SYSTEMS AND METHODS FOR ASCERATINING INTENT FLOW OF MATERIAL FROM ROKSH SEPARATOR OF PELLET PLANT

TECHNICAL FIELD
[0001] The present disclosure, in general, relates to analytical systems, and, more particularly, to systems and methods method of ascertaining an intent flow of a material from a roksh separator of a pellet plant.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[0003] Pelletizing is an agglomeration process whereby the fine iron ore particles are converted into spherical bodies with size ranging from 8 to 18 mm. These spherical bodies having an appropriate physical, chemical and metallurgical properties for use in steel mill's reduction reactors.
[0004] The quality of the product yielded by the pelletizing process has direct relation with the material size fed to the process, and it is suitable that at least 50% of the raw material charged to the process have a size less than 0.40 mm (325 mesh) and a specific surface of 1200 cm2/g. Usually, the ore fines employed in pelleting have a granulometry 100% less than 0.149 mm (100 mesh), however only 30 to 45% being less than 0.044 mm (325 mesh). Therefore, in order to adapt the granulometric characteristics and specific surface of the ore fines to the pelleting process requirements it becomes necessary to submit the ore fines to a crushing stage to reduce the particles size.
[0005] In the conventional pelletizing process, the reducing of size (crushing and grinding) of the iron ore finer is achieved by grinding in a tubular ball mill wherein steel balls or truncated steel cones are usually employed to help with the grinding operation or as a grinding medium. The output of the tubular ball mill is feed to a roksh separator to separate the reduced size iron ore finer from the other. The other non-reduced size iron ore finer is again supplied back to the tubular ball mill through a reject air slide connecting the output of roksh separator with feed chute of the tubular ball mill. However, apart from regular iron ore supply, such additional iron ore supply from the reject air slide may not be completely feed to the tubular ball mill. This may lead to jamming of the reject air slide. Also, when the tubular ball mill is feed with additional iron ore supply, further components including drive means of the tubular ball mill may fail.
[0006] Therefore, there is a need in the state of the art for a system to ascertain the flow of iron ore after exit from the roksh separator so as to control the regular iron ore supply to the tubular ball mill.

OBJECTS OF THE DISCLOSURE
[0007] Some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed hereinbelow.
[0008] It is a general object of the present disclosure to provide an analytical system to periodically monitor the flow of iron ore after exit from the roksh separator so as to control the regular iron ore supply to the tubular ball mill.
[0009] It is another object of the present disclosure to provide an analytical system which provides indication about the intent flow of the iron ore after exit from the roksh separator.
[0010] These and other objects and advantages of the present invention will be apparent to those skilled in the art after a consideration of the following detailed description taken in conjunction with the accompanying drawings in which a preferred form of the present invention is illustrated.

[0035] Embodiments explained herein pertain to a pelleting process of reducing the size (crushing and grinding) of the iron ore finer. For such crushing and grinding of the iron ore finer, the iron ore finer are supplied from a raw material handling system 102 to a rotary dryer 104, as shown in FIG. 1 illustrating a drying and grinding circuit of a pellet plant.
[0036] During drying, the rotary dryer 104 is rotated with a main drive 106. In an aspect, the main drive 106 is connected to the rotary dyer 104 through a girth gear 110 mounted on outer periphery of the rotary dyer 104.
[0037] While rotating, the rotary dryer 104 receives a hot gas from a hot gas generator 108. In an aspect, the hot gas is formed by combination of core air, blast furnace gas, CO gas, and combustion gas inside the hot gas generator 108.
[0038] After a time period of, say, 15 minutes, the rotation of the rotary dryer 104 is stopped and the dried ore are moved out of the rotary dryer 104 through its outlet 112. From the outlet 112, the dried ore is supplied to a bucket elevator 114 through a product conveyor 116. From the bucket elevator 114, the dried ore is supplied to a dried ore bin 118 having a capacity of 69 tones.
[0039] The dried ore moves out of the dried ore bin 118 through a controllable slide gate (SG) 120. After moving out of the dried ore bin 118, the dried ore lands on a weigh feeder 122 from where the dried ore is supplied to a feed chute 124 of a tubular ball mill 126. As mentioned above, in the tubular ball mill 126, steel balls or truncated steel cones are usually employed to perform grinding operation on the Dried ore feed inside the tubular ball mill 126. For agitating the steel balls or truncated steel cones for grinding of the dried ore, the tubular ball mill 126 is rotated about its longitudinal axis by a mill drive 128 connected to a girth gear mounted on outer periphery of the tubular ball mill 126. After milling or grinding for about, say, 15 minutes, the ore is outputted either to a bucket elevator 130 though an air slide 132 or to a roksh separator 134. That is, the ores which are not grinded properly and having non-reduced size falls downwards to the bucket elevator 130 though an air slide 132, and other ores move upside towards the roksh separator 134. In an aspect, the non-reduced size ores received in the bucket elevator 130 are routed to the roksh separator 134 through another air slide 136. Thus, all the ores outputted from the tubular ball mill 126 will reach, directly or indirectly, the roksh separator 134.
