Coal Handling and Equipment Selection coal handling and equipment selection
This user-friendly book is of relevance to students pursuing undergraduate course in mining and mineral processing engineering when selecting mining equipment, which is a function of mine plan. Proper choice of mining equipment is critical for technological, economical and safety criteria that must be satisfied during mining and material handling; which rely mainly on mobile drill rigs, hydraulic shovels, front-end loaders, scrapers and haul trucks to extract ore and initiate ore processing. Large mining operations require larger equipment capacity to maintain the mine plan while simultaneously considering mining constraints that often influence the mining operations. Besides its simplicity, the book is replete with equipment/machinery selection for both surface and underground mining activities which students, researchers and professionals should find both stimulating and useful.

Larry Thomas Coal Geology coal handling and equipment selection
Coal Geology, second edition, offers a thoroughly revised and updated edition of this popular book which provides a comprehensive overview of the field of coal geology. Coal Geology covers all aspects of coal geology in one volume, bridging the gap between the academic aspects and the practical role of geology in the coal industry. The object of the book is to provide the reader with a with a description of the origins of coal together with the physical and chemical properties of coal and coal petrology before proceeding to cover all areas of coal exploration, production and use. Bridges the gap between academic aspects of coal geology and the practical role of geology in the coal industry Examines historical and stratigraphical geology, together with mining, environmental issues, geophysics and hydrogeology and the marketing of coal Defines worldwide coal resource classifications and methods of calculation Addresses the alternative uses of coal as a source of energy, together with the environmental implications of coal usage Includes improved illustrations including a colour section Offers a global approach covering expanding fields in America, China and India The truly global approach, drawn from the international experiences of the author, recognizes the growing role of coal use in emerging markets. With fully revised coverage of the latest modelling techniques, environmental legislation, equipment and recording methods, the second edition offers a truly invaluable resource for anyone studying, researching or working in the field of coal geology, geotechnical and mining engineering and environmental science.

Low Cost Automation And Effective Material Handling Systems coal handling and equipment selection
The book is an effort to amalgamate the two concepts of LOW COST AUTOMATION and MATERIAL HANDLING by implementing very simple and innovative ideas for achieving effective material handling. The book has two parts; a case study to demonstrate low cost automation by conceptualizing, designing and fabricating a Job Auto Loader, whereas second part demonstrates effective material handling using several innovative ideas of improvising upon the existing material handling system.

Low Cost CNC Automation coal handling and equipment selection
The term automation has many definitions. Apparently, it was first used in the early 1950s to mean automatic handling of materials, particularly equipment used to unload and load stamping equipment. It has now become a general term referring to services performed, products manufactured and inspected, information handling, materials handling, and assembly—all done automatically (i.e.as an automatic operation without human involvement). At present, in order to solve the low efficiency and high cost problem in the process of CNC machines, Nowadays Manufacturers have always faced the challenge of constantly needing to find new ways to reduce the cost of their loading and unloading processes in machining centers. The project title is “LOW COST AUTOMATION FOR MACHINING CENTER” new concept in Machine tool industry for continuous production, less cycle time and more accuracy. This project contains the auto loading plate, unloading plate, hydraulic fixture and rotary table controlling with PLC Ladder logic controller.It is a simple automation system for auto load and unload component to vertical CNC Machining center as compared to the gantry auto load and unload system.

Performance Characteristics of Slurry Pumps with Coal Ash coal handling and equipment selection
Thermal power plants generate more than half of the world’s electric power by burning millions of tonnes of coal and simultaneously produce large quantity of coal ash. Slurry pipelines are commonly used across the world for the transportation of coal ash (fly ash and bottom ash) from the plant to the ash ponds in thermal power plants. Slurry pumps are extensively used in the hydraulic transportation of solids through pipes in the form of slurry over short/medium distances. Today a wide range of slurry pumps are available and they are generally classified into two main categories namely positive displacement and centrifugal type. These pumps differ considerably in design and construction and hence the performance of these pumps changes depending upon the flow behavior of the slurry. The experimental studies carried out are aimed at generating extensive data and provide some insight into the existing gaps in the knowledge on the performance of centrifugal and progressive cavity screw pumps handling highly concentrated slurries.
