives that can be made to increase the capacity from 38.86 tph to 90 tph in a grinding circuit where copper slag is autogenously milled. The slag sample was characterized by drop weight and abrasion tests to describe the breakage in autogenous (AG) milling. The performances of the existing circuit and equipment were determined by a comprehensive sampling study, and modeling studies were carried out to form the basis of the simulations. Simulation scenarios were evaluated as investment free and investment requiring alternatives. In the investment free option changing fresh feed size distribution was examined however, capacity could be increased up to only 42 tph. In investment option, increasing the mill motor capacities was simulated and 90 tph target throughput was provided. This result was validated in the plant by replacement of mill motors of AG and pebble mill for 1000 kW and 750 kW, respectively.

In classification one of the methods used to evaluate the effectiveness of classifier’s work is to create the partition curve, which determines the size of the classified particles and characterizes the accuracy of the process. The article presents the results of experiments showing the efficiency of classification in the inertial classifier, designed specifically for the electromagnetic mill. The paper presents the results of tests in order to determine the possibility of controlling the classification by changing the transport air stream flow. In order to verify and assess the classifier work, a series of experiments with different opening level of additional air damper was performed. The results allow thorough assessment of the effectiveness and efficiency of the device and facilitate the optimization of the grinding process by establishing an appropriate control algorithm as well as the air flow in classifier.
