Abstract: An enhanced retractable flow discharge extension is configured for use in a coal pulverizer having a classifier system including a feedpipe to deliver from above raw coal to a pulverizing structure and a classifier cone positioned around the feedpipe to collect oversized coal for the pulverizing structure. The enhanced retractable flow discharge extension is configured to deliver oversized coal to the pulverizing structure and has a conical extension portion having an inlet end configured to be contiguous with the classifier cone outlet, a fixed cylindrical portion having an upper end contiguous with an outlet end of the conical extension portion, a movable cylindrical portion having a circumference larger than a circumference of the fixed cylindrical portion, the movable cylindrical portion being movably attached to the fixed cylindrical portion, and a distal portion movably attached to the movable cylindrical portion, the distal portion having a straight portion and a tapered portion.

Abstract: The present disclosure relates to a rock processing apparatus (12) for crushing and/or sorting granular mineral material (M) according to size, comprising:
a material feeding apparatus (22) including a material buffer (24),
at least one working unit of: at least one crushing apparatus (14) and at least one screening apparatus (16, 18),
at least one conveyor apparatus (26, 32) for conveying material between two apparatus components,
at least one discharge conveyor apparatus (29, 42, 46) for conveying processed material onto a stockpile (30, 44, 48),
a control unit (60),
at least one stockpile sensor (96, 98) for detecting at least one state and/or a change over time of a size of the stockpile (30, 44, 48), the stockpile sensor (96, 98) being connected to the control unit (60),
at least one output device (66) for outputting information, the output device (66) being connected to the control unit (60).
The control unit (60) is designed to ascertain, in an operation with a discontinuous reduction of the at least one stockpile (30, 44, 48), on the basis of the at least one detection signal, a piece of reduction time information about an execution time of a future reduction of the stockpile (30, 44, 48), wherein the output device (66) is designed to output the ascertained reduction time information.-

Abstract: A method for continuous aeraulic separation of particulate materials consisting of a mixture of particles that is heterogeneous in both particle size and density is provided. The method includes grinding particles of materials, generating a gas stream conveying the ground particles, first aeraulic separation on the gas stream in order to separate the particles it contains into a first fraction consisting of the coarsest particles with variable densities and a second fraction consisting of the finest particles. A second aeraulic separation is performed on the first fraction in order to separate the particles that it contains into a third fraction consisting of the coarsest and/or most dense particles and a fourth fraction consisting of the least coarse and/or the least dense particles. A re-injecting of the third fraction or the fourth fraction at the inlet of the grinding is performed while simultaneous recovery of the second fraction as well as the fourth fraction or the third fraction, respectively, as output products.

Abstract: A method includes separating, in a first stage of separating, crushed ore material by size into a first fines stream and a first coarse stream; grinding the first coarse stream in a second stage of grinding; feeding the product of the second stage of grinding back to the step of separating; feeding the first fines stream from the step of separating to a recovery circuit; producing a rejected stream from the recovery circuit of crushed ore material that does not meet the target mineral size; separating, in a second stage of separating, the rejected stream from the recovery circuit into a second fines stream and a second coarse stream; grinding the second coarse stream in a third stage of grinding; and feeding the product of the third stage of grinding back to the recovery circuit.