[0040] In the roksh separator 134, an air supply is received mill ID fan (suction pressure and recirculation air) as to separate the reduced size or ores from non-reduced size of ores. The reduced size of ores are supplied further to a bag filter 140 from where the ores reach to ground silo through a bucket elevator 148. However, the non-reduced size of the ores are supplied back to the feed chute 124 of the ball mill 126 through the rejects air side 150. The rejects air side 150 connects the reject output of the roksh separator 134 with the feed chute 124 of the tubular ball mill 126 so as to regrind the non-reduced size of ores.
[0041] However, as mentioned earlier, apart from regular ore supply from the dried ore bin 118, such additional iron ore supply from the rejects air slide 150 may not be completely feed to the tubular ball mill 126. This may lead to jamming of the rejects air slide 150.
[0042] Also, when the tubular ball mill 126 is feed with additional ore supply, further components including air slide 132 towards the bucket elevator 130 may also get jammed due to additional output from the tubular ball mill 126.
[0043] Furthermore, in case the quantity of the reduced size of ores that are supplied to the bag filter 140 is high than the non-reduced size of ores supplied back to the tubular ball mill 126, the product air slide 146 may get jammed due to receipt of high quantity of the reduced size of ores.
[0044] To resolve these issues of jamming of multiple air slides during different conditions, the present disclosure proposes to dispose a number of sensors in the system to measure various parameters related to material (iron ore) flow in the drying and grinding circuit of the pellet plant.
[0045] For instance, as shown in FIG. 2, sensors 202, 203, and 204 are implemented at inlets and outlets of the roksh separator 134 and the bag filter 140. These sensors 202, 203, 204 are used to sense input and output pressure at inlets and outlets of the roksh separator 134 and the bag filter 140. In an aspect, the sensor 202 senses input pressure P2 at an inlet of the roksh separator 134 and the sensor 203 senses an output pressure P3 at an outlet of the roksh separator 134. Further, the output pressure P3 sensed by the sensor 203 is also the input pressure P3 at an inlet of the bag filter 140; however, the sensor 204 senses an output pressure P4 at an outlet of the bag filter 140.
[0046] In an aspect, the pressure P2, P3, and P4 sensed by the respective sensors 202, 203, and 204 are provided to a computing system 300 shown in FIG. 3. In an aspect, sensors 202, 203, and 204 are connected to the computing system 300 though a communication network. The communication network may be a single network or a combination of multiple networks. The communication network may include one or more area networks, such as a local area network (LAN), a wide area network (WAN), an intranet, the internet, or any other type of network. In an example, the network may include a mobile communication network, for example, 2G, 3G, 4G, or 5G mobile communication network. The communication network may be coupled to one or more other networks, thereby providing coupling between a greater number of devices. Such can be the case, for example, when networks are coupled together via the Internet.
[0047] In an aspect, the computing system 300 includes a processor(s) 302, an interface(s) 304, and a memory 306. The processor(s) 302 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that manipulate data based on operational instructions. Among other capabilities, the one or more processor(s) 302 are configured to fetch and execute computer-readable instructions and one or more routines stored in the memory 106. The memory 306 may store one or more computer-readable instructions or routines, which may be fetched and executed to manage warehouse over a network service. The memory 306 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like.
[0048] The interface(s) 304 may include a variety of interfaces, for example, interfaces for data input and output devices referred to as I/O devices, storage devices, and the like. The interface(s) 304 may facilitate communication of the system 300 with various devices coupled to the system 300. The interface(s) 304 may also provide a communication pathway for one or more components of the system 300. Examples of such components include, but are not limited to, processing engine(s) 308 and data 310. The data 310 may include data that is either stored or generated as a result of functionalities implemented by any of the components of the processing engine(s) 308.
[0049] The processing engine(s) 308 may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing engine(s) 108. In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processing engine(s) 308 may be processor executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processing engine(s) 308 may include a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement the processing engine(s) 308. In such examples, the computing system 300 may include the machine-readable storage medium storing the instructions and the processing resource to execute the instructions or the machine-readable storage medium may be separate but accessible to the computing system 300 and the processing resource. In other examples, the processing engine(s) 308 may be implemented by electronic circuitry.
[0050] In an aspect, the computing system 300 may include other engine(s) 312. The other engine(s) 312 may implement functionalities that supplement applications or functions performed by the computing system 300 or the processing engine(s) 308.
[0051] In operation, the processing engine 308 is adapted to receive input pressure P2 of the roksh separator 134 from the sensor 202 disposed at the inlet of the roksh separator 134, an output pressure P3 of the roksh separator 134 from the sensor 203 disposed at the outlet of the roksh separator 134, an input pressure P3 of the bag filter 140 from the sensor 203 disposed at the inlet of the bag filter 140, and an output pressure P4 of the bag filter 140 from a sensor 204 disposed at the outlet of the bag filter 140.
