Abstract

A method and system for processing mineral material. A first output fraction from a mineral material screening device MMSD (410) is received (600) onto a first transfer conveyor (110) that is perpendicular to a flow direction of the MMSD (410). The first transfer conveyor (110) is operated (601) in either a first perpendicular direction or in a second perpendicular direction of the flow direction of the MMSD (410), for transferring received first output fraction accordingly to the first or second perpendicular direction. A second output fraction is received (602) from the MMSD (410) onto a second transfer conveyor that is perpendicular to the flow direction of the MMSD (410). The second transfer conveyor is operated (603) in either the first perpendicular direction or in the second perpendicular direction for transferring received second output fraction accordingly to the first or second perpendicular direction. The mineral material transferred to the first perpendicular direction is conveyed (604) by a first secondary conveyor (130). The mineral material transferred to the second perpendicular direction is conveyed (605) by a second secondary conveyor (140).

Description

MINERAL MATERIAL SCREENING OUTPUT TRANSFER SYSTEM
TECHNICAL FIELD
The present disclosure generally relates to a mineral material screening output transfer system. The disclosure relates particularly, though not exclusively, to a controllable transfer of screened fractions to two or more conveyors.
BACKGROUND
This section illustrates useful background information without admission of any technique described herein representative of the state of the art.
Mineral material screening classifies mineral material by particle size using one or more — screen decks. The screened fractions are suited for different uses and typically directed to different destinations. Often, screening output is directed to two or more different heaps.
Sometimes one or more fractions are redirected to crushing, which may take place in a combined screening and crushing plant.
It is sometimes desirable to change routing of screening output from one conveyor to — another. Sometimes it is also desired to combine two or more fractions to one conveyor. It is an object of this invention to enhance screening output handling or to at least provide a new technical alternative.
SUMMARY
The appended claims define the scope of protection. Any examples and technical descriptions of apparatuses, products and/or methods in the description and/or drawings not covered by the claims are presented not as embodiments of the invention but as 3 background art or examples useful for understanding the invention.

DETAILED DESCRIPTION
In the following description, like reference signs denote like elements or steps.
Fig. 1 illustrates a simplified drawing of a system 100 according to an example embodiment in a first operation state. The system 100 comprises a first transfer conveyor 110. The first transfer conveyor 110 is perpendicular in relation to a flow direction of the mineral material screening device. The flow direction may be understood as a longitudinal flow direction; the movement through a screen medium or media and sloping downwards along the screen medium or media is not relevant for the flow direction.
The system 100 further comprises a second transfer conveyor 120. The second transfer conveyor 120 is also perpendicular in relation to the flow direction of the mineral material screening device.
The system 100 further comprises a first secondary conveyor 130 and a second secondary conveyor 140. The secondary conveyors are provided, e.g., for discharging or recycling mineral material.
The transfer conveyors are operable to move the first and second output fractions to given one or both secondary conveyors 130, 140 as desired.
Fig. 2 illustrates another simplified drawing of the system of Fig. 1 in the first operational state in which the first output fraction is transferred by the first transfer conveyor 110 to the first secondary conveyor 130, and in which the second output fraction is transferred by the — second transfer conveyor 120 to the second secondary conveyor 140.
Fig. 3 illustrates yet another simplified drawing of the system of Fig. 1 in a second operational state. Here, the second transfer conveyor 120 is operated in opposite direction than in Fig. 2 state so that both the first and second transfer conveyors 110, 120 feed the
N first secondary conveyor 130. Notably, if instead the direction of the first transfer conveyor
N 25 110 were reversed, then both first and second transfer conveyors 110, 120 would feed the
O second secondary conveyor 140. Moreover, if the directions of the of the first transfer
A conveyor 110 and of the second transfer conveyor 120 were reversed, then the first and
Ek second transfer conveyors 110, 120 would feed the second secondary conveyor 140 and a
N the first secondary conveyor, respectively. 3 30 Fig. 4 illustrates still another simplified drawing of the system of Fig. 1. Fig. 4 further
N illustrates a screening device 410, a first actuator 420 for the first transfer conveyor 110,
N e.g., an electric motor, and a second actuator 430 for the second transfer conveyor 110, e.g., an electric motor. It is also appreciated that while the two transfer conveyors may be actuated by a single motor. For example, the system may comprise first and second actuator means comprising one motor and a drive system configured to allow running both transfer conveyors to either one or another perpendicular direction.
Fig. 5 illustrates a mobile mineral material processing plant of an example embodiment. Fig. 5 5 shows a crusher 510, a recycling conveyor 520 for recycling the first fraction received from the first secondary conveyor 130, and the screening device 410. A mobile platform 530 comprises a base. The mobile platform may further comprise one or more crawler tracks; skids; wheels; and / or feet. The mobile mineral material processing plant may be self-propelling. The mobile mineral material processing plant may be towable.
