General Layout Of Crushing Plant And Its Maintenance Terms

In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.This paper addresses the critical design parameters as well as the consideration of ore characteristics, geographical location, climatic conditions, expected operational life, expansion potential, safety, environment, and operability and maintainability.The fundamental goal for the design of a crushing plant is an installation that meets the required production requirements, operates at competitive cost, complies with today's tough environmental regulations, and can be built at a reasonable price despite the rising costs of equipment, energy and construction labor.There are three main steps in designing a good crushing plant: process design, equipment selection, and layout.The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.Crushing plants must be designed for ease of access and maintainability if they are to meet their production goals.Keeping maintenance requirements to a minimum helps achieve higher overall operating availability.Scheduled preventive maintenance at crushing plants involves a number of elements, including: crusher wear parts, screen decks, feeder wear parts, conveyor skirting and adjustment, oil and lubrication, conveyor belt repair, visual inspections, electrical and instrumentation adjustments.Building for cold-weather operations is very challenging, as is designing a plant in a desert environment.This is particularly true when year-round operation is required.Seasonal variations can change ore moisture content, so the crushing plant must be adaptable to changes in the material flow characteristics.Higher moisture requires greater angles of withdrawal, and stoneboxes must be designed to avoid plugging.The crushing plant equipment itself must be adjustable to climatic changes; for example, screen decks must be designed to maintain production, possibly by using wire mesh during the wet season and plastic during the dry.Vary screen deck types dependent on seasons and material characteristics to achieve maximum passing through deck openings.Equipment suppliers are offering ever-larger primary crushers, with 1,800 mm (72 in) gyratories expected soon, as well as secondary and tertiary machines of up to 3,000 mm (120 in).Primary crushers: http://www.Hxjq-crusher.Com/1.Html sand washer: http://www.Hxjq-crusher.Com/16.Htmljaw crushers: http://www.Crusher-machine.Com/1.Html.