[0052] Following this, the processing engine 308 computes a differential pressure dPR across the roksh separator 134 based on the input pressure P2 and the output pressure P3 across the roksh separator 134, and computes a differential pressure dPB across the bag filter 140 based on the input pressure P3 and the output pressure P4 across the bag filter 140. Thereafter, the processing engine 308 computes a further differential pressure (dPR - dPB) between the differential pressure dPR across the roksh separator 134 and the differential pressure dPB across the bag filter 140, so as to ascertain the intent flow of material (iron ore).
[0053] In an aspect, the processing engine 108 ascertains the intent flow of the material as additional flow in rejects air slide 150 connected to one of the outputs of the roksh separator 134 based on a negative value of the computed further differential pressure (dPR - dPB).
[0054] In an aspect, the processing engine 108 ascertains the intent flow of the material as additional flow in the bag filter 140 connected to one of the outlets of the roksh separator 134 based on a positive value of the computed further differential pressure (dPR - dPB).
[0055] In an aspect, the processing engine 108 computes the further differential pressure (dPR - dPB) at regular time intervals of, say, 5 minutes, and provides its recommendation for throughput change based on the further differential pressure (dPR - dPB) after a predefined time period of, say, 30 minutes.
[0056] Thus, with the computation of the positive and negative values of the further differential pressure (dPR - dPB), the processing engine 108 though the interface 304 can recommend a user about throughput change. For instance, as shown in FIG. 4, the processing engine 108 or the computing system 300 is prompting the user or the operator to increase the feed by 5 when the existing feed is 526 tone per hour (TPH). Such prompt and recommendations from the system 300 allows the operator of the drying and grinding circuit of the pellet plant to appropriately control the feed for drying and grinding circuit so that no air slide gets jammed during the operation.
[0057] FIG. 5 illustrates a method 500 of ascertaining an intent flow of a material from a roksh separator 134, according to an implementation of the present disclosure. The order in which the method 500 is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any appropriate order to carry out the method 500 or an alternative method. Additionally, individual blocks may be deleted from the method 500 without departing from the scope of the subject matter described herein.
[0058] The method 500 can be performed by programmed computing devices, for example, based on instructions retrieved from the non-transitory computer-readable medium or non-transitory computer-readable media. The computer-readable media can include machine-executable or computer-executable instructions to perform all or portions of the described method. The computer readable media may be, for example, digital memories, magnetic storage media, such as magnetic disks and magnetic tapes, hard drives, or optically readable data storage media.
[0059] At block 502, the method 500 includes receiving, at a processing engine 308 of a system 300, an input pressure P2 of the roksh separator 134 from a sensor 202 disposed at an inlet of the roksh separator 134 and an output pressure P3 of the roksh separator 134 from a sensor 203 disposed at an outlet of the roksh separator (134).
[0060] At block 504, the method 500 includes receiving, at the processing engine 308, an input pressure P3 of the bag filter 140 from the sensor 203 disposed at the outlet of the roksh separator 134 and an output pressure P4 of the bag filter 140 from a sensor 204 disposed at an outlet of the bag filter 140.
[0061] At block 506, the method 500 includes computing, at the processing engine 308, a differential pressure dPR across the roksh separator 134 based on the input pressure P2 and the output pressure P3 across the roksh separator 134.
[0062] At block 508, the method 500 includes computing, at the processing engine 308, a differential pressure dPB across the bag filter 140 based on the input pressure P3 and the output pressure P4 across the bag filter 140.
[0063] At block 510, the method 500 includes computing, at the processing engine 308, a further differential pressure (dPR - dPB) between the differential pressure dPR across the roksh separator 134 and the differential pressure dPB across the bag filter 140, so as to ascertain the intent flow of material from the roksh separator 134.
[0064] In an aspect, based on a negative value of the computed further differential pressure (dPR - dPB), the ascertainment of the intent flow of the material as additional flow in rejects air slide 150 connected to one of outlets of the roksh separator 134.
[0065] In an aspect, based on a positive value of the computed further differential pressure (dPR - dPB), the ascertainment of the intent flow of the material as additional flow in the bag filter 140 connected to one of outlets of the roksh separator 134.
[0066] In an aspect, the method further includes computing the further differential pressure (dPR - dPB) at regular time intervals, and recommending throughput change based on the further differential pressure (dPR - dPB) after a predefined time period.
[0067] Thus, with the implementation of the method 500 of the present subject matter, the system 300 provides recommendations to the operator of the drying and grinding circuit of the pellet plant to appropriately control the feed for drying and grinding circuit so that no air slide gets jammed during the operation.
[0068] The above description does not provide specific details of the manufacture or design of the various components.
