Centrifugal slurry pump vibration analyze
(GMIT, 2019) Zolboo Batsaikhan; Ariunbolor Purvee; Odbileg Norovrenchin; Gureragchaa
This bachelor work is a part of the “Slaked lime system” problem developing project and it is aimed to discover and modify a slurry pump overheat problem occurred at Oyu Tolgoi mine. And it is searched for ways to reduce overheating so that the mining operation could have benefit in numerous ways. The main objective of this work is to analyze vibration of the pumps, as it is experiencing overheating problem in the bearing area. Problem causing roots would be detected and analyzed for optimal solutions. Design modification would be done as one of the result of this research work.
Designing an off-grid, battery-backed solar PV system for a gable roof cottage in Mongolia
(GMIT, 2023) Dashnamjil Tuvshintur; Ariunbolor Purvee; Nyamdulam Renten
Global energy consumption is anticipated to increase by approximately 50% between 2018 and 2050, with the trend echoed in Mongolia, where annual electricity and heating demands are forecasted to grow at rates of 4.4% and 3.4% respectively up to 2030. This is prompting a transition towards renewable energy sources. The research focused on examining the feasibility of using off-grid photovoltaic (PV) solar systems for gable-roofed houses in Mongolia.
Life Time Evaluation of Laser-Coated Pump Parts in the Mineral Processing Industry
(GMIT, 2019) Dulguun Narmandakh; Ariunbolor Purvee; Battulga Nasanjargal
This thesis aims to choose the best laser coating powder system among experimented materials and to estimate the useful life of specific laser coated pump parts. Slurry pumps in mineral processing are parts which erode away very quickly. Erosion is dominantly caused by abrasion from fine particles of the ore. Due to its cause, the process of erosion takes place on impeller blades and cover plates which have direct contact with the slurry
Possibility of Alteration of the ore mechanical property for improvement of the transfer chute design problems
(GMIT, 2018) Tengisdulguun Tumenjargal; Ariunbolor Purvee; Ariunbold Puntsag
The mining industry has been expanding rapidly in Mongolia for last 2 decades. As a result, many problems are arising which require solutions from Mongolian engineers. Effectiveness and productivity of copper mining industry depend on appropriate actions and processes of various types of devices, techniques and machineries, which are used at mining sites. One of these important devices is a transfer chute.
Real-time volumetric measurement of grinding media of SAG mill
(GMIT, 2020) Nauryzbyek Byekyetkhan; Ariunbolor Purvee; Sungchil Lee; Munkhbaatar Purevdash
This research work aimed to investigate the “Real-time volumetric measurement of grinding media of semi-autogenous (SAG) mill” by using an online-based model. Oyu Tolgoi (OT) mine copper concentrator is located in South Gobi province, south part of Mongolia. SAG mills are often taken as the object of optimization studies because they are a type of equipment that consumes large amounts of energy. Its size reduction stage includes one primary crusher which feeds two SAG mills (11.58m diameter x 7m length) with the following three ball mills (7.32m diameter x 11.32m length). After sag mill, comminuted products pass through a trommel screen in which over and undersize materials its oversize part is circulated into SAG mill and undersize part is conveyed to hydro-cyclone to further process.
Reducing of vibration influence on auger drilling rig (SBR-160A-24)
(GMIT, 2019) Batsuuri Dalainyam; Ariunbolor Purvee; Baljinnyam Erdenetsoo
The main objective of this work is to analyze the vibration, to find the sources and to examine for optimal solutions in SBR-160A-24 auger drilling rig. Design and modelling are based on result of this research work
Study on Water hammer in Lime Slurry Pipeline
(GMIT, 2019) Turtsetseg Nanjid; Odbileg Norovrenchin; Ariunbolor Purvee
The present study is intended to examine the effect of water hammer in milk of lime distribution system at Oyu Tolgoi LLC. The company produces copper concentrate and the flotation process for the copper concentrate production requires slaked lime in order to control pH value. It is essential to prevent system failures because of safety and economic purpose.
Transfer Chute Design Modification Using Discrete Element Method
(GMIT, 2018) Sukhbat Altangerel; Ariunbolor Purvee; Odbileg Norovrenchin; Gurragchaa Tumur
This bachelor work is aimed to modify currently operating transfer chute design with the help of bulk material simulation. The use of Discrete Element Method (DEM) allows the engineers to design and/or optimize bulk material handling facilities with the great precision.
