A classifier equipment with overflow end spiral completely submerged below the liquid surface.
Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
A hoist is a device used for lifting or lowering a load by means of a drum or liftwheel around which rope or chain wraps. It may be manually operated electrically or pneumatically driven and may use chain fiber or wire rope as its lifting medium. The most familiar form is an elevator the car of which is raised and lowered by a hoist mechanism.Most hoists couple to their loads using a
Highgrader One who steals rich ore especially gold from a mine. Hoist The machine used for raising and lowering the cage or other conveyance in a shaft. Ore pass Vertical or inclined passage for the downward transfer of ore connecting a level with the hoisting shaft or a lower level.

In underground mining a hoist or winder is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors historically with direct current drives utilizing Ward Leonard control machines and later solidstate converters () however modern large hoists use alternating current drives that are variable frequency controlled.

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century coal has yielded its place to petroleum and natural
Published since the 1870s this report contains production statistics mine names locations owner information and accident statistics. Prior to the mid1880s the reports for anthracite and bituminous coal were produced by separate agencies therefore early reports for bituminous coal are available as part III "Industrial Statistics" of the Annual Report of the Bureau of
Drift mine An underground coal mine in which the entry or access is above water level and generally on the slope of a hill driven horizontally into a coal seam. Drill A machine utilizing rotation percussion (hammering) or a combination of both to make holes. If the hole is much over 0.4m in diameter the machine is called a borer.
